Question 1SOLAS Convention framework, amendments, and certification obligations

Under SOLAS, which instrument is issued to a ship after survey to certify that its structure, machinery and equipment comply with the Convention's applicable requirements?

  1. Continuous Synopsis Record
  2. International Tonnage Certificate
  3. Document of Compliance
  4. Cargo Ship Safety Construction Certificate Correct answer.

Explanation

SOLAS requires statutory certificates, and the Cargo Ship Safety Construction Certificate evidences compliance of hull, machinery and equipment for a cargo ship. The other documents serve different purposes under tonnage measurement, ship identification and ISM company auditing.

Question 2SOLAS Convention framework, amendments, and certification obligations

Which SOLAS chapter contains the general obligation for Contracting Governments to issue certificates and for certificates to be accepted by other Contracting Governments?

  1. Chapter I Correct answer.
  2. Chapter XI-1
  3. Chapter V
  4. Chapter II-2

Explanation

Chapter I (General Provisions) sets out survey and certification obligations, including the requirement that certificates issued under SOLAS be accepted by other Contracting Governments. Chapters II-2, V and XI-1 address fire safety, navigation safety and ship identification respectively.

Question 3SOLAS Convention framework, amendments, and certification obligations

A new cargo ship is required to hold a Cargo Ship Safety Equipment Certificate. Which item is verified in the survey leading to this certificate?

  1. The company's safety management objectives
  2. The condition and availability of life-saving appliances and fire-fighting equipment Correct answer.
  3. The financial security for wreck removal
  4. The ship's gross and net tonnage figures

Explanation

The Safety Equipment Certificate confirms compliance with the equipment requirements of SOLAS, principally life-saving and fire-fighting appliances and related arrangements. Tonnage, ISM objectives and wreck removal security are governed by other instruments.

Question 4SOLAS Convention framework, amendments, and certification obligations

How do amendments to SOLAS normally enter into force under the Convention's amendment procedure?

  1. Only after every Contracting Government deposits a written instrument of ratification
  2. Automatically on the date the amendment is adopted by the Maritime Safety Committee
  3. After approval by the United Nations Security Council
  4. By tacit acceptance unless rejected by an agreed number of Parties before a set date Correct answer.

Explanation

SOLAS uses the tacit acceptance procedure: an amendment adopted by the Maritime Safety Committee is deemed accepted on a specified date unless a set proportion of Parties object. This avoids the need for individual ratification by every State.

Question 5SOLAS Convention framework, amendments, and certification obligations

A Contracting Government wishes to apply a SOLAS requirement differently for a ship on a short international voyage. What does SOLAS generally permit?

  1. Any relaxation the flag State considers reasonable
  2. Relaxation only if the shipowner agrees in writing
  3. Relaxations or equivalents specifically provided for in the relevant chapter Correct answer.
  4. Relaxation only with prior consent of the next port State

Explanation

SOLAS permits relaxations only where the Convention itself provides for them, for example for short international voyages or through approved equivalents. A flag State cannot grant general discretionary relaxations outside those provisions.

Question 6SOLAS Convention framework, amendments, and certification obligations

Which document is issued to a passenger ship after survey and certifies compliance with SOLAS requirements on structure, machinery, equipment and radio installations?

  1. International Load Line Certificate
  2. Certificate of Registry
  3. Passenger Ship Safety Certificate Correct answer.
  4. Safety Management Certificate

Explanation

The Passenger Ship Safety Certificate consolidates the SOLAS survey and certification requirements for passenger ships. The Safety Management Certificate relates to the ISM Code, while load line and registry documents come from other regimes.

Question 7SOLAS Convention framework, amendments, and certification obligations

What is the role of a recognized organization in the SOLAS survey and certification system?

  1. It acts as an arbitration body for certificate disputes
  2. It may perform surveys and issue certificates on behalf of the flag Administration when duly authorized Correct answer.
  3. It replaces the flag Administration's legal responsibility for the ship
  4. It issues certificates only to ships of its own nationality

Explanation

Flag Administrations may delegate survey and certification work to recognized organizations such as classification societies, but responsibility under SOLAS remains with the Administration. Delegation does not transfer legal accountability for compliance.

Question 8SOLAS Convention framework, amendments, and certification obligations

Under SOLAS, what is the maximum period for which a Cargo Ship Safety Construction Certificate may be issued?

  1. Ten years
  2. One year
  3. Five years Correct answer.
  4. Two years

Explanation

SOLAS cargo ship safety certificates are issued for a period not exceeding five years, subject to the annual and intermediate survey regime. Shorter periods may apply only in specific circumstances such as short voyages or certificate extension rules.

Question 9SOLAS Convention framework, amendments, and certification obligations

A cargo ship's Safety Equipment Certificate expires while the ship is at a port where it is not surveyed. Under what condition may the Administration extend the certificate?

  1. The extension is granted only to allow the ship to complete a voyage to its intended survey port and does not exceed a limited period Correct answer.
  2. The extension may be granted for any period requested by the owner
  3. The extension is automatic and requires no Administration decision
  4. The extension is permitted only if the ship changes flag

Explanation

SOLAS allows a limited extension of a certificate in exceptional circumstances so the ship can proceed to a port for survey, provided the extension does not exceed the permitted period. It is not a general mechanism for postponing surveys indefinitely.

Question 10SOLAS Convention framework, amendments, and certification obligations

Which SOLAS chapter addresses the carriage requirements for nautical publications and voyage planning?

  1. Chapter V Correct answer.
  2. Chapter VI
  3. Chapter IX
  4. Chapter III

Explanation

Chapter V (Safety of Navigation) contains requirements for nautical publications, charts and voyage planning. Chapter III covers life-saving appliances, Chapter VI carriage of cargoes, and Chapter IX the ISM Code.

Question 11SOLAS Convention framework, amendments, and certification obligations

A shipowner asks whether a SOLAS certificate issued by one Contracting Government is valid for a ship visiting another Contracting Government's port. What is the correct position?

  1. The certificate is valid only in the issuing State's waters
  2. The certificate must be countersigned by the port State before use
  3. The port State may require the ship to be re-certified by its own Administration
  4. The certificate must be accepted by other Contracting Governments as evidence of compliance Correct answer.

Explanation

SOLAS Chapter I requires Contracting Governments to accept certificates issued by other Contracting Governments as evidence of compliance, subject to port State control verification. This mutual recognition underpins international shipping.

Question 12SOLAS Convention framework, amendments, and certification obligations

What is the purpose of the International Safety Management Code within the SOLAS framework?

  1. To set structural scantling requirements for new tankers
  2. To regulate the training and certification of seafarers
  3. To provide an international standard for the safe management and operation of ships and pollution prevention Correct answer.
  4. To establish the tonnage measurement rules for ships

Explanation

The ISM Code, made mandatory through SOLAS Chapter IX, requires companies to establish a safety management system covering safe operation and pollution prevention. Structural standards, seafarer training and tonnage rules are covered by other instruments.

Question 13SOLAS Convention framework, amendments, and certification obligations

Which SOLAS requirement applies to a ship's Continuous Synopsis Record?

  1. It must be renewed every five years alongside the safety certificates
  2. It must be kept on board and be available for inspection at all times Correct answer.
  3. It must be translated into every language of the ports the ship visits
  4. It must be issued by the recognized organization that classed the ship

Explanation

SOLAS Chapter XI-1 requires a Continuous Synopsis Record to be kept on board and made available for inspection. It records the ship's history and is not tied to the five-year certificate cycle or to classification.

Question 14SOLAS Convention framework, amendments, and certification obligations

A flag Administration discovers that a ship holding a valid SOLAS certificate no longer complies with the requirements. What action does SOLAS contemplate?

  1. The Administration may suspend, withdraw or cancel the certificate Correct answer.
  2. The Administration must refer the matter to the IMO for a decision
  3. The Administration may only issue a warning to the owner
  4. The Administration must wait until the next scheduled survey to act

Explanation

Where a ship no longer complies with SOLAS requirements, the issuing Administration may suspend, withdraw or cancel the certificate. Waiting for the next survey would leave a non-compliant ship trading with a valid certificate.

Question 15SOLAS Convention framework, amendments, and certification obligations

Which of the following is a SOLAS survey type required for cargo ships to maintain certificate validity between renewals?

  1. Radio survey every five years only
  2. Tonnage survey
  3. Dry-docking survey every ten years
  4. Annual survey Correct answer.

Explanation

Cargo ship safety certificates are maintained through annual surveys within the five-year period, with additional intermediate surveys for some certificates. Dry-docking intervals and radio surveys follow different schedules, and tonnage surveys are not a SOLAS certificate survey.

Question 16SOLAS Convention framework, amendments, and certification obligations

What does SOLAS require regarding the survey of a ship after a significant alteration affecting its structure or equipment?

  1. No survey is required until the next scheduled renewal
  2. The alteration is permitted if the owner records it in the log book
  3. The alteration must be reported only to the classification society
  4. The ship must be surveyed and, if necessary, the certificate amended or reissued Correct answer.

Explanation

SOLAS requires that significant alterations affecting compliance be surveyed so the certificate reflects the ship's actual condition. Recording the change in a log book or notifying only the class society does not satisfy the statutory survey obligation.

Question 17SOLAS Convention framework, amendments, and certification obligations

Which SOLAS chapter contains the requirements for the carriage of life-saving appliances and arrangements?

  1. Chapter III Correct answer.
  2. Chapter VII
  3. Chapter II-1
  4. Chapter XII

Explanation

Chapter III sets out life-saving appliance and arrangement requirements, including survival craft and rescue boats. Chapter II-1 covers subdivision and stability, Chapter VII dangerous goods, and Chapter XII additional safety measures for bulk carriers.

Question 18SOLAS Convention framework, amendments, and certification obligations

A Contracting Government delegates survey work to a recognized organization. Which statement best reflects SOLAS responsibility?

  1. Responsibility passes to the shipowner once the delegation is agreed
  2. The recognized organization assumes full legal responsibility for the ship's compliance
  3. Responsibility is shared equally with the next port State
  4. The Administration remains responsible for the certificate and for ensuring the organization is competent Correct answer.

Explanation

SOLAS allows delegation of surveys but the flag Administration remains responsible for certification and must ensure the recognized organization is competent. Delegation does not shift legal responsibility to the organization, owner or port State.

Question 19SOLAS Convention framework, amendments, and certification obligations

What is the function of the International Maritime Organization in relation to SOLAS?

  1. It adopts amendments to SOLAS through its Maritime Safety Committee Correct answer.
  2. It acts as the port State control authority for all member States
  3. It arbitrates disputes between shipowners and charterers
  4. It issues SOLAS certificates directly to individual ships

Explanation

The IMO is the specialized UN agency that adopts and amends SOLAS, primarily through the Maritime Safety Committee. It does not issue ship certificates, act as a port State control authority or resolve commercial disputes.

Question 20SOLAS Convention framework, amendments, and certification obligations

Which SOLAS requirement relates to the carriage of a ship's muster list and instructions for emergencies?

  1. The muster list replaces the need for on-board training
  2. The muster list must be submitted to the IMO for approval
  3. The muster list must be displayed and kept up to date with clear emergency duties Correct answer.
  4. The muster list is required only for passenger ships

Explanation

SOLAS requires a muster list to be displayed and maintained so that crew and passengers know their emergency duties. It applies to cargo ships as well as passenger ships and does not replace training or require IMO approval.

Question 21SOLAS Convention framework, amendments, and certification obligations

A new ship is intended for international voyages and must comply with SOLAS. Which statement best describes the relationship between SOLAS and the flag State's national law?

  1. The flag State implements SOLAS requirements through its national legislation and enforcement Correct answer.
  2. SOLAS applies directly to ships without any national implementation
  3. SOLAS applies only to ships flagged in States that have ratified the Load Line Convention
  4. National law may override SOLAS requirements at the owner's request

Explanation

SOLAS is a treaty binding on Contracting Governments, which give it effect through national law and enforcement. It does not operate as direct self-executing law for ships, and national law cannot be used to override Convention obligations.

Question 22SOLAS Convention framework, amendments, and certification obligations

What does the term 'equivalent' mean in the context of SOLAS certification?

  1. A certificate issued by a classification society without flag State authorization
  2. An alternative arrangement approved by the Administration that provides a level of safety at least equivalent to the requirement Correct answer.
  3. A relaxation granted automatically for ships over twenty years old
  4. A temporary certificate issued while the ship is under repair

Explanation

SOLAS permits the Administration to approve equivalents, meaning alternative arrangements that achieve at least the same level of safety as the prescribed requirement. Equivalents are not automatic relaxations or unauthorized class documents.

Question 23SOLAS Convention framework, amendments, and certification obligations

Which SOLAS chapter contains requirements for radiocommunications, including the Global Maritime Distress and Safety System?

  1. Chapter X
  2. Chapter IV Correct answer.
  3. Chapter VIII
  4. Chapter II-2

Explanation

Chapter IV covers radiocommunications and the GMDSS carriage requirements. Chapter II-2 deals with fire safety, Chapter VIII with nuclear ships, and Chapter X with high-speed craft safety measures.

Question 24SOLAS Convention framework, amendments, and certification obligations

A port State control officer finds a valid SOLAS certificate on board but clear evidence that the ship's condition does not match the certificate. What is the appropriate action under the SOLAS framework?

  1. The officer must release the ship because the certificate is valid
  2. The officer may amend the certificate to reflect the deficiencies found
  3. The officer may only record the deficiency for the next survey
  4. The officer may detain the ship until it is made compliant and notify the flag Administration Correct answer.

Explanation

Port State control may detain a ship where the certificate is not a reliable guide to its condition, and the flag Administration must be informed. Port State officers cannot amend certificates or ignore clear evidence of non-compliance.

Question 25Safety of navigation: Chapter V equipment and carriage requirements

Under SOLAS Chapter V, which document must be carried on board to record the daily movement and position of a ship engaged on an international voyage?

  1. Official log book
  2. Course recorder chart
  3. Engine room log
  4. Deck log book Correct answer.

Explanation

SOLAS V Regulation 28 requires every ship to carry a log book in which the daily movement and position of the ship is recorded, and the deck log book is the document used for this navigational record. The official log book covers statutory personnel and disciplinary matters rather than navigational positioning.

Question 26Safety of navigation: Chapter V equipment and carriage requirements

SOLAS V Regulation 19 requires a ship of 300 gross tonnage and upwards on an international voyage to carry which navigational fitting in addition to a magnetic compass?

  1. An echo sounder
  2. A sextant
  3. A gyro compass Correct answer.
  4. A course recorder

Explanation

Regulation 19 lists a gyro compass as required equipment for ships of 300 GT and upwards engaged on international voyages, with the magnetic compass as the standard baseline for smaller ships. A sextant, course recorder and echo sounder are not in that mandatory list at this tonnage.

Question 27Safety of navigation: Chapter V equipment and carriage requirements

A cargo ship of 500 gross tonnage makes international voyages. Which sound-signalling appliance does SOLAS Chapter V require it to carry?

  1. A whistle only
  2. A bell only
  3. A gong only
  4. A whistle and a bell Correct answer.

Explanation

SOLAS V Regulation 35 requires ships of 12 metres and upwards to carry a whistle, and ships of 20 metres and upwards also to carry a bell, with a gong added for ships of 100 metres and upwards. A 500 GT cargo ship therefore needs at least a whistle and a bell.

Question 28Safety of navigation: Chapter V equipment and carriage requirements

What does SOLAS V Regulation 19A concern?

  1. Carriage of electronic chart display and information systems
  2. Carriage of long-range identification and tracking Correct answer.
  3. Carriage of automatic identification systems
  4. Carriage of voyage data recorders

Explanation

Regulation 19A of SOLAS Chapter V sets out the long-range identification and tracking (LRIT) requirements, including which ships must transmit LRIT information. ECDIS, VDR and AIS carriage are addressed elsewhere within Regulation 19.

Question 29Safety of navigation: Chapter V equipment and carriage requirements

Under SOLAS V Regulation 19, at what gross tonnage does the mandatory carriage of an automatic identification system begin for ships on international voyages?

  1. 1,600 gross tonnage and upwards
  2. 500 gross tonnage and upwards
  3. 300 gross tonnage and upwards Correct answer.
  4. 10,000 gross tonnage and upwards

Explanation

Regulation 19 requires AIS for ships of 300 gross tonnage and upwards engaged on international voyages, as well as for all passenger ships and certain other categories. The 500 GT and 1,600 GT thresholds apply to other equipment items rather than AIS.

Question 30Safety of navigation: Chapter V equipment and carriage requirements

A new passenger ship is being delivered. Under SOLAS V Regulation 20, which record-keeping device must be installed to assist accident investigation?

  1. A course recorder
  2. A bridge navigational watch alarm system
  3. An electronic chart display and information system
  4. A simplified voyage data recorder Correct answer.

Explanation

Regulation 20 requires voyage data recorders, and permits a simplified voyage data recorder (S-VDR) for existing cargo ships in defined circumstances. The device is intended to provide information for accident investigation.

Question 31Safety of navigation: Chapter V equipment and carriage requirements

Under SOLAS V Regulation 27, what must the nautical charts and nautical publications carried on board be?

  1. Adequate and up to date for the intended voyage Correct answer.
  2. Printed on board by the master
  3. Approved by the flag State before each departure
  4. Corrected to the date of the last annual survey

Explanation

Regulation 27 requires nautical charts and nautical publications such as sailing directions, lists of lights and notices to mariners to be adequate and up to date for the intended voyage. The standard is voyage-based currency rather than alignment with a survey date.

Question 32Safety of navigation: Chapter V equipment and carriage requirements

SOLAS V Regulation 33 addresses which operational safety measure on passenger ships?

  1. Lifeboat launching drills
  2. Emergency instructions and muster lists Correct answer.
  3. Damage control drills
  4. Fire patrols

Explanation

Regulation 33 requires clear emergency instructions to be provided to passengers and a muster list to be displayed, so that passengers know their assembly station and duties are assigned. Lifeboat and damage control drills are covered under other regulations.

Question 33Safety of navigation: Chapter V equipment and carriage requirements

A 3,000 gross tonnage cargo ship on international voyages must carry a bridge navigational watch alarm system. Under SOLAS V Regulation 19, when must a BNWAS be in operation?

  1. Whenever the ship is at sea Correct answer.
  2. Only when the ship is in coastal waters
  3. Only when the ship is in restricted visibility
  4. Only during hours of darkness

Explanation

Regulation 19 requires the bridge navigational watch alarm system to be in operation whenever the ship is at sea. It is a watchkeeping integrity aid, so its operation is not limited to particular visibility or coastal conditions.

Question 34Safety of navigation: Chapter V equipment and carriage requirements

Under SOLAS V Regulation 19, which ships are required to have an echo sounder fitted?

  1. Ships of 3,000 gross tonnage and upwards
  2. All passenger ships regardless of size
  3. All ships of 300 gross tonnage and upwards
  4. Cargo ships of 500 gross tonnage and upwards Correct answer.

Explanation

Regulation 19 requires an echo sounder for cargo ships of 500 gross tonnage and upwards and for passenger ships of any size on international voyages. A 300 GT threshold applies to other equipment such as AIS, not the echo sounder.

Question 35Safety of navigation: Chapter V equipment and carriage requirements

A ship is fitted with ECDIS as the primary means of navigation. Under SOLAS V Regulation 19, what must be provided for the ECDIS installation?

  1. An adequate back-up arrangement Correct answer.
  2. A paper chart folio for every sea area
  3. A second independent gyro compass
  4. A dedicated radio operator

Explanation

Where ECDIS is used to meet the chart carriage requirement, Regulation 19 requires an adequate back-up arrangement to be provided. This may take a form permitted by the flag State, such as an independent ECDIS or an appropriate chart folio.

Question 36Safety of navigation: Chapter V equipment and carriage requirements

Under SOLAS V Regulation 19, a ship of 150 gross tonnage on an international voyage must be provided with which of the following?

  1. A gyro compass
  2. A daylight signalling lamp Correct answer.
  3. A speed and distance measuring device
  4. A rudder angle indicator

Explanation

Regulation 19 requires a daylight signalling lamp, together with a means of communication between the bridge and the emergency steering position, for ships of 150 gross tonnage and upwards. Gyro compass and speed and distance measuring device thresholds are set at 300 and 500 gross tonnage respectively for cargo ships.

Question 37Safety of navigation: Chapter V equipment and carriage requirements

What is the purpose of the bridge visibility requirements in SOLAS V Regulation 22?

  1. To set the minimum height of the bridge above the waterline
  2. To mandate the fitting of a conning position display
  3. To require a minimum number of bridge windows
  4. To ensure the field of vision from the navigating bridge meets defined criteria Correct answer.

Explanation

Regulation 22 sets out requirements for the field of vision from the navigation bridge, including forward and lateral sectors and blind sector limits, so that the officer of the watch can maintain an effective lookout. It does not prescribe a window count or a conning display.

Question 38Safety of navigation: Chapter V equipment and carriage requirements

Under SOLAS V Regulation 23, which ships must be fitted with a pilot ladder arrangement that complies with the regulation?

  1. Only passenger ships
  2. Only ships above 20,000 gross tonnage
  3. Ships engaged on voyages during which pilots are likely to be employed Correct answer.
  4. Only ships on regular pilotage routes

Explanation

Regulation 23 applies to ships engaged on voyages in the course of which pilots are likely to be employed, and requires pilot transfer arrangements to meet the specified standards. The obligation is triggered by the likelihood of pilot transfer, not by route type or size.

Question 39Safety of navigation: Chapter V equipment and carriage requirements

SOLAS V Regulation 26 requires a ship's steering gear to be tested before departure. How frequently must the steering gear test and drill be carried out?

  1. At least once every three months Correct answer.
  2. At least once every week
  3. At least once every month
  4. At least once every year

Explanation

Regulation 26 requires emergency steering drills to be carried out at least once every three months, and steering gear tests before departure. The quarterly interval is a specific interval that distinguishes this drill from weekly and monthly routines.

Question 40Safety of navigation: Chapter V equipment and carriage requirements

A ship's master intends to use a routeing system adopted by the Organization. Under SOLAS V Regulation 10, what is the master's obligation?

  1. The master may choose any route provided it is safe
  2. The master must use the routeing system in accordance with its rules Correct answer.
  3. The master must obtain a pilot before entering the system
  4. The master must notify the flag State before entering the system

Explanation

Regulation 10 requires routeing systems adopted by the Organization to be used in accordance with their rules, subject to defined exceptions where the ship's safety makes use impracticable. The obligation is to comply with the system rather than to notify or obtain a pilot.

Question 41Safety of navigation: Chapter V equipment and carriage requirements

Which ships must carry a long-range identification and tracking system under SOLAS V Regulation 19A?

  1. All ships of 300 gross tonnage and upwards
  2. Only ships on voyages exceeding 1,000 nautical miles
  3. Only tankers above 10,000 gross tonnage
  4. Passenger ships and cargo ships of 3,000 gross tonnage and upwards Correct answer.

Explanation

Regulation 19A applies LRIT to passenger ships, including high-speed craft, and to cargo ships of 3,000 gross tonnage and upwards. The higher tonnage threshold reflects the different policy purpose of LRIT compared with AIS.

Question 42Safety of navigation: Chapter V equipment and carriage requirements

Under SOLAS V Regulation 28, which records must the log book contain in relation to navigational incidents?

  1. Only entries relating to cargo damage
  2. Only entries countersigned by the flag State
  3. All details of any casualty or incident to which the ship is involved Correct answer.
  4. Only entries relating to machinery failure

Explanation

Regulation 28 requires the log book to record all details of any casualty or incident to which the ship is involved, as well as the daily position. The record supports subsequent investigation and reporting obligations.

Question 43Safety of navigation: Chapter V equipment and carriage requirements

A ship of 400 gross tonnage is fitted with a magnetic compass. Under SOLAS V Regulation 19, what additional provision must be made for transmitting heading information to the emergency steering position?

  1. A spare magnetic compass
  2. A rate of turn indicator
  3. A second steering gear motor
  4. A means of communication between the bridge and the emergency steering position Correct answer.

Explanation

Regulation 19 requires ships of 150 gross tonnage and upwards to have a means of communication between the bridge and the emergency steering position. This supports control of the ship if the bridge steering position is lost.

Question 44Safety of navigation: Chapter V equipment and carriage requirements

Under SOLAS V Regulation 19, which ships must be fitted with a rate of turn indicator?

  1. All ships of 300 gross tonnage and upwards
  2. Ships of 500 gross tonnage and upwards
  3. Ships of 3,000 gross tonnage and upwards Correct answer.
  4. Ships of 50,000 gross tonnage and upwards

Explanation

Regulation 19 requires a rate of turn indicator for ships of 3,000 gross tonnage and upwards, reflecting the manoeuvring information needs of larger vessels. Lower tonnage thresholds in the same regulation apply to other items such as AIS and the speed and distance measuring device.

Question 45Safety of navigation: Chapter V equipment and carriage requirements

A new cargo ship of 2,000 gross tonnage is to be fitted with ECDIS. Under SOLAS V Regulation 19, what must the ECDIS be capable of displaying?

  1. Only weather overlay information
  2. Only privately produced vector charts
  3. Only paper chart scans
  4. Electronic navigational charts and, where permitted, raster chart data Correct answer.

Explanation

The ECDIS performance standard requires the system to display electronic navigational charts as its primary chart data and permits raster chart display where authorised. Privately produced vector charts and weather overlays do not satisfy the chart carriage requirement on their own.

Question 46Safety of navigation: Chapter V equipment and carriage requirements

Under SOLAS V Regulation 31, what is the required frequency for the testing of the ship's automatic identification system by the master?

  1. Daily Correct answer.
  2. Annually
  3. Monthly
  4. Weekly

Explanation

Regulation 31 requires the master of a ship fitted with AIS to ensure the AIS is maintained in effective operating condition, and the associated guidance calls for daily checks of the information transmitted. Regular daily verification supports the reliability of the data received by other ships and shore stations.

Question 47Safety of navigation: Chapter V equipment and carriage requirements

A ship is not required to carry a voyage data recorder under SOLAS V Regulation 20. Which statement correctly describes the regulation's treatment of such a ship?

  1. A course recorder may be substituted for a VDR without flag State approval
  2. No VDR or S-VDR is required, and the ship is exempt from all recording obligations
  3. An S-VDR may be fitted where a VDR is not required and the flag State permits it Correct answer.
  4. A VDR must still be fitted if the ship exceeds 500 gross tonnage

Explanation

Regulation 20 provides for a simplified voyage data recorder to be fitted where a full VDR is not required, subject to the conditions set by the Administration. This preserves an accident investigation record without imposing the full VDR standard on all ships.

Question 48Safety of navigation: Chapter V equipment and carriage requirements

Under SOLAS V Regulation 14, what must be arranged for the safe manning of a ship?

  1. A watch schedule approved by the master's employer
  2. A crew list approved by the port State at each call
  3. A minimum number of certificated officers fixed by the ship's classification society
  4. A document of minimum safe manning issued by the Administration Correct answer.

Explanation

Regulation 14 requires ships to be manned with a sufficient number of qualified personnel and to hold a document of minimum safe manning issued by the Administration. The document evidences the flag State's determination of the safe manning level.

Question 49Safety of navigation: Chapter V equipment and carriage requirements

A ship's navigational equipment includes a speed and distance measuring device. Under SOLAS V Regulation 19, which ships are required to carry it?

  1. Cargo ships of 300 gross tonnage and upwards
  2. All ships of 1,600 gross tonnage and upwards
  3. Cargo ships of 500 gross tonnage and upwards Correct answer.
  4. Only ships of 10,000 gross tonnage and upwards

Explanation

Regulation 19 requires a speed and distance measuring device for cargo ships of 500 gross tonnage and upwards and for passenger ships of any size. The 300 GT figure applies to other items such as AIS, and the higher figures do not correspond to this requirement.

Question 50Safety of navigation: Chapter V equipment and carriage requirements

Under SOLAS Chapter V, a ship's navigational equipment must be type-approved and installed so that it does not interfere with other equipment. Which statement best describes the Regulation 18 requirement for approval of navigational systems and equipment fitted on or after 1 July 2002?

  1. They must be approved only if the ship is a passenger ship; cargo ships are exempt from approval requirements.
  2. They must be approved by the equipment manufacturer's national government rather than the flag State.
  3. They must be type-approved by the Administration in accordance with the relevant performance standards adopted by the Organization. Correct answer.
  4. They must be approved by the shipyard's classification society alone, without reference to the flag Administration.

Explanation

SOLAS V Regulation 18 requires that navigational systems and equipment installed on or after 1 July 2002 be type-approved by the Administration in accordance with the performance standards adopted by the Organization. The Administration may delegate testing to recognized bodies, but the approval authority and the applicable IMO standards remain the governing benchmark. Approval by a manufacturer or builder alone does not satisfy the regulation.
