NIMASA STCW MSA flashcards

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Rule 5 Lookout

Every vessel must at all times maintain a proper lookout by sight and hearing as well as by all available means appropriate to the circumstances, to make a full appraisal of the situation and risk of collision.

Rule 19 Restricted Visibility

In restricted visibility the stand-on/give-way relationship does not apply; every vessel proceeds at a safe speed, and a close-quarters situation developing requires action to avoid collision.

Passage Plan Stages

Appraisal, planning, execution and monitoring. The plan is berth to berth and includes no-go areas, abort points, contingency anchorages and wheel-over positions marked on charts.

Safe Speed Factors

Visibility, traffic density, manoeuvrability, background lights, wind, sea and current state, draught relative to depth, and radar performance all determine a safe speed; no fixed figure is prescribed.

Muster List

A posted document assigning each crew member a station and duty for fire, abandon ship, man overboard and pollution response. It is updated after crew changes and before sailing.

Abandon Ship Order

Only the master gives the order to abandon ship. Crew don lifejackets and immersion suits, board lifeboats on the lee side and hold the painter until clear of the vessel.

Fire Triangle

Fuel, oxygen and heat. Extinguishing removes at least one leg. CO2 displaces oxygen, foam blankets hydrocarbon fires, dry powder is general purpose, and water cools.

Enclosed Space Entry

Requires a permit, atmosphere testing for oxygen, hydrocarbons, CO and H2S, continuous ventilation, a standby man at the entrance, and rescue equipment positioned before entry.

UMS Watchkeeping

Unattended machinery space operation requires tested alarms and safety devices, an active dead-man alarm, and the duty engineer within the required call-out time; periodic rounds continue.

Oily Water Separator Limit

Under MARPOL Annex I, discharge through the oily water separator is permitted only when the oil content is 15 ppm or less, the 15 ppm alarm works, and the ship is proceeding en route.

Engine Room Handover

The relieving engineer receives machinery condition, running hours, fuel, water and lube oil levels, bilge state, alarms and ongoing repairs, then signs the log to accept the watch.

Emergency Generator Test

The emergency generator must start and take load automatically on main power failure; it is tested weekly and the test recorded in the engine room log.

MARPOL Annexes

Annex I oil, II noxious liquid substances, III harmful packaged substances, IV sewage, V garbage, and VI air pollution, which includes EEDI, EEXI and carbon intensity ratings.

STCW Rest Hours

Minimum 10 hours of rest in any 24-hour period and 77 hours in any 7-day period; rest may be split into no more than two periods, one of at least 6 hours.

UNCLOS Maritime Zones

Internal waters, territorial sea to 12 nm, contiguous zone to 24 nm, exclusive economic zone to 200 nm, and the high seas beyond. Innocent passage applies in the territorial sea.

Port State Control Detention

A PSCO may detain a ship for deficiencies that make it unseaworthy; the detention is reported to the flag State and to IMO, and a follow-up inspection is required before release.

Metacentric Height GM

GM equals KM minus KG. Positive GM gives stable equilibrium, negative GM gives an unstable or lolling ship, and the area under the GZ curve represents righting energy.

Free Surface Correction

FSC equals i times density divided by displacement, where i is the second moment of area of the free surface. Longitudinal subdivision reduces i and therefore the loss of GM.

Load Line Marks

The deck line and summer load line set the assigned freeboard; seasonal marks for tropical, winter, winter North Atlantic and the fresh water allowance are measured from the deck line.

Cargo Liquefaction Risk

Group A bulk cargoes such as iron ore fines and nickel ore can liquefy if moisture exceeds the transportable moisture limit, causing a free surface and loss of stability.

Annex I Discharge Rule

Outside special areas, oily water may be discharged only when the ship is proceeding en route, oil content is 15 ppm or less, and approved oily-water separating equipment is in use.

Annex VI Sulphur Limits

The global sulphur limit is 0.50% m/m and the limit in emission control areas is 0.10% m/m. Compliance is by compliant fuel, an approved scrubber, or alternative fuel.

Annex V Garbage Rule

Plastics may never be discharged. Food waste may be discharged outside 12 nm, or outside 3 nm if comminuted; the garbage record book and placards are required.

Ballast Water D-2 Standard

The D-2 standard limits viable organisms in discharged ballast water; ships must hold an approved ballast water management plan and record all operations in the ballast water record book.

ISPS Security Levels

Level 1 normal, Level 2 heightened and Level 3 exceptional. The flag State or port State sets the level, and the Ship Security Plan prescribes the additional measures for each.

Ship Security Alert System

A covert alarm transmitting to the Administration without sounding on board. It must be tested per flag State requirements and each test recorded in the ship's records.

Declaration of Security

An agreement between ship and port facility on security measures, required when the ship's security level is higher than the port's or when the port State requires it.

GMDSS Sea Areas

A1 within VHF DSC coverage, A2 within MF DSC coverage, A3 within Inmarsat coverage, and A4 outside A1 to A3, where HF is required for distress and safety communications.

DSC Distress Alert

Sent on VHF Ch 70 or MF 2187.5 kHz with the MMSI, nature of distress, position and time, and followed by a distress message on the associated radiotelephone frequency.

NAVTEX Frequencies

International broadcasts on 518 kHz, national broadcasts on 490 kHz, and some services on 4209.5 kHz, carrying navigational and meteorological warnings and SAR information.

CPR Compression Ratio

For adults, 30 chest compressions followed by 2 rescue breaths; the AED is applied as soon as available and the casualty is reassessed after each cycle.

Hypothermia First Aid

Handle the casualty gently, remove wet clothing, insulate and rewarm slowly. Do not give alcohol or rub the limbs; immersion in cold water causes rapid heat loss.
