Chief Mate CoC study guide
Chief Mate CoC · Work through your exam, one topic at a time.
The Chief Mate Certificate of Competency is the credential that qualifies a deck officer to serve as chief officer on seagoing ships, and it is normally the step between Officer of the Watch and Master. Candidates are typically experienced watchkeeping officers who have completed the required sea service and an approved programme of education and training. The Chief Mate CoC study guide has 10 sections and about 4,895 words.
01Navigation and Passage Planning
The Navigation and Passage Planning domain examines whether you can take a ship from berth to berth on a route that is planned, monitored and auditable, and defend each decision in that plan under examination pressure. Administrations expect the IMO framework in Resolution A.893(21) to be visible in your answers and in the ship's actual plan.
497 words, about 2 min02Ship Stability and Cargo Operations
Ship Stability and Cargo Operations covers the intact and damage stability calculations you sign off as chief mate, plus the cargo knowledge that keeps a laden ship inside those limits. Examiners test numbers, and they test whether you know which limit governs when two are close together.
458 words, about 2 min03Meteorology and Oceanography
Meteorology and Oceanography examines whether you can read a synoptic chart, anticipate weather before it arrives, and manoeuvre to avoid the worst of it - including the one system that can sink a ship in hours. Wind follows the pressure gradient, deflected to the right in the Northern Hemisphere and to the left in the Southern.
505 words, about 3 min04Ship Construction and Damage Control
Ship Construction and Damage Control tests your grip on the structure that carries the loads and on what happens to strength and stability once water is inside. Expect hull girder bending, subdivision and damage stability in the same question.
451 words, about 2 min05Maritime Law
Maritime Law tests the contractual and liability framework behind everyday shipboard decisions: what you sign, what you may refuse, and who pays when something goes wrong. Expect bills of lading, charterparties, laytime and demurrage, general average, salvage, limitation and pollution liability.
397 words, about 2 min06Conventions and Codes
Conventions and Codes tests the treaties behind the certificates in the ship's file: which instrument applies, at what tonnage, for how long, and what happens when one lapses. The umbrella safety convention, now fifteen chapters.
464 words, about 2 min07Watchkeeping and Collision Regulations
Watchkeeping and Collision Regulations is the highest-frequency area in chief mate papers: the COLREGs applied to real geometry, plus the STCW standard for watch composition, rest and fitness for duty. Rule 5: look-out by sight and hearing and by all available means, including radar.
464 words, about 2 min08Emergency Response and Safety Management
Emergency Response and Safety Management tests whether the ship's response is planned, drilled and recorded, and whether you can give a clear, correctly sequenced answer under pressure. The SMS must identify potential emergency situations, provide response procedures, and exercise them.
408 words, about 2 min09Marine Engineering and Systems
Marine Engineering and Systems covers what a deck officer must genuinely understand about propulsion, steering and auxiliary plant - enough to run the ship safely and to question a decision politely but firmly. Slow-speed two-stroke diesels drive the propeller directly; medium-speed four-strokes work through reduction gearing.
427 words, about 2 min10Leadership, Management and Human Element
Leadership, Management and Human Element tests judgement: how you get a bridge team to speak up, how you handle fatigue and conflict, and how you build a culture where the same error does not happen twice. Bridge and engine resource management rest on situational awareness, workload management, communication and decision-making.
