Q: Your examiner asks: "What does a Chief Mate < 3000 GT certificate permit, and what are the practical limitations compared to a Chief Mate Unlimited?"

Chief Mate < 3000 GT certificate (STCW Regulation II/2 — Chief Mate < 3000 GT): permits serving as Chief Mate on ships less than 3000 GT — this includes many coastal traders, short-sea vessels, offshore support vessels, large passenger ferries, and survey vessels. Limitations compared to Unlimited: (1) Cannot serve as Chief Mate on vessels of 3000 GT or above; (2) May be geographically unrestricted — depends on individual endorsement (CM 3000 GT may have near-coastal or unlimited geographic endorsement depending on training and flag state); (3) The competency standard assessed covers the same management-level functions as unlimited but with parameters appropriate to smaller vessel operations (e.g., cargo types, stability calculations, crew size); (4) The certificate holder can progress to CM Unlimited and Master Unlimited by completing additional sea service and passing further oral examinations. STCW Chapter II separates certification by vessel size and geographic scope: Regulation II/1 covers OOW on ships ≥500 GT; Regulation II/2 covers Chief Mate and Master; Regulation II/3 covers OOW, Chief Mate and Master on ships

Question 1

You are Chief Mate on a short-sea vessel. A new rating joins ship and presents a basic safety training (BST) certificate dated 6 years ago. The rating has not served on a ship for 4 years. Can this rating stand watch?

Accepted Answer

The rating cannot stand watch without current STCW Basic Safety Training. STCW Regulation VI/1 and Code A-VI/1: Basic Safety Training (fire prevention/firefighting, personal survival techniques, first aid, personal safety and social responsibility) must be completed within the 5 years prior to service. A BST certificate dated 6 years ago with a 4-year sea service gap exceeds the 5-year recency requirement. Action as Chief Mate: (1) The rating is not compliant — notify the master immediately; (2) The company must arrange a BST refresher course before the rating can stand watch or perform safety duties; (3) If the vessel cannot depart with the required manning, the sailing date may be affected; (4) Note the discrepancy in the crew documentation and report to the company; (5) The rating may assist with non-safety-critical duties while refresher is arranged if the master permits, but cannot be counted against the Safe Manning Certificate. STCW revalidation requirements are a Chief Mate manning management responsibility. STCW 2010 Manila Amendments (applicable from 1 January 2012): introduced a 5-year refresher requirement for most STCW certificates and competencies. Basic Safety Training (STCW A-VI/1) refresher: candidates who have not maintained approved seagoing service and not undertaken refresher training within the last 5 years must complete refresher or demonstrate competency before being issued a new STCW endorsement. The MCA issues STCW certificates with 5-year validity — but the BST standard also has a practical revalidation requirement. Safe Manning Certificate: the vessel's SMC specifies the minimum number and qualifications of crew required for safe operation. If a crew member cannot be counted toward the SMC requirements (due to expired or non-compliant certificates), the vessel may not legally sail. Chief Mate responsibility: checking that crew joining the vessel hold valid and appropriate STCW certificates before departure is a management-level duty. The company's crewing department should have verified this — but the Chief Mate is the last line of defence on board.

Question 2

Your examiner asks: "What does a Chief Mate < 3000 GT certificate permit, and what are the practical limitations compared to a Chief Mate Unlimited?"

Accepted Answer

Chief Mate < 3000 GT certificate (STCW Regulation II/2 — Chief Mate < 3000 GT): permits serving as Chief Mate on ships less than 3000 GT — this includes many coastal traders, short-sea vessels, offshore support vessels, large passenger ferries, and survey vessels. Limitations compared to Unlimited: (1) Cannot serve as Chief Mate on vessels of 3000 GT or above; (2) May be geographically unrestricted — depends on individual endorsement (CM 3000 GT may have near-coastal or unlimited geographic endorsement depending on training and flag state); (3) The competency standard assessed covers the same management-level functions as unlimited but with parameters appropriate to smaller vessel operations (e.g., cargo types, stability calculations, crew size); (4) The certificate holder can progress to CM Unlimited and Master Unlimited by completing additional sea service and passing further oral examinations. STCW Chapter II separates certification by vessel size and geographic scope: Regulation II/1 covers OOW on ships ≥500 GT; Regulation II/2 covers Chief Mate and Master; Regulation II/3 covers OOW, Chief Mate and Master on ships

Question 3

As Chief Mate on a 2,200 GT short-sea general cargo vessel, you are asked to plan a winter coastal passage from Aberdeen to Rotterdam. Your examiner asks how you approach the appraisal and planning stages.

Accepted Answer

SOLAS V Reg 34 Appraisal stage: gather: (1) Weather forecast — North Sea winter weather from Met Office and NAVTEX: likely depressions every 3-5 days, Force 8-9 common, sea state 5-7m in the northern North Sea; (2) Tidal information — tidal streams in the North Sea can reach 2-3 knots off headlands; factor into ETAs and berth windows; (3) Notices to Mariners — update charts; check for new wrecks, hazards, or Traffic Separation Schemes modifications; (4) Ship's condition — cargo distribution, stability at departure, GM, SF/BM; (5) Pilot/port information — check Rotterdam Waterway guidance, Maas approach, VTS; (6) NAVAREA warnings and current MSI broadcasts. Planning stage: (1) Lay off the track on charts — clearances from Humber, Dutch Frisian Islands, Traffic Separation Schemes; (2) Plan departure for fair weather window if possible; (3) Identify contingency ports (Bremerhaven, IJmuiden) if weather deteriorates; (4) Calculate distance, speed, ETA with weather routing consideration. SOLAS V Regulation 34 applies to all ships on all voyages — there is no exemption for coastal vessels or short-sea traders. The four-stage voyage planning process (Appraisal, Planning, Execution, Monitoring) is required at management level and the Chief Mate's role in the process is examined at CM level. North Sea winter conditions: this is a specific scenario that tests geographic knowledge — North Sea winter has a high frequency of Atlantic depressions, particularly October-February. Force 8-9 gale conditions are common for periods of 12-24 hours. A 2,200 GT coastal vessel in these conditions: heavy rolling, deck cargo risk, sea spray and structural stress. The passage from Aberdeen to Rotterdam involves passing through TSS schemes (Outer Hebrides, North Sea traffic separation). Contingency ports demonstrate planning for failure: if weather deteriorates mid-passage, the Chief Mate should have pre-identified ports of refuge and their approach conditions. CM level candidates must demonstrate awareness of the full SOLAS V/34 framework and apply it with geographic specificity.
