Three crew members are hospitalised in port with food poisoning. Your Safe Manning Document requires a minimum of 14 crew. You now have 11. Can you sail?

A. UNDER-MANNING — MASTER'S DECISION: Safe Manning Document (SMD): issued by the flag state (MCA for UK vessels) specifying the minimum number of officers and ratings required for the vessel to operate safely. It is a STATUTORY DOCUMENT — not a recommendation. ASSESSMENT: 14 required, 11 available — 3 below minimum safe manning. Can you sail? ANSWER: NOT WITHOUT FLAG STATE APPROVAL. PROCEDURE: (1) NOTIFY COMPANY AND FLAG STATE IMMEDIATELY: the under-manning situation must be reported to the shipowner and the MCA (or flag state). Request an exemption or dispensation if required; (2) MCA DISPENSATION: the MCA can issue a short-term dispensation (under SOLAS V/14) permitting the vessel to sail with temporary reduced manning IF: (a) the vessel's voyage is assessed as manageable with 11 crew; (b) additional watch-keeping arrangements are made; (c) the vessel proceeds to the next port where replacement crew can board; (3) RISK ASSESSMENT: if a dispensation is considered — the master must assess: can safe watches be maintained with 11 crew? (STCW rest hours must still be met.) Are all critical safety functions covered (navigation, firefighting, emergency response)? (4) DO NOT SAIL IF UNSAFE: the master has the overriding authority to refuse to proceed if the manning level makes the voyage unsafe — regardless of commercial pressure; (5) REPLACE CREW: contact the manning agent to arrange emergency replacement crew — this is the fastest solution; (6) PSC: if the vessel arrives at next port with manning below SMD without dispensation — immediate detention.

B. The Safe Manning Document is a guideline. If 11 of 14 crew are available and all key roles are covered, the vessel may sail without any further authority.

C. In an emergency, the vessel can sail with reduced manning as long as the master personally covers the deficient watches. The master's unlimited certificate allows them to perform any role.

D. The three hospitalised crew members must be signed off and replaced within 24 hours. The shipping company is liable for all costs and the vessel waits in port until fully manned.

A. FLAG STATE JURISDICTION — MASTER'S OVERVIEW: Under UNCLOS Article 91, every vessel must be registered under a flag state. The flag state has jurisdiction over the vessel on the high seas and is responsible for ensuring the vessel complies with international conventions. PRINCIPLE: a vessel on the high seas is subject ONLY to the flag state's jurisdiction (with exceptions for piracy, slave trade, stateless vessels, and in some cases drug trafficking). Port states (under UNCLOS Article 218) have additional jurisdiction in port. UK FLAG STATE OBLIGATIONS (MCA): (1) UK-flagged vessels must comply with ALL UK statutory instruments implementing international conventions; (2) The MCA issues the statutory certificates (LL, SOLAS, IOPP, etc.) directly or through Recognised Organisations (ROs) such as Lloyd's Register or DNV; (3) MCA conducts flag state inspections — different from PSC inspections; (4) STCW: UK officers must hold UK CoC (issued by MCA). The MCA implements the STCW Convention through the Merchant Shipping (Standards of Training, Certification and Watchkeeping) Regulations 2015; (5) SEAFARER EMPLOYMENT AGREEMENT (SEA): MCA requires UK vessels to have MLC-compliant SEAs; (6) VESSEL REGISTRATION: UK registry is maintained by MCA Ship Register. The Master's name may be entered on the register for vessels over a certain GT; (7) ISM: the MCA issues the Document of Compliance (DOC) to UK shipping companies and the SMC to UK vessels. OPEN REGISTERS: Flag of Convenience (FoC) states (Panama, Liberia, Marshall Islands) offer registration with less regulatory scrutiny. They are still obligated under SOLAS/MARPOL as signatories.

B. Once a vessel is registered under a flag, the flag state has no further obligations. All safety obligations are transferred to the vessel's operator.

C. Port state control supersedes flag state jurisdiction. A vessel in port is subject only to the port state's laws and the flag state has no authority over the vessel in a foreign port.

D. The master of a UK-flagged vessel is employed by MCA. The MCA is responsible for paying crew and maintaining the vessel on behalf of the UK government.

A. SOLAS SURVEY SCHEDULE — MASTER'S KNOWLEDGE: SOLAS Chapter I Regulation 9 sets the survey requirements. KEY SURVEYS: (1) INITIAL SURVEY: before the vessel is put into service — before certificates are first issued. Comprehensive survey of structure, machinery, equipment; (2) RENEWAL SURVEY: at 5-year intervals. Full survey to renew all statutory certificates. Vessels must be drydocked for the hull survey; (3) ANNUAL SURVEY: each year (between 3 months before and 3 months after the anniversary date of the certificate). Confirmed that conditions remain satisfactory. The annual survey endorses the certificate for the next year; (4) INTERMEDIATE SURVEY: at the second or third annual survey (within 6 months of the halfway point of the 5-year certificate). A more detailed inspection between renewal surveys; (5) PERIODICAL SURVEY: for specific equipment (e.g., safety equipment) at set intervals — lifeboats 5 years (comprehensive) and annually (operational); (6) DRYDOCK: hull inspection below the waterline — every 2.5 years (5-year intervals with intermediate drydock at 2.5 years). LOAD LINE SURVEY: similar 5-year renewal with annual surveys. MASTER'S ROLE: (1) MAINTAIN THE SURVEY SCHEDULE: track all survey due dates (annual, intermediate, renewal). Give the DPA/company advance notice (typically 3-6 months); (2) PREPARE THE VESSEL: ensure the vessel is in survey-ready condition at all times — equipment operational, certificates up to date, crew trained; (3) COOPERATE WITH SURVEYOR: accompany the surveyor, produce all documents, demonstrate equipment; (4) DEFICIENCIES: immediately report to company any deficiency that may affect the survey outcome.

B. SOLAS certificates are permanent once issued. They do not require renewal surveys — only if the vessel undergoes major modifications.

C. The classification society is responsible for all SOLAS surveys. The master has no role in survey preparation — this is entirely a technical matter for the chief engineer.

D. Annual surveys are only required for passenger vessels. Cargo ships only need the 5-year renewal survey.
