Question 1

Your vessel has grounded on an uncharted shoal in daylight, moderate weather. The vessel is not taking water. As master, describe your immediate and subsequent actions.

Accepted Answer

Immediate: mark time and position; stop engines; sound the general alarm and muster crew; assess the situation (is the vessel taking water? Is there a risk of broaching?); test bilges in all spaces including cargo holds; do NOT attempt to refloat immediately without assessing the risk of structural damage from movement. Subsequent: check tidal state and predictions (is it ebbing or flooding? What is the tidal range available?); carry out a 360-degree sounding survey around the vessel; check structural integrity (hull stress, tank levels); report to MRCC, flag state, company/DPA. Ensure vessel is displaying NUC signals (two black balls by day, two red lights at night). Consider requesting tug assistance. Do not discharge cargo or fuel to lighten ship without specialist advice. Grounding response is one of the most tested Master Unlimited emergency scenarios. Key decision points: (1) refloating attempt immediately may worsen structural damage if the vessel is hard aground — delay until the tidal assessment confirms the approach; (2) as tide ebbs the vessel may list or stress further — cargo shifting is a risk; (3) structural damage assessment before refloating is critical — if the hull is breached, refloating into deeper water may cause sinking; (4) under SOLAS V Reg 31, grounding must be reported to MRCC; under MARPOL, any resulting pollution must also be reported; (5) NUC (Not Under Command) signals must be displayed as the vessel cannot manoeuvre. Under UK law (MAIB Regulations 2012), a grounding is a "serious casualty" requiring reporting to MAIB. The master should also activate the SOPEP in case of any fuel or oil discharge. At Master Unlimited level, the examiner expects the candidate to demonstrate methodical prioritisation under pressure rather than reactive decision-making.

Question 2

Your company operations manager calls and says "you must sail tonight — the charterer will fine us $50,000 if we miss the tide." You believe the weather makes departure unsafe. Your examiner asks: "What is your legal and professional position?" Give a Master-level answer.

Accepted Answer

The master has absolute overriding authority for the safety of the vessel, crew, cargo, and the marine environment under ISM Code Regulation 5 and SOLAS IV/4. Commercial pressures — however significant financially — cannot override this authority. The master should document the decision in the Official Log with reasons, inform the DPA, and require written authority from the company to sail if they persist. The company cannot lawfully discipline a master for a genuine safety decision. A master who sails in unsafe conditions on commercial instruction shares culpability for any resulting casualty. ISM Code Regulation 5 is the cornerstone of master's authority: "The Company shall establish in the SMS that the master of the Company's ship has the overriding authority and the responsibility to make decisions with respect to safety and pollution prevention and to request the Company's assistance as may be necessary." This is reinforced by SOLAS IV/4 and MLC 2006 Regulation 2.7 (manning and hours of rest). Multiple MAIB investigation reports identify commercial pressure as a latent contributing factor to accidents — the master's role is to be the final safety barrier. In UK law, the master has a common law duty of care to the crew that overrides any contractual obligation to the charterer. Documenting the decision in the Official Log protects the master legally. If the company persists, requiring written authority is both professionally appropriate and creates a clear record of where the decision was made.

Question 3

You receive a distress signal from a vessel 80nm away. Your ETA to the casualty is approximately 6 hours. Your vessel is fully loaded with time-critical cargo. Describe your legal obligations and the factors you must consider.

Accepted Answer

SOLAS Chapter V Regulation 33: the master of a ship at sea which is in a position to render assistance on receiving information from any source that persons are in distress at sea is bound to proceed with all speed to their assistance. This obligation is absolute — there is no commercial exemption. You must proceed at best speed, inform the cargo interests and charterer, and advise the MRCC of your ETA. The obligation is released only if: you receive information that assistance is no longer necessary; another vessel is better placed and the RCC releases you; proceeding would seriously endanger the ship or persons on board; or the distress is being handled by another vessel or shore authority who has released you. Failing to render assistance without lawful reason is a criminal offence in most jurisdictions. SOLAS V Reg 33 and UNCLOS Article 98 establish the master's duty to render assistance as a peremptory norm of international maritime law — it cannot be contracted away. The International Convention on Maritime Search and Rescue 1979 also imposes obligations on states to coordinate SAR. The releasing conditions listed are precise: the MRCC (RCC) must formally release the master from the obligation — the master cannot unilaterally decide assistance is no longer required. P&I Clubs provide clear guidance: proceed to render assistance, advise charterers, document everything, and the resulting costs (deviation, cargo damage, delay) are typically covered as General Average or covered by P&I under the duty-to-assist obligation. Criminal prosecution for failure to render assistance has occurred in multiple jurisdictions (UK MSA 1995 s.93; US 46 USC 2304). At Master Unlimited level, this is a fundamental command examination question.
