Your vessel has successfully controlled a fire in the engine room. One crew member was treated for smoke inhalation. Describe the master's post-emergency reporting and documentation obligations.

A. POST-EMERGENCY REPORTING — MASTER'S OBLIGATIONS: IMMEDIATE INTERNAL REPORTING: (1) Notify company DPA with a full situation report; (2) Notify P&I Club (potential injury claim); (3) Update the MRCC: if a Mayday or PAN PAN was declared, contact MRCC to declare the emergency is terminated. OFFICIAL LOG ENTRIES: (1) Full narrative of the incident: time of first alarm, actions taken, fire control measures, who was involved, time fire was declared extinguished; (2) Crew injury: name, nature of injury, treatment given, current status; (3) Damage found: location, extent, systems affected. ACCIDENT AND INCIDENT REPORTING: (a) UK MCA: MAIB (Marine Accident Investigation Branch) must be notified of any serious marine accident under the Merchant Shipping (Accident Reporting and Investigation) Regulations 2012. Engine room fire = serious accident. Report via online portal within the notification period; (b) Flag state if non-UK: flag state Marine Accident Investigation authority notified as per their regulations; (c) ISM NON-CONFORMITY: raise an internal NCR (Non-Conformance Report) under the SMS if the incident reveals a system deficiency; (d) Insurance notification: hull and machinery insurers notified of fire damage. CLASSIFICATION SOCIETY: fire damage to structural members, electrical systems, or safety equipment must be assessed by a class surveyor before the affected systems are returned to service. Crew injury: MSF 1650 / Accident Report submitted to flag state.

B. Post-emergency reporting only applies if there was a fatality. Successfully controlled incidents with no fatalities do not require regulatory notification.

C. Complete the onboard fire incident report and file it. External reporting is only required if the vessel calls at a UK port — overseas incidents are reported to the flag state by the owner, not the master.

D. Verbal notification to the company is sufficient. Written reports and log entries are only required for incidents that result in vessel damage exceeding USD 100,000.

A. ABANDON SHIP DECISION — COMMAND AUTHORITY AND FRAMEWORK: THE MASTER'S AUTHORITY: SOLAS Chapter III and the ISM Code place the abandon ship decision exclusively with the master. The company can advise but cannot override the master's decision on abandonment — SOLAS V/34.1 confirms the master's ultimate authority for safety. TIMING CONSIDERATIONS: abandon ship is a last resort — the following criteria support the decision: (1) Fire cannot be controlled or contained and is spreading; (2) The vessel's structural integrity is threatened (fire in hold = risk of structural steel softening); (3) The fire is approaching fuel tanks, cargo spaces or gas lines; (4) Crew casualties are occurring or the crew cannot fight the fire safely; (5) The vessel is listing or there are signs of progressive flooding; (6) MRCC has been informed and rescue assets are en route. DECISION PROCESS: (1) Assess the fire situation honestly — is containment possible? (2) Contact MRCC: transmit Mayday if not already done, give position, vessel size, crew number, nature of emergency; (3) Prepare lifeboats and liferafts — muster crew at stations (this is preparation, not abandonment); (4) Give the order only when the vessel is no longer safe to remain on board; (5) THE SIGNAL: 7 short blasts + 1 long blast on the ship's whistle and alarm system; (6) Confirm crew muster complete before ordering "abandon ship." The sequence: Mayday → muster → prepare boats → last-resort order.

B. Abandon ship as soon as the fire cannot be controlled in the first 10 minutes. Early evacuation is always safer than remaining on a burning vessel.

C. Contact the company DPA and wait for authorisation before ordering abandon ship. The master cannot make the abandon ship decision independently without company approval.

D. Order all crew to liferafts immediately and do not attempt to lower the lifeboats in a fire situation — lifeboat fuel tanks may ignite.

A. CO₂ TOTAL FLOODING — COMMAND DECISION PROCESS: WHY CARE IS REQUIRED: CO₂ at fire-extinguishing concentrations (34%+ in air) is instantly fatal to any person in the space. Premature or incorrect CO₂ release has killed crew members. The decision must be deliberate and methodical. DECISION PROCESS: (1) CONFIRM FIRE: (a) Is this a genuine fire or a detector fault/false alarm? Visual confirmation via CCTV or access port; (b) Smoke odour in adjoining spaces; (c) Temperature alarms; (2) CONFIRM SPACE IS EVACUATED: (a) Account for ALL persons who may be in the engine room — use the muster list; (b) Any engineer on watch must be accounted for; (c) Check all access points and adjoining spaces; (3) CLOSE AIR SUPPLY: shut all ventilation fans, air intakes, and dampers to the engine room — CO₂ is only effective in a sealed space; (4) STOP FUEL OIL SUPPLY to reduce fire fuel load; (5) SOUND CO₂ ALARM (typically a horn or klaxon in the space) for a mandatory warning period before release (SOLAS requirement); (6) CONFIRM RELEASE WITH CHIEF ENGINEER: the decision to release should be a coordinated command decision; (7) RELEASE CO₂: activate from the CO₂ release station; (8) DO NOT ENTER for minimum 30 minutes after release — CO₂ dissipates but atmosphere must be tested before re-entry.

B. Activate the CO₂ system immediately when the detector alarms — speed is critical and any delay risks fire spread. Pre-release checks slow down the response.

C. CO₂ systems activate automatically when the smoke detector reaches a threshold — manual activation by the master is not required and the master should monitor rather than intervene.

D. Use the portable CO₂ extinguishers first. The fixed CO₂ total flooding system should only be used as an absolute last resort when all other methods have failed.
