Eight Hours to Sailing: Sorting Real Deficiencies from Housekeeping
MV Pacific Vine, a 13-year-old container ship, sails in eight hours. The safety officer's handover notes show: the port lifeboat was last launched with its crew and manoeuvred 3 months and 20 days ago; the free-fall lifeboat aft was last launched 7 months ago, with no simulated launch recorded; the rescue boat was launched 4 months ago, although its engine was run on the quay two weeks ago; six of the 24 immersion suits were opened during a training session and left unrepacked in a locker; the disposable hydrostatic release unit on the 16-person liferaft carries an expiry date three weeks away; the lifeboat release gear was last thoroughly examined 4 years and 11 months ago; one davit limit switch has been bypassed with a wire for the past three port calls; and the five-yearly dynamic brake test certificate is on file. A follow-up port state control visit is expected.
1. Sort these items into those that must be cleared before departure and those that can be scheduled, and justify each classification.

Clear before departure - safety-critical, no compensating measure:
- The bypassed davit limit switch. A wire bypass defeats the interlock that stops the davit being over-hoisted or over-lowered. It can allow the davit arm to be driven past its designed travel, shock-loading the structure and the falls, and it removes a protection during precisely the evolution when someone is underneath. Restore the circuit and prove it operates. If the correct part cannot be obtained in eight hours, the boat is out of service and the defect is documented - that is a better outcome than an unrepaired interlock.
- The unrepacked immersion suits. Opened suits are not serviceable until they have been checked and repacked per the maker's instructions; a suit that has been lying open may be creased, damp or have a damaged zip or face seal. Inspect, leak-check where required, repack, and record who did it.
Must be done, but may be scheduled with a documented plan:
- Lifeboat drill overdue (3 months 20 days) - schedule at the first safe opportunity after sailing or in sheltered water before departure; record the reason for the delay.
- Free-fall lifeboat overdue (7 months, no simulated launch) - same treatment; the requirement is six-monthly.
- Rescue boat overdue (4 months) - running the engine on the quay does not count as launching and manoeuvring.
- Release gear five-yearly examination due in one month - not yet overdue; book the attendance and hold the paperwork.
- HRU expiry in three weeks - replace before it expires, order the unit now.
Not a deficiency: the dynamic brake test certificate, if it is within its five-year cycle and relates to this davit.
2. State the intervals that apply to these items and explain what a port state control officer would look for in the records.

Intervals to quote:
- Each lifeboat is launched with its assigned operating crew aboard and manoeuvred in the water at least once every three months.
- Each free-fall lifeboat is launched with or without its assigned crew at least once every six months, either by free-fall or by a simulated launch carried out in accordance with the recognised guidance.
- Each rescue boat is launched and manoeuvred at least once every three months - running the engine in its stowage is maintenance, not a drill.
- Lifeboat falls are turned end for end at intervals not exceeding 30 months and renewed at intervals not exceeding five years, or earlier if deteriorated.
- The release gear is thoroughly examined at intervals not exceeding five years, and the winch brake is dynamically tested at those intervals at the specified overload.
- Disposable hydrostatic release units are replaced before the marked expiry date; serviceable units are serviced at intervals not exceeding twelve months.
What the inspector actually checks: the entry in the official logbook or the ship's planned maintenance record, cross-referenced to the drill, the personnel who attended, and the date. A launch claimed on a date when the ship was at sea in heavy weather, or with no accompanying maintenance record, is the pattern that attracts a deeper look. He will also compare the drill record with the boat's own records - hook inspections, fall renewal certificates, brake test reports - and will look for the defect reports that show whether the ship finds and fixes things before he does.
3. A junior officer suggests running the free-fall boat down its ramp using the simulated-launch procedure to clear the overdue item, and holding the lifeboat at the embarkation deck with no crew aboard to "count" the launch. How do you respond?
Read the worked answer
Both suggestions need to be corrected, and the way they are corrected matters as much as the correction itself.
The simulated launch is legitimate - but only within its rules. For free-fall lifeboats, a simulated launch is an accepted alternative to a free-fall launch, but it must be carried out in accordance with the recognised procedure and with the maker's instructions: the boat restrained, the release mechanism exercised as specified, and no one in the danger area unless the procedure requires it. It is not a shortcut around a blocked ramp or a defective release, and if the reason for the seven-month gap was that the ship could never comply, the record should say so and the flag administration should have been told.
The "launch" without a crew is not a launch. The three-monthly requirement is for the boat to be launched with its assigned operating crew aboard and manoeuvred in the water. Lowering it empty to the embarkation deck - or to the water - exercises the davit, which has its own maintenance value, but it does not satisfy the drill requirement and must not be signed as if it did.
The bigger point to make to the junior officer: the drill exists so that people find out, in controlled conditions, what it is like to launch and handle the boat. An entry that satisfies the paper and not the purpose is worse than an honest gap, because it means the next crew inherits a ship with a clean-looking record and an untrained complement. Record what was done, record why the rest was not, and programme the real evolution as soon as it is safe.
