The 2-minute primer

New to this? These 6 cards explain the lesson in plain words. Go through them first and the lesson will make sense.

  1. 1/6Picture this

    You can bleed a radiator, not open the boiler

    At home you can set the heating, bleed a radiator or read the boiler’s pressure gauge. But opening up the gas boiler itself is a job for a qualified engineer, however handy you are.

    Lifeboats have the same split. Some jobs belong to the crew. Others need a certified specialist.

  2. 2/6The big idea

    Three levels of work, two sets of hands

    The crew do the weekly and monthly checks and the routine maintenance in the maker’s manual, under a senior officer.

    The annual examination, the five-yearly work and any repair need technicians certified for that make and type. They must work for the maker or for a service firm the flag country has authorised.

  3. 3/6Words you'll meet

    Five words, in plain English

    Routine maintenance
    simple care, like greasing, that the maker’s manual describes for the crew to do.
    Repair
    any job that needs equipment taken apart, or that goes beyond the on-board manual.
    Authorised service provider
    a service firm approved by the ship’s flag country for that equipment.
    Certified technician
    a person trained and assessed for a make and type; the certificate lasts three years.
    Flag Administration
    the government of the country where the ship is registered.
  4. 4/6Why it matters

    Release gear punishes guesswork

    Release gear is complex and differs from maker to maker, and mistakes with it have killed people. Before the rules changed, the annual work only had to be done by “properly trained” people, which left a lot of room.

    Now the line is clear. A crew member who takes a hook apart to help is doing repair work they may not do.

  5. 5/6In this lesson

    What you’ll be able to do

    • Sort lifeboat jobs into crew work and specialist work.
    • Use a simple test to tell maintenance from repair.
    • Check that a service firm and its technician are approved for your equipment.
    • Know how different flag countries handle approval.
  6. 6/6Quick check

    A hook must be taken apart. Who does it?

In plain words

Some lifeboat work is the crew’s job. Some of it the crew must never do, however experienced they are.

The crew look after the boats day to day. They do the weekly and monthly checks, run the engines, swing the boats out, and do the routine maintenance the manufacturer’s manual describes, all under a senior officer.

The bigger jobs are different. The annual thorough examination, the five-yearly overhaul and load tests, and any repair must be done by technicians trained and certified for that make and type of equipment. They must work for the manufacturer or for a service firm the flag State has authorised.

The dividing line is simple to remember. If the job is in the on-board maintenance manual and doesn’t need anything taken apart, the crew can usually do it. If not, call in the specialists.

Key points

  • Weekly and monthly inspections and routine maintenance from the manual: authorised service providers, or the ship’s crew “under the direction of a senior ship’s officer” (MSC.402(96) §4.1).
  • The annual thorough examination and operational tests: certified personnel of the manufacturer or an authorised service provider (MSC.402(96) §4.2).
  • The five-year examination, any overhaul, overload tests and any repair: certified personnel of the manufacturer or an authorised service provider (MSC.402(96) §4.3).
  • “Repair” means any work that needs equipment taken apart, or anything outside the on-board maintenance instructions (MSC.402(96) §2.2.6).
  • Technicians are certified for each make and type, and their certification expires three years after issue (MSC.402(96) §8.1, §8.3.1).
  • Service providers are authorised by the flag Administration, which may accept providers authorised by other Administrations or their recognised organisations (MSC.402(96) §3.1, §7.4.3).
