This story comes via our friends at the excellent blog Maritime Accident Casebook (MAC for short). Bob Couttie writes:

Of course you regularly check fire extinguishers for corrosion and environmental conditions that might encourage corrosion (You do, don’t you?) but what about the air bottles in your totally enclosed lifeboat?

It shouldn’t be necessary to point out that sea water will corrode gas cylindres but as the photos below show, it’s worth a reminder.

These are not new and come from a 2006 Schatt-Harding presentation to the Nautical Institute.

So check out those air cylinders to avoid a hurt bottom

We have covered this before but this report needs repeating as it comes on the tail of the gCaptain post Lifeboat Incident Video – Dropped From The Falls and MAC’s follow-up article

Davit Launched Lifeboat Freefalls.

Think this couldn’t happen aboard your ship? Last week Transocean’s new flagship, the Discoverer Clear Leader, arrived in the Gulf Of Mexico under much fanfare, soon after the visitors left the inspectors boarded a lifeboat and it dropped. Unconfirmed reports from our forum say no deaths but 4 men were emergency medivac’ed.

  • The disk will pop in an over pressure situation only. In this case corrosion caused catastrophic failure. The pressure was not increased so a relief device would not have prevented the explosive demise of the air cylinder.

    The are cylinder provides breathing air and air for the engine if operating in a toxic environment by providing a higher air pressure in the life boat than outside thus keeping out the the bad air.

    Don't these cylinders have a "burst disk" in the valves like scuba tanks do? It's designed to pop and let the contents out safely, rather than let the entire tank explode.

    What do they use these big cylinders for in lifeboats anyway?
