An easily-transportable 12-bunk accommodation module has been developed for use in RAN frigates.

The module would boost from 210 (standard configuration) to 222 bunks the accommodation on the FFGs.

To be positioned in the ship's hangar, when only one helicopter is embarked, the module is the concept of FIMA/Sydney and members of the ship's company of HMAS Newcastle.

"It comes in three sections," the commanding officer of FIMA/Sydney, LCDR Rick Barnett explained.

"Two sections carry six bunks each, the third is an ablution section.

"Bolted together they provide 12 bunks plus shower, toilet etc.

"With the middle section removed it comes down to a six-bunk module.

"The module is air-conditioned, has a door and safety 'kick-out panel' and is well appointed. Walls are made from honeycombed aluminium.

"The small fork lifts carried on the FFGs can easily move the sections," he said.

LCDR Barnett said an outside contractor built the basic module but FIMA/Sydney personnel did the fitting out. Cost was about $10,000.

He said the module will be a boon to the Sea Riding Group whose members often have to sleep in stretchers on a hangar deck.

"The module will also be ideal for ships wanting to take extra personnel to sea.

"Depending on what people think of the first one, we'll make a second to be positioned at HMAS Stirling."

Newcastle was due to trial the module this month.
