This 300 mtr twin lock decompression chamber was manufactured by Mollerodden (Norway) in 1977. The chamber was fully refurbished in 2007. Part of this was to extend the main lock by 1.3 mtrs to increase the capacity from 4 to 6 Man. The chamber was fully shotblasted and repainted new insulation and over cladding new viewports. The approximate external outfitting and internal outfitting of the chamber is as follows:-

This is a single lock 6 Man chamber with a spherical TUP permanently attached. The manways on the TUP section of the chamber are inter-changeable with removable penetrator plates bolted into position.

Additionally the single lock chamber is fitted with a medical lock.

The single lock chamber and TUP are mounted on a heavy duty skid. The single lock chamber was extended from 3 to 6 Man in 2008. This was done with full Approval Build Survey and Certification from Lloyds Register of Shipping.
