It is also designed to withstand both internal and external pressure to 300 MSW and has a design temperature of -18 deg to +66 deg.

Each SDC is of “sinker” design without releasable ballast or attachment points and has an internal volume of 6m3 and 1900mm internal diameter.

The bottom door is a double acting castellated design with hydraulic actuation. The SDC has a retractable stage which is deployed during the launch.

The bell is equipped with a Mara 3-diver distribution panel for diver gas supply, DH21 Heaters and scrubbers for emergency life support and LP-20 lights. Externally the SC is fitted with a Divex emergency battery pack and Aquabeam 500w external lighting.
