NATO Submarine Rescue System

[1] NSRS was designed and manufactured by Forum Energy Technologies' Subsea Division (NYSE Listed:FET formerly Perry Slingsby Systems).

It is capable of launch and recovery in a significant wave height of up to 5 metres (sea state 6) and can reach any distressed submarine (DISSUB) in 72-96 hours from the alert, dependent upon location.

The vehicle is based on the Forum Energy Technologies (FET) PSSL Triton SP ROV which is in widespread commercial use and is fitted with variable vectored thrusting.

It can carry a variety of tools to assist in removing debris and delivering emergency life support stores (ELSS) to the survivors through the escape/rescue hatch, in watertight pods, known as pod-posting.

It is the latest generation of rescue vehicle and has diverless recovery, fibre-optic data communications and a self-contained breathing system developed by Divex (now part of James Fisher Defence).

NSRS has operated from numerous mother ships and exercised to bottomed diesel submarines of NATO nations as well as those of Russia and Sweden.

In 2013 NSRS achieved a first by conducting a full rescue cycle with the nuclear attack submarine HMS Astute, which was suspended mid-water below large mooring buoys.

The TUP system is a fully autonomous and air transportable hyperbaric treatment facility that provides full decompression and medical support for up to 72 personnel simultaneously from 6 bar to ambient pressure.
