HSE Surface Supplied (Top Up)

This is the climax of air diver training and takes one week following successful completion of a recognised surface supplied diving course.

On occasion students who have worked in the inshore diving market will return and take this course as they progress their careers onto the offshore oil and gas fields found on many continental shelves.

The course is designed for divers wishing to work at maximum depths of up to 50m/165ft using equipment such as Hot Water Suits and Wet Bells.

The theory section provides a comprehensive understanding of the procedures used when working from a dynamically positioned vessel (DPV).

The Wet-Bell provides a professional and practical way for divers to access and egress the water in potentially rough conditions. It is also useful if deploying from a height above water comparative to what might be found on an oil platform or diving support vessel (DSV). A maximum of three divers can be lowered into the water to the worksite using the Wet-Bell and its clear acrylic dome provides a psychological 'safe haven' enjoyed by most who experience it.

Whilst its practicality is for transiting divers too and from the worksite, the safety features incorporated into the Wet-Bell system make it a valuable asset for any offshore diving operation. In addition to the numerous air supplies that the main bell umbilical provides, the Bell is also equipped with lighting, video and reserve air supplies that can be accessed by the diver by simply turning a valve lever.

The course is predominately based around emergency procedures such as diver recovery drills, loss or contamination of air supplies, loss of communications to the bell and complete system failure.

Students operate the air and hot water delivery panels located inside the dive control station and run the surface decompression profiles, with chamber operations taking place using the M.V. Sleat’s twin lock deck decompression chamber (DDC).

The stand alone Top-Up Course also provides students with the following equipment package.
