Offshore staff

HOUSTON -- Bisso Marine and Harvey Gulf International Marine are teaming to form Harvey Bisso Subsea, a new venture that will provide subsea services to the energy and maritime industries.

The centerpiece of the venture is a new, fully-classed 12-man saturation diving system with a working depth of 1,000 ft (300 m). The portable SAT system will be deployed from the multi-purpose support vessel Harvey Discovery.

The new SAT system features a gas reclaim system, which allows expelled gases to be circulated and recycled. It has a dual-lock, six-man deck decompression chamber, a 12-man launch-able flyaway hyperbaric rescue chamber, a dual-lock, six-man come-out chamber, and a three-man diving bell.

The portable diving system has a bell launch and recovery system, a saturation dive control van, and two machinery vans. It has a 12-ton (11-metric ton) main bell winch and a 6-ton (5.4-metric ton) guide wire winch. The bell umbilical is 1,150-ft (351-m) long and the bell handling system is a hydraulically actuated A-frame. The system is fully classed by ABS and IMCA compliant.
