Dive control packages

Containerised dive control units are designed and built to customer specifications, with layouts tailored to suit specific requirements.

James Fisher Marine Services (JFMS) has extensive experience designing and manufacturing dive control units to suit specific customer applications. Our dive control units provide dive supervisors and client representatives with a quiet, warm and dry environment, free of distractions from which to safely oversee subsea operations.

Dive control units

Dive control units are designed to be modular with other JFMS dive equipment for ease of use and efficient operations, such as diver umbilicals, deck CCTV, DPA, deck communications, bridge communications, diver 1 and diver 2 video/audio output.

Fully insulated and lined, dive control units include all electrical distribution (single and three-phase) for container heating, cooling, lighting and all other electrical services. Dive control panels are available in two, three and four diver options for both air and nitrox diving operations. Containerised dive control packages are built to BS.EN:12079 or DNV 2.7.1 specifications as required. Sizes previously supplied include 12 x 8ft, 12 x 9ft, 15 x 8ft and 20 x 8ft containers.

Ancillary diving equipment

All ancillary diving equipment, such as diver communication, TV monitors, CCTV control units, hard disc video recording systems and diver monitoring can be provided in a 19" rack-mounted format, providing desk space for both the dive supervisor and panel operator.
