Intelligent Transponder Surveyingubsea units and greater operational flexibility. Equipment has to be robust, portable and able to operate at any required depth in all sea states. Operational performance is also expected to be unaffected by the ship’s noise or environmental constraints, and not to interfere with or be affected by acoustic systems already in use.

Slippery Paintr tropical waters, deep water or inshore trading, polluted or fresh-water dock, etc. Offshore structures have wide and varied fouling populations even on those located within several miles of one another, and indeed it may take several years before a stable pattern of fouling is established upon the platforms.

Hutton Production Risers—A Novel Cleaning Problem (an up-to-the-moment case history)elatively fragile, coating of flame-sprayed aluminium (FSA). There is a requirement to keep these risers free of marine growth, and the challenge was offered to a wide spectrum of UK-based companies to come up with a viable, and necessarily innovative, system to remove this marine growth without damaging the FSA.

Designing for Intervention Drilling—ROV can reasonably be done to reduce this figure is highly beneficial. This chapter addresses the cost savings which can be realized in a drilling program through the design and interface of an underwater intervention system for drilling support.

Recent and Future Developments in Undersea Survey and Interventiondevelopment of underwater systems for deep-sea survey and intervention. Thanks to this policy, IFREMER has developed and operated, through its subsidiary company GENAVIR, a panoply of the world’s best manned submersibles, towed and remote controlled vehicles, equipment and tools specifically suited to deep-sea exploration and work.
