Ultra-deep water
Water depth exceeding 1 830 m (6 000 ft). NOTE 1 Since the physical circumstances of any situtation will change as a function of water depth, use of the term “ultra-deep water” implies that it may be necessary to consider design and/or technology alternatives. NOTE 2 For description of pressure and temperature ratings, the definition given in the applicable subsystem International Standard and other relevant standards and design codes is used.
