Abstract
An apparatus for storing tubulars on a floating semi-submersible drilling or production vessel. The apparatus comprises a storage device for storing tubulars in a submerged position, essentially below a splash zone. The storage device is generally open to the surroundings so that the tubulars are externally exposed to surrounding water. It is also described an apparatus for transporting tubulars between a storage and a derrick on an offshore drilling and/or production platform having a platform deck. The apparatus is situated below the platform deck and is adapted for movement under the platform deck. A method for disassembling a pipe string is also described.
