摘要： A method and apparatus for heating a portion of a subsea structure is provided. The method includes pumping a fluid through a length of tubing such that the temperature of the fluid increases. The temperature increase of the fluid is created by friction in the tubing, and may be also be created by at least one pressure reducing device such as an orifice, pressure reducing valve, or relief valve. A subsea structure may be heated by transferring heat from fluid circulating in a closed loop configuration or by direct application of fluid to the subsea structure using a nozzle. A remotely operated vehicle may be utilized to transport some or all of the equipment necessary, including pumps, tubing, heat exchangers, nozzles and tanks. The remotely operated vehicle provides power to the pumps used for circulating fluid through the tubing.

摘要： Method for protecting subsea installations against cooling which leads to hydrate formation, in particular during production halts. This is achieved by thermally isolating portions of the installation (1) against the surrounding water (2), and particularly by completely encompassing the subsea installation (1) by means of a cap (3) which seals against the surrounding water (2). The cap (3) comprises several elements of which each separately can be exposed to cooling and internal hydrate formation. The invention also comprises a thermally isolating apparatus, adapted for protecting subsea installations (1) against cooling, which involves a risk for hydrate formation. An apparatus (3, 9) for implementing the method comprises a relatively tight-fitting cap (3) which encompasses at least two of the elements to be protected from cooling. Thus, the water inside the cap (3) is kept separately from the surrounding water (2) and evenly distribute the heat energy present under the cap (3) to all the elements encompassed by the cap.

摘要： A floating/tensioned production system for use in deepwater drilling and production operations generally combining a relatively small tension leg platform with a semisubmersible platform. The semisubmersible platform is provided with a working deck supported above the water surface so that an air gap exists between the working deck and the water surface. The tension leg platform provides a heave-restrained production deck for near-surface wellhead equipment. The production deck is supported above the drill site but beneath the water surface by buoyancy members and held in place by one or more tethers. Most other drilling and production equipment is located on the semisubmersible working deck. A caisson, surrounding the production deck, is used to provide a substantially dry working area. In one embodiment, the caisson is retractably attached to the production deck. In an alternative embodiment, the caisson is attached to the bottom of the working deck, extending downwardly to sealingly engage with the production deck.

摘要： An offshore structure for deepsea production of this invention is designed for achieving economy both in installation and in operation. It consists mainly of a base to be founded on a sea-bed, a buoyant body having a separator segregated from the sea for storing and separating the produced fluids and an elongate tensioned member for connecting the base and the buoyant body and transporting the produced fluids from the well through the base to the separator near the surface of the sea. The separator has a compartmentalized outer wall for controllably variable ballasting and deballasting.

摘要： A sea-floor cellar is installed in substantially in the sea-floor in a shallow water area where the distance between the sea-floor, which has a packed or rock ladened soil formation, and a drill ship is not sufficient to allow for normal positioning of a blowout preventer stack on the surface of the sea-floor. According to the method and apparatus of this invention, a first honeycomb of bore holes is drilled in the designated bottom area; a second honeycomb of bore holes having diameters larger than the first honeycomb of holes is then drilled into the designated bottom area to produce a second honeycomb of bore holes of larger diameter; and, a bar member is then rotated into the bore hole to eliminate soil structures left standing in the second honeycomb to produce a substantially clear recessed area for receiving the implantable sea-floor cellar to house a blowout preventer stack substantially below the surface of the subsea bottom.
