    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: A method of sealing an annulus between inner and outer pipe sections (18, 12) of a pipe-in-pipe system comprises: positioning a sealing mass (30) in the annulus in contact with the inner and outer pipe sections; deforming the sealing mass, for example by shearing and compression, by effecting relative longitudinal movement between the inner and outer pipe sections; and fixing the inner and outer pipe sections against reverse relative longitudinal movement to maintain deformation of the sealing mass. The inner pipe section and a displaced outer pipe section may be fixed by welding them to respective pipes of an adjoining pipe-in-pipe structure. Opposed ramp surfaces, each being similarly inclined relative to the longitudinal direction, extend into the annulus from respective ones of the pipe sections such that the sealing mass may be compressed between the ramp surfaces.
