... dedicated topside VSD supplies one subsea pump via three-phase long stepout cables. However, such solution can be technically and economically ineffective for long tie-back applications due to relatively high-power losses and unacceptable levels of voltage drops along transmission cables. The development...

... Abstract The High Performance DEH-PiP is a new technology for electrical heating of subsea tie-back flowlines, that minimizes disturbances to the construction and installation process wrt. to standard PiP avoiding the use of internal heating cable, while reaching the same electrical efficiency...

... Abstract BOP tethering is a system installed around the wellhead with the purpose of stabilizing laterally the top of the BOP Stack through the action of cables, anchors, and other devices. This system, which significantly reduces loads on the wellhead, have been used in the last decade...

... that protects the insulation. Electrically Trace Heated Pipe-in-Pipe (ETH-PiP) technology is an adaptation of the standard PiP where electrical trace heating (ETH) and fiber optic (FO) cables are wound around the flowline, under the insulation, to provide active heating and temperature monitoring...

... heating to subsea pipelines enables i) field architecture simplification and ii) long subsea tie-backs. The Electrically Trace Heated Pipe-in-Pipe (ETH-PIP) is a standard reelable PIP system enhanced with up to 4-off trace heating cables and 2-off fiber optic (FO) cables, for temperature monitoring...
