OTC.13: Subsea 7 technology focus

May 2, 2013

Subsea 7, a global leader in seabed-to-surface engineering, construction and services, will be exhibiting its innovative technologies and why it is the technology partner of choice for many in the offshore energy industry, at OTC 2013 from 6 to 9 May in Houston, USA.

Subsea 7 will deliver seven conference papers at OTC and, among the range of technologies the company will be exhibiting at its booth (1641), will be its:

  • market leading work in Electrically Trace Heated Pipe-in-Pipe (ETHPIP),
  • award winning Bubi® Mechanically Lined Pipe technology, which has also been shortlisted for an ASME award, and
  • advanced welding techniques from its newly operational Global Pipeline Welding Development Centre.

Also on exhibition will be a model of Subsea 7’s Autonomous Inspection Vehicle, which is set to make a step-change in future underwater operations, and its flagship vessel the Seven Borealis.

Steve Wisely, Subsea 7’s Executive Vice-President Commercial, said: “As subsea projects continue to increase in size and complexity, and they are more frequently executed in deepwater and harsh environments, new technologies and capabilities have to be developed to meet the new operating challenges. At Subsea 7, we are investing in R&D and in our fleet to develop these new technologies.”
