Alex Rimmer, 2H Offshore, UK and Edward Elletson, Pulse Structural Monitoring, UK, describe a real time monitoring system for measuring the structural response of a high pressure drilling and completion riser in the North Sea.

44 A mean, clean, oil recovery machine
As more oil and gas production technology moves from the surface to the seabed, subsea water treatment is lagging behind. Eirik Dirdal, Seabox, Norway, discusses how the results from the world’s first full-scale pilot of a subsea treatment plant could be a game-changer.

49 Controlling flow at greater depths
Ben Wait, Trelleborg Offshore & Construction, UK, discusses why operators are focusing less on economics and putting increasing emphasis on project specific qualification and product reliability when it comes to subsea architecture and pipeline insulation coatings.

53 New technologies for a new environment
Svein Erik Gregersen, Emerson Process Management, Norway, explores the developments in subsea multiphase meter technologies that are helping these devices operate in ever-harsher conditions.

58 Stay awhile by the Nile
Mike Main, Viking SeaTech, UK, highlights the challenge of applying the latest subsea mooring technology offshore Egypt.
