Aquaterra Energy’s recently launched RISER MONITORING SYSTEM has been developed to prevent risers from being used beyond their expected fatigue life. It combines direct strain measurement, subsea data logging and riser analysis.

DNV GL is leading a joint industry study to develop design guidelines for CONCRETE COATING OF PIPELINES. Members of the JIP includes Petrobras, Saipem, Bredero Shaw, SVAP and Wasco Coatings.

While on pipelines, The Welding Institue and Swagelining have joined with Saudi Aramco in a JIP on the use of polymer lined pipes for SOUR SERVICE. The two phase study will both test sections of lined pipe to determine corrosion rate, while testing for liner collapse plus study the flow regime.

Aker Solutions has completed development and fabrication of a subsea containment assembly (sca), part of SUBSEA CAPPING SYSTEM, which will be delivered to the Marine Well Containment Corp which will own the system for use in the Gulf of Mexico. The 15Kpsi 170t sca is a series of adapters and connectors for directly flow from a well.
