DOT 2015: GMC Ltd. highlights free standing hybrid riser

Offshore staff

THE WOODLANDS, Texas  ̶  GMC Ltd. representatives were present in the company’s Deep Offshore Technology International booth to discuss the free standing hybrid riser (FSHR). 

The FSHR is a vertical pipe tensioned by a near-surface buoyancy can with a flexible jumper. The jumper then connects the top of the steel riser to the production pipeline.

GMC’s FSHR does not require welding, instead using mechanically connected pipe. It also uses higher grade steels (110 ksi and up) to reduce thickness and riser weight for ultra-deepwater applications.

It has been deployed in deepwater areas such as the Gulf of Mexico and Brazil. It can be used in high-pressure/high-temperature.

GMC said that the product allows for significant cost-savings, as only one installation vessel is needed, compared to the multiple vessels typical in the industry. Another potential cost-saver is the elimination of welding, could also allow for a more rapid installation.

GMC Ltd.’s Intelligently Connected Pipe (ICP) was recently recognized by ASME as a finalist in its Global Pipeline Award competition.
