Nexans has provided to BP the first delivery in what will be the world’s largest and most complex Direct Electrical Heating (DEH) system to date.
Nexans is supplying a comprehensive subsea DEH system solution including complete system design and 130 km of cables with accessories for installation. This will provide flow assurance for 10 subsea flowlines serving the Shah Deniz high-pressure gas condensate development, located in the Azerbaijan sector of the Caspian Sea.
The Shah Deniz DEH contract, worth around Euro 100 million, forms part of a 10-year frame agreement between Nexans and BP, the operator of the project, to supply umbilical cables, DEH systems, accessories and services for various deep-water oil and gas projects worldwide.
“The key to Nexans’ success as a leader in DEH projects is our comprehensive systems approach that integrates the design of DEH systems, including engineering and manufacture of all the vital elements such as riser cables, piggyback cables, protection and accessories,” says Krister Granlie, Executive Vice President, Hybrid Underwater cables Division, Nexans Norway. “We are delighted to have achieved this important milestone in the world’s most complex and largest DEH project by completing the first delivery to BP.”
The first delivery consisted of DEH cables and accessories for four flowlines. The second delivery of the six remaining subsea systems is scheduled for 2016.
The DEH system for the 10 Shah Deniz flowlines is more complex than previous DEH projects. This is due to the multiple systems in close proximity and the unique operating environment in the Caspian Sea, the company said.
The cables and accessories will be manufactured in the Nexans’ facility in Halden.
