Subsea World News has put together a recap of the most interesting articles from the previous week (October 10 – October 16).
DEA has awarded the EPCI (engineering, procurement, construction and installation) contract for the smaller structures and pipelines, as well as the subsea installation work of the Dvalin development to Technip Norge.
The contract includes the fabrication of smaller structures, the 12/16-inch pipe-in-pipe production flowline, the 12-inch gas export pipeline and the installation of pipelines as well as all subsea structures and umbilical for the Dvalin field.
Hurricane Energy has provisionally selected Technip and FMC Technologies, under their alliance, as its exclusive provider of subsea solutions for the Lancaster Early Production System (EPS) and for subsequent development of the Greater Lancaster Area.
Located in UK blocks 205/21a, 205/22a and 205/26b, Lancaster presents the first basement prospect drilled by Hurricane and proved to be a significant discovery.
The tunnel, with the length of approximately 25.5 km, starts in Harestad in Randaberg and ends at Arsvågen in Bokn. In addition to the main tunnel there will be an arm up to Kvitsøy with a length of approximately 4 km.
The agreement will include support to weld qualification, routine mechanical testing of materials, corrosion testing, and fatigue testing, the company informed.
Aker Solutions and MAN Diesel & Turbo are said to expect to cut the size and weight of subsea compression systems by at least 50 percent just a year after the first such system successfully went on stream at Statoil’s Åsgard field.
The Åsgard system, which has been running with practically no stops or interruptions in its first year, should help recover an additional 306 million barrels of oil equivalents more cost-effectively, safely and with a smaller environmental footprint than a traditional platform.
