NorSea starts recycling Renee/Rubie subsea manifolds

Offshore staff

ABERDEEN, UK – Endeavour Energy has contracted NorSea Group (UK) for disposal of the subsea manifolds and associated pipework from the decommissioned Renee and Rubie fields in the UK central North Sea.

All materials from the fields, 200 km (124 mi) northeast of Aberdeen, are being delivered to Smith Quay in Aberdeen, operated by NorSea Group. Endeavour stipulated maximized re-use, so NorSea Group has pledged to achieve a 100% recycling rate.

The returned material includes 1,000 metric tons (1,102 tons) of concrete mattresses which will be used as hard core and in road construction projects; 200 metric tons (220 tons) of pipework and skid units, to be recycled as scrap metal; manifold valves that will be refurbished and re-deployed; and a 17-metric ton (18.7-ton) crossover manifold which will be transported to the Underwater Center at Fort William, western Scotland, where it will be used for diver training.

 “This is our first decommissioning win and the first such project to be carried out in the northeast [of Scotland],” said Walter Robertson, managing director of NorSea Group (UK). “In the current economic climate we anticipate that many more decommissioning projects will be coming forward and we are already involved in tendering for additional contracts in this area.

“In addition to Peterhead we have facilities at South Quay, Montrose capable of carrying out similar types of small piece decommissioning work, so we see great potential for servicing additional contracts there.”

Smith Quay and Embankment, constructed by Peterhead Port Authority to service the DSV and subsea vessel sector, features 200 sq m (2,153 sq ft) of quayside and a draft of 10 m (33 ft). It can handle structures weighing up to 4,000 metric tons (4,409 tons). NorSea Group assumed operatorship under a 10-year agreement last summer.
