MonArb jacket departs OGN for North Sea

Offshore staff

WALLSEND, UK – OGN Group has delivered the 5,745-metric ton (6,333-ton) steel jacket for Talisman Sinopec Energy UK’s MonArb area redevelopment (MAR) project in the UK central North Sea.  

The 118-m (387-ft) tall structure will support the new oil and gas production platform. This will be bridge-linked to the existing Montrose platform that was installed by original operator BP in 1975.

During the 18-month construction program OGN employed a team of more than 700. Following completion, the jacket was loaded onto a 150-m (492-ft) long transportation barge moored alongside OGN Group’s Hadrian Yard on the north bank of the River Tyne in northeast England.  

On arrival at the field, 210 km (130 mi) east of Aberdeen, the jacket will be installed alongside the existing Montrose platform. The MAR Project will integrate the undeveloped Cayley and Shaw fields with numerous older ones already in production.  It is expected to lead to production of an additional 100 MMboe and extend the life of the existing fields to 2030.
