UK suppliers nab Mariner contracts

Saturday, June 28, 2014

Statoil (UK) has awarded two five-year contracts to two UK firms for the Mariner ultra-heavy oil field, in the East Shetland Platform in part-block 9/11a in the UK North Sea.

Aker Solutions' Aberdeen operations will perform maintenance and modification services for the US$7 billion project, with a planned August start. Aberdeen's Stork Technical Services will commence offshore operations services in January 2015. Both contracts include extension options of up to four years. Contract values were not disclosed.

The two companies join London-based compatriot Subsea 7 on the project, which was awarded a $170 million EPIC contract on 31 May.

Aker Solutions said that the maintenance planning system will be delivered in the pre-operations phase of the development, with support services delivered during the hook-up and commissioning phases. The contract includes maintenance and modifications services after the field is set to start production in 2017. 

Stork will deliver a myriad of services, including scaffolding, installation, painting, welding and logistics support during the hook-up and commissioning phase, followed by the operations phase from 2017 onwards. It will offer planning support starting in January 2015.

Mariner's development plan includes a production, drilling and quarters platform with 50 active well slots. It also features a floating storage unit, which will be constructed by Samsung Heavy Industries.

Discovered in 1981, Mariner is comprised of two reservoir sections, Heimdal and Maureen, which are located in 1227m and 1492m of water, respectively. The API gravities of the reservoirs vary from 12-14°. It is considered to be the largest offshore development in the UK in more than a decade. The is estimated by Statoil to contribute more than 250MMbbl reserves with an average production of about 55,000bpd. The final investment decision was taken in December 2012.

Statoil is the operator of the Mariner field (65.11%). Its partners are JX Nippon Exploration and Production (U.K.) (28.89%) and Dyas UK (6%).
