We have had the honor to work as consultants for Equinor (Statoil) on these major projects. It has been a journey and a pleasure to see these great projects evolve.
Martin Linge Topside
The Martin Linge project is a new project for EIT Engineering. EIT Engineering has been involved in this project since beginning of June 2018 and will follow the project until production start.
The Martin Linge field in the North Sea is an oil and gas discovery that was made in 1975. The field is located 42 kilometres west of Oseberg, at a water depth of 115 metres. Equinor became the operator of the Martin Linge field and Garantiana discovery in a transaction completed on March 19, 2018.
The field development concept includes an integrated wellhead, production and accommodation platform with a jacket, in addition to an oil storage vessel. When the field comes on stream, the gas will flow through a new pipeline connecting the field to the existing pipeline to St. Fergus in Scotland. The oil will be processed on the storage vessel and transported from the field in shuttle tankers.
Equinor aquired this project after Total decided to sell it´s stake in the project.
MARINER A (Equinor)
We are currently engaged in this exiting project, the biggest to be built in several decades and and a complexity to rival a moon landing some once told me.
Mariner—a new era for Statoil on the UK continental shelf
The steel jacket was installed in the field during the summer of 2015. The topsides modules are being constructed by Daewoo Shipbuilding & Marine Engineering Co., Ltd. (DSME).
The Mariner oil field consists of two shallow reservoir sections: the deeper, Maureen formation at 1492 meters and the shallower Heimdal reservoir at 1227 meters. The oil is heavy with API gravities of 14.2 and 12.1 and viscosities at reservoir conditions of 67 cP and 508 cP, respectively for Maureen and Heimdal.
Heavy oil projects have required the development of pioneering technology. Since its discovery in 1981, the Mariner field has been subject to a number of development studies by different operators. Statoil was the first company to put forward a development concept that will fully address the complexities of this field.
Heavy oil field discovered in 1981
Recoverable reserves estimated at 250 million barrels of oil
Statoil became operator of the Mariner field in 2007
Average plateau production will be 55,000 barrels per day
30-year field life
The Valemon project was a huge part of our life. From Norway to Kuala Lumpur to Netherlands, To Korea and back. This journey took us 3 years to complete.
The Valemon field is one of Statoil’s stand-alone development projects on the Norwegian continental shelf. Containing about 192 million barrels of oil equivalent the field will be producing through a separate platform.
Due to its fragmented high-pressure, high-temperature qualities, Valemon is a complex reservoir.
The gas from Valemon will be sent through the existing pipeline between Huldra and Heimdal, which is a hub for further transportation to the European gas markets.
The condensate will be piped to Kvitebjørn for stabilisation and from there to the Mongstad refinery near Bergen. A submarine cable will supply Valemon with electricity from Kvitebjørn.
A gas and condensate field between Kvitebjørn and Gullfaks Sør in the North Sea, about 160 kilometres west of Bergen.
Unmanned fixed steel platform with separation facilities for gas, condensate and water.
The field is tied in to existing infrastructure through subsea pipelines
The plan for development and operation (PDO) for the Valemon field was approved by the Ministry of Petroleum and Energy in June 2011.
