Valemon Topside EPC

In May 2011, Statoil awarded Samsung Heavy Industries (SHI) the EPC contract for delivery of the Valemon Topsides and LQ. Grenland Group teamed up with Samsung as their engineering partner and for fabrication of the flare.

About Valemon

The Valemon field is located west of Bergen, approximately 12 km west of the Kvitebjørn installation. The Valemon development is currently one of the largest industrial projects in Norway. The investment budget is 20 BNOK including the actual installation, new pipelines and modifications on other platforms. In total, over 25,000 man-years will be used in the project.

Valemon is a HPHT gas condensate field, with pressure depletion as the drive method. When the pressure drops upon reservoir depletion, modifications to include compression will be performed. The process deck will include facilities for gas-condensate-water separation. Rich gas will be exported to Heimdal via the Huldra pipe, unstable condensate will be exported to Kvitebjørn, and produced water will be injected into the Utsira formation.

The platform will be built for Normally-Not-Manned (NNM) operation, with control and power umbilicals from Kvitebjørn. The topside includes a living quarter with 40 cabins for use during the hook-up/commissioning and drilling period, as well as for future maintenance and modifications.

Grenland Group in Valemon

Samsung is the EPC contractor for the Valemon deck, and will perform project management, procurement and construction. Grenland Group and Technip (Malaysia) are Samsung's engineering partners in the project.

GG's scope of work includes:

Engineering

• Integrated engineering team with TP. GG will have the leads the NORSOK intensive disciplines and deputy leads on the other disciplines.
• System engineering
• NORSOK advisory/verification function on all engineering activities
• Package engineering (technical procurement)
• User manuals

Assistance to SHI's project management team

• LCI management
• Interface management

Flare fabrication

Hook-up and offshore commissioning assistance to Statoil (option in the contract)

Execution model

Initial Engineering Phase

The project started in Sandefjord, and is now continued in Kuala Lumpur in Malaysia.

A 6 months initial engineering phase has been performed in Sandefjord, with a team of 65 GG engineers. Including Samsung, TP, Statoil and others, around 150 people have been working at the location this autumn. The main tasks to be performed are FEED verification, development of philosophies, specifications and standards, system engineering and package engineering to lay the grounds for further detailing in the main engineering phase.

Main Engineering Phase

After 6 months, most of the project team moved to Technip's offices in Kuala Lumpur for engineering completion up to issued for construction status. A team of 25 GG engineers has relocated to Malaysia to perform assistance and verification activities for the integrated team.

Construction Phase

Samsung will perform the construction at its offshore yard on Geoje Island (South Korea). Steel cutting will be performed in spring 2012, and delivery is planned for February 2014. A team of 10-15 GG engineers will follow the team to Geoje to perform follow-on engineering and fabrication assistance.

The living quarter will be supplied by Hertel Offshore in Holland, and then transported to Korea for mating with the deck. In parallel, GG will perform the flare fabrication at its yard in Tønsberg.

Hook-up and Commissioning Phase

After delivery from Geoje, the topside will be transported to the Valemon field for installation. GG has proposed an option for hook-up and commissioning assistance to Statoil, which will be executed at a later stage.

First oil from Valemon is scheduled for October 2014.
