Maria Water Injection from Heidrun

Aibel conducts preparatory work related to water injection from the Heidrun platform to the Maria field.

In spring 2015, Statoil awarded Aibel the assignment to increase the
water injection capacity of Heidrun and perform the tie-in of the water
injection from the platform to the Maria field. The contract, comprising of engineering, procurement, construction and installation services (EPCI), is valued at NOK 860 million.

The job includes various modifications. Initially, Aibel will expand the
riser balcony on Heidrun. A temporary winch for the pull-in of a new riser will later be installed at the balcony.

To increase the water injection capacity at Heidrun, a new water treatment system will be built at Aibel's yard in Haugesund. The system will be built as one module before it's tested, disassembled and shipped out to Heidrun in smaller pieces. This is a more cost  effective solution than hiring a heavy lift vessel to hoist the complete module.

Before the new module can be installed, Aibel will construct a new deck for the module to stand on. In addition, Aibel is overhauling the existing water injection system on Heidrun and relocating a Man Overboard Boat (MOB ).

The main start of the offshore work will be in January 2016. The project is scheduled for completion in spring 2018.
