Platform installation,
De Ruyter field

The De Ruyter field, discovered in 1996, straddles Blocks P10a and P11b in the North Sea, which are both operated by Petro-Canada. The development consists of a Gravity Base Structure (GBS) with wellhead and lattice towers supporting an Integrated Production Deck (IPD). De Ruyter joins Hanze as Petro-Canada’s second operated offshore field in the Dutch North Sea. Heerema Zwijndrecht was awarded the fabrication, installation and hook-up of the GBS and IPD. The transportation, installation and stabilisation of the GBS was subcontracted to a consortium between Smit Marine Projects and Boskalis Offshore.

Crucial in the design was a proper foundation of the platform, which was complicated by the presence of a silty clay layer a few meters below the seabed, overlying silty sands with silt sublayers. To provide a suitable base on which to position the GBS, sea bed improvements were necessary, which consisted of the removal of 5 meters of material below existing seabed level. After installation the GBS and surrounding soils required further ballasting and stabilisation with rock.

Jotun A

The Jotun A FPSO, a 92,000 DWT FPSO capable of producing 70,000 bpd, began producing in 1999 on the Jotun field (Norway). As part of Vår Energi’s investment in increased oil recovery from the Balder field in the North Sea an upgrade of the Jotun FPSO is required. The Balder Future project will extend the life of the field (PL 001) by 2045, giving Norway’s oldest license a lifetime of 80 years.
