Hanze F2a Development Project

Hanze, 200 kilometers offshore Den Helder in block F/2 of the North Sea, is the first operated development in the Dutch sector by Germany's Veba Oil. The oilfield reserved approximate 34 million bbl, plus 40 bcf of associated gas. 

The field has been developed with nine wells, using an 8,100-ton production platform and gravity base. In this 15,600 ton GBS, which has a capacity of 150,000 bbl, oil is stored after being processed at the platform. The GBS comprises a 14-m high steel tank with skirts underneath and a framed tubular structure. Hyundai Heavy Industries were the main contractor on the Engineering, Procurement, Installation & Commissioning project (EPIC), with Smit Maritime Contractors as the installation (sub)contractor. Boskalis Offshore was awarded all seabed rectification works and executed them with full dedication of spreads and resources.

Deepening of the Eems-pipeline

The 42" Eems pipeline is part of the pipeline connection between the gas cleaning and drying plant of Phillips Petroleum at Rysumer Nacken in Germany, and the natural gas pipeline network in the Netherlands. The gas is obtained from the Ekofisk gas field in the Norwegian region of the North Sea. The pipeline crosses the morphologically dynamic Eems estuary over a length of 4 km, passing both the deep shipping lane ‘Oostfriesche Gaatje’ and the shallow sand bank ‘Paap’.

Development gas export pipeline,
Hibiscus to Point Fortin

The NCMA Development Project comprised the development of the North Coast Marine Area, which is located in the Caribbean Sea and Bay of Paria, Trinidad. The project included the installation of a 24" Gas Export Pipeline from the Hibiscus Platform to a landfall at Point Fortin. From the landfall the pipeline was routed by directional drilling and by surface laid pipeline, to a termination point in the Atlantic LNG Terminal at Point Fortin. As part of this project Boskalis was awarded the contract for the provision of landfall, directional drilling and onshore pipeline installation and testing of the 24" gas pipeline system.

Installation gas pipeline, Takoradi

Late November 1998 Boskalis was awarded a subcontract for the installation of two marine pipelines to supply and discharge cooling seawater for the Takoradi thermal power plant that was under construction for the Volta River Authority, near the village of Aboadze approximately 20 kilometers north-east of Takoradi, Republic of Ghana.

Re-insulation Gannet 'C' Bundles, North Sea

The Gannet 'C' satellite field, which is located in the North Sea at 112 miles East of Aberdeen in 95-meter water depth, comprises four drill centres, each having one or more producing wells. The drill centres are connected to the local platform Gannet 'A' by four flowline bundles with a total length of 10 kilometers. A glycol-based gel, filling the annulus of the Gannet 'C' carrier pipe, insulated the individual flow lines. Prompted by degradation of the gel and the resulting drop in oil and gas arrival temperatures at the platform, an EPIC project took off for a re-insulation system. The objective of the re-insulation system was that it should provide sufficient insulation to the bundles in order to safeguard production during the total field life of Gannet 'C', being a minimum lifetime of 15 years. Boskalis Offshore was supported by Hydronamic - the in-house engineering department.
