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.

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.

Pipeline construction, Mumbai Highfields to Uran Trunkline

The Mumbai High Fields to Uran Trunkline Project is situated near Mumbai (Bombay) in India. ONGC Ltd (Oil & Natural Gas Corporation) has constructed two new pipeline connections from the Mumbai High Fields to Uran over a total length of 204 kilometers. These new pipelines have been constructed in order to replace the existing Bombay High Fields to Uran Trunkline, which had already completed more than 25 years of successful operation and had surpassed its design life. The new pipelines are a 30" oil pipeline and a 28" gas pipeline.

Construction gas pipeline
Beachfield Upstream
Development

The BUD project entailed the construction of a 66 kilometer, 36" gas pipeline, 63 kilometers offshore and 3 kilometers onshore underground to the treatment facilities. The offshore pipeline runs from the east coast at Beachfield (Rustville), Guayaguayare, to the 'Cassia B' platform complex. At the NGC Abyssinia facilities, 3 kilometers off Beachfield, a new sludge catcher has been developed to separate the liquid or condensate from the natural gas. The condensate is separated from water and metered. The station is also designed to control the pressure of gas, as it enters into the land gas transmission system. NGC's existing 30" and 24" gas pipelines have also been diverted to the new Abyssinia sludge catcher.

Seabed preparations, Changi Outfall

The Public Utilities Board implemented the Deep Tunnel Sewerage System as a long-term solution to meet the needs for sewerage water collection, treatment and disposal to help maintain Singapore’s clean and healthy environment. In phase one of the Deep Tunnel Sewerage System, the Changi Water Reclamation Plant was constructed in the east of Singapore, from which the Changi Outfall was subsequently constructed. Treated effluent from the water treatment plant will flow through outfall pipelines and be discharged through series of diffusers, dispersing the effluent in the seawater. Boskalis International was awarded the contract for the Changi Outfall in 2002 and formed a joint venture with Archirodon to construct the project.
