Heerema Vlissingen to set another record breaking fabrication project of the largest launch jacket ever built at HFG

Heerema Fabrication Group’s Vlissingen yard in the Netherlands signed the Letter of Award with Statoil for the Engineering, Procurement and Construction of a fixed jacket for the Dagny field development in the central part of the North Sea.

Following the award to HFG’s engineering firm –HFG Engineering- for the FEED study of the Dagny jacket in October 2011, Heerema Vlissingen received the Letter of Award from Statoil for the Engineering, Procurement and Construction (EPC) of this 16,000 tons launch jacket and a pre-drilling module of 155 tons last Friday 1 February.

The Dagny jacket will be the largest launch jacket ever to be constructed at HFG’s Vlissingen fabrication facility. Heerema Vlissingen will start the fabrication of this challenging and record breaking jacket in November 2013 with a planned delivery in April 2015. The jacket will be approximately 142 meters tall with a footprint of 60 x 50 metres and a top of 40 x 30 meters. The pre-drilling wellhead deck of 14 x 14 x 4 meters, will accommodate the phased development of the Dagny field and will eventually be integrated into the topsides cellar deck.

“This assignment will expand once more the design and fabrication capacities of our organisation, after the successful and challenging Statoil Valemon jacket project completed last year”, says Tino Vinkesteijn, CCO Heerema Fabrication Group. Tino continues: “Securing this contract will furthermore safeguard employment at our Vlissingen facility, which is currently fabricating four jackets, until the 2nd quarter of 2015.

According to VP Technology Cees Spaans of HFG: “Based on the various FEED concepts developed by HFG Engineering, varying from lift jacket to launch jacket, Statoil selected the launch concept. The fact that following this FEED study we have been awarded the EPC contract for the Dagny jacket after the successful Valemon jacket execution in 2011-2012, proves that our fabrication-driven engineering approach is the right direction.”

Remco van Gilst, Senior Vice President Commercial of Heerema Fabrication Group, comments: “Being awarded an EPC contract of this magnitude, demonstrates the confidence of our esteemed client Statoil in our capabilities and the relationship development during the recent execution of the Valemon jacket project. We are looking forward to working again with Statoil on this challenging project and to successfully integrate the interface management in order to accommodate the pre-drilling phase.”

The Dagny field development is a gas, condensate and oil field, located in the Norwegian central part of the North Sea, about 30 kilometres northwest of Sleipner. The Dagny field will be developed with a fixed platform in a water depth of 116 meters and will be tied into the Sleipner facilities for gas export with oil being transported by tankers.
