Crane vessel

Offshore contractor Seaway Heavy Lifting has announced the company’s crane vessel successfully installed the process unit (PU) topside for operator GDF SUEZ E&P UK and partners Centrica Energy and Bayerngas.

The Oleg Strashnov vessel installed the PU topside with a hook load of 4,700mt.

The PU topside was installed in the Cygnus field, which is located in the southern part of the North Sea.

"I am very proud of the vessel and her crew in successfully performing this record lift."

Cygnus comprises alpha wellhead, process unit, quarters unit and bravo wellhead platforms.

Seaway Heavy Lifting chief operating officer Peter de Bree said: "I am very proud of the vessel and her crew in successfully performing this record lift and would like to thank GDF SUEZ E&P UK Ltd for their confidence in Seaway Heavy Lifting’s on and offshore organisation when awarding this contract in 2012.

"In addition, I would like to thank everyone involved within Seaway Heavy Lifting, both on and offshore in achieving this milestone."

In 2014, the company’s crane vessel Stanislav Yudin installed the alpha wellhead platform, process unit jacket, quarters unit jacket and subsea structures.

The campaign will continue in 2015 with the installation of the bravo wellhead platform, process unit topside and compression module, quarters unit topside and connecting bridges.

Seaway Heavy Lifting’s Stanislav Yudin and Oleg Strashnov are certified to the highest standards and have a revolving lift capacity of 2,500mt and 5,000mt respectively.
