Perth-based TSmarine Asia Pacific has been awarded the Halyard Field Development offshore installation contract valued at more than $AU22m by Apache Energy Limited.
The contract involves transporting and installing 16km of flexible flowline and 28km of control umbilical connecting the Halyard 1 well to Apache's operations hub on Varanus Island off Western Australia's Pilbara coast, via the existing East Spar subsea infrastructure. Control will come from the existing John Brookes wellhead platform.
TSmarine Regional Sales and Marketing Manger, Ian Rowson, said the Halyard contract demonstrated Apache's confidence in TSmarine's capability to undertake large-scale projects.
"Our new construction support vessel, Bourbon Oceanteam 104 (B104) will be deployed to undertake this work, which brings a new level of capability to the Asia Pacific region in terms of offshore construction and intervention," Mr Rowson said.
"We are continuing to build our presence in the Asia Pacific Region. The B104 complements our existing fleet, offering greater construction capability and flexibility. It is well suited to the large -scale projects set to be developed in the area in coming years."
The B104 - fitted with two active heave compensated cranes rated at 250T and 110T - is a large dynamically positioned construction support vessel with 2,400m² back deck space allowing up to six flowline reels to be transported and installed in a single mobilisation while still leaving large areas clear for additional project equipment.
As part of the Halyard development, TSmarine will install on Apache's John Brookes platform three new modules which have been designed locally and fabricated at the Australian Marine Complex in Henderson, Western Australia.
The flowline and umbilical, to be provided on a total of 11 reels, will be collected in Europe and transported to Australia on a heavy lift vessel. The reels will then be transferred to the Bourbon Oceanteam 104.
The offshore works are scheduled to commence in February 2011 and are expected to take 45 days.
