Scana Industrier ASA has through its subsidiary Scana Subsea, been awarded contract to deliver machined riser forgings to an undisclosed client.
The riser systems are intended for North Sea and Australia operations.
The initial contract value is 27 MSEK (USD 4.09 million). The contract contains additional optional work as machining, welding, assembly and testing, which may increase the total contract value higher.
The projects are planned to start immediately and deliveries will commence in 3rd quarter 2013. The contract will also involve Scana Steel Björneborg, Scana Steel Söderfors and Scana Machining, in addition to Scana Subsea fronting the contract.
Helix Energy Solutions Group’s new T1200 burial and trenching unit is quickly establishing a positive track record following the completion of an oil and gas project in the North Sea. The T1200 features a 1,200hp jet trenching spread, capable of burying product in water depths to 3,000m (10,000ft).
T1200 was deployed to bury a 14km long (8.7 mile), 10 inch export pipeline that included a 3 inch piggyback methanol line. The project specialization called for the line to be buried 2m (6.5ft) deep, with one meter of covering fill. The subsea trenching unit’s water jetting system trenched and simultaneously buried the pipeline under 1.4m (4.5ft) of sand in a continuous run that took just 48 hours.
The successful project is the T1200’s first oil and gas operation, and proves the versatility of the asset which has also been deployed to trench and bury high voltage undersea cables used to transport electricity from offshore wind farms to onshore power stations.
The T1200, operated by Helix ESG’s robotics subsidiary, Canyon Offshore, performed its first trenching job in early July 2012 at the Sheringham Shoal offshore wind farm trenching and burying an approximately 700m (2,300ft) long power cable between the wind turbines. Out of the 80 sections required in the field, the T1200 trenched and buried 37.
The T1200 was built in the UK by Forum Energy Technologies’ Perry Slingsby Systems ROV brand. The T1200’s design was based around the time proven T750 trencher( also owned and operated by Canyon Offshore) but has over 50 percent greater power and the capacity to trench larger diameter products (36 inches) to burial depths of 3m (10ft) depending on soil strength.

McDermott International, Inc. announced that its Malaysian affiliate Berlian McDermott Sdn. Bhd. was recently awarded a significant subsea contract for executing a deepwater engineering, procurement, construction, transportation, installation and commissioning project offshore Malaysia. The value of this contract is included in McDermott’s first quarter 2012 backlog.
The award is for the subsea infrastructure of the Siakap North – Petai (“SNP”) Development Project operated by Murphy Sabah Oil Co., Ltd. (“Murphy”), comprising rigid flowlines, flexible risers, an umbilical and subsea hardware and controls. The SNP field is located nearby the existing Kikeh field, northwest of Labuan Island, Malaysia, in waters 3,900 – 4,900 feet deep.
“Our subsea engineering expertise, fabrication track record at our Batam Island facility, state-of-the-art subsea construction vessels and understanding of the Malaysian market, contributed to this successful award,” said Stephen M. Johnson, Chairman of the Board, President and Chief Executive Officer of McDermott. “We look forward to delivering the facilities for this important field development for Malaysia.”
The SNP field architecture consists of two rigid, insulated, pipe-in-pipe production flowlines, one rigid water injection flowline and one main umbilical system connecting eight new manifolds and subsea distribution units to existing riser slots on the Kikeh FPSO. The development calls for five water injection and eight production wells, drilled from the manifolds at each of the four drill center locations.
Detailed engineering and procurement for the project are underway, and fabrication of PLETs, jumpers and other installation aids is expected to begin in the third quarter of 2012. Following the infrastructure installation, McDermott will undertake a comprehensive System Integration Test of the subsea units and provide commissioning assistance. The project scope is scheduled to be completed by the third quarter of 2013.
