digest SCAR trencher completes trials
An innovative piece of underwater technology has just completed its first trials in the North Atlantic. Ecosse Subsea Systems’ trenching system, SCAR 1, ploughed a 20m wide, 1km stretch of seabed to the West of Shetland to remove boulders prior to umbilical and pipelay work.
Following the initial call, the Ecosse Subsea Systems team was able to design modifications to SCAR 1 to meet the demands of the rough terrain in just four days. Fabrication work was completed in 10 days, ensuring that the equipment provided a robust service in
Huisman, the specialist in lifting, drilling and subsea solutions based in The Netherlands, has secured a new contract from Allseas for the design and manufacture of an 850 tonne offshore mast crane. The crane will replace the 300 tonnes mast crane on board Allseas’ pipelaying vessel Solitaire. Delivery is scheduled for 1 October 2012 at the Huisman production
Dolphin Group has announced that through its subsidiary Dolphin Geophysical Inc it has acquired the entire stock of Open Geophysical (OGI).
As part of a one-year project to provide mooring and positioning support operations for Shell do Brasil, InterMoor do Brasil Ltda (InterMoor) recently beat the depth record for conventional mooring offshore Brazil with a water depth of 2,027m.
The project involves the mobile offshore drilling unit (MODU) Noble Clyde Boudreaux and will run until the middle of 2012. Operations focus on the Campos and Santos basins, but could be in any location off Brazil’s southeast coast in water depths ranging from 600-2,300m.
Andre Oliveira, project manager, InterMoor said: “We are committed to delivering safe, efficient and cost-effective mooring operations in support of this drilling campaign. There are challenges, so we have worked with Shell to plan everything in minute detail. This planning is essential if we are to continually break new boundaries such as the previous water depth record for conventional mooring offshore Brazil at 2,015m (well depth) and two of the eight anchors moored at 2,027m.”

Commenting on the project, Ecosse Subsea Systems’ founder and managing director Mike Wilson said: “Key to the success of these trials was the ability to provide a robust, reliable service in a very short time by listening to and working with our client.
“SCAR 1 has been adapted to meet the needs of this job and the adaptation has been created in such a way that it can be transformed and used as a backfill plough or for subsea boulder clearing. “That means the equipment will have huge potential for single-mobilisation
Allseas awards Huisman contract for 850 tonne offshore crane facility in Fujian, China.
The 850 tonne crane, with up to 1,600m hook travel on a single fall, will be equipped with an active heave compensation system on the main and whip hoist. The use of a splittable block on the main hoist allows the number of falls to be adjusted from eight to four without re-reeving.

InterMoor claims mooring depth record offshore Brazil
Intermoor’s contract covers the provision of engineering mooring analysis reports and conventional mooring. InterMoor has designed mooring patterns for the Noble Clyde Boudreaux at every drilling rig location. This involves a mix of open-water exploration work and mooring around subsea assets.
InterMoor assisted Shell in defining the
anchor-handling vessel specifications for the programme based on the final mooring system design, and supplies mooring coordinators, engineers and survey personnel on the rig and anchor-handling vessels to supervise and direct mooring system deployment, retrieval and connection to the rig.
Because of the water depths and the high loads, the anchor-handling vessels are high power with bollard pulls of 265 tonnes and are fitted with 3,000m work wires. The planning also considered the availability of mooring element spares as a critical measure to prevent unexpected major delays to operations.

multi-work scopes as SCAR will be able to perform seabed preparation, trenching and backfill.”
Damen Shiprepair Brest wins first contract under new ownership
Damen Shiprepair Brest in France has won its first contract since Damen acquired the former Sobrena Yard in Brest.
Bourbon Offshore Surf is to drydock Alcyon, one of its anchor handlers, at the yard. The work consists of a survey, a complete external paint programme, tank repairs and major steel renewal in the fore peak area.
Sartor Offshore
Rescue becomes Atlantic Offshore Rescue
Aberdeen-based standby vessel operator Sartor Offshore Rescue Ltd has officially rebranded to Atlantic Offshore Rescue Ltd, and says it achieved a turnover of £25 million in 2011. The company, which has been in operation since 1995, manages a fleet of 13 emergency response and rescue vessels and four platform supply vessels. It is part of the Atlantic Offshore Group (previously Sartor Offshore Group) which is based in Norway.
John Bryce, managing director of Atlantic Offshore Rescue, said: “As a name, Atlantic Offshore far better reflects the company’s core business which primarily supports international offshore oil and gas operations. We hope this will be a successful move for the company, allowing us to differentiate our service and vessels from so many other companies who include Sartor in their company name. “Our fleet of 13 vessels is currently all out on contract with 11 based in the North Sea, one in Brazil and another in the Falklands which is a new location for us to work in. Due to an increased demand for our services there are plans in place to invest in the expansion of our fleet and this will be ›››
