GS-Hydro solution: Delivery and installation of hydraulic non-welded piping solution for Blackford Dolphin semisubmersible offshore drilling platform

Year: 2008
Segment: Offshore

GS-Hydro completed a series of piping project deliveries for the upgrade of the Blackford Dolphin semisubmersible offshore drilling platform. Now fully upgraded, the Blackford Dolphin can drill for oil or gas at up to a depth of 2300 meters (7000 feet). GS-Hydro delivered and installed all related non-welded piping on the platform, with a maximum working pressure of 300 bars.

Semi-submersible offshore drilling platform

The various subsystems included piping for the derrick, the ring main hydraulics, the blowout preventer BOP-system for oil testing, water-tight doors, riser guides, hose cooling, propulsion and hydraulic valves. The Blackford Dolphin platform was upgraded in the Netherlands by a globally operating offshore and marine customer, Keppel Verolme. This was the first project where GS-Hydro employed an onsite project administrator to manage purchase orders and invoicing on a daily basis – with highly satisfactory results.

In this complex project the customer required all the skills and services GS-Hydro offers, in addition to piping and connector materials. GS-Hydro’s global subsidiaries co-operated on implementation, supplying engineering, prefabrication, installation, testing, flushing and full documentation services for the piping systems. In spring 2009, the Blackford Dolphin platform was off the coast of the Republic of Ghana in Africa, drilling the deepwater Hyedua wells. GS-Hydro piping is enabling the platform to drill to a total depth of nearly 4 kilometers in a water depth exceeding 1.2 kilometers.

GS-Hydro success factors

GS-Hydro earned the contract based on its track record of successfully executing turnkey projects in the past. Keppel Verolme had certain prerequisites for the piping system that GS-Hydro was able to comply with, reliable and cost efficient system being the main targets. Non-welded systems provide superior cleanliness, which requires less maintenance and thus reduced repair costs. A reliable system can only be achieved through non-welded technology, which minimizes the risks for any potential operational problems. Already the installation of the system benefits cost efficiency. Through an easy and fast installation, valuable time onsite is minimized and prefabrication provides further flexibility. This entire offshore project lasted one and half years.
