Frigstad taps Asian shipyards for ‘all-water drilling’ semi-sub rig

Frigstad Offshore has started a tender process with shipyards in Asia to price a new generation harsh environment semi-submersible drilling rig.

The Frigstad D90 AWDTM design has been developed over the last two years by affiliate Frigstad Engineering to take advantage of latest technology developments, meeting end client and environmental requirements of the future, the company said.

The rig has been designed to be versatile and used for “all water drilling,” both in harsh and benign environments and in water depths ranging from 350 to 14,000 feet.

Harald Frigstad, Chairman and Owner of Frigstad Group, said: “We have seen an increased demand among oil companies for larger and more efficient drilling units. The recent downturn has pushed the industry to make great advances within technology development. We have worked closely with major vendors and end users to incorporate this new technology into the Frigstad D90 AWDTM design which will provide our clients with unmatched capabilities and reduced well costs.”

The recent downturn has pushed the industry to make great advances within technology development.

Frigstad Offshore said it would initially price the rig fully equipped with a full dual activity hydraulic drilling package with 2 x 1,500 short tons hoisting capacity, riser for 14,000 feet of water depth, managed pressure drilling facilities and ready for 20K BOP system.

The final equipment selection will however be subject to commercial evaluations and client requirements, the company said.

The Frigstad D90 AWDTM is the third generation of the Frigstad D90TM design which has been used to construct three drilling units since 2006. “Scarabeo 9,” the first generation of the Frigstad D90TM design, was delivered to Saipem in 2011 and has operated since then in Cuba, West Africa and Black Sea.

The Frigstad Group had ordered another two larger versions of the Frigstad D90TM (second generation) jointly with Chinese investors in 2012.

Frigstad Group exited from this investment in late 2016 and the first unit, named “Bluewhale 1,” has recently completed its first drilling campaign successfully in the South China Sea.
