ABS awards AIP for next-generation HD12000 drillship

HOUSTON -- ABS has awarded approval in principle (AIP) for Hyundai Heavy Industries' (HHI) next-generation HD12000 heavy duty, wide beam drillship design.

The drillship, which can accommodate a 20,000-psi blowout preventer system, has been designed in full compliance with the ABS Guide for the classification of drilling systems and other applicable ABS Rules and industry standards.

The HD12000 drillship will be capable of operating in 12,000 ft water depth with a drilling depth to 40,000 ft. Featuring an innovative hull form, the design based on HHI' s proprietary technology includes enhanced dynamic positioning capability through reduced hull resistance and thruster interaction, improved motion performance in maximum roll angle, and reduced wave resistance at field transit conditions.

Ken Richardson, ABS executive V.P., energy development, said, "Addressing greater complexity in offshore drilling, the ABS CDS Guide provides a comprehensive approach to classing offshore drilling systems and their associated support systems and equipment."

Yun-Sik Lee, senior V.P., initial design team at HHI, said, "Through the award of AIP, the design of HD12000 has been developed and verified with improved versatility and strength, increased deck space, benign motion characteristics and a reduced maintenance profile."

As part of the basic approval work scope, ABS reviewed the concept design and associated configurations interfacing with the drilling equipment and systems that will be installed on board the drillship.
