ABS granted two Approvals in Principle (AIPs) to Dalian Shipbuilding Industry Co., Ltd. (DSIC) for its Self-Elevating Unit Design (DSLB150), and for its Tension Leg Platform (DSTLP500) design for the offshore industry.
The Self-Elevating Unit Design is in accordance with the applicable requirements of ABS Rules for Building and Classing Mobile Offshore Drilling Units 2017, as well as with IMO Resolution A.1023 (26) “Code for the Construction and Equipment of Mobile Offshore Drilling Units, 2009”.
The unit, with primary dimensions 103.35m length, 91.80m breadth, and 10.50m depth, is equipped with a dynamic positioning system. Its large deck space stores drilling / workover modules, supporting well intervention and other drilling operations in water depths up to 150m, such as East and South China Sea.
“Novel designs that drive efficiency play a key role in the offshore sector, and ABS is working with industry to safely implement these vital advancements,” says ABS Executive Vice President for Global Offshore Ken Richardson.
The Tension Leg Platform concept is designed with four pontoons, four columns and eight tendons, suitable for operation in the water depth up to 500m, primarily in South China Sea.
“ABS and DSIC have a long relationship and have worked closely on a broad range of offshore projects, semi-submersible units, jackups and drill ships,” said Mr. Richardson. “The ABS and DSIC teams collaborated using advanced simulation technology and incorporated the latest industry standards with the objective of advancing this novel deepwater TLP hull design.”
