SBSS successfully completed Korea power cable projectIn November 2010, S. B. Submarine Systems Co. Ltd. has successfully completed the simultaneous marine installation of the twin line power cable project between Anjwa and Whawon island in South Korea. This system will be the first of its kind in this region in terms of cable size, rated capacity and installation methodology.


The system purchaser - KEPCO, Korean Electric Power Corporation, required two 154kV cables to be laid simultaneously and fitted with specially fabricated UP Urethane protection throughout the cable laying process. The 3 core XLPE cables were manufactured by LS Cables which weighed approximately 83kg/m with an overall diameter of 203mm.

To meet the customer's requirements, S.B. Submarine Systems utilized the highly capable CS Fu Hai DP2 Cable Ship. The vessel was equipped with a specialized power cable laying spread in order to allow for the loading and laying of this large diameter power cable.

The route between Whawon and Anjwa was challenging in itself with strong side currents in excess of 3 knots and frequent storm force winds. Not only was the station keeping capabilities of the vessel key in overcoming these difficulties but the approach that the project delivery team took in terms of planning and execution was fundamental in mitigating these risks so as to ensure a successful implementation as well as supporting SBSS's philosophy of 'right first time'. Overall the actual implementation took approximately 12 days.

The success of this simultaneous installation of two 203mm diameter cables is a landmark project for SBSS in terms of project scope and engineering challenges.

Mr. Bruce Neilson-Watts, the Managing Director summarized SBSS performance in this project: "The successful installation of 2 x 154kV power cable in Korea is a testament to SBSS's marine installation capabilities."
