The American Bureau of Shipping (ABS) has announced it will class the first-of-its-kind Arctic Containment System (ACS), which will serve all exploration activities in the Chukchi and Beaufort seas offshore Alaska. The ACS will be deployed in June 2012.
ABS explains that a modular oil containment system will be installed on the deck of the non self-propelled ice-strengthened barge following its conversion to a floating offshore installation The dedicated barge will remain unmanned and on standby until deployed. Then, assisted by a tugboat, its trained crew will be able to respond to an oil spill incident in the exploration areas in a matter of days.
Shell has plans to drill up to six exploration wells off the coast of Alaska, later this year and has contracted with Superior Energy, the operator of the ACS, for the containment system to be available during the summer drilling season. The containment system would be able to mitigate spillage in the time it takes to drill an intervention well.
The oil giant’s Arctic drilling plans have been facing strong opposition from environmental activists. Today, twenty Greenpeace activists boarded two icebreakers leased by Shell from Finland’s Arctia Offshore. Shell has leased the vessels to support its upcoming drilling operations offshore Alaska.

Unique Maritime Group, one of the world’s leading integrated turnkey subsea and offshore solution providers, announced today the introduction of the Light Weight Taut Wire MK 15 B to their rental pool inventory.
The Light Weight Taut Wire Mk 15B is a position-reference system used extensively with Dynamic Positioning of vessels, which is designed to provide accurate data of a surface vessel’s movement with respect to the position of a depressor weight on the sea floor.
Harry Gandhi, CEO of Unique Maritime Group commented on the addition “We are happy to introduce this Cost-effective, Well-proven and reliable technology to our customers with an operational water depth up to 300 m”.
The Light Weight Taut Wire Mk 15B is a position reference system designed for use in deck-mounted port or starboard position on surface vessels. A wire is maintained at a constant tension by means of a depressor weight on the sea-bed and a pneumatic and electric servo-assisted “mooring” system. Any movement of the vessel will cause the tensioned wire to deviate from its initial inclination. This movement activates potentiometers mounted in the gimbal (sensor) head and produces changes of analogue signals directly proportional to the deviation in inclination, which is interfaced to the Dynamic Positioning of the vessel.
