ABB has won a contract covering electrical power and propulsion systems onboard a DP class 3 drillship to be conferred with ‘Enhanced Reliability’ and DYNPOS AUTRO notation from Det Norske Veritas (DNV).

The contract covers installations onboard a ‘BT-UDS’ dynamic positioned ultra-deep- water drillship ordered by
Sigma Drilling, a joint venture between Norway’s Skeie Technology and Houston-based Vantage Drilling, from STX Offshore & Ship- building.

The vessel, to be built at South Korea’s STX Jinhae yard, is scheduled for delivery in the second half of 2015. The new DYNPOS ER class notation for Enhanced Reliability from DNV recognises advances made in flexibility, redundancy and fuel-efficiency in the structuring of DP systems. The drillship will feature ABB’s most advanced protection devices; fast bus communications based on IEC 61850 standards and integrated blackout prevention functions.
