If power is lost to a DPS-controlled drill-ship’s thrusters there is a risk that the rig will drift off its position, which can potentially give rise to huge impacts and the risk of damage to the subsea equipment (Blow Out Preventer (BOP), Riser, and associated equipment). Along with such an unfortunate occurance also will come significant financial impacts; the cost of repairs, new equipment and lost day rates. Clearly, in the event of a power loss, the speed of engine re-start is of critical important.

In the design of the drill-ships’ electrical propulsion system, Maersk say that their engineers, set the engine emergency start-up time bar higher, looking for a decrease in the usual ... [More]
