Abstract

The invention is related to an energy system for supply of power to a Mobile Offshore Drilling Unit. The energy system comprises: - a first storage and supply device, - a second storage and supply device, - a remote power generation source for supplying power to the first and/or second storage and supply device via one or more electrical cables. The first storage and supply device are configured to store and provide sufficient power for one or more end-users onboard the Mobile Offshore Drilling Unit during normal operations, and wherein the second storage and supply device as a minimum is configured to store and provide sufficient power to secure a well, as an emergency preparedness, in case of a combined situation of a well control incident and loss of the remote power generation source. The invention is also related to a Mobile Offshore Drilling Unit and a method thereof.
