Engineering

Engineering included engineering of the complete electrical package. Special attention was paid to the DP class 3 requirement of redundancy for all important systems in order to prevent that one single failure could cause loss of position during DP operations. Another major item in engineering was the very high short circuit current levels of a 13.2MW electrical plant at 690V.

Supervision

Electrical installation was carried out under supervision of a team of EMC supervisors. Supervision is carried out in close co-operation with the yard’s team of electrical foremen.
