Lost tree puts rig offline

摘要

A Seadrill-connected rig working for Wintershall Dea offshore Norway is set to be offline for weeks after an equipment failure on the unit resulted in production equipment slipping to the seabed. Seadrill offshoot Northern Offshore said last week that the semi-submersible West Mira had suffered an "operational incident" on 19 March while working on the Nova field for the German operator. "During the process of lowering production equipment to the well location in the Nova field, the rig experienced equipment failure resulting in the production equipment descending to the seabed," Northern Offshore said.
