In 2012, HEGER was asked by Keppel FELS in Brazil to assist in an extreme retrofitting of the Deepwater Drilling Exploration vessel, Noble Roger Eason. The operation took place in three phases.
The vessel was docked in the yard’s floating dock.
The vessel’s aft end and sponsons were removed.
The dock was then partially submerged on a trim, allowing the new aft section to be docked in–position, without undocking the forward end of the vessel.
The new sponsons and new cranes were then added before the vessel was undocked.
