Rocknes Successfully Parbuckled
The flexible fallpipe vessel Rocknes , which capsized in January after hitting a shallow in the Vatlestraumen strait near Bergen in Norway, has been successfully parbuckled by Smit Salvage . After two months of preparation, the vessel was pulled upright last month from its upside down position.
The salvors used the dive support/salvage vessel Smit Orca , two immersion and salvage pontoons mounted on a semi-submersible flt-top barge which together supported the pulling winches, and a supporting barge. A heavy lift cranebarge held on standby in case additional power was required to force Rocknes into its rotating movement was not called into action.
After pulling the vessel into a 130º gradient, salvors pumped water out and air into the vessel in order for it to reach its original draft depth. A special team then proceeded with the conservation of onboard instruments and machinery while the salvors sprayed parts of the vessel with anti-corrosion material. The engine room was then dewatered and conserved and the vessel rerigged.
Smit Salvage was awarded the LOF 2000 Scopic contract for the recovery of the vessel and Eide Marine Services AS from Bergen was signed as subcontractor.
