Helge Ingstad Moved From Hanøytangen

February 27, 2019 (Google Translation) – Due to excessive swells, KNM «Helge Ingstad» is moved today from the accident site to Hanøytangen. At the new lifting site there are less swells.Today, BOA, together with Defense Materials, has chosen to change the place for raising the frigate KNM “Helge Ingstad”. The reason is that large swells are expected at the accident site, which makes the original raising plan for risky.

Initially, the frigate was to be drained and raised at the accident site, before transport to the Haakonsvern. Now KNM «Helge Ingstad» is moved to Hanøytangen on the west side of Askøy – about 15 nautical miles southeast of the accident site. There is expected to be quieter weather and less waves.

– We see that even a minor move southwards in the Hjeltefjord reduces the risk of swelling and swells considerably, says salvage manager Anders Penna of BOA, the company responsible for the planning and implementation of the actual lifting operation.

Drainage and raising will continue after the original plan when KNM “Helge Ingstad” is in place at Hanøytangen.

THAT’S HOW IT IS DONE
The altered lifting operation involves the frigate being moored to the two crane lifts “Gulliver” and “Rambiz”, so that they and KNM “Helge Ingstad” become one, interconnected unit. Tugboats will then pull the barge and frigate to Hanøytangen.

The trailer to Hanøytangen will be very slow, and the transport can take up to 24 hours. It is currently uncertain when the barge and KNM “Helge Ingstad” leave the accident site.

– But this can happen already this morning, says Penna.

MEASURES TO PREVENT OIL SPILLS
Environmental measures will be implemented, and all stakeholders are informed of an alternative raising plan.

– The slip will follow a fixed route down to Hanøytangen, Penna explains.

During the tow, the Coastal Administration will have its own boats with booms behind the tow in order to catch any oil spills. Environmental considerations will be taken care of at the new lifting site.

PUMPED OUT WATER
On the night of Wednesday, the divers attached the last four lifting chains to KNM “Helge Ingstad”. On Wednesday morning, personnel from the Navy have boarded the frigate to start the job of pumping water out of the vessel.

The personnel work both on deck and inside the frigate – among other things it is necessary to open doors and bulkheads inside the vessel to get enough water out. The personnel are also equipped with GoPro cameras that should document how it looks on board. The material must then be handed over to the police and the Accident Investigation Board.
