Norwegian police have named three suspects in the investigation into the collision that sank the Norwegian frigate KNM Helge Instad last November.
An employee at the local Vessel Traffic Service (VTS), an officer aboard the Ingstad, and the pilot who had the conn on the other vessel, the tanker Sola TS, are now considered suspects. No one has yet been charged in connection with the casualty.
Seven individuals were on the bridge of the Ingstad at the time of the casualty, including one U.S. Navy trainee. According to a preliminary report from the Accident Investigation Board Norway (AIBN), the frigate's bridge team members were confused by Sola TS' deck lights and incorrectly believed that the oncoming tanker was a fixed object.
Despite extensive attempts at communication between the tanker, the VTS center and the Ingstad, the Ingstad's team did not attempt to alter course until they were in extremis. The tanker's bow struck Ingstad amidships on the starboard side, suggesting a starboard-to-starboard passing attempt.
Post-accident photos show that the 140,000-ton displacement Sola TS sustained superficial damage to her starboard side anchor guard and a small hole above the waterline on her starboard bow.
The 5,000-ton displacement Ingstad suffered extensive hull damage along her starboard side, lost propulsion and steering control, experienced flooding in three compartments, and quickly drifted aground. Eight personnel were injured.
Despite salvage efforts, Ingstad sank within several days, and salvors worked through difficult Norwegian winter weather to raise her again. She was refloated in late February and taken to the port of Hanøytangen for an investigation. Based on her condition after several months under water, the Royal Norwegian Navy will determine whether to salvage surviving equipment and scrap her or to attempt a restoration. (end of excerpt)
