The crew of the sunken warship KNM Helge Ingstad didn't realise they were headed toward a moving tanker until it was too late, a preliminary investigation of the collision released Thursday found.
The Accident Investigation Board Norway said the crew of the state-of-the-art naval ship, having just completed a watch change while returning from Nato exercises in the early morning hours 8 November, thought Tsakos Energy Navigation's 113,00-dwt Sola TS (built 2013) was stationary until the two ships were within 400 metres of each other.
