A Norwegian naval officer stands trial on Monday accused of negligence that led to the 2018 collision between a warship he commanded and an oil tanker in which the military vessel sank. The early-morning crash between the Ingstad and the fully loaded Sola TS crude carrier near a major North Sea oil export terminal also triggered shutdowns of parts of Norway's petroleum production.
