The US National Transportation Safety Board (NTSB) has blamed faulty electronics for a 2021 collision on the Mississippi River that saw a bulker slam into a barge hosting an office.

The agency said in an accident investigation report that the 52,000-dwt Jalma Topic (built 2006) lost steering after a relay on the Marfin Management-managed ship’s servo control board failed, preventing the ship’s rudder from turning.
