A China Navigation Co (CNCo) general cargoship has been penalised in the US for failing to switch engines to low-sulphur fuel from heavy diesel when close to the Californian coast. The California Air Resources Board (ARB) said the Hong Kong owner will pay $129,500 for its 25,600–dwt Chenan (built 1992). The incident dates back to 2012, when an ARB inspector found that the ship was operating within 24 miles of the shoreline on non-compliant heavy fuel oil on 12 separate days involving four voyages between August and December from Los Angeles.
