The UK’s Marine Accident Investigation Branch (MAIB) has opened a formal investigation after the Liberia-flagged cargo ship Baltic Klipper lost 16 refrigerated containers in rough weather while approaching Portsmouth on December 6. The containers went overboard around 6:00 p.m. local time about three nautical miles east of the Isle of Wight as the vessel rolled heavily while maneuvering to take on a pilot, with early findings indicating some boxes may not have been properly secured for arrival. The incident temporarily closed the Solent deep-water channel due to the risk posed by partially submerged containers and disrupted traffic to local ports. Since then, 13 containers have washed ashore along the West Sussex coast—at locations including Selsey, Bognor Regis, and Pagham Harbour—while three remain missing. Although the cargo was non-hazardous (primarily bananas, plantains, avocados, and empties), spilled contents and polystyrene insulation have scattered across beaches and into residential areas, prompting a multi-agency cleanup led by local councils and contractor Ambipar, alongside HM Coastguard searches and ongoing safety cordons. MAIB will examine cargo-securing practices ahead of port entry and the environmental impacts, with the aim of issuing recommendations to prevent similar losses.
