Cargo Loading Errors Led to Hoegh Osaka Grounding on Bramble Bank – Incident Report
The Hoegh Osaka had no probability of surviving the Bramble Bank flip shortly after the vessel departed from the port of Southampton on January 3, 2015 with insufficient stability, based on the investigation into the ship’s itemizing, flooding and grounding on the Bramble Bank in The Solent.
The UK Marine Accident Investigation Branch launched its report on the investigation on Thursday, citing a failure to evaluate stability following cargo operations and previous to departure.
The Singapore-flagged pure automotive and truck provider (PCTC) Hoegh Osaka had simply departed the port of Southampton for Bremerhaven, Germany on Jan. 3, 2015 when it developed a big starboard record because it rounded the West Bramble buoy in The Solent, inflicting some cargo shift and leading to a breach of the hull and flooding. With the record in extra of 40 levels, the ship misplaced steering and propulsion, ultimately drifting onto the Bramble Bank.
Following the accident, all crew members have been efficiently evacuated from the ship or recovered from the encircling waters and there was no air pollution, nevertheless it took a serious salvage operation to refloat the vessel get it to secure berth in Southampton almost three weeks later.
A key discovering of the investigation was that no departure stability calculation had been carried out on completion of cargo operations and earlier than Hoegh Osaka sailed. The investigation revealed that previous to departure, the Hoegh Osaka’s routine itinerary had modified from its common loading rotation between three north-west European ports, however the cargo loading plan was not adjusted to account for the itinerary adjustments. It was additionally famous that it was most probably that the cargo shifted as a result of ship’s extreme record and was not causal to the accident.
In a assertion to the media, Steve Clinch, The Chief Inspector of Marine Accidents commented:
The MAIB’s investigation discovered that Hoegh Osaka’s stability didn’t meet the minimal worldwide necessities for ships continuing to sea. The cargo loading plan had not been adjusted for a change to the ship’s standard journey sample and the variety of autos as a consequence of be loaded based on the pre stowage plan was considerably totally different from than that of the ultimate tally. The estimated weight of cargo was additionally lower than the precise weight. Crucially, the assumed distribution of ballast on board, bore no resemblance to actuality, which resulted within the ship leaving Southampton with the next centre of gravity than regular.
Even extra troubling, the investigation means that it’s a common apply within the automotive provider business for ships to sail earlier than an correct departure stability situation has been calculated, on the belief that their stability situation is secure.
“This accident is a stark reminder of what can happen when shortcuts are taken in the interest of expediency,” provides Clinch. “It is therefore imperative that working practices adopted by the car carrier industry ensure that there is always sufficient time and that accurate data is available on completion of cargo operations to enable the stability of such vessels to be properly calculated before departure.”
As a results of the investigation, the MAIB said quite a few security classes:
- Assessing a ship has satisfactory stability for its supposed voyage on completion of cargo operations and earlier than it sails is a elementary precept of seamanship that should not be uncared for. Sufficient time should be made earlier than departure for an correct stability calculation to be accomplished.
- A loading pc is an efficient and useful gizmo for the secure operating of a ship. However, its output can solely be as correct as the knowledge entered into it.
- The grasp has final duty for the protection of his/her ship. This duty can’t be delegated to shore-based managers or charterers’ representatives.
The MAIB has additionally made suggestions to the Maritime and Coastguard Agency (2016/110), the Association of European Vehicle Logistics (2016/111) and the International Chamber of Shipping (2016/112), which search to enhance security on this sector of the transport business.
