DUTCH SAFETY BOARD REPORT: LESSONS LEARNED AFTER LOSS OF CONTAINERS FROM MSC ZOE
The Ports, Customs and Free Zone Corporation in cooperation with Dubai Maritime City Authority have launched the Marine Agency to oversee wooden dhow ships and regulate all their activities while they are in Dubai waters.
Cockwells Modern & Classic Boatbuilding has restored a historic WWII vessel which helped rescue more than 336,000 allied soldiers trapped in France.
A Belfast consortium led by Artemis Technologies, a spin-off from the America’s Cup sailing team, Artemis Racing, has won a £33m UK government grant to develop zero emissions ferries.
Corrosion has emerged as the arch- enemy of the exhaust gas cleaning systems as the uptake of the technology rose with the entrance into force of the IMO 2020 sulphur cap.
The Dutch Safety Board has published an investigation report into the loss of containers from the MSC Zoe in 2019, sharing valuable lessons learned on the shipping routes that pass the Wadden Islands to the north of the Netherlands. The report stressed that minimizing the risks of container loss in the area requires an integrated approach by the container shipping sector, the IMO and the Dutch government.
Probable causes The extreme forces acting on the ship, the containers and the
lashing systems as a result of specific conditions on this shipping route were the primary cause of the loss of containers.
Findings on shipping routes Above the Wadden Islands there are two internationally designated shipping routes, a northern and a southern route. The investigation by the Dutch Safety Board has revealed that a combination of a number of phenomena means that on both the southern and northern shipping routes, there is a risk of loss of containers.
In storm-force northwesterly wind, vessels are confronted with high athwartships waves. As a consequence, large, wide container ships make extreme rolling movements. On the relatively shallow southern shipping route, there is also a risk of seabed contact (grounding) due to the combination of vertical and horizontal ship movements. Waves can slam against the ship, and seawater travelling at high speed along the side of the ship can be forced upwards against the containers. These phenomena, individually and in combination, cause extreme forces to act on the ship, the containers and the lashing systems used to retain the containers. As a consequence, containers can break free and be washed overboard.
Conclusions – For container ships, no specific guidelines or requirements are imposed on the choice of northern or southern shipping route above the Wadden Islands. Managing the risks of loss of containers on the shipping routes above the Wadden Islands currently depends on the situational decision-making on the ship if risks actually arise. This is a vulnerable situation, given that the crew has no insight in the forces and accelerations acting on containers. Also information on wave periods and wave direction is lacking in NAVTEX-messages, which is essential information for the purpose of assessing risks as a result of roll motion.
The 2019 USCG Flag State Control Domestic Annual Report shows that compared to 2018 the number of vessel inspections increased by 1,423 and the average number of deficiencies identified per inspection increased from 1.26 to 1.48.
The COVID-19 crisis has painfully demonstrated the heterogeneous landscape that currently exists across ports worldwide.
– In managing the risks on the shipping routes above the Wadden Islands, the shipping sector has not yet established any link between the undesirability of damage to nature values (in particular the Wadden area) and the polluting consequences of the loss of containers.
– The development of ever larger container ships is leading to a greater risk of loss of containers both in terms of probability and scale of the effects of such an incident. The economies of scale towards ever larger container ships have not resulted in a revised inventory or evaluation of the risks of loss of containers from these ships.
