Bulk carrier Julietta D and oil/chemical tanker Pechora Star were in an anchorage near IJmuiden, the Netherlands, on Monday 31 January, when the bulk carrier’s anchor gave way as a result of a storm. The vessels collided resulting in damage to the Julietta D’s hull. After the collision, the Julietta D was taking on water and the eighteen crew members were evacuated by helicopter.
The ship then drifted towards the coast of Scheveningen and collided with the Hollandse Kust Zuid Beta transformer station jacket as well as one of the foundations for the wind turbines yet to be constructed.
Tugs of Boskalis and Multratug then managed to secure a tow to the vessel after which it was towed safely to Rotterdam.
