Danish Maritime Authority (DMA), the Danish Environmental Protection Agency and the Danish Shipowners' Association (DSA) hosted a conference where the future implementation of the Ballast Water Management Convention was on the agenda. Now, the Ballast Water Management Convention finally enters into force on 8 September 2017. Therefore, shipowners must decide how to comply with the Convention. The Convention will be implemented during a five-year period and, once it is fully implemented, almost 60,000 ships worldwide will be fitted with a ballast water management system. ”We are striving to ensure a smooth implementation of the provisions and, thus, that ships are treated in the same way all over the world. We know very well that there are still a few outstanding issues that have not yet been clarified in the IMO, but we hope that this conference will help shed light on these issues so that we can, in the future, be prepared better for the negotiations,” says Special Adviser Clea Henrichsen from the Danish Maritime Authority. DMA and DSA offered shipowners a chance of getting an update on the Convention as such, but also on the ship requirements. In addition, the attendees got an update on the negotiations in the IMO and on short sea shipping's possibilities of being granted exemptions. More or less all types of ships use ballast water to stabilise the ship. On one single voyage, a super tanker can move 100,000 m3 seawater from one port to the next. Ballast water can contain so-called invasive species, i.e. small marine animals and other organisms that are living where the ballast water is taken on board. When the ballast water is subsequently discharged into another eco-system in the ship's port of arrival, the invasive species may present a threat to the local marine environment. In order to stop the spread of invasive species, United Nations International Maritime Organization (IMO), adopted a Convention in 2014 requiring ships to clean their ballast water before discharging it into the sea. This Convention will become effective on 8 September 2017 since it has been ratified by 30 countries which, taken together, have registered 35 per cent of the world's tonnage. In order to meet the Convention requirements, shipowners must install a ballast water management system that cleans the water before it is discharged. The price of a ballast water management system depends, to a large degree, on its capacity and is between 0.2 and 2.5 million USD. The installation is complicated and time-consuming and will, in general, require the ship to be docked for several days.
