The Zeebrugge port authority and POM West-Flanders launched a study to investigate whether or not it is technically and financially beneficial to install onshore power supply facilities on the quays and on ships. The study was executed by the Ingenium bureau, who selected the ships that call on Zeebrugge regularly and stay in our port for longer periods of time. For 25% of the calls in Zeebrugge, the study concluded positively. This is about 10%of the ships in Port of Zeebrugge. The international regulations for sulphur emission control places restrictions on sea vessels in the North Sea and in the European ports. This stimulates ports, terminal operators and shipping lines worldwide to implement the needed technology.
