New Surveillance Technology to Detect Dark Ships in the Arctic | Hellenic Shipping News Worldwide

New Surveillance Technology to Detect Dark Ships in the Arctic A new surveillance technology developed by the maritime analytics and data leader, GateHouse Maritime, in collaboration with the Technical University of Denmark will help the Danish Defence monitor the Arctic Ocean. The technology is built to identify illegal ships without or turned off Automatic Identification System (AIS) transponders or so-called dark ships. The Arctic spans 14 million km2. Climate change continues to impact the Arctic area and it is expected that the maritime traffic will increase significantly over the coming 10 to 20 years. With the Arctic becoming more accessible the interests in the Arctic will increase. For this and other reasons, the Arctic is increasingly important for Greenland and for Denmark.

Norden moves forward with carbon-neutral biofuel tests

Norden moves forward with carbon-neutral biofuel tests December 16, 2020, by Naida Hakirevic Danish shipping company Dampskibsselskabet Norden A/S continues its research into alternative green transport options by carrying out a third test voyage using biofuel. Henrik Røjel, Head of Fuel Efficiency and Decarbonisation joined the bulk carrier Nord Biscay as it loaded in Ust-Luga, Russia, to prepare the crew to undertake the test. “I’m working with engineers on board to practice how to collect the performance and emissions data we need from the main engine,” Røjel said. Image Courtesy: Norden The test will take place over the next few days as the 2019-built ship sails towards the Black Sea, propelled solely on the biofuel made from waste vegetable oil.
