Six new electric tugboats, including the groundbreaking Volta 1, have arrived in the Port of Antwerp-Bruges, with t e Volta 1, Europe’s first fully electric RSD tugboat, serving as the poster child for the port’s ambition to achieve climate neutrality by 2050.The electric tugboat Volta 1 is a European first. With a bollard pull of 70 tons and powerful batteries that can fully recharge in just two hours via a 1.5 MW charging station, this tugboat is completely emission-free. In addition to the Volta 1, five diesel-powered tugboats also arrived in Antwerp today.

It was never going to be realistic to expect treated ballast water to have zero viable organisms on discharge.The G8 guidelines that define the type approval process for ballast water treatment systems were initially agreed at the IMO before any systems had actually been developed.The IMO had already been working on the issue of invasive species being transferred around the world in ballast water for a couple of decades. It was on the radar back in the 1970s. At MEPC 31 in 1991…

Hamburg-based GEFO Gesellschaft für Oeltransporte mbH had an oil and product tanker from its fleet of 148 serviced and modernized at the Strela Shiprepair Yard in Stralsund for the first time. The 99 x 14 meter oil and product tanker Brahms was docked at Strela Shiprepair's premises in the Volkswerft Maritime Industrial and Commercial Park at the end of May.Brahms, which has a cargo volume of 4178 tons, was scheduled for the so-called intermediate class, meaning that extensive maintenance work had to be carried out in the shortest possible time during its stay at the shipyard.

GEA is supporting the shipping industry on this path to sustainability with new products to reduce emissions of NOx, SOx, particulate matter and soot, and new biofuel separators and solutions for the treatment of process water in exhaust gas recirculation (EGR).GEA biofuel separatorBy using biofuels such as hydrotreated vegetable oil (HVO) and fatty acid methyl ester (FAME) as an alternative for diesel engines, greenhouse gas and sulphur emissions can be reduced. However, effective fuel treatment is essential to ensure peak performance and avoid costly engine wear.
