Helsingborg, Sweden-headquartered \u00d6resundlinjen, a subsidiary of Denmark\u2019s Molslinjen<\/a>, is to convert its double ended car ferry MF Hamlet<\/em> to emissions-free battery operation. The 1967-built vessel, which has a capacity for 1,000 passengers and about 250 cars, operates on the three nautical mile route between Helsing\u00f8r, Denmark, and Helsingborg, Sweden.<\/p>\n The decision to upgrade the Hamlet has brought Kongsberg Maritime a major contract.<\/p>\n The primary goals of the project include achieving zero emissions, enabling full electric operation with batteries, and having mechanical propulsion redundancy. The ferry will utilize high-voltage charging in port, taking only 8-12 minutes, and low-voltage charging via gensets as an alternative.<\/p>\n Kongsberg Maritime will be responsible for rebuilding the existing thrusters to electric operation, installing new permanent magnet (PM) motors for each of the four main azimuth thrusters, each rated at 1,530 kW. Additionally, Kongsberg Maritime will provide a comprehensive energy, automation, and control package, which includes interface to the main switchboard, retrofitting the K-Chief 600 to the new K-Chief system with an energy management system, and implementing Mcon thruster control with control chairs on the double ender\u2019s two bridges.<\/p>\n Energy storage systems will be supplied by Echandia directly to the owner, while Oresund Drydocks will handle the mechanical conversion. Installation company SH-Group will produce and install deck houses and ensure that cabling is routed the right way and that the new equipment will be installed and wired.<\/p>\n The rapid conversion job is scheduled to start in November 2025 at Oresund Drydocks<\/a>, but, before that, the vessel will be visiting the yard in March during scheduled maintenance docking and preparatory work before operating the summer season and then undergoing conversion.<\/p>\n The conversion will enable emission-free operation with powerful battery packs for each of the four thruster motors. The thrusters will be powered by the electric motors, with the existing diesel engines as a backup.<\/p>\n The ferry route between Helsing\u00f8r, and Helsingborg across the northern and narrowest part of the \u00d8resund strait, though short, is one of the world\u2019s busiest international car ferry routes. With the MF Hamlet\u2019s conversion, the entire route will be fully electric.<\/p>\n Kongsberg Maritime\u2019s scope will include the conversion of the top gear on the four US 3001 controllable pitch thrusters. They will be rebuilt to have twin input, where the primary input is driven by the new electric permanent magnet motors and the secondary is connected to the existing diesel engines. The ferry will charge its batteries shoreside connecting to the existing charging robots (10.6 MW\/10.4 kV).<\/p>\n The ferry will also be prepared for installation of Kongsberg Maritime\u2019s Auto-Crossing and Auto-Docking technology to automate transit and harbor maneuvers.<\/p>\n The Hamlet will have completely new deckhouses installed on the top deck, with Kongsberg Maritime energy equipment and the Echandia batteries being key features. The two bridges will get new console layouts to improve visibility and new control chairs for the pilot and co-pilot for enhanced ergonomic operation.<\/p>\n \u201cWe have the strategic vision to electrify our entire fleet to secure the complete green transition and become carbon-neutral in 2040,\u201d said Molslinjen CEO Kristian Durhuus. \u201cHamlet <\/em>is an important step for us, and we look forward to welcoming our passengers to yet another fully electric ferry on \u00d8resundslinjen.\u201d<\/p>\n \u201cWe are proud to lead the electrification of the MF Hamlet <\/em>ferry,\u201d said Martin Kj\u00f8raas, head of aftermarket sales seaborne, integration and energy, at Kongsberg Maritime. \u201cThis project demonstrates our dedication to sustainable maritime solutions and our expertise in hybrid and electric upgrades.<\/p>\n \u201cThe continuous collaboration between \u00d6resundlinjen, the yard, and all sub-suppliers has been exceptional in the project preparation phase, and we look forward to seeing the positive impact this conversion will have on the environment and the efficiency of this busy ferry route.\u201d<\/p>\n The post Kongsberg will play key role in conversion of \u00d6resundlinjen\u2019s MF Hamlet to hybrid<\/a> appeared first on Marine Log<\/a>.<\/p>\n<\/div>\n
