There is substantial pressure for the offshore wind industry to decarbonize maintenance vessels because, once operational, they are the largest source of CO2 emissions for offshore wind farms. This presentation describes a marinized offshore charging solution designed for wind farm maintenance vessels to enable their transition to electrical propulsion by providing in-field charging.

This presentation will review an offshore charging solution backed by a major shipping company and designed to eliminate offshore vessel emissions and facilitate clean offshore charging across the maritime sector.

This presentation describes an innovative battery charging solution for offshore use on board vessels working in offshore wind. In March 2024, the solution was tested in full scale in the North Sea by the SOV Rem Power, demonstrating that it is fully feasible to charge large battery-powered vessels in an open-water environment. The presentation will present the findings and experiences from the tests, the challenges and how they were solved, as well as the supporting activities of the project.

Liberty Lines operates a fleet of 30 high-speed passenger craft, providing a fast and reliable ferry service for more than three million passengers annually between mainland Italy, Croatia, Slovenia and the Sicilian islands of Egadi, Pantelleria, Pelagie and Ustica, and in the UNESCO World Heritage-listed Aeolian islands. In 2021, Liberty Lines embarked on a plan to renew its entire fleet of high-speed ferries while aiming to minimize the environmental impact of its operations. The operations demand the carrying of 250 passengers per ferry at a cruising speed of at least 28kts. Some of the longer crossings are nearly 100 nautical miles, and therefore propulsion solutions based on pure batteries or hydrogen were concluded to be not technically feasible. Liberty Lines contracted for 12 new vessels, the first to obtain RINA Green Plus classification. They will navigate in fully electric mode near ports and will then be able to recharge their batteries in the open sea. During long periods of stopover, the ships will use cold ironing to recharge the batteries and keep all the onboard services active to help lower the CO2 footprint. This presentation will provide a more detailed overview of this exciting project.

This presentation will provide a case study of the first commercial ferry fueled by liquid hydrogen and powered by the only fuel cell module with type approval from DNV and Lloyd’s Register. The ferry is already sailing in Norway, and more ships, including the first hydrogen inland vessel, will launch in early 2024. However, the industry is taking action to meet its decarbonization targets – not only on water but also at ports. So, in addition to sea operations, industry is also paying increasing attention to emissions produced by ships at berth and from port handling equipment. In this presentation you will learn about zero-emission fuel cell solutions and experiences.

This presentation will offer a case study of a 20m zero-emission fishing vessel for a French maritime school in Corsica making use of hydrogen fuel cells.

This presentation is of the integration of a hydrogen system for electric power generation (propulsion + hotel load). It covers the storage and distribution of a hydrogen power module using two case studies. The first is a hybrid 28m CTV for windfarm offshore service, reviewing the profile of use, consumption, etc. The second is a full H2 multiservice workboat vessel with the regulations and norms applied. A comparison with battery and conventional full diesel CTV versions will be offered.

It is estimated that 150+ SOVs will be required in Europe by 2050, representing 1.05mT of CO2 emissions each year and a potential financial liability of US$2.5m per vessel over its lifespan. Following the award of UK government ZEVI (Zero Emission Vessel and Infrastructure competition) funding, a consortium of partners has been formed to develop the world's first electric service operation vessel (eSOV), with a methanol range extender – dual-fuel hybrid. This vessel has the potential for 100% battery operation, equating to a true net zero operation.

The emissions profile and electrification promise for in-shore vessels in the 30-50 feet range are often overlooked. Smaller operators often find it difficult to understand the costs and likely benefits. Glas Ocean Electric has collaborated with BAE to create a solution to simplify the transition from diesel to hybrid electric on vessels under 50 feet. This presentation offers a case study of the impacts on fuel usage, cost-to-operate, emissions and operator well-being on a 30-foot Cape Island-style fishing boat. It goes on to explore the possible application for a hybrid system on a day of lobster fishing and discusses the application of findings in the broader aspect of the many, often unregulated, small watercraft used for in-shore and near-shore fishing.

This presentation will offer two examples of how digital twin technology has been used by two leading companies to drive innovation in the marine industry. It will explain the fundamentals of the technique and go on to present two case studies to provide practical examples.
