Canadian marine battery specialist Sterling PlanB says it has conclusively demonstrated that direct exposure of its battery module to a 950°C fire can be successfully managed by its unique thermal management system, which passed the A60 fire survivability test thanks to the effectiveness of its unique liquid cooling system.
The A60 test examines risks such as a fire in the machinery space adjacent to the lithium energy storage system, and the potential for a battery to contribute its considerable energy to the intensity of an existing fire. If a generator fails and causes a fire, for example, a nearby battery could go into thermal runaway (fire) due to the extremely high temperatures that would surround it, increasing the intensity of the fire and posing an explosion risk.
Japanese propeller manufacturer Nakashima Propeller and German Becker Marine Systems say they are expanding their strategic partnership after decades of cooperation. The companies state that their combined product portfolio creates a strong hydrodynamic system provider for propulsion and maneuvering of ships of all sizes for shipyards and shipping companies worldwide. As part of the strengthened partnership, Nakashima is taking a majority stake in Becker.
As its name suggests, Nakashima Propeller specializes in propellers and Becker Marine Systems in highly efficient rudders and maritime energy-saving devices. Thus, the companies can offer efficient combined systems for ships of all sizes.
NAPA, a maritime software, services and data analysis provider has announced that it will participate in the Clean Propulsion Technologies (CPT) project, a consortium led by the University of Vaasa in Finland that aims to develop radically new low-carbon solutions across global transportation sectors. NAPA states it will apply its technical expertise to further enable methods to model and optimize total energy consumption on the two-year project.
NAPA says it will use its data-driven voyage optimization solutions, NAPA Fleet Intelligence and NAPA Performance models, to develop methods to model and optimize total energy consumption on the project. The company will specifically draw on its Optimization of Total Energy Consumption Onboard (OTECO) initiative, which takes a holistic approach to energy optimization, to incorporate the novel propulsion energy arrangements developed in the CPT project.
In 2020, ferry company Stena Line said that it was continuing to reduce its total CO2 emissions and was 10 years ahead of the IMO international shipping emission reduction targets. Nevertheless, the Swedish shipping company says it is now accelerating the transition to fossil-free shipping and has presented its plan to reduce total CO2 emissions by as much as 30% by 2030.
“We are working hard to reduce our fuel consumption and emissions, while at the same time exploring tomorrow’s fuels and technologies. The main driver behind the reduction of emissions in 2020 was that we introduced three new – and up to 30% more energy-efficient – vessels on the Irish Sea.
In mid-October 2020, Spanish shipyard Astilleros Gondán was awarded a contract for the construction of 10 electric ferries for the Portuguese river passenger transport operator Transtejo – Transportes Tejo. The contract, signed last January, has now received the approval of the Portuguese Court of Auditors, and the shipyard is preparing to begin the construction of the vessels.
The 40m-long ferries will be powered by an all-electric ABB system and are based on a catamaran-type hull specifically optimized to make the most of the 2MWh batteries. With a capacity of around 540 passengers, they are expected to transport some 19 million people each year across the Tagus River in Lisbon.
Norwegian shipbuilder Vard, part of the Fincantieri group, has secured contracts for the design and construction of three service operation vessels (SOVs) for North Star Renewables in Scotland. The hybrid trio will operate on the Dogger Bank Wind Farm in the North Sea.
The SOVs were developed by Vard in close cooperation with Aberdeen-based North Star, which has secured a 10-year charter contract from Dogger Bank Wind Farm, which is currently under construction by joint-venture partners SSE Renewables, Equinor and Eni. When completed, it will be the world’s largest offshore wind farm.
North Star Renewables CEO Matthew Gordon said, “We’ve worked closely with the team at Vard for over two years on the development of our SOVs for Dogger Bank.
Finnish shipping company Meriaura Group says it has begun the preparation and design of a marine transport concept that aims to achieve 100% carbon neutrality.
It will be based on a hybrid propulsion system combining sustainably produced bio-oil and battery technology. “Meriaura Group’s goal is to launch in 2024 the first transportation concept based on renewable energy since the era of large sailing ships,” said Jussi Mälkiä, president of Meriaura Group.
Details of the propulsion system specification and the commercial operating model are still under development, but the company says that the concept is designed specifically for lake, canal and sea feeder traffic, with a plan to pilot it on Finland’s Lake Saimaa.
HAV Design and Norwegian Electric Systems have developed what they are claiming is world’s most environmentally friendly salmon transporter. The vessel was ordered by fishing company Frøy AS and will be put into operation by Salmon farming specialist Cermaq after delivery.
The new design is a further development of the well-known Havtrans vessel series, through which the company has developed its expertise in designing live fish carriers with cylindrical tanks, having delivered six such designs since 2014. This new design’s capacity is nearly doubled, with a tank volume of 6,000m3 divided between four cylindrical tanks.
The vessel has been developed in close cooperation with Frøy and Cermaq.
