Following the recent unveiling of the diesel-electric hybrid vessel, the SW108 Hybrid, marine engineering company Southern Wind Shipyard (SWS), Nauta Design and Farr Yacht Design have released further details of the sustainable ship.
SWS states that sustainability is now its main focus when building yachts, which it says offer a high level of autonomy and a long-range cruising performance. It claims the build approach for the SW108 was to develop a vessel that was both environmentally friendly yet deployed well-tested technology to ensure safe and reliable operation.
To this end, the SW108 Diesel Electric Hybrid propulsion system was designed to be compliant with the strictest environmental regulations (IMO Tier III) and has been produced in collaboration with a globally recognized partner in advanced, technology-led defense and aerospace hybrid solutions.
According to Norwegian ferry operator Hurtigruten Group, batteries, shore power and biofuel are at the core of a large-scale green upgrade of its entire fleet of coastal express ships. The company hopes that the result will be a 25% reduction in CO2 emissions and 80% in NOX .
In what Hurtigruten describes as one of the largest environmental upgrades in the history of European shipping, all seven of the fleet’s ships will undergo significant upgrades by 2023.
The ships will be upgraded using a combination of technologies and solutions specially adapted for each individual vessel. All the ships have already been fitted with shore-power connectivity to fully eliminate emissions when connected in port.
Manufacturer E J Bowman is to release a range of titanium heat exchangers aimed at offering a cost-effective cooling solution for the electric and hybrid marine sector.
The titanium heat exchangers are said to be suitable for an array of vessels ranging from small pleasure craft to large commercial passenger ferries and workboats. E J Bowman says the new range has been designed to offer a highly efficient titanium heat exchanger at a commercially attractive price point for a product of this quality and specification.
Within the shell is a tightly packed and extremely strong titanium tube stack that is designed to provide the largest surface area possible, to ensure maximum heat transfer efficiency.
Germany-based marine specialist Fischer Panda has announced that it has developed an underwater motor for sailing boats and smaller electric motorboats, where the focus is not on speed but on the protection of nature and emission-free, quiet operation.
It is offering two versions: a 1.7kW pod motor rated to run at 2,300rpm on a 24V supply, and a 3.8kW unit rated at 3,000rpm using 48V.
“Our motors produce practically no noise as they do not need a gearbox, and the direct drive minimizes noise and vibrations,” explained Martin Mews, head of the development department for electric drives at Fischer Panda.
The changed attitudes and new initiatives being brought about with the Biden Administration are set to radically change the face of the US maritime industry – and one of the big winners will be the electrification and hybridization of workboats, ferries and superyachts, along with other special-application marine vessels.
Firmly established in Europe, Electric & Hybrid Marine World Expo has already clocked up eight years since its inaugural staging in Amsterdam in 2014, and is now set to give rise to its new US counterpart. Instantly widely acclaimed as ‘the right time and the right place for the show’, exhibitor bookings are coming in fast and the 110,000ft2 of booth space is expected to sell out quickly.
Thyssenkrupp Steel, HKM and the Port of Rotterdam is to jointly investigate setting up an international supply chain for hydrogen. As the steel makers seek to become climate-neutral companies, they will need an ever-increasing quantity of hydrogen to produce steel without the need for coal. Traditionally, both parties have imported coal, iron ore and other raw materials via a terminal in Rotterdam using inland barges.
Looking toward a more sustainable future, the partners say they will explore hydrogen import opportunities through Rotterdam, but also though a pipeline corridor between Rotterdam and the steel companies’ sites in Duisburg, Germany.
A new hybrid, water-injection dredger named Maas has begun a program of work on the UK’s River Thames following a visit to the Port of Tilbury on April 27, 2021.
Produced and built by the Kooiman Marine Group for Van Oord, an international marine contractor, Maas uses a hybrid energy management system to reduce CO2 emissions by capturing residual heat from batteries, which is then returned to the vessel’s integrated diesel-electric propulsion system.
Alongside this, the vessel also features further emissions-reducing technology in the form of heave compensation and dynamic positioning technology, enabling operations to be pre-programmed in great detail before any work commences, enhancing Maas’s efficiency.
RS Electric Boats, a subsidiary of RS Sailing, has released its latest electric RIB (rigid inflatable boat), the Pulse 63. It employs an electric drive provided by RAD Propulsion, which uses a hubless rim drive for the propellers and is integrated into the hull of the vessel.
The 40kW motor is powered by a 46kWh lithium-ion battery supplied by Hyperdrive, which operates at 400V. This combination gives a top speed of 23kts and a range of 20 nautical miles at full speed, and 100 nautical miles at a 5kt cruise.
Longer by 50cm than the 58 (RS’s first electric RIB), the 63 is available in a variety of versions, including coach and workboat variants.
