On paper, Li-CO2 batteries could boast far superior energy density to today’s state-of-the-art battery types – but this nascent technology requires further analysis and development, writes May Chan Lithium-CO2 (Li-CO2) batteries are a relatively new type of battery that uses CO2 as the cathode and lithium as the anode to generate electrical energy. Compared to […]
Archipelago Yachts and Chartwell Marine’s catamaran concept makes a convincing case for an environmentally sound yet long-range leisure vessel, writes Stevie Knight The new Archipelago zero.63 is a methanol fuelled, 18.3m conundrum, combining a number of elements that you wouldn’t necessarily expect in a single vessel. So, how – and why – have very disparate […]
With 17kW of peak solar power at its disposal, and a wingsail designed for optimal wind capture, the new ZEN50 catamaran series is set to bypass the need for the ‘obligatory’ backup diesel genset The forecast’s for sunshine for builder ZEN Yachts, which has confirmed the pre-sale of the first four units in its solar-powered, […]
Autonomous technology meets alt-fuel readiness in SAFE Boats International’s ambitious AHSV Merlin, which has been carefully developed to conjure up cost efficiency on offshore wind farm pre-assessment missions As with offshore wind farm support vessels, it’s not unreasonable to expect research and survey vessels to ‘green up’ their operations. After all, there’s a certain irony […]
Tugboat original equipment manufacturers (OEMs) have relied on hydraulic oil-driven winches for decades, but they are now starting to embrace energy-efficient, next-generation electric winches, writes Mikael Holmberg, winch and crane segment sales manager at ABB Drives Hydraulic winch systems have been adopted by nearly 70% of vessels across the world, and they’ve stood the test […]
Following successful sea trials, the Vietnam People’s Navy is now the owner of an innovative submarine rescue vehicle developed by Forum Energy Technologies Submarines are a vital component of modern naval warfare, capable of covert and independent underwater operations for extended periods. However, when things go wrong, it’s crucial that submarine personnel are able to […]
As two long-serving members of the Armed Forces of Malta’s OPV fleet prepare for retirement, the island has welcomed a larger, modern replacement to conduct surveillance and SAR tasks in the Central Mediterranean March saw Italian shipbuilder and designer Cantiere Navale Vittoria witness the commissioning of its largest offshore patrol vessel (OPV) to date in […]
Emil Jonze, Docksta Varvet, Sweden and Dr Ronald Pelot / John Dalziel MRINA, Dalhousie University, Canada explain why the Docksta Loitering, Optionally Crewed, High Speed Rescue Vessel concept was deemed necessary, and run though the features of this innovative life-saver The following article is a slightly truncated version of presentations delivered at the World Maritime […]
Designed for optimum onboard space, and boasting state-of-the-art tech for steering and troubleshooting support, Sea Ray’s SLX 280 Outboard series looks set to make quite an impression in leisure boat circles this summer The US recreational boat market has done a convincing job of shrugging off the world’s troubles, and is attracting new participants and […]
Start-up PolyGone has developed a biomimetic, hydrophobic filter to remove typically hard-togather, sub-1mm microplastics from water – and recent trials are yielding encouraging results Recent figures suggest that our oceans currently contain around 165 million tonnes of plastic. However, even if plastic production ceased tomorrow, existing plastics would continue to break down, leaving a growing […]
Seatrec’s infiniTE autonomous float could play a vital role in timely weather forecasting, incorporating technology designed to overcome the current limitations of battery-powered floats Many valuable data sensors “are just left at sea when their batteries run out”, says Yi Chao, founder and CEO of Seatrec. For example, the Argo Programme uses around 4,000 robotic […]
A unique and patented ‘artificial gill’ breathing system is one of the eye-catching features of the forthcoming DeepSeaker – a craft designed to function as both a high-speed hydrofoil and a high-tech mini-sub Imagine a compact craft capable of shooting across the surface at high speeds on retractable hydrofoils, before plunging 50m beneath the surface […]
