Mitigation of underwater noise is a hot topic, especially with the proliferation of offshore wind farm projects across Europe, the US East Coast and parts of Asia. Typically, wind turbine monopiles are driven into the seabed by large hydraulic hammers attached to the tops of the monopiles, a process that generates excessive noise. These high […]
Of all the yacht subsectors, the expedition yacht segment perhaps faces the most immediate pressure to guarantee low-to-zero-emissions operations, given the eco-sensitive areas these vessels are designed to visit. Finland-based shipbuilder and designer Deltamarin elaborates: “Customer pressure is especially strong in the more exclusive ship types – expedition ships and yachts. A lot of clients […]
A fishing and training vessel delivered to Måløy Upper Secondary School, Norway is to be upgraded with a complete hydrogen fuel cell system, to grant its occupants extended, albeit emissions-free, time on the water. Launched by Denmark’s Hvide Sande Shipyard in May this year, and delivered to its owner, Vestland County Municipality, in August, the […]
Seattle-based fishery Arctic Storm Management is replacing its 83m, 1974-built trawler Arctic Fjord with a larger newbuild of the same name – and one specifically designed to handle operations in the Bering Sea, where 45knot winds, 4m wave heights and heavy snowfall in coastal areas are not unknown. The 99m x 21m newcomer was constructed […]
Electric boatbuilder Candela reports that it has set a new world record, using its Candela C-8 hydrofoiling craft to cover a distance of 420nm within 24 hours – described by the company as “the equivalent of travelling from London to Amsterdam and back” within this timeframe. The previous record was set by a Voltari 260 […]
Oliver Rommelrath, a student at Staffordshire University, scooped the first-place prize in this year’s Superyacht UK (SYUK) Young Designer competition, hosted at the Southampton International Boat Show. The contest saw the entrants given 14 hours (spread over a day and a half) to produce a superyacht profile illustration, a general arrangement (GA) drawing and detailed […]
3D printing for marine applications is still in it nascent phase – although ambitious projects in the US, Denmark and the Netherlands are casting light on the potential for 3D-printed vessels. In October 2019, the world’s largest 3D-printed composite boat, the 3Dirigo, was assembled and launched by the Advanced Structures & Composites Center of the […]
Cycloidal (or vertical axis) propellers have, frankly, been a bit ‘niche’ – until now, writes Stevie Knight. Although their ability to change thrust direction almost instantaneously has proven very useful for tugs and ferries, their Achilles Heel has been speed. So, the most important point about ABB’s new Dynafin is that it promises to deliver […]
Washingtonian boatbuilder BRIX Marine has delivered a custom-built aluminium catamaran to Alaska-based Allen Marine Whale Watching Tours. Based on BRIX Marine’s PaxCat class, Eagle features a length of 14.6m and a 5.5m beam, and has been constructed with 5086 alloy aluminium hull skins for enhanced durability in the choppy Alaskan waters. The builder reports that […]
Lightning strikes may not get the attention bestowed on fire safety at sea, but they can inflict equally devastating damage upon vessels, personnel and offshore structures. An estimated 3-8 million+ lightning strikes occur globally each day, equating to a frequency of 44-100 strikes per second (these can be viewed in real time at the site […]
A new green energy consortium launched in Singapore hopes to answer the Port Authority of Singapore’s (MPA’s) call for electric harbour craft operations within its waters. The consortium is being led by Singaporean company Cyan Renewables, which has stated its intention to own and operate a fleet of modern offshore wind farm support vessels worth […]
Yanmar Power Technology (YPT) has commercially launched a customisable maritime hydrogen fuel cell system, specifically targeting vessels on coastal routes “where hydrogen refuelling is relatively accessible”, the company states. YPT tells Ship & Boat International: “At this time, we are looking at applying the technology to sightseeing ships or similar with a capacity of about […]
