Remote surveying techniques are on the rise

New technologies such as drones, climbers and robot arms are rapidly entering the marine survey and inspection arena. And, in turn, major classification societies are embracing the so-called Remote Inspection Techniques (RIT) for their class surveys. If you are looking for the reasons why, it is easy to answer – safer and less intrusive surveys!

Without requiring confined space entry, RITs are considerably less expensive than other methods. Likewise, they’re far safer than traditional methods of inspection that involve sending inspectors/surveyors into unsafe conditions. Analytically, the pros of RITs in conjunction with class surveys are as follows:
– improve efficiency of inspection techniques

New technology aims to reduce underwater radiated noise generated by ships’ propeller cavitation

While PressurePores are suitable for all types of vessel, they are particularly suitable for naval vessels, fishing fleets, offshore vessels and cruise ships operating in sensitive environments.
While PressurePores are suitable for all types of vessel, they are particularly suitable for naval vessels, fishing fleets, offshore vessels and cruise ships operating in sensitive environments.

A new technology aimed at reducing the underwater radiated noise (URN) generated by ships’ propeller cavitation has been developed by Strathclyde University and Oscar Propulsion.

The patented Oscar PressurePores system reduces propeller tip vortex cavitation by applying a small number of strategically bored holes in the propeller blades.

The addition of these pressure-relieving holes now allows ships to operate with a more silent propeller with a minimum of compromise on its efficiency or having to slow steam. Reducing cavitation also reduces its associated erosive effect.

Oceanco’s Bravo Eugenia receives new Yacht Club of Monaco award

Bravo Eugenia, Oceanco’s first LIFE-designed yacht, developed in collaboration with Lateral Naval Architects.

Oceanco’s recently delivered 109-meter motoryacht, Bravo Eugenia, won the accolade in the category Technology and Innovation at the Yacht Club of Monaco’s awards.

This newly conceived award is based on the Yacht Club of Monaco’s fundamental values and criteria, which include Naval Etiquette, Preservation of the Ocean and its biodiversity, and Technological Innovation.

Bravo Eugenia, Oceanco’s first LIFE-designed yacht, developed in collaboration with Lateral Naval Architects, is characterised by its Lengthened waterline, Innovative layout, Fuel-efficient hull design and integration of Ecologically conscious technologies.

The LIFE Design not only adds a slender elegance to the yacht, but also leads to a reduction in the overall demand for propulsion power. As a result, the engine room is condensed to a single tier – a rarity in large yachts. This affords additional room for lifestyle areas – particularly on the lower deck, where space is usually restricted.

The future of fish farming vessels is here now in the form of a fully electric workboat

‘Astrid Helene’ is a fully electric salmon farm workboat designed and built by Grovfjord Mekaniske Verksted, Norway. Owner/ operator Northern Lights Salmon saves the planet from up to 90t CO2 and 900kg of NOx particles annually – the average emission of a diesel powered fish-farm workboat.

There are no longer any diesel fumes on deck either. For crew, the fumes could be quite annoying – particularly if the wind was blowing it in their direction. Now, there is just clean air.

Fully electric work boats such as Astrid Helene will play a key role in the industry’s future: “Electric work boats are perfect for fish farming. Continue reading “The future of fish farming vessels is here now in the form of a fully electric workboat”
