Netherlands: Hull Vane for the GRONINGEN

Netherlands: Hull Vane for the GRONINGEN

Gepostet von | 1 Feb 2023 | , , , | 0

The first Hull Vane for the Royal Dutch Navy was delivered in Den Helder at the beginning of June 2022. This is a baffle plate to be fitted under the stern that makes ships faster and quieter, i.e. more efficient, while also improving their sea behaviour. This guide plate will be installed on the transom of the "HNLMS Groningen", one of the four 108-metre-long and, at 3,800 tonnes, frigate-sized ocean patrol vessels (OPV) of the "Holland" class, at the beginning of 2023. Development In 2015, Dutch hydrodynamics specialist Hull Vane BV, as the patent holder, calculated in a study that the guide plate could reduce the annual fuel costs for a patrol vessel by around 13 %.

Energy: New offshore solar park system

Energy: New offshore solar park system

Gepostet von | 26 Jan 2023 | , , | 0

The Dutch offshore specialist Oceans of Energy has been granted approval in principle by Bureau Veritas for the system design of an offshore solar park. It is the first offshore solar park in the world that has proven itself even in high waves. A first "solar farm" with an output of 50 KW has already been in operation in the North Sea since 2019 for testing and verification purposes. System design Instead of heavy structures anchored in the seabed above the sea surface, which are normally used for offshore technologies, the offshore solar farm system is modular and lightweight. It utilises the sea surface directly as a support - like a water lily floating on the surface of the water. To...

As reported by NDR 1 - Radio Mecklenburg-Vorpommern on 17 January 2023, another wind farm in the Baltic Sea is now supplying electricity. "Arcadis-Ost 1" is located 19 kilometres off the coast of Rügen and has been producing wind energy since last week, according to the Belgian energy company Parkwind. Construction of the foundations began last June by the Deme Group, and the first turbines were installed in November with the help of a floating crane. Ultimately, the wind farm will have 27 wind turbines and a capacity of 257 megawatts. According to Parkwind, this could theoretically supply up to 290,000 households with electricity. In the coming years, the...

Newbuilding 782 from Flensburger Schiffbau-Gesellschaft (FSG) will set off on a test voyage of several days on the North Sea and Baltic Sea after a short stay in dock, before heading for Bremerhaven. The 210-metre-long RoRo ferry will move to Dock 3 at the Lloyd Werft shipyard there for around a week so that the shipbuilders at Flensburger Schiffbau-Gesellschaft can carry out the remaining work on the ship's hull to optimise its performance data. The "MV Tennor Ocean" will then set off on a test voyage lasting several days on the North and Baltic Seas. All technical systems will be checked and nautical manoeuvres carried out in a tightly timed programme. Already tested during the voyage from Flensburg to Bremerhaven...

Expensive LNG: Command back on two ferries

Expensive LNG: Command back on two ferries

Gepostet von | 12 Jan 2023 | , , , | 0

High LNG costs are forcing Norwegian Fjord Lines, based in Egersund, to convert two LNG-powered ferries to run on traditional marine gas oil (MGO). "The energy crisis caused by the Russian invasion of Ukraine has led to exceptional volatility and significant price increases for LNG - and the price increases have been far higher than for traditional and less sustainable marine energy sources. ... This has led to a dramatic increase in energy costs for Fjord Line's two LNG-fuelled vessels, which is well above a financially sustainable level," the company explained. First LNG ferries Since last autumn...
