World's first car-carrying electric ferry to see use in Norway

By - January 11, 2013 2 Pictures
Presently, the Norwegian villages of Lavik and Oppedal are linked by a ferry that burns about a million liters (264,172 US gallons) of diesel a year, emitting 570 tonnes (628 tons) of carbon dioxide and 15 tonnes (16.5 tons) of nitrogen oxides. That’s about to change, however, as it’s slated to be replaced by what is claimed to be the world’s first all-electric car-carrying ferry. Developed by Siemens and Norwegian shipyard Fjellstrand, the vessel can recharge its batteries in just ten minutes. Read More

Electrolysis-based anti-biofouling system keeps hulls clean

By - December 7, 2012
Marine biofouling is the process in which organisms such as barnacles problematically colonize underwater surfaces. When it happens to the hulls of ships, the vessels become less hydrodynamic, having to burn more fuel in order to move through the water. Although hulls can be coated with paint that kills the offending organisms, that paint also releases toxic substances into the surrounding water. Now, however, scientists from Germany’s Fraunhofer Institute for Mechanics of Materials have developed a more environmentally-friendly paint, that uses electrolysis to control biofouling. Read More

Sail the mighty Amazon River onboard a 147-foot-long floating hotel

By - November 7, 2012 8 Pictures
Tour operator Aqua Expeditions is an adventure travel company that offers guests the chance to cruise the Amazon River in Peru, while staying on board a 147-foot-long (45-meter) floating hotel. Designed by Peruvian architect Jordi Puig, the M/V Aria is an intimate cruise ship that can accommodate a maximum of 32 passengers, plus crew. The unique accommodation offers a rare chance to observe the wonders of the Amazon region from an unobstructed vantage point – be it from one of the ship’s numerous outdoor decks, or from the privacy of a guest suite.

Royal Navy installs photo-realistic bridge simulator

By - October 12, 2012 7 Pictures
On-the-job training is not something you want to do with the bridge team of a frigate costing over a billion pounds, so the Royal Navy uses simulators to bring officers up to speed. The latest is a Photo-realistic warship bridge simulator installed at the Britannia Royal Naval College (BRNC), Dartmouth, England. This simulator uses computers to generate images so realistic that students often sway as the “ship” rolls, even though it’s sitting still. Read More

U.S. Navy looking at obtaining fuel from seawater

By - September 26, 2012 3 Pictures
Tell someone that you’ve invented a car that runs on water and they're liable to report you for fraud. That hasn’t stopped scientists and engineers at the U.S.. Naval Research Laboratory (NRL) who want to run warships on seawater - or at least, to turn seawater into jet fuel. This may sound like they’ve been standing too close to the ether again, but the idea is to extract carbon dioxide and hydrogen from seawater and then convert these into jet fuel by a gas-to-liquids process. If this proves practical, American naval vessels could refuel themselves at sea. Read More

Glycerol additive makes cruise ships greener

The bunker fuel used in cruise liners and freighters is some of the cheapest, crudest fuel available. It’s also among the dirtiest. Scientists from the Maine Maritime Academy and SeaChange Group LLC led by George N. Harakas, Ph.D announced at the 244th National Meeting & Exposition of the American Chemical Society that they have developed what they call "Bunker Green" fuel. This fuel uses an ingredient commonly used in food and medicine to reduce sulfur and other emissions in ocean vessels. Read More

Royal Navy’s T26 GCS next-gen warship unveiled

The U.K.’s Ministry of Defence (MOD) has unveiled its new multi-mission warship - the Type 26 Global Combat Ship (T26 GCS). Due to replace the thirteen Type 23 frigates in Britain’s Royal Navy when it enters service in after 2020, the T26 GCS has been in development by the MOD and BAE Systems since 2010 and is intended for use in combat and counter-piracy operations as well as supporting humanitarian and disaster relief work around the world.

ASV hulls would dramatically improve ship efficiency by riding on a cushion of air

By - March 6, 2012 4 Pictures
A European project is developing new Air Support Vessel (ASV) hull designs that allow watercraft to ride on a cushion of air to greatly reduce friction between the hull and the water, resulting in more hull speed for less power than conventional designs. The project is part of a EUR10,000,000 (approx. US$13,225,000) project funded in part by the European Union, the Norwegian Research Council and Innovation Norway, and Norwegian company Effect Ships International AS has recently completed tank-testing in Sweden of two ASV hull models.
