Barnacles are a major cause of fouling of ship hulls (Image: NOAA)

Fouling of hulls is a major problem for world shipping – for private leisure craft as well as large cargo ships – with barnacles being a major culprit. It reduces the performance of vessels and increases their fuel requirements. Medetomidine has proved effective in preventing fouling of ship bottoms and now researchers attempting to develop new, environmentally friendly methods to limit marine fouling have identified the gene that causes barnacles to react to the substance, opening up the possibility of an antifouling paint that is gentle to both barnacles and the environment.  Read More

First Littoral Combat Ship deployed

The first Littoral Combat Ship departed from Florida today for its maiden deployment, approximately two years ahead of schedule. The agile 378-foot USS Freedom (LCS 1), designed and built by a team of companies led by Lockheed Martin, is the first of 55 the U.S. Navy plans for a new class of ships designed to operate in coastal waters.  Read More

Capable of speeds of 39 nautical miles per hour, the Austal 102 will provide smooth sailin...

Shipbuilder Austal first came to Gizmag’s attention in 2005 with the launch of the world’s largest aluminum vessel, the 127 meter Benchijigua Express. The company then started building Littoral Combat Ships (LCS) for the US Navy, based on the same trimaran design. And, now, Austal is launching an even more refined version that improves sea-keeping, passenger comfort and fuel efficiency. This week, Tony Armstrong, Austal’s head of R&D, spoke exclusively to Gizmag about potentially building 20% of the US Navy fleet, how they reduced fuel consumption by a quarter, what sick bags can tell you, and much more.  Read More

15 of the world's biggest ships may now emit as much pollution as all the world's 760m car...

The Guardian has reported on new research showing that in one year, a single large container ship can emit cancer and asthma-causing pollutants equivalent to that of 50 million cars. The low grade bunker fuel used by the worlds 90,000 cargo ships contains up to 2,000 times the amount of sulfur compared to diesel fuel used in automobiles. The recent boom in the global trade of manufactured goods has also resulted in a new breed of super sized container ship which consume fuel not by the gallons, but by tons per hour, and shipping now accounts for 90% of global trade by volume.  Read More

The first U.S. Navy Littoral Combat Ship, Freedom (LCS 1), the inaugural ship in an entire...

August 13, 2008 The Littoral Combat Ship (LCS) is an entirely new class of warship designed to enable the U.S. Navy to operate in shallow waters for the many close-to-shore challenges it forsees in the coming years. The LCS is very fast, highly manoeuvrable, fully networked and quickly reconfigurable via 24 hour-installable mission modules to enable it to defeat threats such as mines, quiet diesel submarines and fast attack surface craft. There are two variants of the LCS, one a high-speed semi-planing monohull, the other a trimaran, and the first to begin trails is the monohull version from the Lockheed Martin team. Freedom (LCS 1) is currently undergoing “builder trials” on Lake Michigan, testing the ship's propulsion, communications, navigation and mission systems.  Read More

The PANGAEA Expedition.

The 35-meter two master PANGAEA is the largest and most flexible polar expedition sailboat ever built. It can navigate through tropics and rivers as easily as it can through polar regions, and will travel to five continents, including the North and South Pole.  Read More

The world’s largest and most expensive ship

It’s destined to be the world’s largest cruise ship – when launched next year, Royal Caribbean’s US$1.24 billion Project Genesis will be 1,180 feet long, and carry 5400 passengers (6,400 at a pinch). It’s the most expensive ship in history, and it’s longer, wider and taller than the largest ocean liner ever built, (Cunard’s QM II), 43 per cent larger in size than the world’s largest cruise ship, (Freedom of the Seas) and remarkably, bigger than any military ship ever built, aircraft carriers included. In a world where choice of amenities count, Project Genesis has yet another trump card – in the the center of the ship is a lush, tropical park spanning the length of a football field and lined with balcony staterooms rising six decks high with views of the gardens below and the sky above.  Read More

The US Navy's new Littoral Combat Ship, the U.S.S. Independence.

A speedy trimaran with helicopter decks, a stealthy radar profile and a healthy array of arms, the US Navy's newest Littoral Combat Ship is configurable to suit a wide array of combat missions including mine-sweeping, anti-submarine and surface combat support - and it wouldn't look the least bit out of place soaring over the credits of a Star Wars movie.  Read More

U.S. Navy orders a second Trimaran Littoral Combat Ship

December 21, 2006 The U.S. Navy has approved funding for the construction of a second General Dynamics trimaran version of Littoral Combat Ship (LCS) featuring an innovative, high-speed trimaran hull. The 127-meter surface combatant LCS is intended to operate in coastal areas of the globe, and will be fast, highly manoeuvrable and geared to supporting mine detection/elimination, anti-submarine warfare and anti-surface warfare, particularly against small surface craft. The LCS's large flight deck sits higher above the water than any U.S. Navy surface combatant and will support near-simultaneous operation of two SH-60 helicopters or multiple unmanned vehicles. The ultra-stable trimaran hull allows for flight operations in high sea conditions. In addition, the deck is suitable for landing the much-larger H-53 helicopters, should that become a future requirement. The Littoral Combat Ship will have one of the largest usable payload volumes per ton of ship displacement of any U.S. Navy surface combatant afloat today, providing the flexibility to carry out one mission while a separate mission module is in reserve.  Read More

First Littoral Combat Ship (LCS) Launched

September 26, 2006 The LCS is finally in the water, and one of the most anticipated combat ships in history has moved a step closer to deployment. There are two types of LCS (the other is the Austal-designed General Dynamics Trimaran) and the first Lockheed Martin LCS (previous stories here, here and here) was last week christened FREEDOM (LCS-1). The agile 377-foot FREEDOM is the inaugural ship in an entirely new class of U.S. Navy surface warships is designed to help the Navy defeat growing littoral, or close-to-shore, threats and provide access and dominance in coastal water battlespace. Displacing 3,000 metric tons and with a capability of reaching speeds well over 40 knots, FREEDOM will be a fast, maneuverable and networked surface combatant with operational flexibility to execute focused missions, such as mine warfare, anti-submarine warfare, surface warfare and humanitarian relief.  Read More
