Mitsubishi reduces friction on ship hulls by blowing bubbles

In February last year, Mitsubishi Heavy Industries (MHI) and transport company Nippon Yusen Kaisha (NYK) announced plans to investigate the effectiveness of a system intended to reduce the frictional resistance between a vessel’s bottom and the seawater using a layer of air bubbles. Now MHI has coupled the Mitsubishi Air Lubrication System (MALS) with a high-efficiency ship hull in the conceptual design for a container ship that the company claims would offer a reduction in CO2 emissions of 35 percent compared to conventional container carrier designs.

SeaBird claimed to be world's fastest personal submarine - and it doesn't even have a motor

If the amount of personal submarine stories crossing our desks in recent years is any indication, recreational submarines are a burgeoning market. While most personal submarines, such as U-boat Worx’s offerings, employ electric motors powered by a rechargeable battery pack, US-based company AquaVenture has taken a different approach to create what it says is the fastest personal submersible available. This is because the SeaBird doesn’t pack a propulsion system of its own, but is instead towed through the water by a surface vessel. Read More

How nuclear icebreakers work - and the reversible ships that will replace them

The Arctic North end of Russia is believed to hold as much as a quarter of all the world's oil deposits - an utterly monstrous economic prize, hidden in one of the toughest and least hospitable environments on the planet. Getting to this prize, and then transporting it back to refineries, is a monolithic task that requires one of the most awe-inspiring pieces of machinery man has ever built - the nuclear icebreaker. Purpose-built to the point of being almost unseaworthy on the open waves, these goliaths smash their way through 10-foot thick ice crusts to create viable pathways for other vessels - but fascinating new technologies could mean the days of the dedicated icebreaker are numbered.

The smartphone controlled Aquabotix Hydroview underwater vehicle

Smartphones can already be used to remotely control a variety of vehicles, including flying toy helicopters and airplanes, or even starting your car. Now remotely operated underwater vehicles (ROVs) can be added to the list with New England-based company Aquabotix rolling out its Hydroview vehicle. Equipped with LED lights and a HD video camera, the vehicle transmits a live video feed to an iOS- or Android-based smartphone, tablet, or a laptop and can be remotely operated by tilting the phone or tablet or via the laptop's touchpad.

Hi-Tech Marine’s Oronero – the world's first convertible yacht tender

Yacht tenders are generally open top boats that leave their passengers exposed to the elements, but Alex Pirard Yacht Design has created a more civilized option. Laying claim to the title of the the first yacht tender in the world to feature a convertible and completely automatized hard-top, Pirard's Oronero is designed to ferry its passengers in style regardless of weather conditions.

Coral may be a vital ingredient in sunscreen pill

Researchers from King's College London have recently discovered a natural compound produced by coral that could be suitable for use in a new type of sunscreen for humans, and it may even come in a pill! As coral is generally found in shallow waters, it therefore naturally produces a type of "sunscreen" to protect itself from the sun's UV rays. It is this natural sunscreen that scientists hope to synthetically re-create for human use. Read More

Autonomous wave energy PowerBuoy device commences sea trial

Maritime surveillance and monitoring systems that require remote power at sea often rely on diesel generators that need frequent maintenance and fuel replenishment. Now New Jersey-based wave energy company Ocean Power Technologies (OPT) has commenced sea trials of an autonomous wave energy device that provides clean energy for sea-based radar and communications systems in remote ocean locations and in all wave conditions.

New aquarium designed to put jellyfish on your desk

Jellyfish are definitely fascinating creatures, that are almost hypnotizing to watch ... you could say, they’re the lava lamps of the animal kingdom. Unfortunately for aquarists, however, they also can’t be kept in a regular aquarium, as they’ll get sucked into the water filtration intakes. That’s why Duke University Biology and Environmental Science alumnus Alex Andon started experimenting with adapting regular aquaria to make them jellyfish-friendly. After having some success with selling these converted tanks online, he decided to start making them from scratch. His San Francisco company, Jellyfish Art, is now marketing them as the Desktop Jellyfish Tank. Read More

The $500 million Italian designed floating resort

As envisioned by the Italian architectural firm Giancarlo Zema Design Group (GZDG), Amphibious 1000 is a US$500 million semi-submerged resort project planned for a protected marine area on the coast of Qatar. Reflecting its name, the resort is like a large aquatic creature stretching out into the sea. Divided into two sections of land and sea, the project includes residential buildings, offices, a central marine park, floating walkways and underwater marine galleries that all form a semi-circle around the central tower, which hosts a panoramic restaurant.

Seeds inspire new artificial anti-fouling surface

With marine biofouling on ship hulls increasing drag, which results in an increase in fuel consumption and therefore cost and pollution, the search has been on for a way to prevent fouling that is better than the environmentally damaging, toxic marine paints currently used. Taking inspiration from floating seeds, scientists from the Biomimetics-Innovation-Centre (B-I-C) in Germany have developed a promising new anti-fouling surface that is toxin-free. Read More
