Wave Buoy Measurements on a Hexapod

MARIN has recently expanded its facilities with a hexapod. This system can be used to generate forced oscillations in six degrees of freedom, either on a standalone basis or under the carriage of one of our basins. It is a useful tool to assess the efficiency of anti-roll tanks, sloshing in liquefied natural gas (LNG) tanks, safety of cruise ship swimming pools or drop tests with a free-fall lifeboat from a moving platform.   As the positioning system of the hexapod is very accurate, another useful application is the validation of measurement equipment.

New C-DRONE for Undisturbed Wave Spectrum Measurements

 During trials the correct measurement of metocean conditions is crucial for reproducibility, performance prediction and to avoid disputes between different stakeholders. MARIN believes its new C-DRONE can make it much easier to obtain accurate measurement data. MARIN has several systems in use to measure wave height and period. The most direct and accurate way to measure the wave characteristics is the use of a wave buoy. Yet, a buoy is rarely requested during trials because the retrieval process requires a separate support boat that can easily maneuver and pick up the buoy. And this is often

Optimizing the Tides

As long as the moon continues to orbit the earth, there will be energy in the tides. This reliability is just one of the many advantages of tidal energy, and as sea levels rise, it will become even more relevant as the effect of climate change becomes a reality. In the U.K. alone, the government estimates that wave and tidal combined has the potential to deliver 30 – 50GW equating to around 20 percent of the country’s current electricity needs. As investment and innovation begin to surge across the sector, Dutch-based tidal energy leader Tocardo joins with Nortek to help optimize the

Finding Monsters on the Ocean Surface

The study of extreme wave events in the ocean has become a popular area of research in recent years. Aside from seafarers, extreme waves impact coastal communities and are of great interest to marine renewable energy companies. This is particularly prevalent in the face of coastal erosion, rising sea levels and uncertainty in how the wave climate will change in a warming world. However, much of the current research is based on modeling and experiments. Extreme wave events – including storm waves, rogue waves, storm surges and tsunamis – are rare, and as such are difficult to observe and

Research Vessels: The Fleet is In

A wave of new and innovative research vessels are set to help scientists enhance their understanding of the oceans. MTR profiles several of these ships currently in designe and construction across the globe.   RRS Sir David Attenborough The U.K.’s new polar research ship rose to fame when Boaty McBoatface took the internet by storm as the leading vote getter in an online naming contest. The U.K.’s Natural Environment Research Council (NERC) eventually chose to call the ship RRS Sir David Attenborough, a name better fit for a $256 million high-tech research ship (though the Boaty

Klein's Side Scan Sonar, Then and Now

at MIT and I had to do a thesis. I like to build things, but I seemed destined to work on some very theoretical project. I knew of Harold Edgerton, the famous professor, and I went into his lab and asked if he had anything interesting that I might work on. He introduced me to his world and partly to the ocean world, and I think I was hooked right from the beginning.   What kind of projects was [Edgerton] working on at the time? MK: Edgerton was famous for the development of strobe light – he’s known as “Papa Flash” – but back in the late ’50s he was introduced

GeoSphere: Mapping-while-drilling Evolution

Logging-while-drilling (LWD) technologies have evolved significantly in the past decade. Today they integrate sophisticated algorithms that take advantage of the ever-increasing technical complexity combining mechanical, electrica, and software systems that are implemented downhole. These achievements helps the users gain a better understanding of the reservoir while bring drilling into a new area of efficiency and cost savings. Marine Technology Reporter’s Correspondent in Brazil spoke to Jean Seydoux, Program Manager for Advanced Reservoir Mapping Technologies for Drilling and Measurement at

Machines Infused with AI that Fly, Swarm and Dive

Can mimicking insect behavior provide a way to map the ocean floor? Can robotic-controlled flying and diving drones be both bird-like and fish-like in the race to explore the ocean depths? As a global group of 19 semi-finalist teams in the Shell Ocean Discovery XPRIZE compete to create innovative autonomous technologies to image and chart the unknown in a cold, dark and hull-crushing undersea world at depths down to 4,000 meters, we look to the innovation that will advance our understanding of our planet.    In exploring the deep ocean, we’re seeing that new robotic approaches can
