ACE Winch Solution for DolWin Topside Float-over

ACE Winches said it has mobilized and installed a winch package for use on the jacket installation and float-over of the DolWin Topside platform, one of the world’s largest high voltage direct current (HVDC) converter platforms, generating enough power to provide approximately 1 million households with clean energy. Measuring 100m in length, 70m wide, standing 90m and weighing approximately 15000te, the platform is located in the German Bight of the North Sea.   ACE Winches supplied a winch solution which was used in conjunction with the jacket installation and float-over of the topside

Most recently, he spent ten years at Oceaneering where he delivered numerous international projects. Matthew was also the originator

Kraken Invests in German Subsea Components Firm

Kraken Sonar Inc. said it has acquired a minority interest in ENITECH Subsea GmbH, renamed Kraken Power GmbH, a provider of specialized deep sea components for underwater robotics based in Rostock, Germany.   Kraken Power GmbH, led by Dr. Carl Thiede, has been working on pressure tolerant technology and products for the subsea market for the past 10 years and is a specialist in deep-sea components for autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs). Pressure tolerant components are electronic components or assemblies that can operate satisfactorily under high pressure

Using a new method to distinguish fresh water from oil or salt water, scientists are exploring beneath the continental shelf off New England to look for large pockets of trapped fresh water. This water may be continually filling from groundwater flowing from land or, alternatively, may have been left behind by ice-age glaciers. (Image: Eric S. Taylor, WHOI Graphic Services)

Fresh Water below the Seafloor?

places many people wouldn’t expect: under the ocean. By some estimates, nearly 120,000 cubic miles of fresh water lies buried beneath the seafloor—more water than the sun evaporates from the Earth’s surface each year.   These subsea reservoirs could someday be tapped like vast offshore wells to provide additional freshwater resources to an increasingly water-scarce planet, say Rob Evans and Dan Lizarralde, scientists at Woods Hole Oceanographic Institution.   Evans and Lizarralde have been investigating what they think may be big pockets of fresh water sitting right off

Topaz Resolve Goes to Work in the Mediterranean

International offshore support vessel company Topaz Energy and Marine said its multipurpose supply vessel (MPSV) Topaz Resolve has commenced a charter in support of geophysical and geotechnical survey operations in the Mediterranean Sea for a European oil major.  Topaz Resolve is operating from Limassol, Cyprus for an initial period of one month. The vessel is a multi-functional ROV, dive and survey vessel and is equipped for deep and shallow water operations, in DP2 or by 4-point mooring. The 50m vessel, which was built in late 2015, is equipped with a 25 metric ton offshore subsea crane.

Noble Drillship Gets a DP Upgrade

Offshore drilling contractor Noble Corporation plc has selected acoustically-aided inertial navigation technology from Sonardyne Inc., Houston, for its ultra-deep water drillship Noble Globetrotter I. The Marksman DP-INS system is being used to provide a high integrity, independent subsea position reference for the vessel’s GE DP3 dynamic positioning (DP) system as it drills exploration wells in water depths up to 10,000 feet.   Built in 2011, the Noble Globetrotter I is significantly smaller than a conventional drillship but has the same operational capacity. The reduction in size has

The conference, which took place for the sixteenth time, offered information on advanced IT applications for the lifecycle of ships and offshore structures.    Topics such as autonomous maritime systems, virtual reality and augmented reality, Yards 4.0 and big data, among others, were discussed by the participants. As in previous years, DNV GL was a main sponsor of this event.

Deep-sea LED Strobe Uses High-potential Driver

The Dragonfish deep-sea LED strobe light was designed by Arctic Rays, LLC for imaging applications on AUVs and other underwater vehicles or platforms. Currently in use o AUVs such as the Remus 100, 600 and 6000, Dragonfish LED strobe lights offer compact size, high brightness (30,000 lumens at 5ms, 42,000 lumens at 200µs) and low current draw (550 mA at 24Vdc), suited for AUV-based still photography, where payload size and power budget are critical. Drive electronics, thermal protection and intelligent microprocessor control are integral in the Dragonfish’s small 1ATM, 6,000m-rated

'Above-normal' Hurricane Season Forecasted

U.S. weather forecasters on Thursday predicted more tropical storms in 2017 than normal for the Atlantic hurricane season, which last year brought one of the deadliest recorded storm systems that killed several hundred people.   Meteorologists with the National Oceanic and Atmospheric Administration's Climate Prediction Center said there was a 70 percent chance of seeing between 11 and 17 named tropical storms this season, which begins on June 1 and runs for six months.   "There is a potential for a lot of storm activity this year," Ben Friedman, acting NOAA administrator

Anti-Submarine Warfare: Unmanned Future

Hidden under the vast crystal blues of the Pacific, a submarine is hunted from above. A centuries-old game of cat and mouse drives the technological advancements in the ongoing race to conquer the undersea realms. Today, enhanced capability in both anti-submarine and anti-surface technology is transforming anti-submarine warfare, known as ASW.    Modern submarines are not only quieter than their ancestors, but they are also better equipped to deal with the threats that shadow them from above. For now, submarines are ahead in the race. But, with the emergence of unmanned autonomous technology
