Buoy Harnesses Wave Energy to Power Instruments at Sea

A new buoy from Danish company Resen Waves harnesses wave energy to provide continuous power and real time data connectivity to autonomous instruments and machinery in the oceans as a plug and play solution.   While instruments and machinery in the sea have traditionally been powered by batteries, PV or diesel generators, this typically requires regular ship operation to replace batteries or supply of fuel and maintain diesel generators. This is not always possible due to weather and can become costly, meaning power is often economized by cutting back on data transmission, which limits the

A ban on Norway's Statoil using a pioneering drilling technology in the Barents Sea was lifted after a plaintiff failed to post security in a patent dispute, a lawyer said on Thursday. A Stavanger court earlier in June upheld an injunction on the technology's use, pending payment of a 20 million Norwegian crown ($2.35 million) security by privately owned NeoDrill. NeoDrill was unable to post the security due to its "very limited economic position". But it was open to finding a commercial solution with Statoil, Kyrre Tangen Andersen, a lawyer representing NeoDrill, told Reuters in an

Marine Hazards to Subsea Cables and Pipelines

In February 1989 the RoRo vessel Vinca Gorthon ran into heavy weather and sank off the Dutch coast. She landed on an oil pipeline that was severely damaged. Although the probability of sinking on top of a pipeline is very small, the incident showed that it can happen.   Shipping traffic can represent a potential hazard to subsea pipelines in various ways, such as sinking or grounding, lost containers or an anchor hooking onto a pipeline. Over the years MARIN has contributed to the development of a method by which the burial depth of a cable or pipeline is determined on the basis of actual

US Coast Guard Tests Environmentally Friendly Buoy Moorings

buoys to direct water traffic and to protect vulnerable benthic ecosystems such as seagrass communities and coral reefs in U.S. waters. However, most buoys are currently attached to the seafloor by concrete anchors, also called sinkers, and heavy metal chains that can have a significant impact on marine life. Sinkers can damage life on the seafloor under their heavy footprint, and when the connecting chains are lax, they can scrape off seagrasses, seaweeds and corals around the sinkers as waves and wind push the buoys around.The Coast Guard has been struggling to find a solution for more than 20

InterMoor Unveils New Acoustic Release Mooring Connectors

other connectors on the market can only disengage at a portion of their load rating.The new device was designed using the proven platform of sister company SRP’s Rocksteady mooring connector and its secondary actuated release system, with a control system developed in conjunction with Teledyne Marine. The advanced control system uses military-grade, high-fidelity Teledyne Benthos acoustic modems, and implements domain key authorization, unique addressing, network relay and frequency hopping techniques, ensuring the mooring connectors are never affected by obstructions or conflicting noise.The

A Record-setting Journey to the Atacama Trench

and recovering a benthic lander named DOV Audacia (Audacity), three times to deeper than 8,000 meters, the last to a record depth of 8,081 meters deep. Using a Mocness Trawl the expedition also collected plankton at a record depth of 5,000 meters. The Atacamex 2018 expedition represent a milestone for marine science in Chile, as researchers there pursue seminal work in deep-sea exploration and research.The hadal zone is the deepest region of the ocean, from 6,000 to 11,000 meters below sea level. Their access and study is extremely difficult due to the high pressures and great difficulties of reaching

Chain-climbing Underwater Robot Passes Trials

Climbing robot with ultrasonic imaging for mooring chains inspection passes field trialsA robot designed to hook onto, and scale up and down, large mooring chains, both at subsea level and in the air – with a nondestructive testing (NDT), ultrasonic imaging system on board that scans for critical defects – has recently undergone field trials.The new climbing robot, named RIMCAW (Robotic Inspection of Mooring Chains in Air and Water), is the result of a yearlong, fast-track project that secured funding from Innovate UK, the Government agency behind finding and driving the innovations that

Shell Awards Deepwater Installation Contract in GOM

In another sign that activity in the moribund offshore sector is starting to loosen, Jumbo said that it has won the installation contract for the Shell deep-water Vito development in the US Gulf of Mexico.    The Vito development is located in the Mississippi Canyon, approximately 150 miles south of New Orleans in water depth of more than 4,000 feet.   Jumbo’s installation contract involves the initial pre-lay of the mooring system as well as the subsequent tow and hook-up of the FPS. Roddy Lafontaine, VP Offshore for Jumbo says:   "The Jumbo Offshore team is very
