Work Class ROVs

An invaluable resource for the marine industry, remotely operated vehicles (ROVs) perform a multitude of tasks, from pipeline inspection to subsea construction, often equipped with an array of cameras, sonars, sensors, manipulators and other tools to go to work where divers cannot. Power and payload, ruggedness and reliability: these are crucial to the heavy class ROVs examined here in part 2 of MTR’s ROV technology series.   DOER Marine DOER’s H3000 is a midsize work class ROV. Designed for multimission use from a variety of platforms, the H3000 is well suited to underwater tasks

Hull Cleaning Robot Deployed in Rotterdam

Recently the hull of the vessel Vlieborg from Wagenborg has been cleaned in the Port of Rotterdam by Fleet Cleaner and OH Ship Cleaning. The vessel was heavily fouled with slime and algae, which were all removed from the hull and captured by the installation. The collected wastewater was carefully filtered in order to comply with environmental regulations. Since the Vlieborg was not loaded during the cleaning, a large portion of the fouled hull had to be cleaned above water. Onno Steenweg, superintendent at Wagenborg, emphasizes the importance of above water cleaning: “Because most of the

Arctic Seas a 'Dead End' for Floating Plastic

"High loads of marine plastic pollution may become prevalent in the Arctic in the future," the study said.   The study said there was "special concern" about the impact of plastic on fragile Arctic wildlife, including on the seabed where bits may eventually sink.   Northern fulmar birds on

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

Zooplankton Behavior Helps Solve a Carbon Cycle Mystery

A key piece of the carbon cycle puzzle has been solved by scientists from the National Oceanography Centre (NOC), with the discovery of the mechanism underpinning more efficient carbon transfer in low oxygen zones. This research, published in Nature Communications, suggests that the observed increase in efficiency is due to changes to zooplankton activity in low oxygen zones.   The storage of carbon in the ocean has a regulating effect on the climate and is increased by the sinking of tiny carbon-containing particles from the surface ocean. More efficient sinking in low oxygen zones has been

equipped with a UAV flight recorder, real-time system monitoring and feedback, rapid response times, and ultra-efficient flight performance. All of this is packed into a single-board hub, giving users maximum performance with minimum footprint. The team is also researching the use of Synapse in unmanned marine vehicles for its future versions.    In addition, the Agile team is working on AgilPose, an autonomous precision targeting and docking system for unmanned underwater vehicles (UUVs). AgilPose allows a vehicle to calculate its position and orientation in high precision across three axes
