Bosch Rexroth Launches Subsea Clamping Cylinder for BSC

.""While the rated force is being set hydraulically, a spring in the cylinder is tensioned and fixed using a safety lock unit. This allows the clamping force to be maintained over the entire operating time in a purely mechanical manner, with no need for a continuous hydraulic or electrical power supply.""Thanks to the innovative combination of flexible mechanical and hydraulic force components, the loads which act in all six degrees of freedom are automatically distributed to the Subsea Clamping Cylinders installed in the system. Each individual cylinder can withstand up to 120 tons

Photo: HIIArguably the greatest challenge today, still, lies in the ability to find and deliver increasingly robust power supply. “We anticipate that improvements in safe, reliable, long-endurance energy systems over the next few years will have significant immediate impact on UUV capabilities,” said Fotheringham. “The physical endurance of a UUV is much greater than the energy systems that currently power

create up to 40 jobs in Aberdeen over the next 12 months," EC-OG said.Halo is a modular and scalable battery storage system that operates in a demanding subsea environment. "By removing the need for undersea power cables, [the battery storage system] provides a reliable, uninterrupted power supply, located at the point of use. Halo provides a temporary, permanent or back-up deep sea electrical power solution at a fraction of the cost of alternatives," EC-OG said.The investment in EC-OG is the first that Par Equity has made since its recent partnership with the British Business Bank

Copenhagen Subsea Debuts the Gorilla ROV

will use its DP system to instantly adjust the output of its eight thrusters to maintain position relative to the seabed, meaning the operator can easily steer to the designated destination. Copenhagen Subsea said the ROV can carry up to 70 kg and it has an easy to understand payload interface with a power supply and separate fiber cable connection, dedicated to the customer specific requirement.The electrical system of the Gorilla ROV is based on industrial hardware from Japanese industrial electronics company OMRON, meaning that top to bottom Gorilla uses only industrial standard hardware components

Attached to an ROV or AUV, the system brings lights, altimeter and a pressure sensor to bear while performing its online and offline recording. A medium or large ROV or AUV is needed, one with a 12-72 VDC power supply and an ethernet link to a topside vessel.Operator Choice: variants of the Ecotone hyperspectral camera.

, with construction potentially starting in 2023."We are in a very early stage, but we've started a dialogue with oil firms to let them know about such an option," a BKK official, who did not wish to be named, said.The company was considering several options for a potential offshore power supply hub, including at Equinor's Oseberg and Wintershall Dea's Brage fields.About 80% of emissions by Norway's oil and gas sector come from the use of gas-powered turbines on offshore platforms.The project could potentially cost up to 26 billion crowns ($2.84 billion), with the first stage

New Surface Power Supply for BlueROV2

Torrance based Blue Robotics announced their newest product, the Outland Technology Power Supply for the BlueROV2, which was developed and manufactured by Outland Technology of Slidell, Louisiana. The Outland Technology Power Supply (OTPS) provides a solution to power the BlueROV2 through the tether cable, eliminating the need for batteries and allowing it to be operated indefinitely.The Outland Technology Power Supply is comprised of three components: the topside power supply unit, the ROV enclosure, and the tether, which can be purchased in 125m and 250m lengths. The ROV enclosure comes with a

by Film-Ocean after a project was affected by a fluctuating electricity supply that resulted in damage to high-value PCB boards in its ROV equipment.Mike Mackie, Operations Manager at Film-Ocean, said, “Bender’s power quality monitoring equipment alert us to spikes or troughs in the power supply voltage that can seriously affect the ROVs and cause permanent damage. Equally serious is downtime of the equipment and delays that can result from fluctuations in the power supply. If damage occurs, we can now track the cause and most importantly identify the source of the problem using Bender

more sustainable option when compared to conventional dredgers as it requires significantly less power. Equipped with a zero-emissions 16MWh battery pack, the dredger packs enough power for up to 12 hours of maintenance dredging in shallow waters. The design features fully redundant propulsion both in power supply as well as azimuthing- and bowthrusters.A power/speed prediction comparison study with a conventional trailing suction hopper dredger showed that the AUMD requires 55% less propulsion power, said Rolph Hijdra, Autonomous Vessels Research Lead at C-Job. “And by submersing the vessel we could

will support the generators with up to 1,800 kVA of power during rapid changes in electrical load such as thruster operation. This can reduce generator maintenance requirements. The battery system is also capable of providing redundant power, which can improve reliability at sea by ensuring continuous power supply.The Maersk Cape Town includes a waste heat recovery system, which is a special feature of many Maersk container vessels. This system increases overall efficiency, as it allows the batteries to charge by capturing electrical energy from heat that would otherwise have been lost out of the exhaust
