FET Inks Deal to Expand Shallow Water Ops
custom design and manufacture of winches, and launch and recovery systems. This specific model is designed to deploy, recover and store up to 3,300 meters of 25.4 mm diameter umbilical. Principal components include an A-Frame, ROV Winch with Standard Levelwind, Local Control Station and Electro-Hydraulic Power Unit on a single skid platform. Kevin Taylor, Vice president – Subsea Vehicles, said: “This contract represents a milestone, as river bed surveying is a new market for our ROVs and provides a unique opportunity to demonstrate our advanced capabilities in a challenging environment
Red Rock to Supply Cranes for New Nexans Aurora Cable Layer
;s most advanced cable layer vessels, measuring 31 meters in width and 149.9 meters in length. The updated Nexans Aurora vessel will be able to accommodate a crew of 90.In addition to the upgraded crane package from Red Rock, the delivery will include two work baskets at the stern, with common hydraulic power unit.“Red Rock is proud and excited to be part of the new Nexans CLV. A repeat order from Ulstein Verft for the new vessel shows that the custom-made Red Rock products is a good fit for an advanced vessel as this one,” said Red Rock’s Sales Manager Bjørn Mossestad.The products
Investing in Subsea Decommissioning Pays Off, Decom Engineering Finds
need for recovery to the surface.The Chopsaw, designed for operation in water depths of up to 2,000 meters and capable of cutting tubulars and other materials up to 46” diameter, completed 79 cuts on its first deployment, showcasing a 100% success rate.Powered from topside and ROV using a Hydraulic Power Unit (HPU), reeler, hot stabs and control panel, the C1-46 was joined by a smaller C1-24 unit to complete the task.Substantial time savings of almost 300% were achieved compared to using traditional diamond wire saws which typically have longer cut times and carry more risks, Decom Engineering
Sarcos and VideoRay Partner to Offer Integrated Underwater Robotic Systems
or two six-degree-of-freedom arms and performs in depths of up to one kilometer (1,000 meters) for up to two hours at a time. It can be teleoperated or operated via supervised autonomy.As the system is electronically driven, the Guardian Sea Class eliminates the added weight, size and expense of hydraulic power unit systems, lowers maintenance costs and reduces the risk of system downtime due to failure, Sarcos said.“VideoRay has designed our remotely operated vehicles to perform critical jobs in the harshest environments,” said Chris Gibson, CEO, VideoRay. “Our ROVs are a natural fit
New Contracts for Tekmar's Pipeshield, Subsea Innovation
supply bases in Damman (KSA) and Doha (Qatar).Further, Subsea Innovation has been awarded a "significant contract" for a bespoke turnkey launch and recovery (LAR) system. The scope of this contract includes the design and build of the A-frame, winch with interchangeable drum sets, hydraulic power unit (HPU) and transport frames. The contract value is approximately £2 million and is expected to be delivered by December 2023. Tekmar did not say who the client was
Bosch Rexroth Presents "Disruptive" Electric Subsea Valve Actuator
now, Bosch Rexroth says, the operators of process systems have mainly relied on hydraulic cylinders in order to open and close subsea valves with a quarter turn and a defined force. With offshore installations, for example for oil and gas production, these cylinders are supplied by a central hydraulic power unit with hydraulic pipes several kilometers in length. This solution uses a great deal of energy in order to compensate for the cumulated losses and it cannot control the movement with precision, the company explains."To date, plant engineers and operators have still relied on hydraulic cylinders
Bosch Rexroth Launches Subsea Clamping Cylinder for BSC
operation. It is designed for use for up to 25 years and no manual diving work is necessary during installation and removal. Holding operation requires no power – a hydraulic supply is only required for the initial clamping and subsequent removal. Bosch Rexroth offers an optional integrated hydraulic power unit (HPU) with electrical control systems for this purpose.""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
Remotely Operated Vehicles: Thinking out of the Box
to allow easy build-in of future technologies, such as developments in artificial intelligence.Collins says the EV will have 20% more thrust and 50% fewer moving parts, compared to hydraulic systems. It’s also 20% more compact and 20% lighter, so it can be operated from smaller vessels. A hydraulic power unit has been developed for using hydraulic tools – until all-electric tooling is developed - using the new DC thruster motors and new hydraulic control units. When electric tools do come, they will be able to be stored on the vehicle in the space freed up by removing hydraulics, instead
Aleron Acquires IMPAQ
technology.”Following the deal, Aleron Group scored its first contract in the academic sector. The newly-named entity IMPAQ-Technologies will support the British Geological Survey (BGS) with an upgrade to their RD2 remote seabed corer and rock drill. The upgraded system will use a subsea hydraulic power unit and a topside power distribution unit supplied by Aleron Subsea to increase the drilling capability of the RD2 system in deep water and areas of hard or complex geology.Aleron Group said this latest acquisition adds a new range of products and engineering capabilities to the group including
