LOTOS Petrobaltic Selects Saab Seaeye Leopard ROV for Subsea Work in Polish Oil Fields
custom-configured control cabin, along with additional peripheral systems."The 3000m-rated Seaeye Leopard is the top-selling electric work vehicle of its class and the most powerful of its size in the world, enabling it to tackle large and complex work tasks previously performed by much larger hydraulic systems. At half the size of an equivalent hydraulic work vehicle, operators find the Leopard more agile and responsive and able to handle stronger currents and wave motion. It can also tolerate higher environmental temperature ranges and has a considerable acoustic advantage for survey work over hydraulic
FET to Deliver Four ROVs to DOF Subsea
to deliver four of its advanced work-class remotely operated vehicles (ROVs).The ROV order comprises of two 200HP XLX-C’s, which have recently been delivered and mobilized in late 2022, as well as two 200HP XLX Evo II’s to be delivered in Q2, 2023, FET said. The XLX Evo II’s hydraulic systems have been redesigned in line with this contract and now share a vastly increased quantity of common component parts with the XLX-C’s, providing a customer benefit for spares commonality and subsequent availability, the manufacturer added.All vehicles are being manufactured at FET&rsquo

worlds first video sounder, first continuous picture color sonar, and introduction of the first dual-propeller counter rotational bow thruster.ABT-TRAC began as Arcturus Marine Systems in 1986. Best known in the yachting industry, ABT-TRAC specializes in stabilizers, bow and stern thrusters, and hydraulic systems. Its innovations include electrically driven stabilizers that deliver hydraulic performance without hydraulic overhead.SmartCatch began in 2012 with the mission of using innovative “eyes in the net” underwater video technology to maximize commercial fishing profitability while reducing
MacArtney to Supply All-electric LARS for SMD ROV
EV work class ROV (WROV) technology, specifically for the Atom-EV.MacArtney noted its eLARS offers several environmental benefits, including reduced risk of oil spillage with zero pressurized oil over water. The system provides approximately 30% better energy efficiency than traditional hydraulic systems, and maintenance is reduced by up to 50%, with the eLARS being fully electric, the company said.Related: Rovco Invests in SMD's EV Work Class ROVRelated: MacArtney Puts First All-electric LARS into Productio

, because there’s a limited amount of energy.” There will also still be a place for crewed ROV vessels and more traditional systems, when they’re needed. Moving to all electric also has another challenge; the availability of electric tooling, as the market is dominated with hydraulic systems currently.Others are also developing electric systems – including tooling. SMD unveiled its electric vehicle (EV) WCROV early last year. Saipem is working on the Hydrone W fully electric work class ROV. Saab Seaeye is developing an all-electric full work class ROV (bigger than its Leopard
MacArtney Puts First All-Electric eLARS into Production
for more eco-friendly products, the all-electric eLARS, developed in collaboration with MacArtney customers, features a number of eco-friendly benefits. Zero pressurized oil over water significantly reduces the risk of oil spillage, and energy efficiency is improved by more than 30% compared to hydraulic systems.The new eLARS aims to provide a low cost of ownership with Plug-and-Play mobilization, maintenance work reduced by up to 50% and cost-efficient spares with minimum lead times. Designed with a high degree of integrity, the actuation of the system is based on tried and tested MacArtney technology

or untethered with a battery as a resident system or deployed from manned or unmanned vessels. And, the design aims 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

hydraulic tooling since tooling has been used, with the benefits and drawbacks that come with it. Leading the field has been Schilling Robotics, now a part of the TechnipFMC group. But, for electric vehicles to really make to most of being all-electric, they really need to be free of the burdens of hydraulic systems. Suppliers are coming up with solutions.Electric manipulationSaab Seaeye is already well versed with all-electric technology, having the broadest fleet of fully electric vehicles. It’s now also adding an electric manipulator to its toolbox.It’s a seven-function electric manipulator

The modular approach creates a benefit for hydraulic system integrators: a cost-efficient configuration of subsea hydraulic systems that matches the specific requirements of integrators, while pushing the limits of system compactness and reliability.The new range is specifically designed for subsea equipment that requires uncompromising reliability, such as in subsea installation tooling and subsea dredging systems.Photo:
