Offshore Wind Cable Market to Reach $3B

more than onshore wind generation. In addition, offshore wind wires play a major part in the transport of fresh produced electricity from offshore wind farms to the coast. In addition, offshore wind cables provide stronger inclusion of renewable energy sources," said the report.Growing energy consumption across emerging economies and important public attempts to decrease damaging greenhouse gas emissions (GHG) will have a positive impact on the offshore wind cable industry's share. Low storage, restricted soil use and restricted human intervention will also improve item acceptance.Furthermore

Subsea 7's Seven Vega Launched

of the main and auxiliary reels – recessed into the main deck – offers payload flexibility.In addition, the all-electric main crane allows lift parameters to be adjusted promptly without having to manually adapt the active heave system. By having fewer components, maintenance and energy consumption are also reduced.Seven Vega has an overall length of 149 meters, a breadth of 33 meters and a Class 3 dynamic positioning system. Its reel-lay system has a 600 metric ton top tension capacity consisting of a 32 meter main reel and a 17 meter auxiliary reel with a maximum storage capacity of

Offshore Wind: California's New Gold Rush

Energy Laboratory (NREL) published a study: “Potential Offshore Wind Energy Areas in California: An Assessment of Locations, Technology, and Costs.”  One conclusion: CA’s offshore wind resource potential “corresponds to about 1.5 times the state’s electric energy consumption based on 2014 EIA figures” (italics added, EIA = the US Energy Information Administration).  The NREL study is based on six likely Pacific wind energy areas, from Crescent City, in the north, near Oregon, to Port Hueneme, just north of LA.CA’s offshore process started in earnest

of an SPRS include the potential for reducing CAPEX and OPEX associated with topside facilities, increased design flexibility, improved recovery and production rates, extended field life, reduction of flow assurance problems, debottleneck of topside water treatment constraints, reduction of energy consumption for produced water, and minimization of manned operations associated with a topside facility.The building blocks of a subsea processing system comprise the subsea separation/treatment system, subsea boosting system, subsea (re-)injection system, subsea power transmission and distribution system

New Long-range RTsys Recorder Launched

The new acoustic recording system from the RTsys company synchronizes 16 hydrophones for improved range and recording quality while still controlling cost and energy consumption. The MULTHY system will be available at the beginning of 2019.  The MULTHY recording system can hear up to four times further, thanks to its 16 acquisition channels. MULTHY has a listening surface 16 times larger than an RTsys RESEA recorder, which can only accept up to four hydrophones.MULTHY is a system made up of a recorder coupled to an acoustic antenna (linear, flat or geometric) equipped with 16 omnidirectional

closed systems. The initial trials, using Chelsea Technologies Group BACTI-Wader Pro, will aim towards a real-time alert system, that gives enough warning time for operators to respond and avoid a potential toxic bacteria outbreak."If successful, the system can also save significant costs on energy consumption. Currently Recirculating Aquaculture Systems use energy-intensive UV treatment of the water and real-time organic matter monitoring systems, such as the CTG BACTI-Wader Pro, will  give more control over the dosages required for UV treatments," reports CTG's Sam Kirby

Forum Delivers 350th RT Torque Machine

over the past 27 years, and our 350th machine provides customers with the latest software to meet the increasing demand on make-up inspection criteria. Among other improvements, our new hydraulic power unit (HPU) is capable of improved cycle efficiencies of up to 68 percent, and reduces energy consumption by up to 31 percent. We look forward to continuing our partnership with TAM in other locations, and to seeing the next 350 machines take on our customers’ challenges.”   After witnessing and signing off on the factory acceptance test for the new unit, David Neill, TAM Internationa

Copenhagen Subsea: New Milestone for Thruster Reliability

our 10,000-liter test-tank located on our premises in Copenhagen, we perform a continuous test of our thrusters. 1,000 hours of operating time comprise 42 days during which the thruster operates 24/7 at maximum power. During this period, the thruster is constantly monitored for performance and energy consumption, and any deviance is registered.    When reaching the significant milestone of 1,000 operating hours, the thruster is carefully examined and, showing no signs of exhaustion or corrosion, allowed to continue operation in the test-tank where the thruster must maintain full functionality

of large subsea modules. By reusing this technology, we have great opportunities for simplification and efficiency improvements, and for reducing carbon footprints of future gas compression systems,” explains Engebretsen. The technology also represents a significant reduction in energy consumption and carbon emissions in a lifecycle perspective on Åsgard, compared to a compression platform. This technology represents a potential for further carbon reductions through use in future subsea solutions
