“We are moving autonomous technologies into vehicles that have always been "remotely operated" or even manned to realize more efficiency and capability.  We are really blurring the lines between "ROV" and "AUV" and minimizing the technical difference between manned and unmanned. ”

Ørsted Tapped for Connecticut Offshore Wind Farm

Ørsted US Offshore Wind and President of Ørsted North America, said, “Offshore wind will bring long-term economic and environmental benefits to Connecticut, attract related industry and supply chain investments to the state, and support Connecticut’s transition to renewable energy sources.”Revolution Wind is part of the Deepwater Wind portfolio which Ørsted acquired in October 2018. Deepwater Wind proposed the 100MW Revolution Wind project prior to the company’s acquisition.The selection follows the approval in December by Connecticut regulators of a 20-year

.“To improve OBN survey efficiency and reduce costs, a number of surveys worldwide have been acquired using simultaneous sources. For this to be applied offshore Brazil will require either a change in the current environmental concerns regarding the proximity of seismic sources or alternative energy sources to be employed,” said Midenet. “While there have been some promising developments in this area recently, these are far from being operationally proven and thus the goal of reducing OBN costs to encourage wider application and uptake will take some time unless the environmental concerns

Roadmap for Renewable Energy

These projects could help to drive a global shift in the power grid, which may see an increasing number of homes and businesses make fuller use of renewable energy sources – thereby reducing their carbon footprints.

Tidal turbine ballast for fixed offshore tidal turbines

Tidal Turbines: Is Better Ballast the Answer?

Tidal turbine ballast might be the answer in the search for reliable and economical solutions   Alternative and in particular marine renewable energy sources have recently become very popular due to all natural disasters caused by the severe climate changes and the high levels of carbon dioxide in the atmosphere. Wind and sun possess high energy potential, but their outcome remains quite unpredictable, consequently unreliable and expensive. Opposed to that ocean power is based on natural regularities as ebb and flow tides and can be planned and controlled. This is also the reason why many big

Submarine Power Cables Protection

Submarine power cables are largely deployed in various offshore renewable energy sources such as wind, wave and tidal installations to transfer power to shore, but also in oil and gas platforms and ocean science observatories. They ensure the power supply to remote areas and by connecting regional electrical transmissions enable global energy trading.   The growing importance of the marine renewable energy sector and the word’s focus on environmental issues have made submarine power cables an infrastructure of critical importance. Most efficient and reliable installation and protection

in North America.” The 79,350 acre site, secured by Statoil in a federal auction in December 2016, has the potential to generate up to 1GW of offshore wind power for New York City and Long Island, according to Statoil, making it a key part of New York State’s plan to deploy renewable energy sources to meet the state’s electricity needs. New York’s Clean Energy Standard mandates an increase in the share of renewables in its energy mix to 50 percent by 2030.  As part of that effort, Governor Andrew Cuomo recently called for the development of up to 2.4 gigawatts of offshore

consumers.”   Statoil noted that there have been significant cost reductions in both the onshore and bottom fixed offshore wind sectors in recent years. Floating wind is expected to follow a similar downward trajectory over the next decade, making it cost competitive with other renewable energy sources.   Rummelhoff said, “Statoil has an ambition to reduce the costs of energy from the Hywind floating wind farm to €40-60 €/MWh by 2030. Knowing that up to 80 percent of the offshore wind resources are in deep waters (+60 meters) where traditional bottom fixed installations

.   The wind power sector is at a critical juncture as the subsidies that have cradled it since its inception in the early 1990s, and underpinned its business model, disappear as politicians enact a long-planned push to make the industry more commercially viable and able to compete with other energy sources.   The countries that form the hub of the European offshore wind industry - Denmark, Germany, the Netherlands and Britain - are looking to gradually phase out the handouts over the next decade. This will end a crucial source of revenue for operators; in tenders concluded as recently as

The team at Seabin Project are currently using 12 volt submersible water pumps, which have the option to use alternative and cleaner energy sources. This may be using solar, wave or wind power technology depending on the geographical location and current technologies available. Seabin's global pilot programme will be launched in April 2017 with the presentation and installation of the latest prototype (V5 Hybrid) in different locations

However, the longer term impact on the offshore wind and marine energy sectors will be affected not just by the specific impact on the cost of producing energy from these sectors, but more importantly by the comparative impact versus other energy sources, which are competitors.”   “Again, it is difficult to assess what this overall effect will be,” Younger continues. “In the construction phase of offshore wind developments around 50-80% of spending is typically on imported goods and services which could be significantly
