recharging, while running a full survey payload. As a result, using Kraken batteries, Ocean Infinity can operate increased survey ranges to nearly 700 line-kilometers per deployment.Using batteries from Kraken subsidiary, Kraken Power GmbH, Ocean Infinity is seeing an increase of almost 100% in energy capacity in the same physical form factor as the original stock batteries in their Hugin AUVs. From an operational perspective this gives Ocean Infinity considerable flexibility to optimize mission plans, increase area coverage, manage weather impact, reduce launch and recovery operations, and significantly

will produce more than 8 TWh annually, which is approximately 10% of total electricity demand and 50% of the total household consumption.""Even with the limited surface of the Belgian North Sea, Belgium is the fifth producer of offshore wind worldwide. Beyond 2020, the offshore wind energy capacity in the Belgian North Sea can be further developed and doubled to at least 4,000 MW. We trust solutions will be found allowing an adequate and timely grid connection for this second round,” he added

Ørsted Sees Huge Offshore Wind Potential in S Korea

completed the establishment of its Korean branch following South Korea’s announcement of a “Renewable Energy 3020 Plan,” which aims to raise the proportion of renewable energy supply to 20 percent of total power output by the year 2030.South Korea targets to have a total renewable energy capacity of 63.8 gigawatts (GW) by 2030, with 17.7 GW coming from wind power. Ørsted claimed that South Korea will particularly thrive from offshore wind power generation considering its geographical characteristics.Orsted built the world’s first offshore wind farm in 1991 and has installed

European Offshore Wind Capacity up 18%

Europe installed 2.6 GW of new offshore wind energy capacity in 2018, according to statistics released by the European Wind Energy Association, WindEurope. That translates to a 18% increase in Europe’s offshore wind capacity.According to WindEurope, 15 new offshore wind farms came on line. The UK and Germany accounted for 85% of the new capacity: 1.3 GW and 969 MW respectively.Europe now has 105 offshore wind farms across 11 countries with a total capacity of 18.5 GW. This is around 10% of the total installed wind energy capacity in Europe – the rest is onshore.The size and scale of

and diverse environmental sensors.The HUGIN SUPERIOR utilizes sophisticated positioning technology, with in mission standard navigation rated twice as effective as other AUV platforms, including current HUGIN models, the manufacturer said.The new system also comes with a 30 percent increase in energy capacity on board, notably without changing form factor or size. The extra available power can be used to extend mission endurance or maintain current levels of endurance while adding more sensors, increasing productive survey time and contributing to reduced OPEX.“The new HUGIN SUPERIOR AUV System

endurance is a critical aspect of our operational model. We invested considerable effort in understanding the current state of development in deep sea battery technology. Kraken’s pressure tolerant gel encapsulation process is simply brilliant.  Using their technology, we can increase our energy capacity by over 50 percent in the same physical form factor as our existing conventional batteries. From an operational perspective this gives us considerable flexibility to optimize mission plans, increase area coverage, manage weather impact and ultimately increase value for our customers.&rdquo

boards. It also reduced the internal wire count in the vehicle by 80%, simplifying the vehicle further. This traditional battery based performance is more than adequate for many applications. But it can be improved upon. Riptide is releasing its lithium rechargeable battery pack that doubles the energy capacity (and endurance) of the standard vehicle. Additionally, its standard alkaline battery stack was designed to accommodate multiple battery chemistries, including lithium primary and nickel-metal-hydride cells. With lithium primary cells, the standard micro-UUV can operate for over a week at speed
