SCM functions through both SPH operating modes: battery power and battery charging.In April 2018, a previous integration trial was conducted with SEA’s precommercial SCM which they modified to work on DC power. The most recent test was conducted on the North Sea operator’s SCM, using an AC power supply from the SPH.“This is a big step forward for EC-OG, to be able to have our energy storage system successfully provide power to a commercial SCM. Demonstrating the capabilities of lithium-based batteries for powering subsea wells is a great achievement for us,” said Paul Slorach, Business

TSO could potentially cut the response time to an incident by up to 70 percent.The company has a 40-year track record, having performed more than 50 offshore repairs throughout Asia, Africa, America, Europe and the North Sea region. For instance, Nexans has been entrusted as a key partner for ensuring power supply to millions of Statnett’s end customers. With Statnett, Norwegian system operator of the energy system, Nexans today continues to develop the existing contingency agreement signed in 2011, ensuring the operational ability of their most critical high voltage cable links in the Nordic grid

Tidal Power for Seabed Oil and Gas Installations

power to subsea oil and gas installations.Rapid solutionThe most obvious immediate need for this technology is in mature oil and gas North Sea fields. Here, companies are seeking to extend field life, but are having to contend with ageing infrastructure, often in need of upgrading. This includes the power supply on which subsea installations such as Christmas trees, manifolds, sensors and other equipment depend to function. If the umbilical cable providing power and communications between the seabed installations and the surface fails, these pieces of equipment are useless.    “We saw

of The Ocean Cleanup. Conscientious structural engineering of the pods and power management are exemplary of this process. The pods, which will be subject to oceanic circumstances like storms, will have to endure severe load conditions. Considering the remote location of the system, matching a minimal power supply generated by solar panels on the one hand, with significant power consumption needs for the large number of sensors and data communication on the other hand, presented another challenge. An intelligent control system was developed to meet this requirement and ensures that vital functions, such

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

Nortek analyzed the noise spectrum present at the site and was able to modify the internal filter of the power supply to reduce the EMC noise and enable the 20-meter range.  “There are subtle electronics in the ADCP instrument, and the turbine itself is basically a giant electromagnet. This meant that initially, we couldn’t get any useful data so close to the turbines. There is also a lot
