Case Study: Cables in Underwater Missions

has now used the custom cable for dozens of missions, in regions as diverse as the Arctic to the tropical waters of Polynesia. It has proven ideal for the expeditions, carried out every two years since 2008. It is set to be deployed again in 2021. Near identical cables are now in use in China, Germany, India and Antarctica.We’ve learned through experience that cables used in dynamic subsea environments have to be custom designed and built for the specific harsh environments our customers encounter. The properties of synthetic strength members and outer jackets can make the difference to

said. "The other construction works are on track to complete the twin pipelines by the end of 2019."Nord Stream 2 is being built to transport gas from Russia into Europe. So far, more than 800 kilometers of pipes have been laid on the seabed for the project in line with the permits granted by Germany, Finland, Sweden and Russia. Currently there are more than 1,000 people working on some 20 vessels for the project.Pioneering Spirit installing pipeline in Swedish waters (Photo: Nord Stream 2

was admitted as a PhD candidate.Then-Director Harald Sverdrup would become a lifelong friend and mentor to Munk, who also became fast friends upon joining Scripps with Roger Revelle, a research oceanographer who had just received his doctorate.Munk became an American citizen in 1939 and when war with Germany seemed imminent, he joined the U.S. Army, serving in the 146th Field Artillery, 41st Division at Fort Lewis, Wash. Sverdrup, however, requested his recall in 1941 and Munk returned to Scripps to begin work at the new U.S. Navy Radio and Sound Laboratory in the San Diego neighborhood of Point Loma

New Submarine Cable System for Canada

mm² 69 kV three-core submarine cable system with XLPE insulation for a total of 20 km. All submarine core cables will be produced at Prysmian’s center of excellence in Montereau (France), while the cable armoring will be manufactured at Prysmian’s state-of-the-art factory in Nordenham (Germany), part of the Group after the merger with General Cable. Completion of the project is scheduled for October 2019.The first cable will run approximately for 3.5 km from the Cable Riser Station at Chocolate Cove, on the east side of Deer Island, to a Cable Riser Station at Wilson’s Beach, on

European Offshore Wind Capacity up 18%

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 offshore wind

Meet PoBo: Floating Platform for Disaster Relief

Systems won a contract to develop a multi-functional, modular floating platform known as Pontoon Boat (PoBo). The project was awarded under the Innovation Program for the Support of Diversification Strategies of Defense Companies in Civil Security Technologies, or DIVERS. DIVERS is a program launched by Germany’s Federal Ministry of Economics and Energy (BMWI), with VDI Technologiezentrum GmbH as the responsible project executing agency."The PoBo is a modularly configurable floating device,” said Sascha Wahlster, head of civil activities for GDELS-Bridge Systems.  “It can be
