Vattenfall Taps Seaway 7 for HKZ Installs

of 76 monopile foundations and the laying of the inter-array cables, all led from Seaway 7’s main office in the Netherlands.The HKZ 1 & 2 wind farm is being developed by Vattenfall as the first subsidy-free wind farm in the Netherlands and is located approximately 30 km from the coast in the North Sea. Once fully operational, HKZ 1 & 2 will be capable of supplying 760 MW which will be enough to meet the electricity needs of approximately 1 million - 1.5 million households.In addition, Seaway 7 has been chosen as one of Vattenfall’s partners for the ongoing tender for the HKZ 3 &

New Subsea Wireless IP Camera Technology

Next generation subsea technology deployed for the first time in the North Sea has helped to improve safety and reduce costcfor an offshore oil and gas project, said Scotland based WFS Technologies.The firms's new cutting-edge computing and subsea wireless IP camera technology deployed on a pipeline construction project enhanced diver safety and generated significant cost savings by avoiding the need for additional subsea vessels, it said.The work was undertaken for a new subsea pipeline which was recently installed and was necessary to bypass a platform being decommissioned. As part of the final

generation specialists EC-OG said it has demonstrated the capabilities of its Subsea Power Hub (SPH) for powering subsea production equipment using battery power alone, during a recent workshop test program in Aberdeen.During the trials, supported by the Oil & Gas Technology Center (OGTC) and a North Sea operator, the SPH was used to power a commercial Subsea Control Module (SCM) and local power distribution system. By operating the SCM using lithium ion battery technology, located within EC-OG’s proprietary Energy Storage and Intelligent Energy Management System, the test confirmed the SPH&rsquo

When Pioneering Spirit made its way into the Port of Rotterdam to prepare for topsides lift work in the North Sea, the pilot used AD Navigation AS’s new pilot’s aid, the ADX XR, as their ship-independent navigation aid.In the trials, precise movement data from Silicon Sensing’s CRH02 all-silicon gyros allowed the ADX XR to deliver a highly accurate and detailed 3- to 5-minute ship course

, based on common goals, shared values and mutual trust, supported by a commercial model where collective positive performance is rewarded.”The first developments to be executed under this contract model are the Neptune operated Duva and Gjøa P1 projects in The Norwegian sector of the North Sea at a water depth of 375 meters. Both fields will be developed as fast-track subsea tiebacks to the Neptune operated Gjøa facilities. TechnipFMC has been awarded a contract, worth between $250 million and $500 million, covering the delivery and installation of subsea equipment from the wellheads

DNV GL To Perform Hywind Tampen Study

DNV GL said on Monday it is working with Equinor to undertake a third-party verification study of the Norwegian Hywind Tampen floating wind farm, expected to be the world’s first offshore wind farm powering oil platforms.Situated in the North Sea approximately 200 kilometers west of Florø, Norway, north of Gulfaks and south of Snorre, the Hywind Tampen project will consist of 11 8 MW turbines capable of meeting 35% of the annual power demand of the two oil fields, including the the five Snorre A and B, and Gullfaks A, B and C platforms. The introduction of floating offshore wind could cut

NTNU post-docs, Ph.Ds and masters students are nearing their SmallSat launch day, after which North Sea AUVs will have taken a step toward being able to relay data to scientists onshore for long periods. Both SmallSats and AUVs will have hyperspectral cameras able to detect chemicals, metals, plankton or do survey work.The California-based Prof. Rajan is a senior scientist known for planning, executing

Remote piloting technology is maturing and is currently operational in the North Sea, where we have a number of contracts. We’re piloting ROVs remotely from our mission support center in Stavanger, Norway. This center has enabled us to complement ROV operations offshore with onshore operations. The same skilled pilots are working between offshore and onshore locations on

and better understanding of how marine life interacts with manmade structures is the target for the next phase of the Insite program.What to do with offshore structures is a sticky problem for oil companies, regulators and policy makers alike, as many structures are starting to cease production in the North Sea, where some fields have been producing oil and gas since the early 1970s.Regulations, which include the OSPAR (Oslo Paris convention) state that a clear seabed should be left behind, once production has ceased, with some exceptions (platforms over a certain age and weight). But, some have argued
