Reviewing Sapinhoá-Lula NE BSR System

The exploration and production of deepwater pre-salt plays offshore Brazil have triggered major technological challenges. Some reservoirs are located under 2,000 meters of water and have to be drilled through another 2,000 or so meters of salt. Although exploration challenges have been daunting, production challenges are no less formidable. With a number of production and injection wells placed over the large reservoirs, the difficulty of reliably and safely bringing the oil and gas to production FPSOs have been compounded by the extreme water depths involved.In 2011 Subsea 7 was awarded a milestone

The vessel, renamed R/V Rachel Carson, underwent a drydock maintenance period at MacDuff Shipyard in Scotland and was transported to the Pacific Northwest via two cargo ships.    Since the vessel’s arrival at UW on December 28, 2017, UW has been preparing and transforming the former fisheries research vessel into a capable Local Class oceanographic research vessel. R/V Rachel Carson's first research cruise starts

Wavepiston Puts Renolit Films to the Test

With its “Film Instead of Paint” concept RENOLIT is exploring new horizons in the maritime sector, as the company now plans to enter the renewable energy market with its films. The first step has been made with the use of the flock-film RENOLIT SEAL for an innovative enterprise in Denmark, where the company Wavepiston has developed at similarly-named wave-powered energy generation project.   The idea A steel cable is stretched between two anchored buoys. Energy collectors developed by Wavepiston are attached to this cable at intervals of five to six meters. These collectors consist

ADCPs: Action in OOI's Cabled Observatory

; Sound waves propagate through the water column so echoes are returned and processed from many depths. The vertical range of this collection of measurements - called a profile of ocean current velocities - is greater for lower frequency sound waves.   Introduction Thanks to a spirited cadre of marine scientists and engineers, high-tech ocean observatories are now operational. These sites provide a continuous presence in the ocean for sustained and interactive observing. Many combine innovative infrastructure with multi-discipline marine sensors.   Installed at various depths, these observatorie

Norway's Planned Subsea Cable to UK May Be Canceled

NorthConnect, a planned private power cable between Norway and Scotland due to enter operations by 2023, could be cancelled as a result of Norway's adoption of the EU's latest energy legislation, the leader of the Norwegian parliament's energy committee said on Wednesday.   If the 2-billion-euro project is to go ahead, it would need to be transferred to state-owned grid Statnett, Espen Barth Eide also said, a day ahead of a vote in parliament regarding Norway's adoption of the EU's third energy package.   "It will have to be transferred to Statnett," Eide said. "It's

SEACON Micro WET-CON Connectors

TE Connectivity (TE) is implementing two improvements to its SEACON Micro WET-CON connectors that is designed to result in faster product turn-around and expedited delivery to customers.   • Lead-Free and RoHS Compliant – In order to meet international standards, TE Connectivity began manufacturing all Micro WET-CON connectors lead-free and Restriction of Hazardous Substances Directive (RoHS) compliant starting on March 1, 2018. Previously, customers had to special order products that met these standards.  There will be a brief transition period while old inventory is depleted

Prysmian to Order Cable Layer Newbuild

Prysmian Group announced it will invest more than €170 million ($210.3 million) in a new cable laying vessel to be delivered by the second quarter of 2020.   The group said the vessel  will support long-term growth prospects in the submarine cable installation business, strengthening its interconnection and offshore wind project execution capabilities.    According to the Prysmian Group, the vessel will offer deep water installation capabilities for depths of more than 2,000 m; increased cable loading capacity thanks to large cable rotating platforms; capability to perform

N-Sea Perfoming UXO Clearance for ScottishPower Renewables Campaign

UK and Netherlands-based subsea provider N-Sea is part-way through a multimillion dollar unexploded ordnance (UXO) clearance campaign for ScottishPower Renewables. The contract for unexploded ordnance (UXO) clearance works commenced in December 2017 and includes UXO inspection, identification and clearance on the array area and export cable route of the East Anglia ONE Offshore Windfarm, located in the southern North Sea approximately 45km southeast of Lowestoft. The workscope, which will be completed later in Spring 2018 requires a flexible multi-vessel approach in order to ensure completion in
