WIN WIN: Wind Powered Oil Recovery Concept Progresses

The DNV GL-led joint industry project, WIN WIN (WINd powered Water INjection), has completed its first phase and determined that wind power could be used to power offshore water injection. The project is currently moving into its second phase, which includes refining and testing the electrical systems, and investigating possibilities for broader applications. The project consists of four partners: DNV GL, ExxonMobil and ENI Norge – all part of the first phase – and the Norwegian Research Council – a new participant for this second phase.  The first phase of the project

RV Belgica to Undergo Electrical Systems Refit

System integrator Alewijnse Marine Systems said it has won an order for an electrical systems refit aboard RV Belgica, an oceanographic research vessel owned by the Belgian state.   Prior to the assignment, Alewijnse carried out a year-long research project on a limited lifetime extension of the vessel. The refit will start in April 2016 and take several months to complete.   RV Belgica celebrated her 30th anniversary in 2014 and renovations are necessary for the ship to continue in active service for another seven years. The vessel is the subject of a maintenance agreement between the

electrical servicing and maintenance projects for various sophisticated vessels that the two companies have undertaken together. Alewijnse, a global organization with 125 years of experience in marine technology, assembled a strong team of electrical technicians to work on the wide range of electrical systems on board the Marion Dufresne II. The tasks included the overhauling of a number of electrical motors and the electrical disconnection of an A-frame. Alewijnse was also responsible for the installation, connection and pre-commissioning of a new capstan winch installation and a watertight

treated carbon steel with protective plating. As the CPT will be used almost exclusively in salt water the machine includes integrated cathodic protection. Every part on Wachs Subsea’s CPT is designed to resist corrosion and require minimal maintenance. The machine’s hydraulic and electrical systems are equipped with depth compensation for deepwater operation under extreme pressure, and each includes an advanced warning system to alert the operator if seawater infiltration is detected. While primarily developed for deepwater operations it’s worth noting that the CPT series is equally

of Liquid Robotics Oil and Gas (LROG), a joint venture with Schlumberger, about the qualities and capabilities of the Wave Glider. The Wave Gliders are in a distinctly different class of AUVs from previous gliders in that they are wave-propelled with continuous diurnal solar panel support of electrical systems. A sensor platform like the Wave Glider is capable of detecting solid data at depths where satellites data is unreliable. Sudhir explains the vision behind the design of the Wave Glider and how its development process occurred, “The Wave Glider development began out of a man’s passion

North Sea Accommodation Module Sealed with Roxtec

;Our multi cable transit seals are being used in the platform accommodation module to protect assets from serious hazards such as fire, blast and water ingress. Specifically we supplied standard and electromagnetic compatibility (EMC) stainless steel cable seals to protect the platform’s electrical systems from airborne interference.” O’Hare said for the accommodation module Roxtec was also required to supply a special sealing system for copper nickel pipes. “The copper nickel pipes are really important and are designed to be highly resistant to seawater corrosion,&rdquo

CPT series is engineered and built to ISO 9000-2008 standards. Constructed with aluminum, epoxy coated syntactic flotation, stainless steel, bronze and heat treated carbon steel with protective plating, the CPT also includes cathodic protection, all designed to resist corrosion. Hydraulic and electrical systems are equipped with depth compensation for deepwater operation under extreme pressure, and include an advanced warning system to detect seawater infiltration. Deploying the machine begins by positioning the CPT in its custom deployment frame on the seabed, in close proximity to the repair

We will enjoy working closely with graduates from AEUK to increase the number of electrical systems that can be implemented in the next submarine as well as refining the current mechanical systems.” subrace.eu uk.atlas-elektronik.com  


The New Standard in Diver Communications

of high pressure. The increased helium content which is lighter than air, changes the voice sound produced within the mouth, giving the diver a high pitched, difficult to interpret voice. Another problem with traditional analogue diver communication systems is noise interference from other electrical systems. This can cause lower than desired communication clarity, particularly as systems age and cables and connectors deteriorate. Keen to address these challenges and set new standards in diver communications, Aberdeen-based through water communication and positioning technology company Nautronix

fuel efficiency over a diverse range of tasks: diesel-electric power is often better suited for escort operations, while mechanical propulsion is used for maximum power in transit and during operations. The propulsion systems include Berg shaftlines, Caterpillar engines and generators and Techsol electrical systems. Representatives from Bourbon and CGG declined to say how much the hybrid propulsion hiked the ships’ overall cost, but they did estimate fuel savings in the range of 30-40% compared to standard vessels. Each vessel saves a few thousand dollars per day on fuel thanks to the operational
