our own development.What are the prevailing technical trends driving ROV design and development today? What do you need these vehicles to do that they currently cannot do?Keeping with the theme of residency and autonomy, electric ROVs have been around for a long time, but continued advancements in electrical systems and battery technology will be an extremely important enabler allowing increased range, durability, and more complex autonomous operations – ultimately leading to a reduction in surface vessel days. If our customers can use less vessel days in the support of their field development, operations

Floating Offshore Wind Turbine Design Passes ABS Review

completed a design review of the semisubmersible, verifying compliance with the ABS Guide for Building and Classing Floating Offshore Wind Turbine Installations. The process consisted of an independent review of the hull/tower structure, coupled aeroelastic/hydrodynamic loads, safety, stability, electrical systems, equipment, piping and hydrodynamic and station keeping design. ABS determined that FEED design, as presented, met the requirements of the relevant ABS Rules and regulatory standards.

acquisition, dynamic positioning, propulsion control, navigation and vessel automation. The concept delivers the tools needed to meet the most demanding research goals combined with flexible, intelligent energy management and propulsion solutions. Kongsberg, with its sub suppliers, will provide all electrical systems, telecom systems, the propulsion motor, cables and installation as a full engineering, procurement, construction and installation (EPCI) contract for the Atair II. As the first newbuild to use Kongsberg’s Integrated Vessel Concept for research vessels, Atair II will become one of the

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
