MTR100: Subsea Batteries
integrated battery for offshore wind applications.”Verlume’s intelligent energy management system, Axonn, can deliver a constant output of power from renewable sources to support offshore decarbonization projects and minimize energy loss from electricity generated from offshore wind.Power management system advancements are key, but Verlume’s CTO, Paul Slorach, says the company is also continually improving the energy density of its systems. Most recently, that has involved a new module design, but he is also keeping an eye on the developments in the electric vehicle market and exploring

to establish the solution in each location.First, we keep all the transformers on the MOWU itself, and we step down to the same voltage as the main switchboard voltage on the host installation in order to keep the modifications to a minimum. But obviously you will have to upgrade and modify your power management system to reflect this coexistence between the wind power generator and the gas turbine generators, but in general terms, we try to design the system and integration for minimum required modifications.You recently signed an agreement with the Norwegian oil company OKEA to potentially power its

than 100 cable repairs, mostly in Mediterranean, Black Sea and Red SeaCapable of speeds up to 15.4 knots, the newbuild will be equipped with two main azimuth propellers in the aft and two tunnel thrusters in the forward and the system will be run and monitored by Integrated Automation System and Power Management System. The power plant shall consist of four generator sets for electrical propulsion power.The vessel has three cable tanks to carry fiber optic and power cables, one of which fitted with a carousel. The remotely operated vehicle (ROV) used for cutting, inspecting and burying cables will be stored

in the best possible solution for these vessels,” says Torbørn Torkelsen, CEO at Aasen Shipping.The full Wärtsilä scope for each ship includes a Wärtsilä 26 main engine with gearbox and controlled pitch propeller (CPP), a DC switchboard, a battery pack, and a power management system. The equipment is scheduled to be delivered to the yard commencing in mid-2021.The vessels are bulk carriers fitted with excavators for loading and unloading. The excavators will be electrically powered using the battery pack, which will save fuel and be emissions-free since normally they

16 knots. Beyond this, maximum maneuverability and propulsion efficiency are provided by tunnel thrusters – two STT 3 FP (750 kW each) and one STT 5 FP (1,500 kW) – which can be demounted from above.Together with Schottel’s control partner NORIS and IHC Systems, a complete power management system was developed. This controls the mechanically driven dredging pump, PTOs and the propellers without overloading the dual-fuel engines
Fjord Orders 10 Hybrid Power Management Systems
Norway-based company Fjord Maritime has ordered 10 hybrid power management systems at Bosch Rexroth for application onboard of fish feed barges.The plug-in systems significantly reduce generator running times, cutting fuel consumption up to 60% and considerably reducing emission rates. Total cost of ownership will run down.- Smart plug-in system provides energy efficient solution for fish feed barges- Up to 80% reduction in diesel generator running times- Reduced fuel consumption and emissions- Diesels generators for new build barge can be downsizedThe containerized power management system features an
Subsea’s Future is Blowin’ in the Wind
order to make the system as smart as possible, Equinor and Masdar are developing algorithms based on multiple data sources, including weather forecasts, market prices, maintenance schedules, consumption patterns and grid services. Digitalization is a key driver, Bringsvaerd said. Batwind’s power management system becomes smarter as its fed more data, he explained, adding that the value in storage is not necessarily in the amount of energy stored, but how its optimized and better controlled.(As published in the July/August 2018 edition of Marine Technology Reporter

autonomous. Sørensen says fully autonomous tends not to be used – the discussion gets rather philosophical. How autonomy is implemented can also take different forms. Platforms can sense then act, or sense, model, plan and then act. While something like Kongsberg’s power management system for dynamic positioning has autonomy, it's not so much able to reconfigure and make deliberative choices, says Sørensen, giving an example. Similarly, an unmanned platform isn’t autonomous, it’s reactive, he says. It could be made more autonomous by introducing deliberative
Gavia AUV Gets a Sonar Upgrade
the release of the Klein sonar module, Teledyne Gavia has recently released two other upgrades to its vehicle. The upgraded Gavia battery module has more than a 20 percent increase in capacity thanks to a partnership with Teledyne Energy Systems, Inc. In addition, a high efficiency power management system was developed by Teledyne Gavia to optimize the performance of the batteries. A new and improved nozzle actuator has also been released. The new nozzle increases the volume of compensation to better deal with deep water operations and temperature variations.
