Schottel to Power 'Wind of Hope'

Schottel will provide a range of propulsion systems for Louis Dreyfus Armateurs's second wind farm service operation vessel (SOV) the Wind of Hope.The new walk-to-work vessel, a sister vessel to the Wind of Change SOV, is currently under construction at Cemre shipyard in Turkey and will enter service operating under a long-term contract with Ørsted.The propulsion system of the vessel designed by Salt Ship Design vessel is powered by four diesel generators, which drive the electric motors of the Schottel propulsion package. Two Schottel Rudderpropellers type SRP 430 FP, each with an

Dry ice formed by cooling exhaust gasses to -120°C is formed into Carbon Descent Vehicles that sink to depths of about 500 meters, where they penetrate the seabed, storing CO2 safely as liquid CO2 and CO2 hydrate. Image: MDC

contribute to atmospheric carbon reduction at a significantly lower cost than shore-based carbon capture. “While we support a goal of availability of zero-carbon or carbon-neutral fuels, we believe that a bridging carbon-free solution is needed, utilizing existing assets in terms of ships, propulsion systems and fuels,” said Madsen. “The decarbonICE project is intended to offer exactly that at a predicted low energy penalty well below 10 percent. However, we have no illusion that we can provide a 100 percent emissions reduction solution – even a 70-80 percent solution for deep-sea

as measurement errors associated with a hydrophone’s variable polar response - that are influenced by tidal flow, or caused by hydrophone misalignment during seabed deployment.Employing a sensitive three-axis accelerometer, Hydraq QQ1000 measures hydrophone vibration caused by proximity to propulsion systems or Scholte waves at the water/seabed interface.* These are low-frequency effects that contaminate acoustic measurement and need to be measured and accounted for.Hydraq QQ1000 also acts as a sensor for hydrodynamic pressure variation. It incorporates an accurate high-resolution pressure sensor

located under the ship’s hull in a submerged pod that can be fully rotated to deliver thrust in any direction. This propulsion system can break up ice as thick as 2.1 meters and also enables fuel consumption to be reduced by up to 20 percent compared to that of traditional shaftline marine propulsion systems.The Azipod system was first introduced in 1990 and has since been installed on more than 90 icebreaking vessels. Power ratings range from 1 MW to 22 MW, making the propulsion technology suitable for a wide range of vessels including cargo vessels, cruise ships, ferries, mega-yachts, offshore

Pacific Power Group, working closely with Armstrong, fit the vessel with a pair of Volvo Penta D6 engines that each deliver 330hp. The engines are paired with Aquamatic outdrives and Volvo hydraulic power steering.“Research vessels have very specific performance requirements and Volvo Penta propulsion systems have proven extremely capable of meeting those needs,” said Doug Schwedland, PPG’s vice president of the marine division.Along with the Volvo Penta engines, Nanuq is outfitted with side power electric bow thruster with joystick control to ensure precision maneuverability during

Offshore AUV, ROV Market to Grow 18.2%

propulsion system segment in particular accounted for the highest share of global offshore AUV and ROV market in 2016. The rising demand is credited to the factors such as versatility, simplicity in small ROV, low weight, reliability, low noise, and ease of packaging in comparison to mechanical propulsion systems, the report says.Geographically, the Middle East and Africa accounted for maximum share of 27% of global offshore AUV and ROV market, driven primarily by offshore oil and gas activities. Latin America is also expected to see strong growth, the report says.

.Ocean Evolution features enhanced station keeping capabilities, which allows it to maintain position even during extreme weather conditions. The vessel’s position is held using two tunnel thrusters and a drop down thruster in the bow along with two Azipull thrusters in the stern. Props on the propulsion systems can be turned 360⁰ and were designed to optimize dynamic positioning of the vessel. The vessel achieved an ERN station keeping reliability rating of 99.99.99.99 which is the highest rating possible further proving the ability of the vessel to keep station in difficult conditions.The vessels
