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

R/V Nanuq Joins U. of Alaska Fleet

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 which is the highest rating possible further proving the ability of the vessel to keep station in difficult conditions.The vessels

on a real-time basis at the worksite, then it’s going to be more efficient and, of course, more cost effective.What evolution or improvement to ROVs – the vehicle, control elements, or accessories – would you most like to see?It’s a balance between hydraulic and electric propulsion systems. We will see electric manipulators coming into play, reducing the reliance on hydraulic systems. ROVs today still require some heavy-duty pumping and intervention capabilities, so that’s the challenge between getting the all-electric systems vs. hydraulic systems. Today, for example,

Meet PoBo: Floating Platform for Disaster Relief

."The PoBo is a modularly configurable floating device,” said Sascha Wahlster, head of civil activities for GDELS-Bridge Systems.  “It can be used to assemble heavy-duty transport, working, diving and recovery platforms or bridges.”“By means of specially developed propulsion systems and supported by drone based underwater sensors, safe, semi-autonomous driving in flooded and unmapped areas will be made possible,” said Wahlster.The PoBo will be developed to be ergonomically friendly, and will have a mobile virtual reality system to conduct fast and cost-effective training

grant fund where we can help supply grants to support R&D projects.It's fascinating.  We’re seeing such a diverse range of really interesting solutions.  We have around 150-160 companies in the pipeline now and it ranges from wave energy products to hybrid drive electric propulsion systems. We have people looking at tendering for offshore wind, boat landings, hydrographic survey solutions and autonomous vessels.  If we can get 100 companies being more R&D focused within the next two years on top of what we are already doing, it will make a huge difference to the industry

Several critical sensor systems also were replaced, providing upgraded scientific capabilities and increased reliability."Besides extending the vessel's useful life at an attractive cost, this mid-life refit updates the propulsion systems with the newest in marine technology," said Tim Schnoor, the program officer overseeing ONR's research vessel program. "This means better diesel-electric generation and distribution systems, stronger compliance with environmental requirements, and reduced obsolescence of various
