New System Reduces Underwater Radiated Noise from Ship Propellers
Oscar Propulsion Limited and the University of Strathclyde have come up with a way to reduce underwater radiated noise from ship propellers.According to Oscar Propulsion, its patented PressurePores system reduces propeller tip vortex cavitation by applying a small number of strategically placed holes in the propeller blades. The addition of these pressure-relieving holes allows ships to operate with a more silent propeller.Lars Eikeland, Marine Director, Oscar Propulsion, said…
Royston Upgrades Optimum Speed EFMS Module
Diesel power specialist Royston has enhanced its Eco Speed analysis capability as part of its enginei electronic fuel management system (EFMS) to enable ship operators to identify and maintain optimum vessel speeds for efficient fuel usage across different operational modes.Devised with marine engineering specialists from Newcastle University, the Eco Speed feature enables shipping operators to manage vessel and fleet performance in the most efficient way possible without impacting on essential day to activities.Rather than being based on sea trials or test bed data…
New Tool Enables Optimum Vessel Speeds
Diesel power specialist Royston has developed a special ecospeed analysis capability as part of its enginei electronic fuel management system (EFMS) to enable ship operators to identify and maintain optimum vessel speeds for efficient fuel usage.Devised with marine engineering specialists from Newcastle University, Royston has developed a new ecospeed algorithm based on speed modeling and an analysis of vessel operating data, correlating and synchronizing information from different…
Royston Expands UK Engineering Facilities
Royston Diesel Power has doubled the size of its UK engineering facilities to support continuing global growth in its marine engine service business and new technology development. As part of a £500,000 ($676,000) investment program the company has opened an additional 15,000 sq. ft. of engineering workshop premises alongside its existing headquarters on the banks of the River Tyne. As well as increasing the company’s engine repair and maintenance capability, the new center will also provide a focus for a range of other technical support functions.
New Enginei Automatic Vessel Mode Detection
Diesel power specialist Royston has developed an advanced automode detection capability for its enginei fuel management system. The latest development is in line with the recent IMO requirement that ships over 5,000 gt should report fuel consumption to their flag states and will enable more accurate monitoring of fuel consumption and vessel emissions to be made. The enginei system uses volumetric or mass flow measurement for enhanced fuel data analysis and reporting options incorporating detailed performance data, fuel optimization rates and mission critical information.
Royston Diesel Power Wins UK Support
UK-based Royston Diesel Power has secured funding support from Innovate UK, the UK’s innovation agency, for its flagship $2.2 million Managing Energy on Marine Vessels technology program. The program aims to develop a new system for whole-vessel energy monitoring and usage, ensuring on board systems are operating at optimum performance and within environmental best practice. The project is being conducted in collaboration with Newcastle University’s School of Marine Science &…
Shipyard Worker's Tugboat Economy Research Wins Prize
UK's A&P project engineer, Sally Watson, wins Ian Telfer Prize for her paper 'Reducing fuel usage & CO2 emissions from tug boat fleets: sea trials & theoretical modeling. The Ian Telfer Prize is awarded annually for the best paper published on the subject of the environment, by a member under the age of 30. As a consequence of Sally’s research, the engine control system on the harbour tug that was tested has been modified to permit it to operate fully within the region of best fuel economy during free-running.
NavCad 2011 Has New Features
New features for the industry-standard resistance and propulsion software. HydroComp NavCad is a software tool for the prediction and analysis of vessel speed and power performance. It also provides for the selection of suitable propulsion system components – engines, gears and propellers. HydroComp has been working since late 2009 on the development of a new architecture for NavCad, and improvements to the interface. This new platform was developed with an eye to the future, and will provide a new structure for future development.
