EnSolve Biosystems announced that it has developed a new product called EnScrub which treats particulates and petroleum hydrocarbons from the effluent of shipboard sulfur oxides (SOx) scrubber systems. This patent-pending technology, partially funded by a Phase II National Science Foundation (NSF) grant, combines biological and physical processes to remove and destroy petroleum hydrocarbons from the aqueous effluent of SOx scrubbers. "Whereas SOx scrubber systems focus on the removal of sulfur oxides from engine emissions, harmful particulates and petroleum hydrocarbons end up in the aqueous effluent of these scrubber systems," explained Jason Caplan, president of EnSolve. "If this petroleum-tainted effluent is sent overboard, it can present an environmental and regulatory problem for the shipowner. The EnScrub system addresses these contaminants thereby reducing or eliminating the regulatory risk of discharging untreated SOx scrubber water overboard." In late 2012, EnSolve conducted efficacy testing of a prototype EnScrub System on effluent obtained from an SOx scrubber system at the Port of Long Beach, Calif. The analytical results indicated that the EnScrub system was successful in reducing more than 99 percent of the petroleum hydrocarbons from the SOx scrubber water effluent. Subsequent testing in 2013 confirmed the results of the 2012 Port of Long Beach ...

An ABB turbocharging solution enables gas and diesel engines to go from idling to full load in half the time it usually takes, thereby significantly reducing fuel consumption and greenhouse gas emissions. Fuel accounts for more than two-thirds of the operating costs of gas and diesel engines. This, and the increasingly stringent emissions regulations for the maritime, power generation, and other industries make engine efficiency the number one priority for engine builders and engine users alike. One of the tools that engine builders are using to reduce fuel consumption and greenhouse gas emissions is Valve Control Management (VCM?), ABB's variable valve train system. VCM can typically increase gas engine efficiency by more than one percentage point, and that means fuel savings of more than two percent. For a 10,000 kilowatt gas engine, this translates into about $200,000 in fuel savings annually. For a power plant with ten such engines or more, the savings are significant. Optimized at all times VCM is an intelligent valve train system that works adaptively to provide an engine with the optimal amount of air for different speeds, loads and operating conditions. This enables, among other things, the turbocharger to take the engine from idling to ...

Clipper has in-house technical management of a large part of their vessels. They believe that improved performance can be achieved through innovative thinking, enabling a dynamic fleet that lives up to its full potential. The company's Performance Management team is continuously working on fuel efficiency and energy consumption optimization. One such initiative was the bulbous bow and rudder bulb modifications made on a G-type 9,100 dwt multipurpose carrier, Clipper Galaxy. The bulbous bow (bulb) is a very important part of the hull as it can potentially reduce the hull resistance considerably, or affect the resistance in a negative way. Designing the perfect bulb is delicate and the efficiency depends on the speed and loading/draught of the vessel. In the past a bulb was usually designed and optimized to full speed and close to full load condition. However, most vessels are operated at eco-speed in part load conditions. In particular multipurpose vessels are seldom operated in full load conditions. The bulb of Clipper Galaxy was modified during dry-dock at Lixin Shipyard in Shanghai in August 2013. The existing bulb was cut off and a new bulb with a different size and shape was fitted instead. At the same time they also ...

Videotel has launched a new training course, The Practical Management and Switching of Fuels, designed to ensure that switching to low sulphur fuel when operating in Emission Control Areas (ECAs) avoids the serious operational problems that at best impair a ships performance and at worst cause major damage to engines. "In the highly competitive world today of carrying cargo, shipowners face a number of serious issues," explains Nigel Cleave, CEO of Videotel Marine International. "High fuel costs and strict emission controls directly influence the way a vessel's fuel systems and engines are operated and managed. Having a thorough understanding of the challenges presented by using heavy marine fuel oil and switching to low sulphur fuel when operating in Emission Control Areas (ECAs) is essential and this new course from Videotel addresses that need. "Since 2010, many of the busiest shipping areas of the northern hemisphere are now designated as ECAs and require a switch from high sulphur to low sulphur fuel - a process that requires very careful management." The Practical Management and Switching of Fuels is designed to provide a practical guide to what is required of bridge and engine room officers and engineers to process fuel oil from ...

Hydrex has installed  Propeller Boss Cap Fins (PBCF) on two tankers during their respective stops in Ghent and Antwerp. As a result of the underwater operation, the ships will not have to wait for their next drydock visit to start benefitting from the fuel savings the PBCF's will bring them. The Propeller Boss Cap Fins (PBCF) is a device for propeller efficiency improvement developed by Mitsui O. S. K. Lines, Ltd. The PBCF can recover energy loss of a propeller hub vortex in the propeller's backward flow. This decreases fuel consumption by 5% when operating at the same speed, or boosts speed by 2% with the same fuel consumption. The 5% energy saving effect has been verified by world research institutes including International Towing Tank Conferences (ITTC) and by owners. With the current emphasis on global environment problems, the demand for the PBCF has been continually growing and this as an energy saving device and an environment-friendly product because it realizes a 5% reduction in CO2, NOx and SOx gases emission from vessels. On-site installation prevents a long wait for fuel saving benefits The first operation was performed on a 183-meter tanker berthed in Ghent. After the team arrived at ...
