AEGIR-Marine Wins NK Class Type Approval

AEGIR-Marine assigned with an NK Class Type Approval. The newly certified seal assembly will be available for customers worldwide as of today. They are an addition to our Type Approval from several other major classification societies.For the NK Class Approval AEGIR-Marine performed a 2,000 hours endurance test in its state-of-the-art and certified R&D Test Center. A 1,000 hours of test runs were at extreme RPM and another 1,000 hours were at low to average RPM. Also, the conditions a seal has to withstand were simulated as realistically as possible.

Panama Certifies Japanese Scrubber System

For almost a year Kawasaki Kisen Kaisha, Ltd. ("K" Line), Mitsubishi Heavy Industries, Ltd. (MHI) and Mitsubishi Kakoki Kaisha, Ltd. (MKK) have been performing tests aboard an operational ship of a newly-developed "Hybrid SOx Scrubber System" for removing sulfur oxides (SOx) from the exhaust gas emitted by marine diesel engines. The testing results have now verified that the system's effectiveness in curbing emissions of air pollutants complies with international regulations, and the system has been officially approved by the Republic of Panama, the country where the test ship is registered.

Tech File: Vesconite Rudder Bushings

South American river tugboats need robust rudder bushings: some 20 tug boats on the Parana River, running through Brazil, Paraguay and Argentina, have been equipped with Vesconite rudder bushings. In the challenging waters of South American rivers, tugboat owners began ordering Vesconite’s proprietary thermoplastic rudder bushings starting in 2014. Convinced that the material – which is wear resistant, self-lubricating, environmentally-friendly, requires no grease, and easy to machine and fit – was more suitable than the bronze that has traditionally been used in the application…

EMP Renewable Energy Battery Solution for Ships

A range of marine battery solutions received approval for use on-board ships or marine related applications such as offshore platforms and renewable energy projects. Available from Eco Marine Power (EMP), a developer of renewable energy solutions for ships, in cooperation with storage batteries and electrical machinery manufacturer Furukawa Battery Company of Japan, the battery range has been accepted for use on classed vessels by ClassNK (Nippon Kaiji Kyokai) in addition to having been evaluated by EMP.

NYK Gets Japan's First LNG-Fuelled Tug

NYK Line has taken delivery of Japan’s first liquefied natural gas (LNG)-fueled tugboat from Keihin Dock. "The new tug, named Sakigake, was delivered by Keihin Dock Co. Ltd and is expected confirm the viability of LNG as a marine fuel and to help cultivate a new business field in the area of LNG as an environment-friendly marine fuel,” says NYK. Sakigake has been chartered to Wing Maritime Service Corporation from NYK, and will be operated mainly at the ports of Yokohama and Kawasaki.

Aquarius MAS + Solar Ready for Commercial Use

As a result of the recent successful completion of sea trials on-board the high speed car and passenger ferry, Blue Star Delos, Eco Marine Power (EMP) has now cleared the Aquarius MAS + Solar and Aquarius Marine Solar Power solutions for commercial release. During two days of testing and evaluation on the 17th and 19th May, 2015, the performance of the Aquarius MAS + Solar trial system on-board Delos was assessed by both EMP and Blue Star Ferries technical personnel as part of the Blue Star Delos Renewable Energy Innovation Project.

New Large Engine SCR Systems Debuts at Workboat

Tenneco (NYSE: TEN) has announced that it has introduced a complete urea dosing control, fluid handling and catalyst solution for selective catalytic reduction (SCR) aftertreatment, enabling large engines to meet EPA Tier IV and IMO Tier III regulations. The company will showcase the complete system at the 2014 WorkBoat Show in New Orleans, Dec. 3-5, 2014 (Booth #2152). The system is designed specifically for high-horsepower engines in the marine, stationary and locomotive markets, providing precise and reliable delivery of liquid urea.

MHI, Mitsubishi Kakoki Develop Hybrid SOx Scrubber

Mitsubishi Heavy Industries, Ltd. (MHI) and Mitsubishi Kakoki Kaisha, Ltd. (MKK) have jointly developed a Hybrid SOx Scrubber System that efficiently removes sulfur oxides (SOx) from exhaust gas emitted by marine diesel engines. The Hybrid SOx Scrubber System is the first in Japan to comply with the more stringent SOx emission regulations that will take effect in designated emission control areas (ECA) in 2015. The system is capable of scrubbing exhaust gas from the combustion of fuels emitted from bunker heavy fuel oil to the level combusting more costly low-sulfur fuel oil.

BWTS Fitting on Japanese VLCC a First

Mitsui O.S.K. Lines, Ltd. (MOL) plan to install a ballast water treatment system on an in-service very large crude oil carrier (VLCC). This will be the first such onboard system installed by any Japanese shipowner on an existing VLCC. The company chose the JFE Ballast Ace system developed by JFE Engineering Corporation. The installation will take place while the vessel is docked from March through April. Ballast water discharged while loading/discharging cargo carries marine organisms around the world and can have a negative impact on marine ecosystems and biodiversity.
