Wartsila approves cylinder oil that mitigates the effects of cold corrosion

Mobilgard 5100 has received an interim No Objection Letter (NOL) from Wärtsilä after demonstrating its ability to mitigate the effects of cold corrosion in new design and modified two-stroke marine engines operating on heavy fuel oil. The NOL covers use of the cylinder oil in the company's RTA, RT-Flex and W-X engines. This follows the successful completion of a 2,000 hour field test in a Wärtsilä 7RTFlex96C engine on board a container ship, including extensive engine inspections and cylinder oil analysis. Mobilgard 5100 helped eliminate cold corrosion in the engine while operating at Wärtsilä's minimum recommended feed rate of 0.8g/kWh. ExxonMobil created Mobilgard 5100, a 100 BN cylinder oil, in close collaboration with leading marine engine builders. It has been formulated to address the problem of cold corrosion which occurs when engine cylinder temperatures fall below the dew point of the combustion gases, . creating the potential to cause significant liner wear. "The interim No Objection Letter from Wärtsilä is a further indication of how Mobilgard 5100 can effectively protect against costly cold corrosion issues," said Iain White, field marketing manager, ExxonMobil Marine Fuels & Lubricants. "Mobilgard 5100's formulation delivers outstanding results at lower feed rates, helping optimise performance in ...

Wartsila signs engine manufacture agreement with JAD

A licence agreement covering the manufacture and sales of Wärtsilä 2-stroke engines has been signed between Wärtsilä Switzerland Ltd and China based Jangsu Antai Power Machinery (JAD). JAD is the former large horse-power division of Wuxi Diesel Engine Plant. Under the terms of this agreement, JAD will be able to manufacture and sell the entire portfolio of Wärtsilä 2-stroke engines. Initially, JAD will focus on small and mid-sized engines up to and including the Wärtsilä X-72 bore engines. It is expected that the manufacturing capacity of JAD will make a significant contribution to the delivery of Wärtsilä low-speed marine engines to the large and still growing Chinese shipbuilding industry. "We are delighted to establish this co-operation with one of China's major engine producers. Jangsu Antai Power has a well-deserved reputation for quality, and together we can serve our customers in China with faster delivery of Wärtsilä engines featuring the very latest technology," says Martin Wernli, Vice President, 2-stroke, Wärtsilä Ship Power and Managing Director of Wärtsilä in Switzerland. JAD was awarded ISO 9001 quality system certification as early as 1996, and is approved by CCS, BV, GL and other classification societies. The agreement was signed at a ceremony in Jingjiang ...

Wärtsilä Yuchai Engine a joint venture between Wärtsilä and Yuchai Marine Power has inaugurated its new factory in Doumen District, Zhuhai City, Guangdong Province, China. The new factory covers a total area of 266,700 square meters and will be used for the assembly and testing of Wärtsilä 20, Wärtsilä 26 and Wärtsilä 32 medium speed engines. The assembly lines and test beds are in partial operation already, and the plant is expected to be in full production before the end of 2016. Wärtsilä and Yuchai Marine Power Co. Ltd. (YCMP), a subsidiary of Guangxi Yuchai Group, established the 50/50 joint venture in May 2013. The joint venture, for which the value of Wärtsilä's investment was approximately EUR 17 million, will strengthen Wärtsilä's competitiveness in the Asian markets and increase its focus on the offshore and special segments in China, the world's largest shipbuilding country. "As China is the world's major supplier of newbuild ships, the Chinese market plays a central role in Wärtsilä's global growth strategy. By inaugurating another Wärtsilä joint venture in China, we not only demonstrate our strong commitment to this important market, but also take another significant step towards enhancing our presence in the region. Strengthening our ...

Wartsila signs agreement to support Harvey Gulf’s LNG PSVs

Wärtsilä has signed a long-term Technical Management Agreement with Harvey Gulf International Marine LLC (Harvey Gulf). This five-year agreement was signed in August 2014 and it covers Condition Based Maintenance and Dynamic Maintenance Planning for eight new offshore supply and multi-purpose support vessels - six liquefied natural gas (LNG) fuelled platform supply vessels and two offshore construction vessels powered by diesel fuel. The signed agreement ensures ideal running conditions and optimized maintenance for Harvey Gulf's new vessels. It ensures that their engines - 18 Wärtsilä 34 dual-fuel engines and eight Wärtsilä 32 engines - always run at the optimal level, with optimized fuel economy and maintenance costs. Technical management is based on continuous condition monitoring data and periodical inspections. The agreement also includes Online Remote Operational Support, which enables Wärtsilä's technical experts to support vessels in real time, without the need for engineers to travel to the vessels. "Harvey Gulf's decision to become the leader in Clean Gulf of Mexico offshore operations has been enthusiastically accepted by oil company executives. And we are extending our partnership with Wärtsilä, through this Technical Management Agreement, to assure our new fleet of vessels are maintained to the highest standards of safety, reliability and ...

Wartsila launches technical solution for LNG fuel handling

The latest Wärtsilä developments in the field of LNG as a marine fuel, involve an upgraded version of the Wärtsilä LNGPac, a fully integrated fuel gas handling system, and improvements to the coveted Wärtsilä Gas Valve Unit (GVU). Wärtsilä introduced the LNGPac in 2010. It comprises a system for LNG fuel handling, which when introduced included the bunkering station, the LNG tank and Tank Connection Space with the required process equipment, the heating media skid, and the control and monitoring system. It is a system that has proven to be a valuable enabler of LNG fuel for marine applications with more than 20 LNGPac systems in operation or under construction. By upgrading the system into a more compact and technically advanced version, safety and reliability will be enhanced, while the capital and operating expenditures (CAPEX & OPEX) will be reduced. The new system has fewer moving parts, and therefore less maintenance is required. Furthermore, the compact design and advanced integration of components makes installation at the shipyard faster and easier. The heating media skid, used to evaporate LNG for pressurising the storage tank and to provide the engine with the correct gas temperature, has now been removed as have the ...
