Wärtsilä and Mitsubishi to collaborate

Dec 15 2017

Wärtsilä and Mitsubishi Heavy Industries Marine Machinery & Equipment (MHI-MME) have signed a Memorandum of Understanding (MOU) to commercially market new ship energy solution.

Both companies will combine technologies to produce greater power generation capacity and higher propeller propulsion.


By integrating MHI-MME's waste heat recovery system and energy saving power generation system (WHRS) with Wärtsilä's operational control technology for shaft generator systems, the new solution results in more energy efficient ship navigation and an improved Energy Efficiency Design Index (EEDI), the companies claimed.


A notable innovation is the combining of a power take off/take in (PTO/PTI) shaft generator system with the WHRS to improve the stability of the WHRS. Depending on the load of the main engine and the ship's network, the WHRS sometimes produces electrical energy in excess of that needed by the network.


"When two technology leaders combine their fields of expertise, as is the case here, a solution can be created that raises efficiency to a new level. This will produce obvious benefits for shipowners and operators, and we are proud to be co-operating with Mitsubishi in this exciting development," said Peter Rogers, director, power conversion, Wärtsilä Marine Solutions.


"We are moving forward various energy-saving technologies and can expand our portfolio with this new solution, which we are quite convinced will satisfy present market demands for increasing environmental awareness. We wish to thank Wärtsilä for its high-quality collaboration that has made it possible," said Tomoo Kuzu, MHI-MME executive vice president.


The new energy solution is expected to be relevant to various types of vessels, including tankers.


As well as this initiative, Wärtsilä launched Wärtsilä Linesafe at Marintec, adding it to its seals & bearings product portfolio.


Its simplified design enables short lead times, as well as fast spare part delivery and service response. In addition, the updated bearing design offers enhanced flexibility within the standard design, which can allow customers to select different product configurations based on their needs, the company explained.


"The new Wärtsilä Linesafe is revolutionary. It's a major step forward in bearing design," said Laura Lois, product manager, Wärtsilä Seals & Bearings. "The Wärtsilä Linesafe is designed to address the needs of marine and offshore owners and operators. The bearing design addresses market requirements, such as increased radial load capacity, allowable shaft slope, as well as a reduced amount of oil necessary for operation.


“The modular design enables the Wärtsilä Linesafe bearing to be tailored for use in various operating environments, and in customer-specific applications," she added.


Further operational improvements to the standard design include readiness to connect a pump when forced lubrication is required, water cooling availability, interchangeable upper and lower bearing shells, and self-aligning design. In addition, the system can be equipped with a 'safe return to port' functionality when in flooded conditions.


"The new Wärtsilä Linesafe for propeller shafts is suited for all vessel types. Wärtsilä Linesafe will replace all prior variations of Wärtsilä's intermediate shaft bearing solutions," said Matthew Bignell, sales development manager, Seals & Bearings. "In addition to this innovative product development, Wärtsilä provides customers with worldwide field service support and technical expertise with its global network."
