Whatever the vessel’s operating profile, Wärtsilä offers customized solutions that meet your specific needs as a ship owner or operator of a cargo vessel. Wärtsilä’s innovative approach and broad product portfolio enable fit-for-purpose cargo vessels that have the flexibility needed to achieve significant environmental and economic benefits. Thus, ensuring your vessel is compliant and meets both local or global operating regulations and legislation as well as maximising profitability.
Wärtsilä’s ability to combine products into a single solution package that combines ship design, engines, gearboxes, electrical & automation systems, propulsion, seals & bearings and environmental solutions, provides guaranteed performance of the complete package install. A single solution package also has the added benefit of uniformed documentation, a single point of contact, and Wärtsilä’s efficient propulsion plant in which all parts are engineered and designed to work in harmony.
Improving efficiency is a known requirement but how can this be achieved. In this short video we explore how to decrease energy consumption to increase profitability and at the same time reduce emissions.
Pressure on owners and managers in the merchant fleet is increasing and identifying ways to reduce costs is central to relieving some of this pressure. Explore some of the short term solutions available to achieve this in this video.
The technology group Wärtsilä introduces its new Wärtsilä 25 medium-speed 4-stroke engine. Based on Wärtsilä’s highly successful modular technology platform, this latest addition to the company’s engine portfolio is designed to accelerate and support the maritime sector’s efforts in achieving decarbonised operations.
The Wärtsilä 25 engine’s modularity offers shipowners and operators maximised flexibility, while the engine’s efficiency and fuel economy deliver minimised emissions. The engine is already capable of operating on diesel, LNG, or on either gas or liquid carbon-neutral biofuels, and can easily be upgraded to operate with future carbon-free fuels as they become available. The flexibility of having different valve timing options is a key enabler for future fuels and emissions optimisation.
The Wärtsilä 25 is intended to be the first Wärtsilä engine to run on Ammonia as a fuel – technology development is currently underway with a technology concept readiness slated for 2023, followed by planned product release soon thereafter.
“This engine marks the beginning of a new era of future-proof medium speed, small-bore engines, and comes as an important step towards the maritime industry meeting its decarbonisation goals. The Wärtsilä 25 ticks all the boxes. It is a small but powerful engine, and it provides an effortless transition to future fuels, making it a future-proof investment already today. Most importantly, the Wärtsilä 25 brings all of these advantages whilst keeping the total cost of ownership within reason.” says Roger Holm, President Marine Power & Executive Vice President Wärtsilä Corporation.
When operating with natural gas the engine is IMO Tier III compliant, as it also is with diesel when integrated with a Wärtsilä NOx Reducer (NOR) emissions abatement system. Furthermore, it enables economically viable compliance with regulations such as the IMO’s CII and EEXI protocols that enter into force in 2023.
The Wärtsilä 25 is designed for long periods of maintenance-free operation and it supports dry-docking schedules with a time-between-overhauls (TBO) of up to 32,000 hours. As a result, both downtime and operating costs are significantly reduced. Data-driven dynamic maintenance planning and predictive maintenance services can extend the TBO even further.
The Wärtsilä 25 features a robust and highly efficient turbocharging system with a high pressure ratio. It is now available in 6L, 7L, 8L and 9L cylinder configurations, while the dual-fuel (DF) version has a power output ranging from 1.9 to 3.1 MW, and the diesel version from 2.0 to 3.4 MW. The common-rail high pressure fuel injection technology optimises combustion and the fuel-injection settings at all loads. This in turn promotes smoke-free operation.
Other features include a self-learning proportional, integral, derivative (PID) control to reduce calibration needs, and the gathering of critical engine data for predictive maintenance, reporting and analysis purposes via Wärtsilä’s Expert Insight service. The modules can be replaced ‘on the fly’, which eliminates the need for separate software downloads. Optional and easy-to-apply adjustments for arctic or tropical conditions and for reducing emissions to the level of a pure gas engine are also available.
