Energy-efficient solutions
for cruise ships, ferries and megayachts

We strive to optimize the operational reliability, cost-efficiency, and environmental sustainability of cruise ships.

Most of the world’s harbours are located close to densely populated areas, hence the strong demand during recent years for non-visible smoke. Wärtsilä makes smokeless engines possible.

Smokeless engines

Wärtsilä’s common rail technology is a fuel injection system that facilitates high levels of combustion efficiency, and offers economical power generation whilst reducing exhaust emissions. These benefits are achieved through accurate regulation and timing of the high pressure fuel delivery to the cylinders.

A UNIC (Wärtsilä Unified Controls) engine control system monitors the engine’s operating parameters and uses the resulting data to adjust fuel flow, thereby maximizing performance under all conditions. The system also allows switching between different fuel grades while maintaining maximum efficiency.

Reduction of exhaust emissions

Our existing engines can also be modified with both primary and secondary methods of developed NOX reduction technologies. Primary methods include: dual-fuel engines, an efficiency rudder, highly efficient propellers, oceanguard seals, and CBM (Condition Based Monitoring). Secondary methods include: the Compact Silencer System, Scrubbers, SCR, Senitec products, and Wetpac.

To reduce CO2 and SOX emissions we have increased engine efficiency, developed multi-fuel engines, and produced technologies that advance the efficiency of the entire ship. Our exhaust gas cleaning technology means lower operating costs through access to less costly fuel, avoiding fuel switching, storage, and availability issues, and reducing the operational impact on the environment.

Environmentally sound solutions

The world’s cruise sector is increasingly having to focus on environmental topics. In this technology arena, Wärtsilä continues to set global standards in shipboard waste management by being the world’s leading manufacturer of marine sewage treatment plants and fresh water generation.

Wärtsilä’s ballast water systems are designed to protect the world’s oceans and are suitable for retrofit as well as new build installations. We also offer efficient treatment systems for sludge and bilge water. To reduce emissions to the water, our sealing systems offer environmentally sound alternatives that prevent oil spills.

To ensure maximum efficiency, reliability, and environmental performance over the entire lifecycle of the installation, Wärtsilä’s solutions are customized to meet specific ship design and operational requirements.

Our range of offerings for ferries and Ro-Pax vessels is constantly being developed. Our aim is to be a provider of integrated solutions rather than a seller of components. These solutions are based on well proven concepts, and are tailor-made to fit specific customer requirements with highly efficient systems that fulfil current and anticipated environmental legislation. It was as a result of our Krystallon scrubber, applied to an auxiliary engine during trials on board the P&O Ferries ship ‘Pride of Kent’, that led both the IMO and the EU to bring emissions abatement technology into the legislative framework.

LNG fuel technology

Wärtsilä’s dual-fuel technology and technical solutions to store and handle LNG on board are integral to satisfying demand for a new generation of low emissions vessels powered by natural gas. With extensive experience in this field, our gas systems business has recognised the growing potential for ferries and ro-pax vessels.

Leader in diesel-electric machinery

Diesel-electric machinery offers some clear benefits compared to mechanical propulsion. For instance, the generating sets can be arranged quite freely, which can make it possible to increase cargo capacity. Correctly dimensioned diesel-electric machinery makes it possible to run the diesel engines close to optimum load in all operational modes. This gives better engine performance and lower fuel consumption. The installed power can also be used for many different purposes, while less total power can be needed.

Low Loss Concept

The Low Loss Concept developed by Wärtsilä saves both fuel and installation costs, reduces emissions, and lessens the amount of space required for component installation. This innovation also delivers greater redundancy in the electrical propulsion system, and makes the commissioning work easier.

Noise and vibration abatement

We provide a viable solution for abating noise with advanced flexible mountings, which have many advantages in demanding ferry installations. Together with our Compact Silencer System (CSS), these offer a truly noise-free solution. Wärtsilä propellers are also designed to offer low noise and vibration levels.

Natural choice for environmentally sound shipping

Direct environmental and economic benefits are a feature of Wärtsilä solutions throughout the entire engine power range. Fuel flexibility enables owners and operators to opt for the most suitable fuel, taking into account local environmental restrictions, fuel price variations, and fuel bunkering possibilities. A unique feature of Wärtsilä dual-fuel engines is their ability to run on natural gas, marine diesel oil (MDO), heavy fuel oil (HFO) and liquid biofuels, thereby providing maximum flexibility in fuel choice. 
 

Wärtsilä can provide megayachts with integrated solutions or components that comply with requirements for silence, lack of vibration, compactness, flexibility and efficiency. We use the latest state-of-the-art technologies and seek always to minimize the ecological footprint of the vessel in an economically sound way.

An essential requirement for megayachts is that no smoke, soot, noise, or vibration is transmitted from the engine room machinery to other parts of the vessel. Achieving such levels of performance is by no means easy, but Wärtsilä’s cruise ship, naval and research vessel experience is an invaluable asset in meeting this requirement.
