Product design principles


Wärtsilä strives to develop environmentally sound, safe, and reliable products and solutions for its customers. By providing lifecycle maintenance, reconditioning, and retrofitting services for its products, Wärtsilä is able to support its customers' operations throughout the entire life of service of Wärtsilä products. Reconditioning of engines and components increases the reliable service life of the products. Modernising can improve current operational performance of installations and enables customers' operations to meet tightening future regulative requirements.

Meeting regulatory requirements

The majority of the international environmental policies and requirements for Wärtsilä’s products and solutions are set by the International Maritime Organization (IMO), and the International Finance Corporation (IFC), a member of the World Bank (WB) group. On the regional or national level, organisations such as the United Nations Economic Commission for Europe (UNECE), European Commission (EC), US Environmental Protection Agency (EPA), and other emission standards such as in Germany, Japan, and India are considered the most important policy and regulatory directors for Wärtsilä products.

The IMO is responsible for adopting its own standards for the safety and security of shipping and the prevention and control of marine pollution and emissions from vessels. The IMO regulates nitrogen oxides and fuel sulphur content as well as ballast water treatment procedures and limitations. The IFC provides general and industry specific Guidelines of Good International Industry Practices (GIIP) such as the Environmental, Health, and Safety (EHS) Guidelines for Thermal Power Plants, which is today considered the minimum environmental standard in larger global power plant projects. It is adhered to in most of the projects financed by international financial institutions in emerging markets. In the European Union (EU), the Industrial Emissions Directive (IED) and the Medium Combustion Plant Directive (MCPD) set the requirements for large and medium-sized combustion plants to minimise pollution from different industrial sources throughout the EU.

Wärtsilä's engines are designed to meet the requirements of the EC’s Machinery Directive, the SOLAS Convention and other relevant safety directives. Wärtsilä's propulsion systems are designed to comply with the SOLAS and safety requirements of relevant classification bodies. New types of engines must also meet international safety requirements. Type approval is acquired from classification societies before new products are launched. Wärtsilä's ship design follows class society and flag state rules in the design process to secure safe and compliant designs for its clients. Class approval is required for drawings and calculations to be delivered to the client before construction of the vessel starts.

In order to ensure Wärtsilä’s ability to respond to future regulation requirements, the company actively monitors legislative initiatives and changes in environmental legislation. As a result, Wärtsilä has focused its R&D activities on the development of new environmentally sound products and solutions that meet the future demands of the changing operating environment.

Lifecycle approach

Wärtsilä's products have a long operational life. Therefore, identifying the lifecycle impacts of our products is essential for understanding their total environmental impact. Wärtsilä manages the lifecycle of its products through product design, careful selection of suppliers, production methods, optimising transportation, maintenance and repair during the operational lifetime of the products, and by training and advising our customers in using the products and systems in the most efficient way. Wärtsilä offers service agreements and products that help customers to optimise their operations. Furthermore, Wärtsilä actively supports customers in selecting suitable solutions in the early phase of projects.

Wärtsilä's products are delivered with appropriate user guides that include basic information about the products and full instructions for their use. In addition, Wärtsilä provides appropriate specific training to ensure environmentally sound and safe utilisation of Wärtsilä’s products at customers’ daily operations.
