Marine Business

Wärtsilä is a market leader in medium-speed main engines. The largest competitors are the other main suppliers of medium-speed diesel engines, Caterpillar (MAK) and MAN Diesel.
Auxiliary engines
The market for auxiliary engines is fragmented and competition on price is intensive. In this segment Wärtsilä’s competitors are MAN Diesel and its licensed manufacturers, HiMSEN engines produced by Hyundai Heavy Industries and high-speed engines.

Energy Business

The main competitors in larger gas-fired projects are gas turbine manufacturers, such as GE and Siemens. When competing against gas turbines, Wärtsilä’s combination of high efficiency, fuel flexibility, and operational flexibility enables better value propositions to many customer projects. In smaller gas power plant projects, and in the heavy fuel oil power plant market, the competitors are mainly other internal combustion engine suppliers, such as MAN Diesel & Turbo, GE Jenbacher, Caterpillar (MAK), and Rolls-Royce. Wärtsilä’s advanced gas and dual-fuel engine technology, optimised modular power plants, superior project management capabilities, and lifecycle services offering have led to Wärtsilä’s market leading position in the gas and liquid fuel combustion engine power plant markets.

Wärtsilä is facing new types of competition while broadening its portfolio of solutions. In the utility scale solar PV business, independent, regional, and local EPC companies are the main competitors. The competition in LNG infrastructure projects comes mainly from contracting companies. When looking at energy system integration, software and battery storage systems, the competition comes from companies such as NEC and Tesla, among others.
