On Friday, June 5, 2026, PGZ Stocznia Wojenna, part of Polish Armaments Group (PGZ), signed a contract under the Ratownik program for the Polish Navy with Warsaw-based Polish company EcoExhaust for the design, production, and delivery of complete exhaust gas cleaning and cooling systems for the vessel under construction.

The technical requirements in this area are exceptionally strict. The exhaust gas temperature at the engine outlet exceeds 400°C; at the overboard discharge, it must be no more than 60°C across the entire engine load range, even at very high vessel heel angles. At the same time, naval vessels must minimize their thermal signature, or infrared visibility, and suppress noise transmitted through the exhaust system, which generates the vessel’s own underwater acoustic signature.
The scope of delivery includes four exhaust systems with seawater exhaust gas cooling for the main engines, as well as a dry exhaust system for the emergency generator, all in a compact, lightweight design made of corrosion-resistant materials.
“We are building Ratownik on the assumption that wherever Polish engineering expertise exists at the required level, we will turn to a domestic supplier. EcoExhaust has proven that Polish technology companies are ready to carry out specialized tasks in defense projects without compromising on quality,” said Marcin Ryngwelski, MBA, President of the Management Board of PGZ Stocznia Wojenna.

The rescue vessel has been under construction at PGZ Stocznia Wojenna since November 26, 2025, when the first steel cutting took place, while the keel was laid on February 4 this year.
The Project 108 rescue vessel, being built under the Ratownik program, will be a large unit with a displacement of around 6,500 tonnes, a length of approximately 96 m, and a beam of 18.8 m. The vessel is expected to reach a speed of around 18 knots and have a range of approximately 6,000 nautical miles. Its crew will consist of around 100 people, with accommodation also provided for an additional nine personnel. The vessel will replace the aging rescue ships of the Polish Navy and will serve both as a national asset and as part of NATO operations.
On October 8, 2025, during the 23rd International Maritime and Military Fair BALTEXPO in Gdańsk, PGZ Stocznia Wojenna signed an agreement with the German company Schottel for the delivery of azimuth thrusters for Ratownik.
On December 6, 2025, a contract was signed in Canada with OSI Maritime Systems for the delivery of the Integrated Bridge & Navigation System, or IBNS, which will be a variant of the advanced Integrated Navigation & Tactical System, or INTS.
On December 10, 2025, an agreement was signed with the British company James Fisher and Sons PLC, or JFD, for the integration of an advanced saturation diving and submarine rescue system.
On February 20 this year, an agreement was signed with the Norwegian company STADT Naval AS for the delivery of a comprehensive propulsion system.
In turn, on May 26, PGZ Stocznia Wojenna reached an agreement with Szczecin Shipyard “Wulkan” for the construction of Ratownik’s bow hull block.
The vessel is scheduled to be launched in 2027, with delivery to the customer planned for the end of 2029.
