M.E.S., Marine Engineering Services S.r.l., is project leader of TUGA (Escort Tug Gas Propelled), a research and development project in the  field of maritime technologies. The project is co-funded by the European Regional Development Fund and in the framework of Regional Operational Program (2014-2020), Investments to support Growth and Employment Objective 2014-2020, Axis 1 – “Strengthening research, technological development and innovation”, Action 1.3 – “Support of collaborative R&D activities for the development of new sustainable technologies, products and services “.

The project TUGA is started on 1st October 2018 and it focuses on the study and design of a escort tug unit to support ship’s operations and improve navigation and maneuvering in restricted waters.

TUGA will plan a small-dimension unit integrated with a liquefied gas propulsion system designed to increase the competitiveness when compared to the traditional propulsion systems currently in use. Moreover, the research project will study the correct arrangement of the fuel containment system and optimizing the geometries while taking care of the safety requirements.

A calculation code for the determination of the dynamic equilibrium in escort operations will be developed together with software for the simulation of the rigid motion of tugs exposed to hydrodynamic resistance and propulsive forces. The results will be validated in a relevant environment with experimental tests in the ship model basin.
