R&D  Navalprogetti





New solutions for energy saving
and hull optimisation. Alternative fuel propulsion.

Navalprogetti Srl is the Lead Partner of the ACTIVE project
which, as a research and development project in the field of Maritime Technology, is co-financed by the European Regional Development Fund.

The objective of the ACTIVE project, launched in 2017, is to define a new type of inland waterway vessels characterised by low investment and running costs in order to relaunch the inland navigation.

Navalprogetti has designed and studied an innovative class Va hull (110m, 11.4m and 2.8m) for containers/coils transportation. In order to increase performance in navigation, the AIR-CAVITY system has been realized: in a structural recess obtained on the bottom of the ship, an air cushion is kept stable by means of blowers, thus reducing the wetted surface of the hull. The system significantly reduces the resistance (up to 20%) and consequently the installed power.

The use of liquid natural gas (LNG) or compressed gaseous gas (CNG) as fuel reduces costs and emissions.


Fuel cells and energy recovery systems
applied to ship.

Navalprogetti is the lead partner of RESHIP, a European co-funded Project, included in POR FESR 2014-2020 context.

In order to deal with IMO guidelines, which impose severe limits to ship emissions, Navalprogetti wants to give its contribution to the reduction of carbon footprint, choosing the alternative fuels route. Based on ship market and energy analyses, liquid hydrogen (obtained from renewable energy) was identified as the most suitable option to reach zero global emissions. Navalprogetti is at the same time developing:

  • an energy generation system, in collaboration with the University of Trieste – Power Engineering Department, based on the use of PEM-FC, available to be installed on board;
  • and a hydrogen propelled ship design, a double ended ferry, following safety and security requirements.

All research and design activities had been followed by Lloyd’s Register specialists, in order to obtain the Approval in Principle and the certification for the Project.

> The GASVESSEL Project

The GASVESSEL project provides a novel, efficient and flexible method for transporting Compressed Natural Gas (CNG).

It introduces an innovative solution for manufacturing pressure cylinders that are 70% lighter than state-of-the-art alternatives. These superlight pressure cylinders enable new ship designs with much higher payloads and dramatically lower transportation costs per volume of gas. Where the exploitation of stranded, associated and flared gas is currently economically not viable, GASVESSEL brings a solution. As a cost-efficient and flexible CNG transport system that can unlock energy resources and decrease Europe’s dependence on a single supplier.

The GASVESSEL project focuses on:

  • Development and piloting of the lightweight pressure cylinders;
  • Finalizing the ship design based on the new pressure cylinders and including a gas on/off loading system;
  • Establishing proof-of-concept through a cost-benefit analysis, environmental evaluation and safety classification.

Where and how can the GASVESSEL concept provide added value? Three geo-logistic gas exploitation scenarios will be analysed:

  • East Mediterranean gas fields – enable supply of remote areas such as the Greek and Italian islands and Cyprus;
  • Black Sea region – flexible solution for early start-up of gas exploitation, before the planned pipeline will be finished;
  • Barents Sea offshore oil field – exploit gas associated to oil winning.
