Cruise ships

A cruise ship is an ideal and self-sufficient floating city in constant communication with land. It is designed, built and managed to safeguard the health and life of those temporarily living there for work or fun, thousands of people from different countries and cultures, who live together and adhere to its rules of governance.
Monitoring of regulatory developments is a fundamental element, at a strategic and technological level, in the early identification of possible trends in the market and being able to anticipate the new emerging needs by proposing solutions that are innovative, competitive and comply with the technical, economic and environmental feasibility standards at product and process level.
We have an active and proactive role in the development of international safety regulations and we are an accredited representative with the International Maritime Organization (IMO), the specialized United Nations Agency protecting the safety of human life at sea and the environment.

THE NUMBERS OF COMPLEXITY - What you need on average to build a cruise ship


mq of public space: the size of 3 football fields


design hours


kms of cable: more than 7 times the distance from Rome to Venice


hours of shipyard work

Our ships are a technological benchmark at the global level. They feature the most advanced technologies with technical solutions that provide energy savings, emission reduction, high performance and high quality, guaranteeing very high standards of comfort on board.
For this reason, we have embraced the objectives of the International Maritime Organization, summarized in the slogan “Safe, secure and efficient shipping on clean oceans”.

The reduction of environmental impact has become one of the most important drivers for design and innovation in the field of cruise ships.
We have developed, validated and applied more than 100 initiatives on our ships aimed at:

  • improving hydrodynamic and propulsive efficiency;
  • exploiting waste heat (fumes and cooling water) with recovery and cogeneration systems;
  • systematically reducing the energy needs of users on board.

Fan coil installation in cabins 290 t/year
Fan coil installation in public areas 160 t/year
Variable speed adjustment systems for electric motors 220 t/year
Heat recovery system optimization 270 t/year
Recalibration of drinking water generation system 48 t/year
Increase of electric motor energy class 75 t/year
LED and high efficiency lighting and automatic lighting control 130 t/year

*Data per ship by ca 130,000 GRT (t fuel/year)

Our commitment to reducing emissions of polluting gases is reflected in our adoption of new solutions and technologies, such as:

  • Latest generation diesel engines, combined with the installation of fume purification systems in the exhaust systems.
  • Liquefied Natural Gas (LNG) engines, which allow a significant reduction of emissions compared to traditional engines. This reduction is around 25% in terms of CO2 emissions and over 75% in terms of emissions of other particulates.
    We have already built a special ferry for Canada and in 2018 we achieved some important milestones for LNG cruise ships.
  • Electric or hybrid vessels. The energy supplied by the batteries is used exclusively in particular situations (for example in port) or supplemented by the on-board diesel engines at times of maximum power demand (e.g. maximum speed navigation). Our subsidiary VARD has contracts and offers for various small/medium-sized vessels equipped with electric batteries to cover all or part of the energy requirements.


The future lies in the application of fuel cells, electrochemical conversion devices that generate electricity and heat by combining a fuel and a comburent. Studies and research are being carried out on their application for energy generation on cruise ships.

To protect the areas subject to cruise navigation only bacteriologically and chemically pure water can be discharged into the sea. Any other residue must be stored on board and unloaded in port for further treatment.

In particular, our focus on solid waste treatment is realized using collection, dehumidification, kitchen waste treatment; sorting and recycling of hotel waste; compaction and/or incineration (where permitted) of solid waste; pelletizing, storage of waste for subsequent unloading in port.

Liquid waste initiatives instead concern physical and biological treatment (in line with the best land standards) of all on-board wastewater (sewage, grey water, kitchen and laundry effluents); storage of purified water; thickening and drying of residual sludge for subsequent unloading in port.

To avoid contamination with species from different ecosystems, we sterilize ballast water before discharging it, using latest generation ballast water treatment systems, based on the pre-filtering of plankton and subsequent sterilization with ultraviolet rays.

Naval vessels

The naval sector is also pursuing a procedure to design eco-sustainable vessels in order to adopt solutions aimed at reducing environmental impact both during construction and during the vessel’s operational life.
We have collaborated with the Italian Navy for many years on environmental impact issues right from the preliminary project. The new vessels, some of which are already in service, feature design choices aimed at containing environmental impact in terms of emissions to air, fuel consumption, wastewater treatment, use of special treatments to preserve the hull and the possibility, for certain special vessels to be delivered shortly, to contain an area of sea that is polluted, with the possibility of collecting and storing the pollutants on board.

In particular, we are focusing on solutions aimed at:

Reduction of carbon dioxide (CO2) and nitrogen oxide (NOX) emissions

We are introducing energy savings criteria developed mainly in ship architecture by selecting endothermic engines (both propulsion engines and power generation engines) with appropriate technological solutions and by selecting high energy efficiency materials or materials with high efficiency heat transfer.

Treatment and storage of solid and liquid waste

We have adopted technological solutions for converters. These machines enable solid waste to be dried and sterilized. The reduction in volume and weight and subsequent automatic vacuum storage allow on-board retention to be increased. The modern converters adopted enable a volume reduction of 70% and weight reduction of 30%.
Our focus on the treatment of liquid waste consists of physical and chemical treatment units to collect grey water and sewage and separation units - that separate the pollutants caused by accidental spills – to treat bilge water.


All our ships, cruise ships and naval vessels, are delivered with a Green Passport in accordance with the provisions of the Hong Kong International Convention for the safe and environmentally friendly recycling of ships. The Green Passport contains information on potentially hazardous materials used in the construction of the ship, its equipment and its systems and is updated by the shipowner after maintenance and refitting activities which could alter the state of the ship.
Cruise ships are also provided with Clean Design Notation certification, which indicates that the ship was designed to pollute as little as possible throughout its entire life cycle.
