Resulting from a cooperation of the French STX Europe and Stirling Design International (SDI), a radical new concept for a cruise ship called EOSEAS was developed. Although the design is futuristic, its origins date back to a two year French R&D initiative called ECORIZON®, started in 2007 it looked at the five areas of energy management, air emission management, water management, waste management and sustainable design.

EOSEAS is a cruise ship of 105,000 dwt: the pentamaran hull has an LOA 1,000 ft (305 m), beam of 197 ft (60 m) and features five masts able to carry a sails area of 132,500 ft2 (12,440 m2).

Electric power for the hybrid propulsion system and hotel load is provided by gensets and solar panels. Energy in the form of biogas is recovered from the waste treatment system and supplements the LNG fuel.

Four dual fuel LNG diesel electric gensets each of 8 MW, supplemented by 88,800 ft2 (8,300 m2) of photovoltaic panels on side and upper deck panels produce up to 1,08 MW with and average of 270 kWe. There are four screws, two pump propellers with shaft lines on the outriggers and two pump propellers on the main hull.

The ship has a double skin construction allowing natural ventilation through much of the accommodation areas. The is a water recycling plant on board and there is a rain water recovery provision from the upper decks.

The design claims to have met its objective of reducing green house gas (GHG) emissions by 50 per cent. In detail, the reductions are: power consumption 50 per cent, SO2 100 per cent, NOx 90 per cent, particulates 100 per cent. The reduction in CO2 was aimed at 50 per cent but is expected to be 52 per cent being broken down into: propulsion/hydrodynamics 18 per cent, power generation and energy recovery 31 per cent, and hotel load 3 per cent.

When this design was unveiled in 2009, some comments were that it is ten years ahead of its time. As the number of ships using LNG fuel is accelerating and emission regulations become ever more stringent it is doubtful that we will have to wait the full ten years to see this ship built, or something similar using its innovative features.

the subject is very interest, but more details are required.
