Zero emissions of CO2, NOx, SOx, particular matters
We use no fossil fuels and thus avoid the above, along with no discharge of toxic waste water, as we see today, when ship owners use scrubber technology to comply with regulations.
No ballast water and
About 1/3 of todays tonnage shipped is ballast water, used to balance the ships when not fully loaded. A large iron ore carrier, transports 100,000 tons of ballast water from China to Brazil which needs to be poisoned or electrified to reduce the spread of invasive speices.
Liberty does not use ballast water,delivering substantial fuel savings, increasing payload space with less piping, no pumps, filters or chemicals aboard for ballast water treatment.
These ships are relatively straightforward systems, as we have less heavy technologies onboard. We have no massive diesel engines or heavy fuel tanks, massive propeller shafts, less lubricants and almost no piping.
Ability to serve shallow
draft ports and water ways
Reduced weight and the multihull design allow us to service shallow draft ports, closer to the origin of the cargo as well as closer to the end user. Some shallow water countries like India and Bangladesh can reduce their inland transport significantly.
We will move large volumes of cargo from road and rail onto sea transport contributing further reductions in CO2 and other air emissions. We can also sail different routes, take shortcuts and avoid some of the narrow straights that are heavily crowded with traditional vessels.
Low operational costs
We have no fuel expenses and less terminal expences and no need for on shore power supply, nor chemical, sludge or wastewater disposal requirements.
Low maintenance cost
All surface structures are made of composites, which need less maintenance than traditional steel surfaces when exposed to sun and saltwater. We have 4 electric drive engines, which also require less maintenance than similar sized combustion engines.
Improved product life cycle
Today we recycle about 90% of the materials used for ship building, but the environmental effect of recycling steel ships, transporting the steel from the scrapyard to the steel plant, melting and producing new product and another transport is very costly energy wise compared to a composite hull.
Additionally we expect these ships to be in service for a minimum of 30 years, as they can easily be upgraded with more effective photovoltaic panels and rigging.
and sea keeping
We have a good length / breath ratio, with two 360 dg rotating azimuth propellers in each side hull, allowing for easy maneuvering. The low volume in the stern of the hulls, gives a wave piercing performance resulting in plain sailing, even in extreme wave conditions.
Low noise and
We expect to run 60-70% of the time from pure wind propulsion, 20% with assisted engine propulsion and 10-15% on pure engine power, delivered by two electric drives with almost no noise or vibration.
Safe and easy mooring
Shallow waters ports: The wing and the azimuth propellers allow precise maneuvering even in heavy weather, and all moorings are automatically adjusted
The ambition of Blue Technology is to develop solutions which eliminate many of today’s challenges and help the maritime industry on to a truly sustainable path.
