QUADRIGA AQUA
SUSTAINABLE MOBILE AQUACULTURE
A CRADLE-TO-CRADLE PLATFORM FOR NATURAL SEAFOOD FARMING
AND THE OPPORTUNITY TO SUPPLY SUSTAINABLE PROTEIN TO THE BENEFIT OF MANKIND
NATURAL SEAFOOD FARMING
High-quality seafood will be farmed on board of a sailing vessel in mid ocean. The animals will be raised in their natural environment in ship-based breeding tanks.

CO2-NEUTRAL SAILING SHIP
The farming technology will be hosted by sailing vessel relying on wind and renewable energy sources for propulsion and operation of aquaculture on board.

CIRCULAR ECONOMY CONCEPT
The integration of aquaculture and mobility will allow for true sustainability and lead to a new dimension of seafood farming.

CIRCULAR ECONOMY CONCEPT
Closing the loop: Our Cradle-to-Cradle platform for seafood farming aims to achieve true sustainability by relying on natural energy sources and returning biomass to the oceans.
INNOVATIVE DESIGN OF COMPONENTS
- Using existing parts and adapt for different context
- Fostering interdisciplinary collaboration in the areas of breeding tanks, piping systems and water treatment
WIND PROPULSION AND RENEWABLE ENERGY
- GHG neutral propulsion
- Solar cells on deck
- Wind and water powered generators
- Clever storage of surplus energy
SUSTAINABLE AND RESILIENT FARMING
- Seafood farming in natural habitat
- Focusing on animal welfare
- Seafood farming in natural habitat
- Focusing on animal welfare
NATURAL CAPITAL ALONG THE VALUE CHAIN
- Natural sea water for floating the breeding tanks
- Avoiding diseases and pests by constant monitoring (no medicine or toxic substances)
- Returning excreta back to the oceans

VISION
SOLVING THE CORE CHALLENGES OF OUR AGE
- Our success is directly related to the quality of fish and per kilo price on the spot markets.
- We are not affected by charter cates.
- There is no connection to bulker or container markets.
VALUES
PLACE TO BE FOR WORLD CHANGERS
- Contributing to a carbon-neutral future
- First serious sailing ship for commercial use
- New dimension of seafood farming
- Visionary entrepreneurs and experienced professionals
The project Quadriga Aqua is shaped for passionate people who opt to contribute positively to the moral ecology of the future.
The commercially viable and profitable project combines environment-friendly sail propulsion with innovative technology for seafood farming.
Quadriga Aqua is designed to be the world’s biggest commercial sailing vessel fitted to reduce global ship-sourced GHG emissions.
Quadriga Aqua will host the first sustainable seafood farm and contribute to meet global protein demand.
Quadriga Aqua is powered by Sailing Cargo, a junior independent company accompanied by experienced partners.

KNOTS
SUSTAINABLE PRODUCTION
1. PREMIUM QUALITY SEAFOOD FARMING
The focus is on the well-being of the animals. Fish will be fed balanced diets, foregoing any medication, protected from predators and other stress factors.
2. no risk
from toxic floating algae, warm waters or pollution of the marine ecosystems. A sea-going aquaculture is able to avoid these dangers by simply changing the course.
3. NEAR-ZERO FOSSIL ENERGY CONSUMPTION
We rely on wind power as clean energy source. The 2nd generation of ships will be supplied by renewable energy sources only.
4. NO CONTAMINATION
from organic waste, disinfectants or antibiotics. Fish excreta will be widely dispersed through the ship movement.
technology behind

- 15 independend production lines for fish breeding
- Minimal risk of infection, contamination and total loss
- Various sizes of breedingtanks for different stages of growth
- Tubes for continuous water exchange
- Turbines for power generation and power supply of process technology
- Perfectly tempered water at natural pressure circulates through the ship
- Several big torpedo tubes supply the breeding tanks with fresh seawater
- Flow velocity in the tanks is identical with the flow of the ship
PROCESS OF FISH PRODUCTION ON BOARD
The integrated value generation ranges from farming of post-smolt larvae in ship-based breeding tanks to the distribution of fresh fish. We plan to start breeding with “Salmo Salar”, driven by the fact that Atlantic salmon leads the consumer statistics for fish.
NURSERY
Post-smolt salmon (fingerlings) is expected to be supplied by EU hatcheries. The intake of fingerlings together with the delivery of the market fish to a port of destination, on board the ship or on quay is planned at three-monthly intervals.
MONITORING
Until marketability, which will be achieved within 12 month after stocking, the fish will be constantly monitored and subjected to veterinary examination at regular intervals. The fish will be held without any medication. Better materials improve self-cleaning and discharge of dissolved and particulate by-products.
GROW-OUT
The fish will be kept in flow-optimized breeding tanks with tube profiles. The tanks will continuously be supplied with fresh sea-water, allowing for keeping the fish in a natural environment. The water will be brought into the ship through opening flaps in the ship’s hull, controlled by the natural pressure and constant movement of the ocean.
SALES
The highly integrated value generation is expected to provide a maximum impendency from existing markets and food producing companies. At the same time, this configuration gives the flexibility of calling at ports with the highest market prices at any given time.
