Synergy Marine Group revealed it has been growing fresh produce onboard one of its tankers since September using three refrigerator-sized autonomous growing units from tech firm Agwa.
Suezmax tanker Effie Maersk has three of the units onboard, growing up to four bowls of salad per week as well as herbs for seasoning, the companies said. The technology aims to provide a constant source of fresh vegetables to improve seafarer diets, providing vitamins and dietary fiber without costly fresh produce deliveries.
The cabinets have three cameras and sensors for water, pH, temperature, and humidity to monitor the development of plants growing on the shelves inside, data which is used to optimize growing conditions for the plant by adjusting levels of light, water, fertilizer, and temperature. The ideal conditions promote quick growth, better yields, and reduced waste.
The system is AI-powered and fully autonomous so as not to burden crews, according to Agwa, requiring only occasional progress checks. Each unit measures 1.2 meters tall, 60 cm wide, and 60 cm deep, and contains 60 planting pockets, according to Agwa's website. Controlled by an app, the system advises the crew of the optimal time to harvest.
