Sheco: Marine Recovery Robot for Ocean Environment Clean-up

Sheco has developed a robot for marine recovery and water purification to clean floating contaminants, allowing marine businesses and organisations to easily manage contaminated water at their sites.

Market of Implementation

  • South Korea


All water pollution accidents have one thing in common: a massive amount of manual work. Marine businesses and organisations are currently manually cleaning their water sites of contaminants such as algae, bulk dust and microplastics. The inefficient manual work involved creates problems of excessive carbon emissions and industrial accidents. Regulations to curb this problem in the market have been inadequate.

In South Korea alone, in the case of oil spill accidents, there are 270 cases annually, with 530,000 litres of oil split. Around the world, the rate of accidents happens 150 times more frequently.

Currently, more than 90% of oil spill accidents are small-scale, and inefficient manual work of using absorbent pads for more than 200 days is repeated every year. However, there are no lightweight and automated products on the market to resolve small-scale accidents. The South Korean Government possesses many oil skimmers to respond to large-scale accidents of national concern, but not for actual small-scale accidents.

At Sheco, we are filling in the gap for small-scale spill accidents.


We at Sheco, as a marine environment technology company, have developed the "Sheco Ark", a unique automated robot model that is able to enter both traditional oil skimming and oil absorption markets at once. We believe it can replace traditional marine recovery equipment for oil spill accidents, which has not seen much innovation in the recent decades.

In addition to product sales, rental, and recovery services, the components of the Sheco Ark are modular. This allows us to sell the built-in technologies such as the oil-water separation filter, marine drones and driving control software as separate products.

Our overall mission and growth strategy is to use the additional technologies from our Sheco Ark series at oil spill sites, and our aim is to remove all floating contaminants in the ocean and for marine-based businesses.

Type of Carbon Reduced/Sequestered

CO2 (Carbon Dioxide)

Amount of Carbon Dioxide Equivalent Avoided/Sequestered


Means of Measurement

Obtain the coefficient of carbon emission from the incineration of oil absorbents and waste (carbon emission calculation method of the IPCC).

After that, measure the amount of absorbed oil per absorbent pad based on data (the amount of oil spills and absorbent pads used per year, statistics from the KCG). And, calculating by its coefficient, get 3.809T of carbon emissions from incinerating 1T of used absorbent pads, which is about 14,582T per year. Thus, at least 5,800T(40% of total) can be reduced.
