A new underwater robot has been invented to clean ships to cut emissions and protect marine ecosystems, says an article published in World Economic Forum.
The Underwater Cleaner Robot
The build-up of marine plants and animals on ship hulls is an age-old problem. This ‘biofouling’ can increase fuel consumption by up to 40% and boost emissions. It can also transport species to new environments where they cause havoc in the local ecosystem. But now a robot has been invented that cleans ship hulls every time they anchor. Its makers say it will bring huge environmental benefits.
Biological Fouling
A ship making its way across the ocean might look elegant as it cuts serenely through the waves. But a look below the water reveals with countless aquatic species like barnacles covering the craft’s hull.
It’s been estimated that severe underwater biofouling – as this accumulation of drag-inducing marine life is known – can increase a ship’s fuel consumption by up to 40%, boosting already high CO2 emissions. More than 4,000 marine species have been identified as biofouling organisms.
Maritime Transport Emissions
Maritime transport emits around 940 million tonnes of CO2 annually and is responsible for about 2.5% of global greenhouse gas emissions. It’s been estimated that if global shipping were a country, it would be the sixth biggest polluter, generating more emissions than Germany.
