Klaveness Combination Carriers (KCC) has signed a Letter of Intent with technology company Shipshave to implement its semi-autonomous hull cleaning solution across its fleet.

Shipshave ITCH (In-Transit Cleaning of Hulls) performs hull cleaning while the vessel is sailing to prevent the early-stage growth of hull fouling. Shipshave reports that its technology has proven fuel savings of around 10 per cent when in regular use. The operational cost of ITCH is less than 1 per cent of current technologies, according to the company.

A successful pilot of the solution onboard KCC’s vessel Ballard throughout 2021 improved fuel efficiency and provided the shipping company with sufficient confidence to expand the scope of the pilot and aim for fleet-wide rollout.

Biofouling on ships’ hulls is a major concern for shipping companies as it not only heightens fuel consumption by increasing resistance between the ship and the water, but also causes the transfer of species from their native to non-native environments, disrupting the ecological balance. Keeping the hull of a ship clean and free from barnacle growth prevents the transfer of these species and ensures smooth contact between the ship and the water it is sailing through.

Shipshave’s lightweight plug and play ITCH system is a semi-autonomous electric propulsion robot that cleans the hull underwater, while the ship is in operation. The system can be installed and used by crew onboard. Soft brushes move up and down the hull in a defined pattern to remove barnacles.

Shipshave has delivered approximately 10 ITCH robots to date.

“Reducing the marine growth on the underwater hull of our vessels by applying Shipshave’s innovative solution among others, is an important part of KCC’s efforts to improve energy efficiency for substantially reducing CO2 emissions and improving the sustainability of our business,” said CEO of KCC, Engebret Dahm.

“Seeing KCC’s seafarers taking ownership of improving their fuel efficiency is rewarding,” said Eirik Eide from Shipshave.

“We see an accelerating uptake from KCC and other shipowners driven by a desire to go green and the upcoming Carbon Intensity Indicator,” added CEO Rune Freyer of Shipshave.
