Stolt Tankers has successfully completed an in-transit hull cleaning trial using Shipshave’s ITCH (In-Transit Cleaning of Hulls) on board the Stolt Acer (pictured) as she sailed from Port Said, Egypt to Algeciras, Spain.

Biofouling on ships’ hulls is a major concern for shipping companies as it not only increases fuel consumption, but can also lead to the transfer of invasive species to non-native waters. In transit hull cleaning gently cleans the hull more regularly than manual cleaning by divers. The reduction in the amount of drag due to biofouling consequently decreases fuel consumption.

Energy and Conservation Manager at Stolt Tankers, Jose Gonzalez Celis said: “The results of the initial trial were very positive. We saw a reduction of fuel consumption during the voyage, and this when combined with some of the other technological developments we are investigating will have a significant impact on our overall fuel consumption.”

Until more environmentally friendly fuels are readily available, Stolt Tankers is exploring several technical solutions to support the transition to a low-carbon maritime industry and plans to expand the Shipshave trial to five more ships. Stolt believes that a greener future will require the right combination of new technical solutions, technology and future fuels.

“Traditionally, ship owners tend to have a reactive approach to vessel maintenance, rather than taking preventive measures.” Adds Lucas Vos, President Stolt Tankers. “As part of our continuous improvement mindset we have turned that idea on its head and found that taking a more proactive stance before biofouling has a chance to settle on a ship’s hull is a far more sensible approach.”

“Reducing the marine growth on the underwater hull of our ships by applying Shipshave’s innovative solution is just one of the ways in which we are improving our energy efficiency with the aim of reducing our carbon intensity by 50% (relative to 2008 levels) by 2030.”

Shipshave’s ITCH performs hull cleaning while the vessel is sailing to prevent the early-stage growth of hull biofouling. DNV has performed a consumption assessment calculation and found that Shipshave’s technology can deliver fuel savings of around 10% when used regularly. The crew of the Stolt Acer also reported that the device was easy to use, clean and maintain.

Supply chain of shipping

Shipshave tries to stay on top of members of the supply chain in shipping’s different approaches when it comes to pursuit of sustainable operations.

As a supplier to the industry of sea going transportation, we are impressed of the efforts implemented.

Shipshave’s outreach is growing

Charlie has broad experience from the marine industry not limited to technical ship-management and from a major marine paint manufacturer. He also has a Specialist Diploma in Data Science – Artificial Intelligence.

Please welcome Charlie!



Shipshave’s organization is complemented

Ivan Rafoss joined Shipshave as Operations Manager on August 1st. It will be challenging to keep the office space that tidy in the time to come.

Please welcome Ivan!



A high value pilot customer has completed the 1st phase of verification of ITCH’s efficiency. Grooming only the starboard side, at the end of the vessel’s docking schedule, a visual and comparative approach was set.

ITCH was operated 3 times prior to dry docking the vessel late December 2021. Comparing port side to starboard clearly shows the removal of the green and white microfouling.

The 2nd phase of the verification will take place once microfouling has established on the fresh coat of paint. Thereafter ITCH will be used on both sides where the fuel economy will be compared to 1-2 sister vessels in identical trade.


Fuel consumption assessment by DNV

DNV’s objective was to assess if the use of ITCH of the wetted surface of the vertical sides has affected the speed-power of the Bulk Carrier. The evaluation is based on noon report data. AIS data for the vessel is used to extract hindcast data with information about wind, waves and current.

The reduction in fuel oil consumption of -10% due to partial hull cleaning has been derived thereof.

Shipshave is very pleased to be presenting here within the identified savings obtained by the use of our In-Transit Cleaning of Hulls (ITCH). We belive that the ITCH is a means to improve the vessels CII-rating and should be considered when compiling the enhanced SEEMP.

The Owner of the vessel in question has elected to remain unnamed, hence the masking of the vessel ID in the image.



Shipshave’s organization is growing

Mohammed Nizar is a Naval Architect who has extensive education in the marine field with a Master’s Degree in Marine Technology, specialized in Marine Hydrodynamics from NTNU and an experienced Ship Surveyor from a leading ship classification society.

As Customer Success Manager he will be a link between Sales and R&D with direct communication with the end users.

Please welcome Nizar!

A good read on ITCH v.1 in an industry magazine

Dry bulk is, and will be in the continuation, a segment of paramount importance to Shipshave. We are happy that DryCargoMag.com has shown a keen interest in ITCH v.1.

Proper, The Missing Link in Under-Water Hull Cleaning

Shipshave has secured funding with Innovation Norway to develop Proper. Proper is a new remotely operated technology to clean underwater ship surfaces such as hulls, propellers, rudders, thrusters and niches. Proper will be a small and robust and can be handcarried and operated by the vessel’s crew.

Propeller surfaces are keys to maintain fuel efficiency and the speed of the vessel. Since many engines will be derated with the new IMO efficiency regulations, ensuring your propeller is clean will allow you to stay competitive.

We aim to introduce Proper to the market during the 2nd half of 2022. Our warp speed R&D guys have already been able to start testing a functional prototype on a ship 4 months after the grant.

The image below shows a surface cleaned of barnacles (left bottom in the picture) vs. uncleaned (right and middle). The final tool will of course clear all fouling. The first prototype is doing well and we are working hard to make your life easy.
