Brush cleaning vs CleanHu

Traditional Hull Brushing HP Water Cleanin

• Diver operated• Thruster Force against hull varies from diver to diver, big problems on Silicone• Remove upto 1 year SPC, average 8 months• Brushes abrade the anti-fouling, cause grooves which promote new fouling. 

• Remote operated• Thruster Force and distance no problems to clean Silicone• Do not harm the SPC, documparties (TI, NIVA, SFT, SafetechSuppliers)• No off hire – can be done alo

Scenario – Potential savings

Scenario is based on 12000 Kw and fuel consumption 50t/24h.

Typical added resistance 1% pr. month to max 36%.

A cleaning every 6th month will reduce the fuel consumption by 10 800 t over a 5 years dry-do

corresponding to approximately 2160 t or 432 000 USD per year.

A cleaning every year will reduce the fuel consumption by 9 000 t over a 5 years dry-docking 

corresponding to approximately 1800 t or 360 000 USD per year.

Environmental Benefits

• Reduced emissions to air.

• E.g. 5% reduction, based on 50t/24h = 7,5t CO

2 pr. 24h

• Minimal contamination of the sea and the se

• ”No” Copper lekage, compare to IMO req. 

• Reduced risk for bio transfer / foreign spec• Waist return can be arranged when neededCONFIRMED by :• Analysis and tests by NIVA (Norwegian Institute for Water Research) • Approvals from SFT (Norwegian Pollution Control Authority)• AMBIO report and approvals from the Environmental Department in Gothenburg
Certificate

There’s a bonus for Norowners, as the Norweggovernment recognises environmental benefits and gives owners and cwho use it, a tax credit.
Environmental Benefits

The operator ”FOCUS”, have 20 ships in their fleet.They do regular hull cleaning, they save 5% on fuel conand save the enviroment by major reduction in the CO2 This is a great saving for the shipowner as well as for th
