Professional tank cleaning, gas-freeing and cargo residue management for product tankers.
Tank cleaning and gas-freeing services from VOTPI ensure that cargo tanks are thoroughly cleaned and safe for the next cargo loading operation. We use approved tank cleaning machines, environmentally compliant chemicals and inert gas stripping systems to remove hydrocarbon residues, sludge and water.
