Ultra-high pressure water blasting is an ideal process for removing paint and corrosion in the marine industry. We have performed a wide range of projects on various vessels both in dry dock and alongside. Our fully encapsulated deck blasters contain blasting debris which is sucked away leaving a clean surface. A popular process is ‘wash and spot’. This delivers a hard wash of the surface followed by spot blasting of corroded areas. Due to the low flow rate of some of our equipment we can operate while the vessel is at sea or alongside without the need for dry-docking.


NSB Protective Coatings is one of this country’s largest corrosion control companies. Managing Director, Craig Ross, was faced with a demanding surface preparation task – removing coatings from the Port of Napier’s tug, Ahuriri.

An added complication was that the project was to be completed with the vessel afloat and general port operations were not to be disrupted.

Aquamax got involved and put together a project methodology to enable a comprehensive strip of the deck and pilot house to a SA 2.0 (medium) standard without use of garnet. The wet process ssisted the containment of dust and blasting debris and the project was completed on the water, in line the client’s environmental requirements.

The experience and skill of the Aquamax crews along with the low water volumes utilised, were key to pulling off this very demanding project.
