PRODUCT UPDATE • Coatings & Corrosion Control employees, Isotrol can be applied by brush, roller, airless spray or dipping, and has a shelf life of up to seven years. The coating prevents deterioration by repelling moisture and encap- sulating existing rust, and surface preparation is minimal, involving no sanding, just the brushing off of flaking rust.

Used in conjunction with aklyd paint

Isoguard to provide ultraviolet protection and additional durability, the coatings system is guaranteed for up to 15 years and can report- edly be used as a shop primer on new surfaces.

Aqua-Dyne Unit Performs Tank

Cleaning

Aqua-Dyne Inc.'s new magnetic rotary clean- er was designed for cleaning and coatings removal on ship hulls and the inside and out- side of tanks as small as 50 ft. (15.2 m) in diam- eter. The unit's 30-in. diameter deck can be dis- assembled into two sections for insertion through tank manways as small as 18 inches in diameter. The rotary cleaning head is attached to a two track, hydraulically-driven carriage that moves and positions the unit. The car- riage also contains a proprietary magnetic holding system that holds the unit against the side of the tank/ship.

The unit requires a hydraulic unit and waterjet pump to operate, and is reportedly capable of handling flows up to 20 gallons per minute at pressures of 40,000 psi.

ABS Connects Coatings With Double-

Hulled Tanker Performance "Early reports indicate that coatings in the ballast spaces could become the key concern in the operation of double hull tankers," ABS

Senior Vice President Dr. Donald Liu advised delegates at an Intertanko event held recently in Athens. His observations are based paper he authored, titled Double Hull Ta.

What We Have Learned. The paper was w based on extensive owner feedback and a pilation of ABS survey and engineering re}

Although acknowledging some inconsi cies, the paper suggests growing evidence the quality and maintenance of coatings sh be a primary area of concern in double-hv tanker operation.

This finding is supported by an operatic database of ship performance that is being c piled by the class society.

In-service reports indicate that even wl most of a coatings application appears to p form well, breakdowns on free edges, in hi£ stress areas and on stringers and internal i tings within ballast spaces often take plat "These localized breakdowns are occurrii after periods as short as three years," said E

Liu, adding, "Other evidence is beginning 1 suggest that corrosion rates of the underdec plating in uncoated tanks can be two to thre times the normal expected rate." ABS source: concluded that while operational experience regarding coatings reliability varies widely, more attention should be paid to coatings tech- niques while double-hulled tankers are in the design stage, specifically in the areas of tank accessibility and ventilation.
