Drew Marine Corrosion

Solution Protects Aging

Ballast Tanks

Ashland Chemical Co.'s Drew

Marine Division just introduced a solution to the challenge of protect- ing aging ballast tanks from rust.

Drewgard WB corrosion preven- tative is a water-based coatings system that reportedly meets class society requirements for hard-film protection at a reportedly lower cost than other hard coatings, without necessitating drydocking.

The product is formulated as an air-dry wax sulfonate emulsion using a proprietary process for replacing typical solvents with water as a carrier. This emulsifies the wax components in combina- tion with a synthetic polymer to form a hard film barrier that bonds to the surface of metals, prevent- ing oxide formation and rust as long as the barrier remains in place. The film reportedly displays good flexibility and will not crack or peel.

Norshipco Conducts

Paint Removal Project

Hammelmann Dockmaster U.S. representative Milt Lindgren recently called MR/EN to report that the first full-scale use of auto- mated, ultra high pressure (UHP) paint removal equipment in the

U.S. was scheduled to take place at

Norshipco in Norfolk, Va., from

July 21 to 24. Seariver Wilmington was the ship involved in the pro- ject.

According to Hammelmann lit- erature, UHP water blasting is an ecological alternative to open dry blasting and is used for cleaning, coatings removal and paint strip- ping in a variety of industries.

Specifically for the marine indus- try, Hammelmann supplies a range of equipment, from jetting guns with rotor jets to semi-auto- matic Dockmaster ship stripping systems complete with waste water recovery capabilities.

Compact Power for

Marine Applications

Hagglunds Drives is a supplier of hydraulic drives for the marine and offshore industry and tough industrial applications.

Hagglunds Viking motors have been used on winches on board ships for more than 30 years working in tropical heat or arctic cold. In tough marine environments, day after day, year after year.

Now we have introduced the Compact motor, a smaller and lighter motor who is tailored for applications like these. The hydraulic motor is attached directly onto the drive shaft or winch drum without any gearbox or foundation, ft can be controlled fully across its entire speed range, and provides full torque from standstill to maximum rotational speed.

Furthermore, it is insensitive to shock loads and tough environments, and it stops right when you want it to, thanks to it's extremely low inertia. Direct hydraulic drives is about as maintenance-free as you can get.

Extremely powerful. And still extremely compact.

The new line of COMPACT motors has a power to weight ratio of around 1.5- 2.0 kW/kg (0.9-1.2 Hp/lb). For the first time there's a motor that lives up to the true meaning of the concept of compactness.
