ExxonMobil marine , Belarus

U.S. EPA 2013 Vessel General Permit Compliant Stern Tube Oil

Product Description

Mobil SHC Aware™ ST Series lubricants are high performance, emulsifying stern tube oils for marine stern tube systems that meet the U.S. Environmental Protection Agency (EPA) 2013 Vessel General Permit (VGP) guidelines for "environmentally acceptable lubricants". Mobil SHC Aware ST Series emulsifies readily with seawater to form a stable water-in-oil emulsion that is adhesive and an excellent lubricant. It provides effective rust protection in the presence of seawater and the lubricating film is resistant to water washing so that corrosion protection is maintained for extended periods under severe operating conditions.

Features and Benefits

• Meets US EPA 2013 Vessel General Permit requirements for environmentally acceptable lubricants

• Can safely run with up to 20% water content emulsion

• Excellent load carrying capability and corrosion protection

• Compatible with most typical mineral oils used for stern tubes

• Good elastomer compatibility, it works well with many of the same elastomers used with conventional mineral oils

• Mobil SHC Aware ST 220 can provide effective leak control when seal damage occurs

Applications

• Marine stern tube systems, fin stabilizers, and certain controllable pitch propeller systems where spills or leakage could result in adverse environment impact

• In systems where readily biodegradable and minimally toxic fluids may be required

• Marine and mobile equipment operating in environmentally sensitive areas

• Circulation systems operating under mild to moderate service conditions
