Marine 6 Marine Applications Where Specialty Lubricants Pay Off

When specialty lubricants are properly matched to specific applications, the payoff can far exceed the cost of the lubricant and the expense of carrying it in inventory.

That’s because specialty lubricants can handle extreme conditions encountered with specialized equipment onboard modern vessels. Here’s how specialty lubricants can improve efficiencies and reduce the total operating costs when properly applied:

  1. Anchor handling winches
    To increase the life of the gear set, select a lubricant with high viscosity, good adhesion and protection of the entire tooth flank. A lubricant with a base oil viscosity at 40°C of 16,500 mm2/sec can easily be applied using automatic spray systems, immersion bath or circulation lubrication systems.
  2. Wire rope coverage
    To extend the life of wire ropes on board vessels, the lubricant must be able to seal in the lubricant applied during production of the rope, protect against corrosion and have minimal water wash off loss. Functionally, this feature minimizes wash off loss, maximizes corrosion protection and reduces friction generated between wire strands. It also reduces lubricant consumption and application costs. With good anti-wear properties, at low speed and under high load, the product may also be suited for open gears on deck cranes.
  3. Electric motor shaft bearings
    High speed shafts benefit from a lubricant that can minimize vibration, reduce internal friction and provide long-term protection. A low noise rolling bearing grease for long-term lubrication comprised of ester oil, a polyurea thickener and special additives is recommended. A highly homogenized formulation that contains very low amounts of impurities will also reduce low vibration and extend bearing life.
  4. Cold weather operations
    At low temperatures, hydraulic systems require a fluid that remains within viscosity limits to protect pumps and hoses under pressure — yet still provides lubrication during warm weather. High VI ester based hydraulic fluids may also meet the environmentally acceptable lubricant requirements of the EPA’s Vessel General Permit.
  5. Compressor oils
    To lubricate moving compressor parts, dissipate heat and form a seal edge between the rotor and the casing, polyalphaolefin (PAO) oils have ideal properties — thanks to very good oxidative stability that extend oil change intervals and minimize oxidation residues.
  6. Discharge manifolds
    Discharge manifolds on petroleum, chemical and LNG tankers require a bearing lubricant that can withstand the aggressive operating environment associated with these liquids. A lubricant formulated using PFPE base oils and PTFE thickener allows for operation in extreme temperatures, and is resistant to aggressive media.
