The hydraulic oil used within the Side-Power Hydraulic Stabilization and Thruster System is critical to the reliable operation, efficiency, and longevity of the hydraulic components. Selecting the correct hydraulic fluid ensures proper lubrication, heat dissipation, corrosion protection, and consistent system performance under varying operating conditions.
This article provides the manufacturer’s hydraulic oil specifications and recommendations for Ocean Alexander vessels equipped with Side-Power hydraulic systems. The information below is reproduced from the Sleipner (Side-Power) Hydraulic System Installation, Start-Up, User and Service Manual and should be followed whenever servicing, topping off, or replacing hydraulic fluid.
Always use clean, uncontaminated hydraulic oil that meets the specified viscosity and performance requirements. Mixing different oil types or using fluids that do not meet the manufacturer’s specifications may reduce system performance, accelerate component wear, and may affect warranty coverage.
Important: Before adding or replacing hydraulic oil, verify the correct fluid specification for your vessel and ensure the hydraulic system is depressurized. All service work should be performed in accordance with the Side-Power service manual and Ocean Alexander maintenance procedures.
