Oil Recommendations
WARNING
▪
Using oil other than specified by KONGSBERG MARITIME may cause malfunctions when
maneuvering the vessel. This may cause personal injury and equipment damage. Before
using other brands, please contact Kongsberg Maritime.
▪
Do not mix hydraulic oils
Note!
Oil temperature must be limited to 70°C.
For vessels operating worldwide, KONGSBERG recommend oil according to ISO-VG 68. Viscosity
Index of minimum 110.
Only use oil approved and recommended by KONGSBERG.
The performance of the unit is highly depended on the viscosity of the oil. The surrounding
temperatures of the hydraulic components when operating at extreme temperature conditions,
tropic or arctic waters, must be considered when selecting type of oil.
The oil must be checked regularly for contamination and the relevant oil company and KONGSBERG
recommendation for oil change must be followed. Change the oil if components in the hydraulic
system are broken down or if significant color or smell change occurs. If laboratory tests show a change
in the number of additives or a high number of insoluble particles in the oil, oil change is required. If
the water content exceeds 300ppm, a separator or similar for water removal should be applied.
The following hydraulic oils are approved and recommended by Kongsberg Maritime:
