After comprehensive testing, MAN Diesel has given general approval for the use of Vickers Oils bio-oils with its CP propellers.
Accordingly, Vickers biodegradable and non-toxic oils are now accepted by MAN Diesel for use within complete oil systems in the VB and VBS propeller range.
As such, Vickers bio-oils can be used both for the general gravity lubrication of sterntube bearings, and the lubrication of propeller hubs moving internal parts.
Jens Ring-Nielsen, senior manager for MAN Diesel Propellers, Gears & Aft-Ship Systems, says: “We are very pleased with the test results experienced with Vickers bio-oils. We are the first company able to offer our customers the opportunity of using environmentally friendly, biodegradable oils in their CP-propeller systems”.
The oils, which have undergone extensive testing, have the Vickers trade names HYDROX BIO 68 and HYDROX BIO 100. Additionally, another Vickers bio-oil is presently being tested for use with MAN Diesel's AMG-range of reduction gearboxes, and as hydraulic servo-oil for propeller pitch-setting.
The 'bio-lubricated' VB and VBS propeller range covers the power range from 1,000 to 30,000 kW - and hub series from 480 to 1,940mm in size. This corresponds with propeller diameters in the range of 1.8 to 8m.
