    Inspection and repair on FLENDER G1-750VY gearbox

    Scope of work:

    - Inspection propulsion gearbox, Flender GA 845.

    During inspection not, all bearings and gears could be inspected.

    Small leakages were observed around the gearbox at the seals and on the OD-box.

    The generator shaft bearings show wear, scratches and small indentations. The conditions of these bearings can be considered as non-acceptable.

    Small steel particles were observed in the filter elements.

    During the last oil sample there was found water inside the oil of the gearbox. Water in the oil can reduce the lifetime of the bearings and the gears.

    Inspection and repair on RENK SHH 11 1135,1/760 gearbox

    This client from Norway came to us with this RENK SHH 11 1135,1/760. We inspected the gearbox and performed a repair. After a succesful testrun we shipped the gearbox back to the client.

    Upon arrival on the vessel in Rotterdam, preparations were made to disassemble the gearbox. Only upon arrival at anchorage in Scheveningen the disassembly could be started.

    The gearbox showed no signs of serious damage or wear, beside normal wear on bearings and impact marks on the gears, from running without load. The intermediate shaft driven-end bearing however was found heavily damaged, most likely caused by slipping of the rollers/bearing.

    It is suspected that
