DNV GL revises shaft alignment rules

摘要

The regulatory update is based on the first phase of the JDP, which was done in cooperation with The Swedish Club, Norwegian Hull Club, Gard and Skuld. The intention was to test the potential influence of EALs on failures in stern tube bearings. The JDP already entered the next stage, where oil film forming capabilities, mixed/boundary lubrication behaviour and lubricant degradation will be further scrutinized, the norwegian-german society announced during Nor-Shipping in Oslo. For now, the updated rules applying to newbuildings are effective since 1 July.
