Detailing the aspects relevant to the tail shaft surveys for oil lubricated tail shafts
DNV GL issued a Technical Update regarding the aspects relevant to the tail shaft surveys for oil lubricated tail shafts.
The harmonized Rules for Fleet in Service published by DNV GL on the 2nd of November 2014 apply to all vessels in the DNV GL common production system NPS. These were published as an integral part of the DNV GL merger and from the synergy derived from the technical and systematic perspectives in legacy DNV and GL rules.
The contents are located in Pt. 7, Ch. 1 of the legacy DNV Rules and Part I-0, Sec. 5 of the legacy GL rules.
Tail shaft survey requirements for oil lubricated arrangements, a critical survey scheme from a DNV GL classification perspective, have been revised in conjunction with the harmonized Rules for Fleet in Service. They retain a strong technical base to achievemultiple survey options for ship owners and the desired classification objectives. Due diligence on risks associated with withdrawal of tail shafts during routine surveys were provided during formulation of the survey schemes.
DNV GL’s Technical Update details the aspects relevant to the tail shaft surveys for oil lubricated tail shafts from both technical and systematic perspectives and with special focus on how ship managers and owners may derive the optimum benefits from them.
In addition, the prominent changes made to legacy DNV and GL rules which applied before November 2014 are highlighted for the benefit of the owners.
