Polish Register of Shipping has amended the requirements of Publication 45/P – Fatigue Strength Analysis of Steel Hull Structure due to the changes made to Common Structural Rules for Bulk Carriers and Oil Tankers.
Fatigue Strength Analysis of Steel Hull Structure is an extension of the requirements set forth in Part II – Hull of the Rules for the Classification and Construction of Sea-going Ships, as well as in all other PRS Rules, in which reference to the Publication has been made.
The fatigue strength standard, specified in the Publication, as well as the recommended calculation methods enable to assess whether the proposed hull design solutions satisfy the fatigue life requirements (usually the 25 year lifetime) and to correct, where necessary, the proposed solutions of various structural details.
The Publication contains requirements for the fatigue strength analysis of hull structures subject to variable in time (pulsating) stresses, induced by the inertia forces of cargo, ship structure and equipment due to the ship motions in waves and sea dynamic pressures.
The Publication was approved by the PRS Board on 28 July 2022 and entered into force on 01 August 2022.
