Development of requirements for protection against resonance in piping of ship systems
Abstract
The article presents the main results of research work on the development of requirements for monitoring the vibration state of pipelines of ship systems. The analysis of various technical regulations (ISO and GOST R standards, industry standards for the oil and gas industry and the shipbuilding industry, the Rules of Classification Societies) in terms of the requirements for pipeline vibration control has been carried out. Various types of damage to ship pipelines due to vibration exposure have been considered and analyzed. It has been shown that under operating conditions, a set of static and dynamic loads acts on the mechanisms and pipelines of ship systems, and the combination of the impact of these loads determines the level of vibration in the system "mechanism — pipeline". A criterion for ensuring the protection of ship pipelines from the occurrence of resonance and recommendations for detuning from resonant frequencies has been proposed. Requirements for the control of vibration of ship pipelines have been developed and formed to be included in 1.4, Part VIII "Systems and Pipelines" of the Rules for the Classification and Construction of Sea-Going Ships.
