Vibration Control Design of Reciprocating Compressor Packages in Offshore Platform

The offshore platform reciprocating compressor unit, which is installed on a flexible platform structure, is prone to large vibrations than land-based units. Consequently, the maintenance and rectification expenses caused by vibration are high and the consequences are serious. In order to control the vibration of reciprocating compressor unit on offshore platform, taking the vibration control design of reciprocating compressor unit of an offshore platform as an example, the pulsating unbalanced exciting force of the unit is reduced through the analysis of airflow pulsation; the vibration level of the unit equipments and pipelines are controlled through the mechanical vibration analysis; the vibration analysis of the unit bottom skid and platform support structure is carried out to reduce the vibration level of the unit and platform structure. The analysis results meet the requirements of the standard, which can provide technical methods and references for vibration control design of offshore platform reciprocating compressor units in the future.
