Performance and Suitability Analysis of Drillstring Heave Compensator for Float Platform

Taking a drill string heave compensator with a maximum compensation load of 4 500 kN and a compensation accuracy of 90% as an example, the performance parameters, advantages, and disadvantages of drill string heave compensator of different structure types and working principles, and their engineering adaptability were analyzed. According to different operation requirements, a comparative analysis was carried out from the aspects of operation efficiency, structure center of gravity, drill floor layout, operation cost, operation, and maintenance, etc., to provide principled guidance for selecting drill string heave compensation schemes in the design of deepwater drilling rigs.
