Abstract： In this paper， based on the actual situation of swivel device of single point mooring system for 300，000-ton oil tanker developed by the author’s company， and comprehensively considering the special requirements of offshore single point mooring oil transfer on swivel device bearing， the environmental load borne by swivel device bearings was calculated and analyzed， and the technical type demonstration and bearing capacity verification were carried out. Finally， the bearing type of the oil transfer rotary joint for complex sea conditions was determined.

Key words： single point mooring;  swivel;  environmental load;  bearing selection

1     引言

海上单点系泊输油系统，是指系泊在系泊点的油船，随着风、浪和海流的变化而绕着单点自由回转，从而始终地处于风、浪、流合力最小方向的系泊输油系统[1]。（剩余3760字）
