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
海上單點(diǎn)系泊輸油系統(tǒng)，是指系泊在系泊點(diǎn)的油船，隨著風(fēng)、浪和海流的變化而繞著單點(diǎn)自由回轉(zhuǎn)，從而始終地處于風(fēng)、浪、流合力最小方向的系泊輸油系統(tǒng)[1]。（剩余3760字）
