Affection of turnout anchorage on throughput capacity of fairway in coastal bulk port

With the increase of port scale,the fairway greatly restricts the port’s capacity.Therefore,turnout anchorage is proposed to improve the throughput capacity and decrease the investment.This study establishes an Arena-based coastal bulk port navigation operation system simulation model;then determines the optimal site of turnout anchorage and the affection of the quantity of turnout anchorage on the throughput capacity of fairway.Finally,the results show that the throughput capacity of fairway is improved evidently by setting turnout anchorage,and the optimal site of turnout anchorage is the midpoint of the fairway.
