Problems solved by technology

However, this form of avoidance area close to the channel cannot be used as a conventional solution: the too small turning diameter makes it impossible for large ships to enter the avoidance area autonomously, and several tugboats are needed to assist to complete this operation, which is very difficult, especially for Oil tankers, higher requirements for safety

Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings.

[0048] Such as Figure 1 ~ Figure 3 As shown, a method to reduce the cost of passing through the main channel of the oil terminal includes the following steps:

[0049] Step 1: Select the location of the avoidance area

[0050] The following two points should be paid attention to when selecting the location of the avoidance area in the port area:

[0051] 1. The location of the avoidance area should be close to the main channel, but it should not affect the normal passage of ships in the main channel;

[0052] 2. The avoidance area should choose waters with good water depth conditions to reduce dredging costs.

[0053] During the process of site selection, several site selection schemes can be listed at the same time, including the original scheme of not building additional avoidance areas.

[0054] The avoidance zone refers to an anchorage near the main channel. W...

Abstract

The invention discloses a method of reducing oil jetty main channel passage costs, characterized by comprising the steps of: S01, selecting a plurality of avoidance area positions meeting conditions and establishing a plurality of avoidance area site selection schemes, including a site selection scheme of not building out avoidance areas, i.e., a scheme of departing from port along a main channel; S02, respectively establishing simulation models for site selection schemes, and outputting time parameters; and S03, through outputting the time parameters, performing economic analysis on each site selection scheme, calculating the comprehensive passage cost C of each site selection scheme, and selecting a site selection scheme of lowest comprehensive passage cost C. The method determines the comprehensive passage cost of each avoidance area site selection scheme through the simulation models and economic analysis, and selects a scheme of lowest comprehensive passage cost as an optimal scheme so as to reduce ship passage costs as much as possible, and improve crude oil harbour district channel passage capabilities.

Description

technical field [0001] The invention relates to a method for reducing the passage cost of the main channel of an oil wharf, and belongs to the technical field of shipping and transportation. Background technique [0002] The continuous and rapid development of China's economy and the acceleration of industrialization and urbanization have directly driven the demand for bulk raw materials such as crude oil, coal, ore, and led to a rapid growth trend in the bulk cargo business of Chinese ports, among which the demand for crude oil is extremely huge. However, there is a gap between my country's crude oil production and consumption, and the gap is widening year by year. The contradiction between crude oil supply and demand has become increasingly prominent, and the balance between crude oil supply and demand has to be met by increasing imports. [0003] Considering the capital and knowledge-intensive characteristics of crude oil berths and huge sunk costs, how to increase the th...
