船舶水尺计重误差分析与控制

Error Analysis and Control of Draft Survey for Shipping

水尺计重是一种通过船舶六面吃水进行观测求得船舶相应排水量,计算所装卸货物的计重方法,它一般适用于价值较低、衡器计重困难、大宗散装固体的计重。随着国际贸易的发展,散装货船的日趋大型化,且货物价值不断提高,因此水尺计重的准确度要求越来越高。为了提高水尺计重的准确度,作者对其过程中的可能产生的误差进行分析,并加以控制,进而减少因误差而带来的损失。

Draft survey is a kind of based on the observations of six sides to draft, obtained corresponding displacement ships, calculate the weight method, loading and unloading of goods it generally applies to the lower value, difficult by scale weight, weight of bulk solids. With the development of international trade, the large-scale trends of bulk carrier, and the value of cargo, the accuracy requirement of draft survey is higher and higher. In order to improve the accuracy draft survey, the arthors analyze the possible error and control, then reducing the loss due to error.
