Method for analyzing workable environment conditions of engineering ship

Abstract

The invention discloses a method for analyzing workable environment conditions of an engineering ship. The method comprises the following steps: step 1, collecting information about whether a ship works or not and a plurality of corresponding environmental information; step 2, carrying out datamation on the information of whether the ship works or not to obtain a sequence of whether the ship works or not; performing data processing on all the environment information to obtain a plurality of groups of environment data sequences; step 3, finding out a value range of the environmental data in an environmental data sequence, and dividing the value range into n threshold values; step 4, newly generating n groups of environment characteristic value sequences; and step 5, calculating Pearson correlation coefficients of the n groups of environment characteristic value sequences and the ship operation sequence to acquire a threshold value corresponding to the group of environment characteristic value sequences with the maximum Pearson correlation coefficient, namely, the workable condition of the ship corresponding to the environment is obtained. Whether the engineering ship can work under a certain environment condition in the future can be predicted.

Description

technical field [0001] The invention relates to an analysis method for operating environment conditions of engineering ships. Background technique [0002] Traditional offshore operations include cargo loading and unloading, navigation and towing, offshore hoisting, floating towing, jacket launching, laying of ocean pipelines, and other floating operations. participate. There are many types of offshore engineering ships, which are the basis of offshore construction operations and play a key role in the field of offshore construction. Therefore, the limiting environmental conditions of engineering ships' offshore operations are important research projects in the field of marine engineering. [0003] For decades, academia has done a lot of research on the methods of determining the operating environment conditions of various offshore operations and offshore vessels, and has fully identified various risk factors encountered in offshore operations. The maritime field has also ...

AI Technical Summary

Problems solved by technology

However, in the field of offshore construction operations, engineering ships are more diverse than other engineering equipment, have a wider range of operations, and are greatly affected by wind and wave loads. At the same time, there is a lack of engineering ships that complete major operations below the seabed mud surface. Therefore, the industry’s risk identification for the operation of these engineering ships is not complete, and there are no clear conditions to guide the operation of this type of engineering ships
