Abstract

This paper considers the issues and theoretical aspects related to improving the design of maritime tethered systems (MTSs) with flexible links (FLs) using underwater towed systems (UTSs) as an example. That allows them to be used in the early stages of design by implementing the principles of Shipbuilding 4.0 and BIM technologies. Such regimes have not previously been described by existing mathematical models (MMs). The expected result of the current study is a significant decrease in the cost of different resources. At the same time, the basic reliable results of design solutions could be obtained already in the early stages of design. The theoretical basis of the proposed method for improving the design of MTS with FL is the improved design concept (IDC) for MTS with FL while the tool base of the method is a special modeling complex (SMC). The use of IDC along with SMC at the research (pre-prototype) design phase reduces the number of MTS design stages. The proposed method to improve the design of MTS with FL, based on the MM that notates the dynamics of MTS FL and MTS with FL, makes it possible to investigate different modes of operation of almost all MTS classes. That allows devising the recommendations for predicting possible operational loads in order to design their elements. At the same time, there is an opportunity to improve the existing methods for calculating and designing MTS with FL with the required properties and parameters, and to bring them to the level of engineering application. The application of SMC at the pre-prototype design stage makes it possible to avoid the use of physical modeling of the operational regimes of MTS with FL associated with the full-scale testing on the high seas

Highlights

It is expected that the introduction of the Shipbuilding 4.0 principles in the shipbuilding industry brings the future closer, creating new values and putting forward new requirements to reduce production and operating costs while improving production efficiency
A way out of this situation could be the approach proposed in paper [10], which is to develop a mathematical models (MMs) of the flexible links (FLs) element dynamics, which makes it possible to take into consideration the large movements of FL within maritime tethered systems (MTSs)
The improved design concept for MTS FL and MTS with FL is to improve the design of MTS, making it possible to take into consideration the internal and external factors of the environment affecting the operation of FL, and to create advanced MTSs

Summary

Introduction

It is expected that the introduction of the Shipbuilding 4.0 principles in the shipbuilding industry brings the future closer, creating new values and putting forward new requirements to reduce production and operating costs while improving production efficiency. Manufacturers will follow the course of transferring production from outdated plants of the past to a data-rich, optimized, and efficient future of the “smart” plant. The key to this transformation is the data to generate a synchronized flow of digital information that connects even the most disparate global supply chains into a single digital enterprise. Additional categories are added to it such as time, plans, cost They make it possible to calculate and determine parameters for the project modeling processes even before it is implemented. Technology, and design methodology using the principles of Shipbuilding 4.0 and BIM technologies could prove relevant for improving design activities in shipbuilding
