“…The variety of operational tasks has led to the complexity and further improvement of the developed SW that describes the dynamics of MTS FL. In the study of the towing process, 38 parameters were initially taken into consideration by SW, then 58 parameters were taken into consideration [19]; 67 parameters were taken into consideration by SW when studying the emergency modes of MTS operation when the FL collided with a marine object (Fig. 3, 4).…”

“…The proposed SMC, which is based on the MM and SW that describe the dynamics of MTS FL (and MTS with FL) [19], makes it possible to improve the existing methods of calculation and design of MTS with FL and bring them to the level of engineering application. It also makes it possible to investigate different modes of MTS operation, to obtain the values of forces operating on the FL (and in it) and working bodies of CW, to assess the real destructive efforts in the FL and MTS, to develop recommendations for predicting possible loads, to reduce the masssize characteristics of ship deck devices [20].…”

“…CW simulation of the dynamics of FL and MTS with FL is developed in the Delphi system based on an algorithm for solving the system of equations in the MM of the MTS dynamics [19]. A working window of the software on a computer screen contains windows for setting the parameters' values (from 37 to 67) for MPS and 4 parameters of the algorithm.…”

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

The paper deals with issues connected with the behaviour of a streamer cable towed by a survey seismic vessel when the cable undergoes a strike triggered by collision with an underwater moving object. The consequences of such collisions may be both threat to the life of marine animals or damage to underwater units and large economic losses suffered by vessel owners. The risk of such collisions has increased over the last years as a result of increased offshore seismic survey operations. Therefore, a towed streamer should be very robust. To assure its robustness, we should know the deformation mechanism of a single streamer cable. This in turn requires the development of an appropriate mathematical model of such a phenomenon.In particular, the paper presents the characteristics of seismic survey vessels and streamers; an analysis of collisions that have occurred in the past; a statement of the problem, and a computer-aided system supporting simulation of the cable behaviour. To obtain all the necessary design parameters regarding the deformation mechanism of a streamer cable, we set up a dedicated computer-aided system that supports their calculation.
