Abstract

The present invention relates to a field data-based ship maneuvering simulation system and, more specifically, to a field data-based ship maneuvering simulation system capable of minimizing a problem occurring during ship maneuvering in an extreme offshore environment since a virtual system is constructed on the basis of field data measured by various sensors provided in a ship, thereby enabling a real ship maneuvering environment to be exactly simulated. A ship structural design is validated by calculating the physical characteristics such as a bending moment, a shearing force, buoyancy center and load center of a specific ship to be simulated, and the movement of the ship and the state of the components such as an engine, a rudder and a thruster are monitored with high accuracy in real-time such that an administrator or an operator monitors the state of the ship and promptly takes actions for alerts according to the monitoring, thereby preventing, in advance, an accident occurring in the ship maneuvering environment. In addition, a ship component manufacturer, which manufactures ship components to be applied to specific ship, performs simulation in a real ship maneuvering environment after components are mounted in a specific ship during a component design step before a high-priced test product is made, such that the durability and stability of the ship components are predicted, thereby reducing costs and time for manufacturing the ship components and enabling a high reliability component verification standard to be presented. Furthermore, real offshore plant environment is shown to students who have few experiences with offshore plants and engineers such as designers of component manufacturers, so as to allow the students and engineers learn the physical characteristics of the ship components to be applied to the specific ship, thereby allowing field experience to be accumulated and providing great help for learning.

Description

Ship data simulation system based on field data

The present invention relates to a ship navigation simulation system based on field data, and more particularly, to build a virtual system based on field data measured from various sensors installed in a ship, and to prepare a real ship navigation environment and a main component of a ship or a ship. By being able to simulate the load as it is, the present invention relates to a ship data simulation system based on field data for minimizing problems in ship operation in extreme marine environments.

Offshore plant is designed, manufactured, transported, installed, operated, maintained and dismantled in terms of process, and offshore support vessel (OSV) is transported, installed, operated, maintained, modified and dismantled in this process. A ship used for stages.

2 is a view that the marine support ship (OSV) is supporting the operation of the offshore plant. In other words, offshore support ships are used to supply goods to offshore plants, to help transport, install, remodel and dismantle offshore plants, and to be used for drilling or transporting oil or gas.

The movement of marine support vessels depends on the actual environmental factors such as blue, tidal currents, wind, and location, and each major factor is measured by sensors such as gyro, wind vane, VRU, Doppler, GPS, HPR, etc. do.

The measured values are then processed and analyzed in the laboratory or analysis room with data on waves, wind, temperature and stress.

However, due to the characteristics of the marine support ship operating in the extreme marine environment, there is a high risk of safety accidents such as fatigue breakdown and grounding due to the deterioration of the ship life due to the deterioration of the ship's durability due to the Nether load and the fatigue load. By analyzing and identifying the cause only after an accident, there is no system that can monitor and predict these problems in advance.

To this end, it is necessary to evaluate the stability of the marine support vessel's movements and components at appropriate times from time to time. Therefore, field data for design and engineering can be accurately simulated at any time or in real time based on the actual operation data of the marine support vessel and predict stability and durability. You need a virtual machine based on that

The problem to be solved in the present invention is as follows.

First, the ship's structural design is verified by calculating the physical characteristics such as bending moment, shear force, buoyancy center, and load center of the specific ship to be simulated, and the ship's motion and the state of components such as engine, rudder, and thrust are high. By monitoring in real time with accuracy, the manager or operator monitors the ship's condition and promptly executes measures such as warning to prevent accidents in the ship's operating environment in advance.

Second, the ship parts manufacturer, which manufactures the ship parts to be applied to the specific ship, predicts the durability and stability of the ship parts by simulating them in the actual ship operation environment after installing the parts on the specific ship in the part design stage before making expensive prototypes. Its purpose is to.

Third, it is possible to show the actual offshore plant environment and learn the physical characteristics of the ship parts to be applied to the specific vessel to engineers, such as students and designers of parts companies who have insufficient offshore plant experience, to accumulate field experience and learn. I would like to help greatly.
