Preface
Offshore platform is a kind of truss structure that is higher than the sea surface and has a water platform surface. It is a land-like area that is convenient for people to walk in the sea when working at sea. It is used for production operations or other activities, such as oil extraction on the seabed, offshore Construction work, etc. In recent years, as offshore surveying and mapping projects have become increasingly large-scale and the inevitability of operations in harsh natural environments has gradually increased, offshore operation platforms have become one of the main equipment for ocean development, and they also play an extremely important role in offshore oil and gas development. Roles.
3D visualization, as a necessary technology for building digital industrial fields, provides users with a complete picture of virtual construction operations, which is convenient for managers and construction personnel to see the entire system while also observing local details. With the help of 3D configuration , three-dimensional animation as the head, and information display as a supplement, the whole dynamic process of maritime safety operations is simulated, so that everyone can understand the offshore operation process and working environment more intuitively.
Interface introduction and effect preview
This scenario uses the HT technology of Hightopo software to realize that the offshore platform uses booms and hooks to carry out operations such as lifting, moving, and placing for offshore facilities. Helicopters and ships are mainly used to cooperate with offshore platforms for related construction operations. At the same time, with the display of operating environment parameter information, the three-dimensional visualization effect of offshore operating platform construction is presented.

System analysis
In the past, our economy was affected because we did not have a strong enough industrial background to exploit marine resources such as oil without equipment. With the rapid development of science and technology, coupled with my country's extremely rich marine resources (including more than 10 billion tons of offshore oil reserves), my country's strength has continued to grow, and various types of offshore platforms have been created, such as the Blue Whale series independently developed by China , Is the world's most advanced ultra-deepwater double rig semi-submersible drilling platform. The offshore drilling platform is called the "mobile land" and is mainly composed of an upper platform, a lower floating body (matted pontoon) and a middle column. The platform is equipped with drilling, power, communication, navigation and other equipment, as well as safety rescue and personnel. Living and other facilities.
1. Working principle
The mat enters the sea by filling water, leaving only part of the column and upper platform on the sea surface, and the top drives the drilling. After the oil is drilled, it can be quickly transferred to the oil production. After the drilling is completed, the water in the mat is discharged, and then Move to the new well position. The drilling construction process includes three stages: pre-drilling engineering, drilling engineering and completion operation. The following figure shows the main processes:
In fact, with the advancement of technology and the demand for advanced equipment in marine engineering, different types of offshore engineering platforms have begun to appear, making offshore operation platforms used in many fields and aspects:
- Laying, constructing, testing, and dismantling water and underwater facilities, such as: docks, embankments, bridges, underwater cables, underwater tunnels and other public facilities;
- Rescue ships in distress, salvage sunken ships and sunken objects, clean up marine pollutants, and protect the marine environment;
- Carry out marine and meteorological observations, water ripple measurement, geological surveys, scientific research and other activities that affect the safety of water traffic;
- Exploit offshore resources such as oil, natural gas, combustible ice, etc.;
- Used for construction operations that affect the traffic safety of navigable waters or the navigable environment.
The application of manipulators is one of the core functions of offshore operation platforms. It can be used for dispatching equipment, maritime rescue, assisting in the construction of offshore facilities, etc. It is one of the most important production and safety equipment at sea. It has the characteristics of simple operation, good braking performance, strong versatility, strong wind resistance, and repeatable operations. It can replace people to complete some complex and heavy handling tasks or assist people to achieve high-risk tasks. It can also replace Workers complete large-scale production tasks, which greatly improves labor productivity, guarantees the personal safety of workers, and saves human resources. Therefore, it is widely used in many industrial industries such as machinery manufacturing, construction operations, and logistics systems.
2. Information bar display
By changing the rotation angle along the Y axis, the rotation process of the three information bars of wind/wind direction at different speeds, safe operation days, and drilling activation process is realized. Offshore operations are high-tech, high-input, and high-risk jobs. The working conditions are more complex and severe than land operations. In addition to being affected by the same weather factors as land operations, they are also affected by the special marine environment, such as ocean currents, Severe weather such as tides and storm surges.
Therefore, offshore operations can establish contact with the local meteorological department, bind the content of the information bar according to the environmental conditions of the engineer on the day, grasp the dynamics of the marine climate in time, and ensure the safety during construction.
3. Aircraft driving track
The offshore helicopter is a means of transportation during the normal operation of offshore operating platforms, mainly used to transport materials, handle emergencies and transport personnel. The flight mode and route of the aircraft can be specified according to the custom trajectory, the starting and ending positions of the aircraft, the flight status and other attributes, combined with the animation function in HT to achieve the flight effect.
4. The fluctuation of sea water
By changing the sea water, the height position of the ship and the random change of the transparency of the waves, the wave state of the sea surface is presented. Ships are mainly used to cooperate with offshore operation platforms to complete offshore operations, and users can also establish a connection between the two by themselves.
to sum up
With the development of science and technology and the progress of society, offshore operation platforms have gradually been widely used, such as in marine survey, resource collection, environmental care, scientific research, etc., in the face of various complex oceans such as wind, waves and currents. The operating environment and the requirements of maritime safety and technical specifications, etc., have positive significance for various types of offshore operations. They are indispensable equipment for people’s marine work and provide a stable workplace for marine operations. Sex is self-evident.
HT combines three-dimensional animation with industrialized fields, so that each facility in the scene has a more flexible form of expression and intuitive and vivid visualization effects. The vivid animation presentation is convenient for engineers to quickly understand and formulate the construction process of offshore operations, and present it in real time and intuitively. The working environment information for offshore construction can assist managers to make accurate decisions in time, and achieve scientific and effective management of the entire construction project.
