Description
Technical Field
The invention relates to the technical field of emergency disposal of hazardous chemical leakage, in particular to a simulation drilling method for emergency disposal of marine oil spill at a port.
Background
The port and the wharf are used as a bay and a coastal area, and the influence caused by oil spill pollution accidents is particularly obvious. At present, most of petroleum transportation in China adopts a marine transportation mode, ships can park in port wharfs for loading and unloading, most of port liquefaction chemical berths in China are mostly loaded and unloaded through connection of oil transfer arms, the oil transfer arms are special facilities for connecting ship side pipe orifices and wharf oil transfer pipelines, and the diameter and the configuration number of the oil transfer arms are set by full-hydraulic drive oil transfer arms configured in the wharf according to the size of the wharf. When severe weather, strong wind or overlarge sea waves occur, the ship can swing, so that the connected oil transportation arm is squeezed, the joint of the oil transportation arm and the ship is leaked, or a pipeline behind the oil transportation arm is squeezed and broken. The harm of oil overflow is very big, and when spilling oil and leaking to the sea, can be dispersed all around under the effect of surface tension, inertial force, gravity and viscous force, wherein gravity and surface force are the drive power, and inertial force and viscous force are the resistance. Not only causes seawater pollution, but also is easy to cause fire, and because of the flowing property of petroleum, on one hand, the petroleum is easy to flow into the sea to cause ocean pollution, on the other hand, the flowing fire is formed when the fire breaks out, so that the fire is more dangerous than the common fire, and the secondary accident of the surrounding environment is more easily caused, thereby causing huge property loss.
In order to enhance the emergency rescue and handling capacity of primary staff and commanders for field accidents, the traditional emergency drilling can simulate the emergency handling during oil spill at sea of a port to a certain extent, but has a larger gap with a real scene all the time. Because of the assumed oil spill accident, the limitation of the environment and the great limitation in experience, the participator cannot really feel the scene of the real oil spill accident to a certain extent, and cannot completely master the handling mode of the oil spill accident, once the oil spill accident really happens, because of lacking of the actual field experience, the participator often has great psychological pressure, operation misappropriation and even misoperation are caused, and further greater safety accidents are caused.
Through search, Chinese patent number ZL201710174221.4, the date of the issue: 12 and 14 in 2018, the name of the invention is: a simulation method for simulation training of oil spill accidents; the application comprises the following steps: 1) the method comprises the steps of using a three-dimensional modeling module to construct a simulation model of emergency strength and emergency resource equipment related to an oil spill accident, 2) using a port modeling module to construct a three-dimensional scene simulation model of a port around the oil spill accident, 3) setting an oil spill accident occurrence point in seawater of the three-dimensional scene simulation model of the port, using the set oil spill accident occurrence strength to perform dynamic simulation on the oil spill condition by an overflow information simulation submodule, using an emergency treatment deduction submodule to deduct a treatment process in a state machine mode according to the type, time and place of the oil spill accident occurrence, and finally storing the three-dimensional scene simulation model, the drilling process and the drilling training effect in a file mode. The application solves the problem that the conventional simulation method cannot carry out oil spill accident simulation training, can replace the conventional actual combat drilling at present, but the simulation drilling mode of the application is relatively not open enough, and the function is single, great limitation still exists in experience, once the oil spill accident really happens, the participants may still have great psychological pressure, and the actual oil spill accident cannot be well treated.

2. Technical scheme
To achieve the above object. The technical scheme provided by the invention is as follows:
the invention discloses a simulation drilling method for port offshore oil spill emergency disposal, which comprises the following steps:
1) accident scene simulation: firstly, carrying out 1:1, combining a Unity3D engine and a programming language to realize the interaction between a scene and a role, wherein the scene specifically comprises: fire water monitor, oil transportation arm, oil pipeline, oil containment boom, oil transport ship. The fineness of the equipment, process lines, etc. associated with the terminal area of the oil spill is based on the actual requirements to the extent that it is operational. Secondly, aiming at the problem that the petroleum has the flowing property when leaking, the petroleum can float on the sea surface when flowing into the sea, and the particle model has inflammability, accurately simulates the effects of petroleum flowing and flowing fire diffusion, and restores the process of leaking to diffusion.
The oil containment boom is the basis and key of the whole oil spill emergency action, and the oil containment boom can be timely distributed to effectively prevent the pollution range from being enlarged and prevent the oil spill from floating to directly influence the subsequent recovery and treatment effect. The invention utilizes the Bezier curve to process the deployment of the oil containment boom, so that the deployment of the oil containment boom is closer to the actual deployment shape of the oil containment boom, and the physical characteristic of the oil containment boom, namely the pull-up shape of the oil containment boom under external force, is simulated by using the classical mass point-spring model.
Specifically, the invention adopts a quadratic Bezier curve, formula (1) is a formula of the quadratic Bezier curve, wherein P0 is the starting point of the oil containment boom, P2 is the end point, P1 is a point on the perpendicular line between P0 and P2, the increasing step length of t in the formula is that the reciprocal of the distance between P0 and P2 is the first decimal, the initial position of P1 is just right to form an equilateral triangle with P0 and P2, P0, P1 and P2 are substituted into the formula to calculate the curve point, the invention uses a LineRender component in Unity to transmit the calculated point set into the LineRender to generate a corresponding curve, and simultaneously uses the LineRender component to endow the oil containment boom with corresponding materials, the curve processed in this way is more in the arrangement shape of the perpendicular line of the oil containment boom, when two ends of the oil containment boom are pulled by external force, the coordinate positions of P0 and P2 are updated, because the water resistance force makes the P1 slowly move along the original direction, the speed is about half of the average moving speed of the points P0 and P2, and the curve is calculated by repeatedly substituting the formula.

Most of the ports in China are liquefied and chemical berths which are mostly loaded and unloaded through the connection of oil transportation arms, and the oil transportation arms are special facilities for connecting ship side pipe orifices and wharf oil transportation pipelines. When severe weather, strong wind or overlarge sea waves occur, the ship can swing, so that the connected oil transportation arm is squeezed, the joint of the oil transportation arm and the ship is leaked, or a pipeline behind the oil transportation arm is squeezed and broken. The invention combines the reality, not only carries out simulation on the mechanical arm in a working state (the oil transportation arm is still under the normal condition), but also simulates severe weather, and utilizes numerical simulation to ensure that the oil transportation arm and the ship swing when encountering strong wind to reach a certain degree, the joint of the oil transportation arm and the ship leaks, or the strong wind causes the ship to swing to the direction of the oil transportation arm to be overlarge, so that the extrusion fracture of an oil transportation pipe behind the oil transportation arm is caused.
The invention specifically relates to a method for simulating the ship's swinging motion by gradually increasing the wind power of a wind component from 1 to 9 per second by a step t, when the wind power F is a certain threshold value Q, the ship sways with the wind, the swaying amplitude is simulated by combining the ship inclination angle and a certain displacement, the superposition value of the inclination angle is set as F/4, the mass representation value m of the ship is set as F/(2 m), when the maximum value of F is reached, the F is immediately attenuated to the threshold value Q, the amplitude is gradually reduced to 1 per second by the step t, when the wind power F is weakened to be below the threshold value Q, the ship starts to recover, the deviation angle and the displacement are recovered by speeds v1 and v2, and simultaneously a Character Joint component is added to the connection part of an oil transfer arm and the ship, so that the oil transfer arm swings along with the swaying to a certain degree, and the connection part of the oil transfer arm and the ship leaks, or the strong wind causes the swing amplitude of the ship to the direction of the oil transportation arm to be too large, so that the oil transportation pipe behind the oil transportation arm is extruded and broken.
The petroleum leakage and the fire caused by the petroleum leakage are greatly different from the common pollutant leakage and the fire, and the biggest characteristic is the flowing property, the particle model and the mathematical model are used for simulating and reducing the petroleum leakage and the caused flowing fire, in combination with the reality, the oil spilling drift model is used for simulating the diffusion effect when the petroleum leakage enters the surrounding sea area, the physical effect when the leaked petroleum floats on the sea surface is reduced, in combination with the simulation of the oil containment boom, the polygon cutting is used for preventing the floating petroleum from being diffused when the floating petroleum meets the oil containment boom, but when the oil containment boom is not well deployed, the petroleum continues to be diffused outwards from the gap.
The unity editor has built-in particle models, which describe the behavior of particles over a period of time. In order to better simulate the effects of petroleum flowing and flowing fire diffusion, the particle model is correspondingly set. In the process of simulating petroleum flowing, corresponding materials are firstly given to the particle model, and the particle model can be set to be influenced by gravity because of the flowing effect required, so that the particles are prevented from being shot into the air. Simulating flowing fire diffusion, firstly simulating the combustion effect of each flame by using a particle model, firstly endowing corresponding flame materials, then setting the emission speed of particles in the horizontal direction to be smaller, setting the speed in the vertical direction to be larger, not being influenced by gravity but being influenced by external force, simultaneously setting the life cycle to be smaller, then setting a plurality of ignition points, namely setting a plurality of particle emission points, wherein the diffusion effect uses ray detection, namely, rays are emitted from a set origin to the periphery for a certain distance, the origin is usually a leakage point, if no collision is detected, a flame particle emission point is generated at the intersection point of the normal perpendicular to the ground at the end of the ray and the ground, and the diffusion is stopped in the direction when the collision represents an obstacle.
The mathematical formula is shown in formula (2) and formula (3), wherein X1 and Y1 are the plane coordinates of the oil particles at the next time, wherein U, V represents the flow velocity component in the plane X, Y direction, and W is10The wind speed at 10m of the sea surface is uniformly set as the wind power value of the wind component, alpha is the wind and ocean current angle correction coefficient, usually 0.02-0.03, in the invention, 0.03 is taken, A is the wind direction, and the included angle between the wind component and the X direction of the world horizontal coordinate is set here. Δ t is the time step, here set to 1, Ex，EyThe coefficient can be measured or specified by related actual data, and floating diffusion of the oil on the sea surface is realized by continuously substituting the coordinates of the particles into the calculation of the next coordinate and moving the particles to the next coordinate. The invention simultaneously simulates the damage of people when the people are subjected to the heat radiation of the fire. The damage value of the flame in the system is set as H, the distance between the participator role and the flame is set as a set D, wherein D can be obtained by traversing all ignition points, so that the damage value is obtained by multiplying the reciprocal of an element in D by H, the damage value obtained by continuously subtracting the calculated damage value from the life value of the role, and the role is sacrificed when the life value is 0.
