In fracturing work safe range, if conditions are not met, then stopping this pressure break behavior operation, this fracturing work behavior sequence
Fracturing work result be 0；If it is satisfied, then this pressure break behavior operation is executed, after pressure break behavior operation is finished, by pressing
It splits system model and calculates this pressure break behavior operation to the fracturing work interference parameter of ship, and by fracturing work interference parameter
It exports to ship motion model；It then proceedes to judge whether to next pressure break behavior operation, repeatedly with this, until the pressure break
All behaviors operation in operation behaviour sequence, which is performed both by, to be finished, and the corresponding fracturing work knot of the fracturing work behavior sequence is obtained
Fruit；The corresponding fracturing work result of pressure break behavior sequence is exported to evaluation module；
Evaluation module carries out safety and effectively to the fracturing work results of all pressure break behavior sequences under same marine environment
Property evaluation, obtain pressure break behavior sequence optimal under the marine environment；By the optimal pressure under ocean environment parameter, the marine environment
It splits behavior sequence and its fracturing work result, evaluation result is exported together to knowledge store module and stored, and by human-computer interaction mould
Block is shown.
2. marine ship fracturing work DECISION KNOWLEDGE as described in claim 1 obtains system, which is characterized in that the ship behaviour
It include dynamic positioning unit and ship motor performance unit as module；
Wherein, the ship real-time attitude parameter that dynamic positioning unit is sent according to ship motion model, the posture for obtaining ship are inclined
Shifting amount；According to the marine environment interference parameter that attitude of ship offset, virtual simulation environment module are sent, generation is distributed in ship
The operating parameter of the Powered Propulsion equipment of surrounding, eliminates attitude of ship offset；
When dynamic positioning unit cannot completely eliminate attitude of ship offset, then start ship motor performance unit；Ship fortune
Dynamic operating unit is according to attitude of ship offset, the marine environment interference parameter of virtual simulation environment module transmission, dynamic positioning
The operating parameter for the Powered Propulsion equipment that unit generates generates ship main thruster operating parameter and vessel position Gesture operation
Parameter eliminates attitude of ship offset.
3. marine ship fracturing work DECISION KNOWLEDGE as described in claim 1 obtains system, which is characterized in that the evaluation mould
Block is after obtaining fracturing work result corresponding to all fracturing work behavior sequences under same marine environment, first by pressure break
The fracturing work behavior sequence that job result is 0 is deleted；Then according to the state of ship, fracturing work efficiency to the marine environment
Other lower fracturing work behavior sequences carry out multi-attribute Decision-making Analysis, obtain the optimal fracturing work behavior sequence under the marine environment
