Description
Technical field
The present invention relates to marine seismic prospectiong technical field, more particularly to a kind of air-gun array extension and retraction system and method.
Background technology
Typically by artificial excitation's seismic wave, several by pulling behind investigation vessel are equipped with detection for marine seismic prospectiong
The collection towing cable of device receives stratum back wave.Investigation vessel is used for engineering investigation and middle-shallow layer Seismic exploration and development.Conventional prospecting
Ship is generally equipped with Seismic Source System (air cannon and array), system for acquiring seismic data, towing cable control system, navigation system etc..
Air-gun array draw off gear is the equipment of folding and unfolding Seismic Source System, is the important component of investigation vessel.
The pneumatic gun seismic source array draw off gear of investigation vessel has two kinds at present：One kind is flexible floater rifle battle array draw off gear, separately
One kind is rigid floater rifle battle array draw off gear.
The ground way mode that flexible floater rifle battle array draw off gear uses.Ship on flexible floater rifle battle array draw off gear
Ground way is installed in oceangoing ship structure, many rollers are installed on ground way, has chain link to be connected with soft formula floating drum below roller.
When carrying out rifle battle array folding and unfolding, flexible floater and rifle battle array slip into water neutralization from the inclined slip of stern and reclaimed from water.In order to subtract
Damage of the inclined slip to positions such as rifle array 1 system cable, tracheaes in small release and removal process, flexible floating body rifle battle array folding and unfolding dress
The inclined slip design for putting afterbody must be reasonable, can typically take the stern construction form of single chute type and double chute types.
During using flexible floater, the height of usual slideway is 3m.
Rigid floater rifle battle array draw off gear needs special telehoist to complete air-gun array folding and unfolding.Rigid
Installed in Ship Structure above floating body rifle battle array draw off gear it is scalable go out stern main extensible canopy crane be used for will it is rigid float
Cylinder rifle battle array is stretched out outside ship deck and cloth is put into the sea；Be also equipped with the both sides of extensible canopy crane can transverse movement it is auxiliary
Extensible canopy crane, effect are the hard floating drum rifle battle arrays that dump is withdrawn.When carrying out rifle battle array folding and unfolding, major-minor extensible canopy crane is used
Realize folding and unfolding, the storage operation of rigid floater and air-gun array.Can effectively it be reduced using rigid floater rifle battle array draw off gear
Slideway is to air gun pigtail line cable, the damage of tracheae and colliding with for air gun during air gun folding and unfolding.But the disposable fund needed is thrown
Enter that big, the requirement to auxiliary equipment and ship deck height is strict.
Both the above rifle battle array folding and unfolding mode is required for being arranged on hull according to design requirement in investigation vessel design-build,
Construction period is grown；Make that subsea strata investigates experiment, remaining time does other sections for certain time in scientific surveying ship etc. 1 year
For the ship for learning experiment, permanent other scientific investigations for occupying hull space, influenceing research ship of conventional rifle battle array folding and unfolding mode meeting
Experiment.
