摘要

apparatus for mounting or dismounting a capsule sensor, method for attaching sensor caps to a seismic cable on a vessel and method for detaching the sensor caps from a seismic cable on a vessel during seismic cable recovery an apparatus and methods for loading and unloading sensor caps (9) into or out of seismic joint pipes (5) forming part of a seismic cable (19) to be distributed or retrieved via a a vessel (18), the apparatus comprises: a trolley (3) capable of holding at least one capsule sensor (9), the trolley (3) is movable back and forth in a direction corresponding essentially to the direction longitudinal (24, 25) of the seismic cable (19); a support structure (12) for the trolley (3); a coupling mechanism (7) for coupling the trolley (3) to a joint tube (5); and at least one insertion / withdrawal mechanism (8, 11) for inserting and withdrawing the sensor caps (9) into or out of the gasket tube (5). 1/1
