Patent ID: 10605935

Abstract:
A system for ocean bottom sensing for performing geological survey. Herein the system comprising a cable further comprising a cable jacket (9), at least one optical fiber (6), and a plurality of detectors enclosed by the cable jacket (9). The latter including at least a first and a second detector (1, 2), the at least first and second detector (1, 2) comprising at least one intrinsic fiber optic sensor (3x, 3y, 3z, 3h, 3g, 3t). The detectors are communicatively connected to the at least one optical fiber (6) for allowing interrogation of the intrinsic fiber optic sensors (3x, 3y, 3z, 3h, 3g, 3t) and the cable jacket (9) has substantially a same cross-sectional diameter (D) and same outer shape at the at least first and second detector (1,2) and in between said first and second detector (1,2).
