ABSTRACT:
A ship is disclosed for seismic or geophysical exploration. The ship is provided with a pair of jibs which are supported between upper and lower decks for pivotal movement between a retracted position between the decks and an outwardly pivotted position extending laterally outward from the sides thereof. The jibs are each of a reinforced construction of triangular cross-section. A plurality of motor-driven reels are positioned at intervals along the length of each jib for reeling out and in a cable supporting a seismic exploration gun or other geophysical exploration device. A trolley mechanism is supported for movement longitudinally of each jib to carry seismic guns to and from the point of connection to the respective cables. Each jib includes a catwalk to permit access to the operating parts thereof during use.
