Embodiments, including apparatuses, systems and methods, for attaching autonomous seismic nodes to a deployment cable. In an embodiment, an apparatus includes a seismic node having a direct attachment mechanism configured to directly attach the seismic node to a deployment line, the direct attachment mechanism being configurable between an open and/or unlocked position and a closed and/or locked position to release and retain the deployment line.

The present invention discloses a locking device for a marine anti-collision ball traction rope, comprising a lock body, a rope hole, a lock cavity, a lock head and a rope guide hole. The present invention has a simple structure. By enabling the traction rope to pass through the rope hole, enabling the rope to bypass the rail and pass through the rope guide hole, and enabling the traction rope to pass through the rope locking hole, the traction rope forms a bending. The traction rope exerts a pulling force, so that the lock head swings toward the side wall of the locking cavity and realizes self-locking. The traction rope is firmly stuck on the rope locking tooth claw. The anti-collision ball can be quickly fixed on the rail; the lock head swings toward the opening of the locking cavity, and the traction rope can be pulled for length adjustment.

An adjustable tethering system is disclosed that includes a primary line, a secondary line, and a capsule. The secondary line is wound about the primary line to form a frictional locking arrangement that resists translation of the secondary line along the primary line when the secondary line is tensioned. The capsule can be manipulated by a user to selectively release the frictional engagement between the primary and secondary lines, thereby enabling controlled transition of the system from a secured state to a state in which the secondary line can translate along the primary line.

An adjustable tethering system is disclosed that includes a primary line, a secondary line, and a bail release feature. The secondary line is wound about the primary line to form a frictional locking arrangement that resists translation of the secondary line along the primary line when tension is applied. The bail release feature is operable to be manipulated by a user to reduce the constriction of the windings about the primary line, thereby enabling controlled transition of the system from a secured state to a state in which the secondary line can translate along the primary line.
