Towing/Pushing Equipment TRIZ Cases

A trawl spreading device uses a bulb to generate hydrodynamic lift, reducing water resistance while maintaining spread.

Segmented hull modules with universal interfaces allow rapid reconfiguration for different worksites, reducing idle time and modification costs.

A hydrodynamic control device uses rotatable wings to adjust lateral and vertical streamer position without mechanical actuators.

Active motion compensation system synchronizes docking station with remotely operated vehicle using particle motion sensors.

A submarine tow-line system uses an auxiliary line routed through a sealed hull groove to transfer tension from the bow area.

A wing releasing system uses an actuator to detach wings from a navigation control device body.

Swivel joints accommodate differential vessel motion while maintaining a gas-tight seal during pitch and draft changes.

Asymmetric drag on a buoyant rotor rotates capture loops to passively latch unmanned surface vehicles, reducing mechanical complexity.

A sonar towfish antenna pivots from vertical to horizontal orientation to reduce bulk during retrieval.

Dual reel assemblies retract a surf rope above water to prevent propeller entanglement and drag damage.

An undersea steering vehicle adjusts the direction of a nodule collecting apparatus to follow a predetermined seafloor path.

Automated cable breakout assembly aligns tow ball connectors via cam rotation, reducing system complexity and preventing cable damage.

Mechanical rotatable bridle block resolves U-turn heading control by eliminating vulnerable electrical cables and reducing towing line stress.

A software-controlled deployment system adjusts winch and capstan lengths to hold seismic source arrays at precise inline coordinates during towing operations.

A tensioning frame positions a towed antenna array using water drag forces to maintain defined orientation relative to the water surface.
