Earthquake operations The equipment of the underwater cable dragging includes the elastic section of the cable, the working cable, the carrier, the spacing rope, the auxiliary buoyant , etc., and each equipment is connected to each other, dragging on the rear of the ship, dragged on the rear of the ship.
The towing mode in offshore seismic survey operations determines the force relationship between lead-in cables, deflectors and the ropes (spur lines) that connect them,
Neutrally Buoyant Tether Cables gain buoyancy with thermal rubber (TPR) sheath materials which are extremely flexible with good mechanical resistance. Expanded foam polyurethane (ExPU) gives extremely low specific gravity filling and jacket compounds. Thin wall insulated conductors also assist in reducing weight and diameter. Copper coated alloy conductors can also be used. We can offer prototype short length-ed to enable companies to trial run.
