A wide range of solutions are available to suit the geometry of individual platforms and the requirements for reeling either cable only, or complex arrays with variable diameters and handling properties.
MacTaggart Scott's facilities include outdoor and indoor full-scale test areas for proving trials, demonstrating endurance in seawater under full drag loading and even emergency cable cutting at speed under load. The Company has recently expanded its capability with a long array test tank and a dedicated noise and vibration test area.
Advanced spooling systems
Computer-controlled and mechanically-integrated spooling systems cope with layer change and cross-section steps. Control consoles provide manual recovery modes using closed-circuit television facilities as well as a wide range of information from deployed length and velocity to cable loading profiles.
Multiple Array Types
The towed array handling systems are design to accommodate multiple array types, even arrays with varying diameters of tow and acoustics modules. MacTaggart Scott work with the customer and the array supplier to test the full system before it is installed on board, so de-risking the at sea testing and acceptance phases of the programme.
