Oceanographic Cables

Research Cables

Cortland manufactures fiber-optic research cables that supply power to instruments at the bottom of the sea, allowing researchers to study-in real time-what is going on at the bottom of the ocean from the comfort of their offices.  They allow live images to be brought to the researcher’s PC. We offer a full range of plastic material options for our small diameter research cables.

Sampling Cables

Cortland manufactures synthetic fiber rope sampling cables to aid in obtaining water samples for a wide range of clients. Our small diameter, lightweight sampling cables are used to lower a sample collecting system into the water and retrieve it. These applications are non-metallic, which increases the accuracy of the sample.  Cortland also offers a full range of plastic material options for this fatigue-resistant application. Cortland sampling cables are preferred because of our variety of braiding and extrusion processes. 

Benefits / Features
  • Non metallic
  • Small diameter
  • Fatigue resistant
  • Lightweight
  • High strength efficiency
  • Both braiding and extrusion processes offered
Magnetometer Cables

Cortland manufactures magnetometer cables for oceanographic mapping surveys for a wide range of clients. Our cables are preferred for their wide operating temperature range and ability to be used in shallow or deep water. Whatever your specific requirements, we can design and develop lightweight, small diameter, high-strength cables which offer lower elongation at varying depths. 

Benefits / Features
  • Lightweight
  • Small diameter
  • High strength
  • Lower elongation
  • Wide operating temperature
Applications
  • Marine geophysics
  • Treasure hunting
  • Research
Electro-mechanical Mooring Systems

Cortland designs, manufactures and supplies compounded synthetic mooring lines, including electrical and optical components, using the latest high modulus synthetic fibers.

Proven for tsunami warning applications, we have the capacity to provide cables with varied buoyancy, to reduce fatigue or extend life; integrate compliant sections, with varied stretch properties; and also incorporate sections with low elongation and high strength.  All with no diameter change, offering cables that are consistent and easy to handle. 

Whether it’s adding separators for fish-bite protection or extruded profile jackets to reduce strumming, all of Cortland’s electro-mechanical cables can be custom-designed and built to suit the needs of your particular project. 

Benefits / Features
  • Compounded constructions
  • Varied properties, yet consistent diameters
Applications
  • Marine geologists
  • Oceanographers
  • Meteorology
Tow Cables

Cortland offers cables for wide tow multiple streamer data acquisition applications, which demand high tow strength, minimum cable diameter, and minimum weight. Cables consist of a range of single or grouped electrical cores and fibre optics. Our designs offer the most compact electrical and fibre optic assembly diameters and can be offered with either synthetic fibre strength member or steel wire armour packages to achieve the highest strength, smallest flexible cable on the market. These variants can be produced in long continuous lengths.

Customer specific cable and mechanical armour terminations can be provided as part of Cortland’s scope.

Cortland can apply fairings as a solution to the adverse effects of strumming / vibration which can be set up as the cables are towed through the water behind surface vessels. Fairings are generally applied as braid with extensions along two or more axes of the cable formed by weaving a filament yarn about one or more insulated conductors with the yarn serving to anchor the conductors on the cable and extending outwardly to form fairing hairs. Generally the braid material is polyester although other materials and variants can be offered.  Solid fairings or customer free issued fairings can be fitted if required.

Finalized packages include full testing in accordance with industry standards.

Benefits / Features
  • Combination options of power, signal and optic layout / sizing
  • Choice of component configurations including singles, pairs and quads
  • Choice of optical fibres with various MM SM options
  • Special thin wall core insulation optimizing cable OD’s
  • Highest strength steel wire while maintaining ductility
  • Choice of high modulus fibre strength layers saving weight on wire armoured variants
Applications
  • Seismic tow cable assemblies
