Array configurations and longer umbilical lengths have extended the required capacities, components, towing loadings and dynamic factors of the air gun umbilical products offered by Cortland.
Cortland umbilicals can be supplied with a single central air hose or multi-hose, depending on gun configurations and air volumes. Layers or sub-assemblies of single or grouped electrical and/or fibre optic components can be added for power and control of firing, hydrophone, pressure and depth sensor equipment.
In terms of strength, Cortland offers the most robust and compact umbilicals, using steel armoured or aramid fibre strength layers, protected by extruded sheathing of various material types.
Umbilicals can be fully terminated, ensuring the successful transfer of the tow loads whilst offering protection to the electrical, optical and pneumatic interfaces. All the main industry standard electrical connectors can be supplied, such as AG Geophysical, Veam, Anphib , Harting, Terracon and Cannon, as well as terminated deck cables.
Cortland's termination packages integrate to the majority of current end use control system equipment and include full testing in accordance with industry standards.
