Protecting seismic survey cables

2022-03-10
■ Where any cable or hose connects to a structure,normal movement during operation (dynamic loading) or forces incurred during installation and retrieval (static loading) can cause catastrophic failure of the cable or hose, at the termination point. The failure mode can be through collapse,rupture of internal lines or even rupture of the external layers leading to escape of the contents to the environment.This can happen as the result of a single event or be caused through fatigue damage over time.
■ Bend limiting devices are provided to protect the cable or hose from these situations and perform the following functions:
▲ Maintain the manufacturers recommended minimum bend radius (MBR) during the life of the project
▲ Provide a suitable load path from cable or hose, to fixed structure
▲ Reduce point loading at the termination to an acceptable level
