Trenching

Cathie Associates draw on more than 40 years combined experience in pipeline and cable trenching projects to deliver solutions associated with the difficult business of trenching and burial. We work for trenching contractors to assist with burial assessments for specific equipment, and for owners/operators or EPC contractors to select appropriate trenching equipment. We assist our clients to set realistic targets for burial depth and trenching rates. We advise on burial risk and can propose burial depth criteria to achieve a specific target reliability. Cathie Associates offers solutions in:

  • Burial depth requirements and burial risk (probabilistic or deterministic approaches)
  • Trenching and burial assessment
