PRE/POST TRENCHING & BACKFILLING OF CABLES, UMBILICALS & PIPELINES

Our highly experienced team has trenched pipelines/cables in all corners of the world over the years. We have developed several innovative trenching systems to cater for specific site conditions found all around the world. Our systems are capable of trenching sandy soils, hard clays, and cemented soils. These systems have the ability to trench cables and pipelines of all types and sizes while operating in water deoths ranging from ultra-shallow to deep waters.

 

We utilise advanced technical instrumentation for controls and progress monitoring to provide commercially viable, efficient and precise solutions for both Pre and Post trenching operations.
