Autonomous Pipeline Survey

Ultrabeam Hydrographic teamed up with Unmanned Survey Solutions (USS) to conduct a pair of subsea gas pipeline inspection surveys in Northern

Ireland. Both companies are based in the UK and offer unmanned platforms as an alternative to traditional manned survey vessels.

The contract was awarded by Mutual

Energy, which wanted experience on how unmanned autonomous platforms can increase the knowledge of their pipelines while reducing risk and overall cost. “Mutual Energy con- tracted with Ultrabeam Hydrographic in August 2020 to perform inspection surveys of our Larne and Belfast lough crossing pipelines, key components of ent weather and sea states.
