Core Grouting completes Trinidad and Tobago subsea pipeline rectification
Core Grouting Services, an Acteon group company, has completed a pipeline free-span rectification project in Trinidad and Tobago.
BISHOPSTOWN, UK –Core Grouting Services, an Acteon group company, has completed a pipeline free-span rectification project in Trinidad and Tobago. Core installed grout bags at several subsea locations beneath a pipeline at water depths of 120 to 150 m (394 to 492 ft).
Ivan Harnett, managing director, Core, said, “Our client identified more than 50 locations on its subsea 24-in. pipeline where free spans required correcting with grout bags. We designed and manufactured customized grout bags to fit the free span locations, and the installation of the grout bags at the identified locations brought known free spans under the allowable design limit.
“Because of the water depth and remote location, the grout bags were positioned by ROVs. We also supplied bag deployment frames, which enabled the bags to be lowered to the seabed and successfully positioned by the ROV.”
