UTEC NCS completes offshore West Africa AUV projects for Saipem

Offshore staff

ABERDEEN, UK – Acteon's UTEC NCS Survey has completed AUV operations for a number of Saipem projects offshore West Africa.

UTEC NCS has done pre-lay and as-laid surveys using its Gavia AUV systems on the Mafumeira and Litchendjili fields, offshore Angola and Congo. Using a GAVIA AUV, an anchor pre-lay side scan sonar survey was carried out in the Mafumeira field to clear the way for barge operations alongside the Mafumeira Norte platform.

Pipeline route and barge anchor corridor pre-lay surveys were carried out in Litchendjili in water depths of 3 m to 12 m (10 ft to 39 ft) using the GAVIA’s mult-beam and side scan sonar. The GAVIA was re-deployed to carry out post lay operations along the pipeline corridor to inspect for free spans and other anomalies.
