Pipeline Inspection in West Africa

At Prism Energy, we have decades of experience operating on pipeline projects across the North Sea and beyond. Our project managers are actively involved in various pipeline projects, including pre-commissioning, pigging, inline inspection (ILI), and decommissioning.

Below is an overview of a pipeline inspection scope we completed in West Africa.

Description

A progressive cleaning campaign was executed across two pipelines in preparation for an ILI (inline inspection). Phase one involved the pipeline running between the wellhead tower and FPSO, while phase two involved the pipeline running between the FPSO and onshore receiver station.

Challenges Successfully Managed

The project required overcoming several logistical constraints, including daily boat transfers to the platform and restrictions on onshore travel to daylight hours. Weather conditions added complexity, alongside the need to operate on an unmanned installation and address anchor damage sustained by one of the pipelines. Fluctuations in the pipeline operating parameters and unexpected damage to a cleaning pig added further complexity to the scope, requiring greater review and caution.

These challenges were successfully managed due to our experience in pig launching procedures and our ability to review data alongside the physical condition of the returned pigs. Additionally, our background in international operations allowed us to develop productive relationships with local teams.
