Tube Tech were able to mobilise urgently, unblock the pipeline and remove the deposit by using:
- Tube Tech 'hot tapped' into aa non-pressurised system and removed the stuck pig by a bespoke "drilling" method.
- Once pig removed the remainder of the line was cleaned to production standard using a variety of cleaning heads to suit heavy scale and other fouling characteristics.
- The pipeline was inspected before, during and after the cleaning process.
- Actual cleaning time was 1 week.
Tube Tech technicians were also able to retrieve the lodged pig in the final 30m of the pipeline.
