| Abstract: | The guided waves technology has been successfully used to screen offshore pipelines.Riser splash zone could be successfully screened from top-side position using the Wavemaker technology.Underwater pipelines could be screened using the sub-sea technology developed by Guided Ultrasonics Limited,which allowed the screening of tens of meters of underwater pipelines from a single location. |
