Combined IMR (offshore inspection surveys and freespan rectification by rock placement) in the the Strait of Gibraltar Pipelines and the Balearic Pipelines.

The objectives of the survey are to establish and document the condition of the pipelines. The survey activities are summarised as follows:

— conduct an ROV visual inspection of the pipelines and rock dumps. (For SoG pipelines, ROV shall be able to handle strong currents),

— establish/confirm the position, length and height of free-spans,

— detect, record and document all areas of damage,

— detect, identify and document debris adjacent to the pipeline,

— record and document the condition of the pipeline’s cathodic protection,

— inspect and document condition of crossings and any associated rock berms,

— document the seabed/pipeline and seabed/intervention/pipeline configuration,

— acquire a continuous ROV-based MBES DTM along all pipeline routes.

The events listing shall be accompanied by co-ordinates and correlated to the KP databases. In addition to the above survey activities it could be required to carry out light intervention work at locations identified during the survey as well as rock placement work for freespans rectification.
