Redesign of existing pipelines for enabling regular inspection
Maasvlakte terminal, Rotterdam, the Netherlands

Between the Maasvlakte Oil Terminal (MOT) and the Britisch Petroleum Refinery Rotterdam (BPRR) two 42' crude oil pipelines need regular inspection to assess integrity. Therefore, parts of the pipeline needed to be redesigned. But construction had to be executed with minimal loss of capacity, requiring at least one pipeline to remain in service at any time. To replace the 42' pipelines an excavation of almost 9 meters was required in order to construct the pipeline welds. This construction required a temporary replacement of the helicopter platform and helicopter shed. The pipelines were not sweet, therefore neoprene spheres were used to close off the pipeline for crude oil and gasses in order to execute hot works.
