Pipelines

Landfall projects in Bacton, UKFrom major product gathering schemes to large diameter oil, gas and multi-product transmission pipelines, Mott MacDonald’s specialist engineers have in-depth know-ledge of the design, engineering and operational criteria relating to overland and subsea pipelines.

For projects spanning the globe we’ve designed complete gather-ing and transmission systems with all associated pumping, compression, treatment, booster, block valve, pressure reduction/metering and trap stations.

Pipeline rocksaw at workInnovative and cost-effective value engineering, surge cal-culations, corrosion analysis and network hydraulic modelling are just some of the skills we offer in addition to mainstream engineering. We’re fully con-versant with all design require-ments – especially corrosion protection and mitigation to prevent crude solidification, hydrate formation and hydrogen induced cracking. Our offshore experience covers every facet of subsea pipeline design including trenching, laying, landfalls and operational stability measures. We’ve even researched vertical top tension risers behaviour in deepwater, resulting in design guide-lines increasing the feasibility of exploiting new deepwater fields.
