Triumph of meticulous planning at Kinneil

As part of the Enhanced Gas Separation Project (EGSP) at BP Kinneil in Scotland, we undertook the movement of a 450-tonne module from Immingham on Humberside to the Kinneil site at Grangemouth. Less than two weeks later the large module was landed on its foundations to bring an end to a hugely successful operation that was over two years in the planning.

bp-kinneil-3.jpgThe primary objective of the project was to allow the Kinneil gas plant to process crude oil with a higher gas to oil ratio. During the FEED it was agreed that a modular approach would be adopted, maximising work off site and providing schedule assurance. 

From the onset, there was close co-ordination between BP and our teams based in Reading, Immingham and Grangemouth to overcome the key challenges:

  • Weight control - critical to ensuring that bridge loadings along the route and trailer stability limits were not exceeded. The module weight had to be carefully monitored throughout. It was weighed accurately using calibrated load cells prior to sail-away at the module yard
  • Installation sequence – a second, smaller module was shipped to site and installed first. It was temporarily raised by about one metre using climbing jacks so that it did not interfere with the trailers delivering the main module. This required very careful planning during the engineering phase
  • bp-kinneil-2.jpgRe-configuration of trailers at site - the trailer configuration from Grangemouth docks to the site was governed by the width of the Avon bridge. The trailers had to be reconfigured at site to accommodate the spacing of the foundation plinths
  • Site ground conditions - existing conditions along the roads at site were generally poor and had to be upgraded along major sections to accommodate the wheel loading from the trailers
  • Transport through the PetroIneos refinery – this needed close co-ordination between the BP and PetroIneos owners, but this meant that any disruption of fuel tankers leaving the Grangemouth refinery could be minimised.
“My gratitude goes to all the people involved in the move as well as those who designed and built the units, Amec Foster Wheeler and Fabricom respectively. This is a significant step in delivering a successful project and realising the mission to start up these modules.”
