Shell Leman

To ensure the future production of the Leman field and others which are tied in to the Leman complex, there was a need to invest in an extra compression platform. The new platform will connect to the existing Leman "A" complex with a bridge. The extension of the Leman complex is a part of the Shell ONEgas project.

The topside is designed by engineering firm IV Oil & Gas and Royal HaskoningDHV is involved as Health, Safety & Environment (HSE) consultant. It comprises two gas compressors, one a two-stage low pressure and the other a one-stage high pressure, both gas-turbine driven, with scrubbers, coolers, fuel gas treatment, and other equipment. The design phase of this new platform has started in 2012 and the completion of the project will be March 2014.

The studies executed by Royal HaskoningDHV are:
  1. General HSE Engineering support
  2. Writing HSE Design Plan and HSE Design Philosophies
  3. Performing Hazard Reviews (HAZOPs, HAZID, Dropped Objects Assessments, Noise, etc.)
  4. Perform Fire and Explosion hazard assessment studies
  5. Perform Computational Fluid Dynamics (CFD) modelling for vent dispersion and explosions
  6. Escape, Evacuation and System, Survivability Assessment (EERA/ESSA)
  7. Update Safety Case and perform Safety Critical Element identification and Performance Standards review

Shell UK Limited is the leading operator in the UK sector of the North Sea, exploring for and extracting natural gas and oil. Shell is responsible for about 11% of the U.K.'s total gas and oil production. The gas produced at Leman flows towards the Bacton Shell terminal where it is conditioned for sale to the U.K. market.
