Vehicle Load Analysis For Locations Interfacing With KOC Underground Assets And Services For The Umm Al‐Hayman Wastewater Project

Vehicle Impact Load Analysis:

The main objective of Vehicle Impact Load Analysis for pipeline is to ensure the object’s integrity and stability during the maximum impact acting on the surface. The dynamic loads are applied on the object surface and its material behavior will be studied precisely by using Finite Element analysis methods. Based on the material type, the relevant software application will be placed as per project requirements.

Project Brief:

Kuwait Authority for Partnership Projects, State of Kuwait, hereinafter called COMPANY, have awarded the “Umm Al Hayman Wastewater Project” of which the DBO Scope is being executed by a CONSORTIUM made up of WTE, CANAR and KCCEC., hereinafter called M/s DBO CONSORTIUM

M/s. DBO CONSORTIUM has requested M/s. NAPESCO to carry out a Vehicle Load Analysis of surrounding KOC asset and services whilst the pipelines are laid for the Wastewater Transmission System (WWTS) and Treated Sewage Effluent Transmission System (TSETS).

The new pipeline transmission system interfaces with the KOC underground asset and services at 40 locations. The heavy vehicular movement in the interface locations are envisaged by the construction team during pipeline laying activities. M/s DBO CONSORTIUM has contacted National Petroleum Services Company (K.S.C.P) for engineering support to analyze the vehicle impact on the existing KOC underground asset and services. M/s iFluids Engineering FZE provided the Engineering consultancy services to study and analyze the impact on the underground components due to this heavy Vehicular movement.

Activities involved in Vehicle Impact:

  1. Input Analysis and Data Validation.
  2. Modelling of Pipeline in STAAD PRO Software (FEM Method).
  3. Assigning of properties for the modelled pipelines and other components.
  4. Applying of Support system according to the soil parameters given.
  5. Application of loads on the Pipes with Self-weights, Seismic loads & Vehicle Load.
  6. The actual loads are compared with design loads which is calculated by using the Standard ASCE 7-16 Minimum design loads and associated criteria for buildings and other Structures.
  7. The allowable bending stress and allowable shear stress is evaluated from yield stress of pipeline material.
  8. The stress is analyzed on different depths of pipes in 40 KOC interface locations.
  9. The actual Stress value is analyzed with Pipeline’s maximum allowable stress limit.
  10. The summary of results are represented and recorded in the report format both pictorial and numerical results.

Individual location wise reports have submitted for client reference and permit validation.
