LDPE Wilton

2005 - 2006



The LDPE at Wilton, Teesside was to be the largest of its kind ever constructed. Commissioned at a late stage by the EPC to bring on track a project suffering from poor project control, our remit was to implement a workable schedule, through clear definition of the scope of work.


Unasys were contracted to mechanically complete a new polyethylene plant. We were engaged to provide and manage the electronic management system, having established the system definition, via system and sub-system analysis of design P&IDs. Unasys also prepared the basis for project execution, utilising in-house procedures and test sheets adapted for this specific project.


Recommended to SABIC, they sought to implement a dedicated team and application to maintain control of construction, testing, MC & commissioning.


  • Entering a project at a late stage complicates project delivery and swift implementation of corrective actions was required
  • In order to fulfil the client brief it was necessary to gain a quick understanding of the issues specific to this project, define and prepare a suitable schedule for completion which would include all passive as well as process systems

Unasys Approach

  • A dedicated team of specialists would liaise with all sub-contractors and vendors to facilitate co-ordinated completion
  • The benefits of the e-PM system together with the methodical controls and reporting systems were to be transferred to the client in completing the precommissioning scope of work


  • Intervention was pivotal in delivering successful completion
  • Some specialist staff retained post completion date
