World class experience in commissioning with a fully integrated service from pre-commissioning to final handover and signoff

We understand how important first oil or first gas dates are to our customers, so we always aim to better these dates safely. Wood Group has over 30 years of experience of successful hook-up and commissioning (HUC) projects around the world. Our success is built on working with the best people and using our integrated Work Planning System and Completions Management System.

Defining the work

At this vital stage we clearly determine the operating systems and limits, and system handover sequences. We identify inspection test records along with other documentation to be included in the Completions Management System and prepare commissioning procedures.  This way we create the best possible start for our people and our customers.


Using the base hook-up work scope and a work breakdown structure, we develop a strategic execution plan, from which we prepare construction work packs. Our work packs and job cards contain all we need to complete work that passes thorough testing and inspections.


The most effective construction method to complete the hook-up of a facility  is by area. However, for the commissioning team to commence their work, they need a system or part of a system completed. Getting the best balance between these competing demands is where our experience and planning come into their own. The safety of personnel and avoidance of danger to the environment is paramount.


The key to a successful hook-up is speedy transition from construction into commissioning, allowing the earliest possible testing and proving of the functionality of the systems. Once final certification for the mechanical completion and commissioning of each stage of hook-up is completed and verified, the work is then as-built and closed out.

Management systems

Our Work Planning System and Completions Management System ensure that the correct people and materials are onsite at the correct time. They hold all the information required to successfully manage a project through mechanical completion, pre-commissioning, commissioning, readiness for start-up and handover to operations.
