Mechanical Completions, Pre-Commissioning and Commissioning

Mechanical Completions, Pre-Commissioning and Commissioning

During the project engineering phase in Detailed Design stage, ADSIE are able to check and review all the applicable documents for commissioning engineering with focus on technical preparation for execution of Mechanical completion (Pre-Commissioning) and Commissioning.

ADSIE will provide all the necessary

Check lists
Test sheets
Data Base, etc. as per the breakdown of the project into Commissionable Sub-systems

Mechanical Completion


Mechanical Completion is considered by ADSIE to be the interface between construction and commissioning and includes all interfaces to the systems whether the systems are module or plant wide. Terminology differs from Client to Client and Project to Project. ADSIE understanding of Mechanical Completion may also include pre-commissioning depending on the Clients' contract terminology.

Mechanical Completion operations (Multidiscipline Pre-commissioning) will verify the construction works based on the project specification and manage the relevant punch lists (A and B Categories) accordingly. This operation covers all the static tests of equipment up to issuance of Ready for Commissioning (RFC) Certificates for each sub-system to be compiled in the Mechanical Completion Dossier.

ADSIE goal is to reduce costs by advising and assisting the Client in how to achieve successful Mechanical Completion by using techniques which have a proven track record in delivering effective and efficient results.

Commissioning & Maintenance

Commissioning is considered to be the energisation of mechanically completed equipment and systems including dynamic trials of systems and sub-systems and providing Ready for Start-Up (RFSU) certificates, compile in commissioning dossier and handover of respective data giving proof of mechanical completion and commissioning whether it be onshore or offshore.

Some examples include the running and entire testing of the power generation systems, testing of emergency shutdown and control systems and dynamic trials on oil and gas export systems prior to load out to minimize the offshore or site scope.
