QUALITY CONTROL
GENERAL RULES FOR IMPLEMENTATION
Quality is first the concern of the Operator: reliability of the Plant (to ensure steady revenues) will be directly linked to the Quality achieved during all steps of project performance.
Quality has to be prepared and the objectives defined during the Pre-Project Phase.
Quality can be checked and sometimes measured, but the most efficient way to obtain the best quality is to pay for it: “offer peanuts, you get monkeys” is always true.
Selecting professional contractors with a good knowledge of the specificity of the job is one essential step.
Agreeing a reasonable price for the contract is a key aspect

QUALITY CONTROL
ENGINEERING ACTIVITIES
THE KEY TO QUALITY CONTROL: TECHNICAL COORDINATION
EXAMPLE : THE CONTROL of OFFSHORE PLATFORMS WEIGHT
Offshore platforms are designed to be installed by one or a few very specific equipments: derrick barge, launch barge…
Each lifting equipment has a limited capacity: 650 ST, 1000 ST……..2500 ST…..
Launch barges are also limited by the weight and dimensions of the module to be installed
Therefore, the strict control of the weight and dimensions of the offshore platform has to be organized all along the engineering phase.
74
QUALITY CONTROL
CRITICAL EQUIPMENT
PROJECT QUALITY SURVEILLANCE PROCESS
For fabricated equipment, Quality is controlled through:
Quality audits of Manufacturer, and guidance on Quality issues
Quality Control assessment at manufacturing sites
The auditing work at the workshop can be undertaken by specialized Inspection agencies representing the main Contractor who , very often , does not have the qualified personnel available at site. Upon request, the inspector shall be given access to all relevant QA/QC documentation. He shall then produce an inspection report mentioning all observed deficiencies for contractor/operator attention and further remedial action.
For certain important items, the Operator may participate to shop inspection
75
QUALITY CONTROL
CONSTUCTION PHASES
Some aspects to be checked and constantly monitored:
Raw materials: sand, water, aggregates, steel….
Concrete quality checking after pouring
Welders qualification records
Material fabrication certificates
Welding equipment and materials…
Lifting equipment certificates
Installation procedures….
Dimensional survey of fabricated items
…
