Design stages
To minimise the total elapsed time of a project, engineers submit drawings for your approval at different stages of the project. On the basis of the preliminary Vendor Documents, an engineer prepares an initial Draft drawing. This Draft drawing consists of an initial design scheme, including all basic dimensions, and is presented for approval. The objective of the Draft drawing is to prevent project slowdown due to an erroneous basic design.
When this basic design is approved, the engineer develops a detailed design consisting of a For Approval drawing. The For Approval drawing consists of a detailed design with an overview of the applicable welding procedures, tolerances and welding details. The detailed For Approval drawing is also submitted for approval.
Structural calculations, as well as the Inspection and Test Plan, are prepared. After the design has been approved, the required materials are organised and procured from permanent, recognised and reliable suppliers.
