The aim of the present document was to duly facilitate the process of standardization of the applicable technical documentation that is required for the subsea field development projects. The document is covering the documentation normally generated in the procurement, engineering and construction phases of the project.

It is also listing the project documentation relating to the operational phase as applicable to the various equipment and systems. The publication also details the essential documentation with the purpose to reduce the overall volume of the documents being transferred between all parties involved.
