10. INSTALLATION PROCEDUREThe flowchart presented in this section indicates the planned sequence of operations. Theimplemented offshore sequence of operations may have to be revised to accommodateunforeseen site or weather conditions, in order to avoid unnecessary vessel stand-by or siteaccess conflict.

Since the task plans are principally live working documents, the task plans may be revised offshoreat the time of the installation, following discussions between Offshore Manager, Field / ProjectEngineer and Client representative onboard. Any procedural changes will only take placeaccording to SAIPEM Management of Change Procedure.
