Practices by Discipline

This Practice provides guidance for the engineers who are designing circular platforms in accordance with PIP STF05535, Vessel Circular Platform Details, and for the engineers who design the vessels to support these vessel platforms. It describes the design basis for the platforms detailed in PIP STF05535 and circumstances that should be considered before using PIP STF05535. A table showing the platform design loads for the vessel clips is provided. The table should be used to check whether a vessel requires reinforcement to receive the platform loads.

This Practice provides fabricators with standard details for circular platforms for vertical vessels. This Practice describes the requirements and the design details for fabrication of circular vessel platforms including ladders and railing. PIP STE05535, Vessel Circular Platform Detail Guidelines, a guide for use by engineers who are providing the circular platforms in accordance with this Practice and for use by engineers who are designing the vessels to support these vessel platforms, is available on the PIP web site or from the PIP office. PIP STE05535 provides information to engineers about the design basis of the platforms, circumstances that should be considered before using this Practice, and a table showing the platform design loads for the vessel clips. Table 1 in PIP STE05535 should be used to check whether the vessel requires reinforcement to receive the platform loads.
