Design of Offshore Structures Using STAAD - Pro and STAAD - Offshore

STAAD.Pro and STAAD.Offshore software are used to design offshore structures like jacket platforms by modeling them, assigning section properties and supports in STAAD.Pro, then importing to STAAD.Offshore to generate wave loads based on factors like wave coefficients and ship motions. Typical analyses involve modeling the structural frame in STAAD.Pro, defining custom or standard sections, and transferring to STAAD.Offshore to apply wave and transport loads.

Design of Offshore Structures using STAAD.

Pro and
STAAD.Offshore
STAAD.Pro is a general purpose structural analysis and design tool that is being used to design
offshore structures. STAAD.Offshore allows users create wave loading and transport loads on
offshore structures. It can handle pipes, rectangular/square tubes, and open sections such as I-
beams and channels, or other structural shapes by judicious selection of the wave force
coefficients. A typical scenario is an offshore jacket structure as shown in Figure 1. The offshore
jacket can be subjected to many types of loads including wave loads and several transport ship
motions.

These structures are modeled in STAAD.Pro as shown in Figure 2. Section properties can be
assigned using the STAAD.Pro code based section database or the user can create user tables
to define custom sections. Once the section properties and supports have been assigned, the
STAAD.Pro model can be imported into STAAD.Offshore to perform the wave load generation as
shown in Figure 3.
