About SACS SACS is an integrated suite of software

that supports the analysis, design and fabrication of offshore structures, including oil, gas, and wind farm platforms and topsides

Created by Bentley (acquired Engineering Dynamics, Inc)

Widely used in oil and gas industry Similar app: STAADPro, SESAM, SAP

In-place Analysis What is this? What for? How to do it? What we need to do it? How is the process of the analysis? What is the result? How to check the result?

Step 1: Structure Definition Let’s open SACS!

Structure Definition Can be edit / re-edit Content:

Elevation(s) Leg(s) and Batter Conductors Skirt Piles Bracing Size / Dimension Deck Girders

Assignment #1! Build jacket structure with structure definition!

NIM 155120xy x = number of leg (+- to 1,3,4,6,8) y = number of conductor |x-y| = number of riser (use reference!) Boatlanding:

If x odd number, create 1 boatlanding If x even number, create 2 boatlandings

Batter: If y odd number, use 800 batter legs If y even number, use 750 batter legs
