This document provides an overview of the SACS software, which is used for analyzing offshore structures. It discusses the history and capabilities of SACS, including that it can perform various types of analyses like pre-service, service, and incident analyses. It also outlines the process for setting up and performing an analysis in SACS, including defining the structure, running the analysis, and checking the results. The final section provides instructions for an assignment to build a jacket structure in SACS based on specific criteria.

3.  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

5.  All Analysis
 Pre-service (load out, transportation, lifting, upending)
 Service ( inplace, fatigue, seismic, pushover)
 Incident( boat impact, stability, vessel)
 Finite element analysis
 Complete standard, code, references, and theory
 GUI and result reporting
 SACS limitations? I didn’t found yet 

10.  Let’s open SACS!

11.  Can be edit / re-edit
 Content:
 Elevation(s)
 Leg(s) and Batter
 Conductors
 Skirt Piles
 Bracing
 Size / Dimension
 Deck Girders

12.  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
