Bentley SACS

Description

SACS Offshore Structure Suite — Integrated Overview

1. Core Purpose

• SACS is a package of integrated finite element structural analysis applications for designing, analyzing, and ensuring the safety/reliability of offshore structures — oil & gas platforms, wind farms, and FPSO/floating platform topsides.
• Used globally by offshore engineers to predict structural behavior, automate workflows, and ensure compliance with international design codes.

SACS Offshore Structure

• Conducts full non-linear, dynamic, and impact analyses.
• Models pile-soil interactions.
• Applies wind, wave, seismic, ship impact, dropped object, and blast loads to predict platform/topside behavior under multiple conditions.

SACS Fatigue Ultimate

• Analyzes cyclic stress effects to minimize risk of failure from cyclic loading.
• Offers wind, wave, spectral, time history, and deterministic fatigue analysis.
• Performs fatigue damage assessments for both new and existing designs.
• Includes spectral wind fatigue calculations (with gust effects and spatial correlation) and wave-action damage assessment over time.
• Enables interactive redesign of tubular joints to optimize fatigue life, factoring in time-history analysis.
• Simulates dynamic environments (random wave, seismic base-driven response) using time history integration and design code response spectra.

SACS Collapse

• Determines structural operating limits and identifies failure mechanisms: pushover, ship impact, dropped object, and blast events.
• Uses non-linear finite element analysis to reduce risk of failure from extreme environmental or accidental loads.
• Supports full plastic analysis for initial design, recertification, and safety case work.
• Graphically visualizes failure progression, plasticization, and collapse mechanisms.
• Fully integrated with SACS Offshore Structure (no re-modeling needed) and can couple with Dynamic Response module for improved accuracy.

SACS Pile Structure Design

• Performs nonlinear analysis of soil-pile-structure interaction to reduce fatigue risk in foundations.
• Assesses soil capacity under operating and extreme loads (axial, lateral, torsional) using nonlinear load-deflection curves.
• Accounts for reduced soil capacity due to liquefaction in seismic zones.
• Fully integrated with SACS Offshore Structure for streamlined, code-compliant design.

 SACS Wind Turbine

• Extends SACS Offshore Structure capabilities (combined with third-party aeroelastic solvers) to fixed-foundation offshore wind turbines.
• Subjects wind turbine foundations to wave, wind, and mechanical loading.
• Predicts both fatigue life and extreme loads for substructures and nonlinear foundations.

7. Cross-Module Common Themes

• Workflow Automation: All modules use customizable templates within a common structural model, automatically passing data between analysis steps to simplify management of large/complex models and encourage exploration of more design options.
• Code Compliance: Built-in checks ensure designs comply with major international codes — API, AISC, EC, ISO, DNV, and Norsok — with filtering for critical conditions and compliance documentation.
• Integration: All modules work within a single, fully integrated environment, ensuring data integrity and eliminating duplicate modeling effort.
