Offshore Structural Analysis and Design Software

Improve the design, analysis, safety, and reliability of offshore structures using SACS.

SACS Collapse

Offshore Collapse Analysis Software

Identify failure mechanisms from a range of dynamic events including pushover, ship impact, dropped object, and blast analysis.

Automate Offshore Structural Workflows

Customizable templates within a common structural model make it easier to manage multiple analyses. Automatically pass data from one analysis step to another using industry-standard methodologies. Automated workflows simplify the management of large and complex models, which encourage the team to explore more collapse scenarios.

Accelerate Accurate Predictions

SACS Collapse provides the ability to automate predictions with a high degree of certainty, whether analyzing nonlinear structural behavior or large deflection elasto-plastic response for platforms or piles.

Graphically Display Collapse Results

Easily visualize the outcome of full plastic analysis, including effects from impulse and time-based loading. Show failure progression, gradual plastification, and collapse mechanisms graphically.



SACS Collapse software is used to identify failure mechanisms and automate offshore structural workflows.

Zakum Development Company

“SACS software and its tailor-made enhancements is a very useful tool for structural integrity engineers where a quick workable solution is required in the shortest possible time.”


Achieve Offshore Structural Engineering Excellence

Ensure compliance with comprehensive offshore design code coverage in SACS Offshore Structure. Improve design for operational safety through ship impact and dropped object analysis, and minimize risk through offshore-specific load generation. Visualize complex structural response via an interactive graphical review of analysis and fatigue.

Featured Projects

SACS was chosen by Zakum Development Company to assess the structural integrity of a wellhead platform in Abu Dhabi.

Structural Integrity Assessment of a Ship-impacted Wellhead Platform

The USD 3 million project required Zakum Development Company (ZADCO) to evaluate and reinstate the structural integrity of an Abu Dhabi wellhead platform for resuming oil production after a ship collision. To perform the assessment and justify the resulting insurance claim, ZADCO needed to prepare a structural design brief, model pile soil interaction to determine safety of the platform and piles, and simulate the collision and post impact behavior of the structure. Given the varying hardness of the soil, uncertain vessel speed data, and an outdated model, ZADCO needed to utilize offshore modeling and analysis software to accurately assess the damage.

SACS and MOSES were used by Offshore Oil Engineering Co., Ltd. to design three jackets.

PL19-3 Oil Field Jacket Design and Development of “Fixed Offshore Structure Design Tool” Software

Located in Bohai Bay off China’s northeastern coast, the CNY 8.8 billion Bohai Development Project is a joint venture between China National Offshore Oil Corporation (CNOOC) and ConocoPhillips China Inc. The project will expand existing facilities to include two 40-slot well head platforms, a central platform, and associated pipelines and cables. As engineering, procurement, construction, and installation (EPCI) contractor, CNOOC Offshore Oil Engineering Co., Ltd. (COOEC) was charged with creating detailed designs of the offshore structures and developing engineering software.
