Offshore Structural Analysis and Design Software

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

SACS Offshore Structure

Offshore Structural Analysis Software

Optimize design to ensure compliance, understand behavior, and accurately predict performance of all types of offshore structures.

Analyze Offshore Structures

Conduct comprehensive analyses – including full nonlinear, dynamic, and impact effects – to predict how your platform or topside structure will behave under a host of conditions. Model pile-soil interactions and apply wind, wave, seismic, ship impact, dropped object, and blast loads for a full range of likely effects.

Automate Your 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 encourages your team to explore more design options.

Ensure Code Compliance

Built-in checking provides assurance that your designs comply with offshore international codes, including API, AISC, EC, ISO, DNV, and Norsok. The software enables you to filter for critical conditions and provide compliance documentation.



SACS Pile Structure Design software is used to reduce the risk of failure for offshore structure foundations.

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


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.


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.
