Download MOSES 25.0 – Offshore Engineering Simulation Software

MOSES 25.0, developed by Bentley Systems, is a specialized simulation program designed for the marine and offshore engineering industries. It provides high-fidelity analysis for lifecycle marine operations, including offshore structure design, heavy-lift vessel operations, and floating system analysis, integrating hydrostatics, hydrodynamics, structural mechanics, and soil mechanics.

Overview of MOSES in Offshore and Marine Engineering

MOSES serves as a critical tool for marine and offshore engineers, facilitating the simulation and analysis of complex operations throughout the lifecycle of offshore structures. Its comprehensive approach supports the transportation, launch, upending, and installation of components such as offshore jackets, topsides, and wind turbine foundations. The software is particularly vital for projects requiring detailed modeling of marine operations and heavy lifting scenarios, ensuring safety and efficiency according to industry standards.

Comprehensive Simulation Modules for Marine Operations

Hydrostatics and Vessel Stability Analysis

This module enables engineers to perform detailed intact and damage stability computations for marine vessels and offshore structures. It supports calculations necessary for regulatory compliance with international codes, including those set by the International Maritime Organization (IMO) and the U.S. Coast Guard (USCG). Engineers can accurately predict parameters such as righting arms, GZ curves, and downflooding angles.

Hydrodynamics and Motion Calculations

MOSES provides capabilities for both frequency- and time-domain analysis of vessel motions in various sea states. It facilitates the prediction of Response Amplitude Operators (RAOs), calculation of wave loads, and detailed analysis of mooring system behavior under operational conditions. This ensures that floating structures and vessels maintain stability and manageability in dynamic marine environments.

Marine Operations and Heavy-Lift Simulation Capabilities

The software offers specialized tools for simulating complex marine operations. This includes detailed modeling of launch and upending sequences for jackets and other large structures, as well as dynamic analysis of heavy-lift operations. Transportation analysis for marine structures is also a key capability, allowing engineers to plan and verify the safe transit of components at sea.

Structural and Soil-Structure Interaction Models

MOSES integrates a Finite Element Method (FEM) solver for comprehensive structural strength analysis of offshore components. Complementing this, its soil mechanics module allows for the modeling of soil-structure interactions, crucial for the design and installation analysis of offshore foundations and pile-driving operations. This combined approach provides a holistic view of structural integrity.

Efficiency and Workflow Optimization in MOSES 25.0

MOSES 25.0 is engineered to streamline complex engineering workflows. The software supports multi-stage operational modeling, allowing for the simulation of sequential events in marine operations. Its scripting and batch automation capabilities enable users to efficiently manage complex, repetitive analyses and custom workflows. Advanced 3D visualization tools aid in understanding simulation results and communicating design insights.

Recent Enhancements in MOSES 25.0

The latest release, MOSES 25.0, introduces significant advancements. A key feature is the modernization of the graphical user interface through MOSES Ultimate, enhancing user experience. Computational performance has been improved with faster solvers, leading to more efficient analysis. Furthermore, integration enhancements with Bentley’s broader offshore product suite, including SACS for structural analysis and OpenWindPower for wind energy applications, create a more cohesive and powerful environment for offshore engineering projects.

Industrial Applications and Case Examples

MOSES is indispensable in numerous real-world applications within the marine and offshore sectors. Critical use cases include the complex installation of offshore wind turbine foundations, the safe launching and positioning of large offshore jackets, and the operational planning and analysis for heavy-lift vessel operations. The software’s ability to model intricate multi-stage events makes it essential for detailed engineering design and risk assessment.
