MOSES 25.0

MOSES 25.0

MOSES (Master of Offshore and Ship Engineering Systems) is a premier, high-fidelity engineering analysis program for the marine and offshore industries. Developed by Bentley Systems, it is used for the simulation and analysis of complex marine operations such as the transportation, launch, upending, and installation of offshore structures (jackets, topsides, wind turbine foundations), heavy-lift vessel operations, mooring analysis, and floating system design. It integrates hydrostatics, hydrodynamics, structural mechanics, and soil mechanics in a single environment to assess the behavior of structures in the marine environment under various stages of their lifecycle.

It is an essential, industry-respected tool for ensuring the safety, feasibility, and optimization of high-risk, high-cost offshore projects.

Key Features & Capabilities

MOSES is a comprehensive simulation suite built for the specific challenges of offshore engineering.

Core Analysis Modules:

1. Hydrostatics & Stability:

   • Intact & Damage Stability: Full compliance with regulatory codes (IMO, MODU, USCG). Calculates righting arms, GZ curves, and downflooding angles.

   • Loadout & Weight Management: Tracks center of gravity (CG) and weight changes throughout all stages of a marine operation.

2. Hydrodynamics & Motion Analysis:

   • Frequency & Time-Domain Analysis: Predicts vessel and structure motions (RAOs), wave loads, and accelerations in regular and irregular seas using panel diffraction/radiation methods (potential flow).

   • Mooring Analysis: Static and dynamic analysis of spread mooring systems, turrets, and single-point moorings.

3. Marine Operations & Heavy-Lift Simulation:

   • Launch & Upending Simulation: Models the controlled launch of jackets from barges and their subsequent upending to a vertical position.

   • Lift Analysis: Simulates lifts using floating crane vessels, accounting for vessel motions, hook loads, sling dynamics, and tagline forces.

   • Transportation Analysis: Assesses barge and cargo seafastening design for ocean tows, calculating loads and motions during transit.

4. Structural & Geotechnical Interface:

   • Integrated FEM Solver: Includes a finite element solver for analyzing local and global structural strength during operations (e.g., lifting padeyes, grillage, jacket legs).

   • Soil-Structure Interaction: Models pile driving and foundation behavior for installation.

Key Workflow Advantages:

• Multi-Stage Analysis: Define a sequence of operational stages (float-off, tow, upend, piling) in a single model to assess the entire installation process.

• Scripting & Automation: Powerful command-line (ASCII input) and GUI interface, allowing for parameterization, batch runs, and custom automation.

• Advanced Visualization: 3D graphical post-processor for viewing deformations, stresses, and animated motion sequences.

What’s New in Version:

• Modernized User Interface (MOSES Ultimate): Bentley has been developing a new graphical user interface (GUI) to complement the traditional command-driven interface.

• Performance Enhancements: Faster solvers and improved computational efficiency.

• Enhanced Integration: Tighter links with other Bentley offshore products like SACS (structural analysis) and OpenWindPower.

• Updated Standards & Methods: Incorporation of latest industry guidelines and best practices.
