What is MOSES?
MOSES integrated simulation software helps you minimize offshore project risks with optimal designs. This advanced hydrostatic and hydrodynamic software ensures that you can apply industry best practices to installation and design sequences, while exploring design alternatives within a unified modeling environment.
MOSES is offered in different variations so you can choose what's best for you:
Analyze stability and motions in the frequency domain cost-effectively. Enjoy hull and compartment modeling, as well as strip theory and 3D diffraction analysis.
- MOSES Advanced
Added to the benefits of the MOSES module are time domain and structural analysis capabilities.
- MOSES Enterprise
This most complete range of functions enables you to model hulls, calculate stability, predict motions, and analyze mooring, structures, and launch.
Each version of MOSES offers a package of modules that let you:
- Automate performance analysis
Easily analyze floating systems across a range of operating conditions using simulation language to define environmental conditions, specify mooring configurations, and run integrated solvers in a unified environment.
- Easily model offshore vessels and platforms Use interactive graphical tools specific to offshore structures to prepare models of your vessels and floating systems. Help ensure accurate loading definition by visualizing tank and compartment models during modification.
- Simulate marine operations
Leverage comprehensive and customizable scripting tools and pre-defined macros to explore design alternatives and manage complex installation sequences.
The modules included in all MOSES packages include:
- MOSES Solver: Allows you to consider all type of forces acting on your floating systems, including hydrostatic, hydrodynamic, inertial, and mooring forces.
- MOSES Language: Provides a unique, flexible, and powerful way of specifying system behavior and analyzing performance for different installations and operational conditions.
- Hull Modeler: Gives you an interactive way to create 3D hull shapes.
- Stability Modeler: Allows you to model compartmentation and load case management.
- Motions Modeler: Provides the tools for modeling environmental and mooring inputs.
- Hull Mesher: Enables you to graphically represent structural models.
- Basic Connectors: Offer a generalized way of modeling lifting slings, anchor lines, mooring lines, nonlinear springs, pins, fenders, and other items that connect two bodies or a body to the ground.
- Strip Theory: Provides a fast and proven way to predict the motions of your vessel.
- 3D Diffraction: Allows you to predict motions for non-ship shaped hulls and account for surge.
Additionally, MOSES Advanced and MOSES Enterprise include:
- Time Domain: Perform time-history simulations on single or multi-body systems to predict performance.
- Pipe and Rod Elements: Handle mooring line dynamics with accurate calculations or response, including accounting for large deflections.
- Structural Solver: Enable structural analysis, as well as spectral fatigue analysis of topside and cargo structures.
And MOSES Enterprise offers two additional modules:
- Jacket Launch: Perform six-degree-of-freedom time domain simulations of jacket launches from a barge into water.
- Generalized Degrees of Freedom: Understand the effect of structural deformation and flexibility on buoyancy, frequency response, and loadout calculations.
The Basic Connectors module provides a generalized way of modeling lifting slings, anchor lines, mooring lines, nonlinear springs, pins, fenders, and any other item that connects two bodies together or connects a body to the ground. Connectors can be tension-only or compression-only and custom connectors can be defined.
- Lift, lower, or upend with multiple slings and hooks
- Activate or deactivate to simulate breaking or re-rigging
- Move anchors to achieve a specified tension
- Hold hooks at elevation or load while flooding or pumping
- Catenary mooring lines with buoys or clump weights
- Nonlinear springs with tension or compression only
- Gaps, pins, and lines provide constraints to motion
Strip theory provides a fast and proven way of predicting the motions of vessels. It is well suited for barge transports and any vessel that is slender in its L/B (length/beam) ratio.
- RAOs (response amplitude operators) at CG (center of gravity) or remote locations
- Standard and user defined spectra
- Statistical multipliers or storm duration definition
Prediction of motions for non-ship shaped hulls and for situations in which surge is important. Adaptive meshing automatically increases panel mesh density as required.
- Hull Modeler automatically generates hydrodynamic meshes
- Non-linear, slowly varying, wave drift forces
The Time Domain module can perform a time history simulation on any single or multi-body system. Starting from the frequency domain results, and taking into account mooring, current, and wave forces, the Time Domain module provides fast computation of full system response. Customizable reporting and automatic generation of system response animations allow easy understanding and communication of results.
- Environment of current, irregular waves, and/or wind
- Multiple body motions can be analyzed
- Vortex shedding in wind or water is computed
- Dynamic tank flooding and emptying
Pipe & Rod Elements
When analyzing mooring line dynamics, the Pipe & Rod module allows accurate calculation of mooring line response, taking into account large deflections. This allows modelling and analysis of anchor lines, mooring lines, TLP (tension leg platform) tendons, rigid risers, and pipelines.
- Large deflection beam capability
- Handles TLP tendons, rigid risers, and pipelines
- Mooring line dynamics are included
- Combine pipe assemblies with rollers
The Structural Solver module enables structural analysis and spectral fatigue of topside or cargo structures. It supports beam and plate elements and can import structures from SACS.
- Linear, nonlinear, and frequency domain analysis
- Modal analysis using subspace iteration
- Code checking to API, AISC, NORSOK, and ISO
The Jacket Launch module can be used to perform a six-degree-of-freedom time domain simulation of a jacket launch from a barge into water.
- Automated ballasting
- Winch and friction definitions
- Optional side launch
Generalized Degrees of Freedom
The Generalized Degrees of Freedom module is used to consider the effect of structural deformation and flexibility on buoyancy, frequency response, and loadout calculations. It can also be used to consider the hydrodynamic interaction between two vessels.
MOSES imports SACS structural models for offshore installation analysis. Generating SACS TOW files from MOSES allows automatic generation of inertial based acceleration loading and RAOs.
