MOSES

MOSES

Analyze stability and motions in the frequency domain cost-effectively with MOSES. Enjoy hull and compartment modeling, as well as strip theory and 3D diffraction analysis.

The modules included in all MOSES packages include:

• MOSES Solver: Consider all type of forces acting on your floating systems, including hydrostatic, hydrodynamic, inertial, and mooring forces.
• MOSES Language: Specify behavior and analyzing performance for different installations and operational conditions.
• Hull Modeler: Create 3D hull shapes.
• Stability Modeler: Model compartmentation and load case management.
• Motions Modeler: Tools for modeling environmental and mooring inputs.
• Hull Mesher: Graphically represent structural models.
• Basic Connectors: Model lifting slings, anchor lines, mooring lines, nonlinear springs, pins, fenders, and other items that connect two bodies or 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: Predict the motions of your vessel. 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
• 3D Diffraction: Predict motions for non-ship shaped hulls and account for surge. Adaptive meshing automatically increases panel mesh density as required.
  • Hull Modeler automatically generates hydrodynamic meshes
  • Non-linear, slowly varying, wave drift forces

MOSES Advanced

MOSES Advanced builds on the benefits of MOSES and includes time domain and structural analysis capabilities.

In addition to what is included in MOSES, MOSES Advanced and MOSES Enterprise include:

• Time Domain: Perform time-history simulations on single or multi-body systems to predict performance.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 and Rod Elements: Handle mooring line dynamics with accurate calculations or response, including accounting for 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
• Structural Solver: Enable structural analysis, as well as spectral fatigue analysis of topside and 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

MOSES Enterprise

MOSES Enterprise offers the most complete range of functions and enables you to model hulls, calculate stability, predict motions, and analyze mooring, structures, and launch.

MOSES Enterprise offers everything that is in MOSES Advanced as well as two additional modules:

• Jacket Launch: Perform six-degree-of-freedom time domain simulations of jacket launches from a barge into water.
  • Automated ballasting
  • Winch and friction definitions
  • Optional side launch
• Generalized Degrees of Freedom: Understand 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.
