MOSES

Basic Connectors
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
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

3D Diffraction
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

Time Domain
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

Structural Solver
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

Jacket Launch
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-SACS Interoperability
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.
