Differences between MOSES and MAXSURF

Area:Product information




Type of design

Used for:

  • Workboats
  • Barges
  • Floating cranes

Used for ships and boats:

  • Workboats
  • Fast Ferries
  • Patrol
  • Defense
  • Offshore supply vessels
  • Yachts
  • Ships 
  • Catamarans



Graphical Modeling Interface in MOSES are the MAXSURF technology.


Analysis types

More advanced analysis:

  • Transportation
  • Launch
  • Upend
  • Lift
  • Floating Wind Turbine
  • Floatover
  • Floaters
  • Pipelining
  • Mooring
  • Global Performance

Includes most MAXSURF ship design features.

Simpler analysis, focused on ship design:

  • Hull modeling
  • Strength
  • Seakeeping
  • Stability
  • Weight and Balance
  • Initial Structure
  • Resistance
  • Hydrostatics

Multi/Single body analysis

Multi-body analysis i.e. Ship and floating dock.

Single body analysis.


Intact and damage.

Transverse and Longitudinal stability. 

Intact, damage and probabilistic damage.

Stability calculated in transverse direction.


More advanced analysis. For example in Panel method, MOSES can have a different damping matrix for each encounter frequency.

Simpler analysis. For example, in Panel method, the user can only specify one damping matrix that is applied to all frequencies.


Structural analysis as well as spectral fatigue analysis of topsite and cargo structures.

Import structures from SACS.

Dedicated SACS technology for code checking.

Multiframe - simple tool suited to sectional models.

Additional features

More advanced analysis.

MAXSURF Resistance



Overlaps: They share components for creating models and stability layouts that are nearly the same. Any hull form that you can create in MAXSURF, you could also create in MOSES.

Example of how MOSES, MAXSURF and SACS can work together:

While this scenario, a crane barge lifting a module on to a turret-moored FPSO, might not be a common offshore operation, it does highlight the interoperability between SACS, MOSES, and MAXSURF. Each body/part in this simulation can be described as follows:​

All of these parts have been joined together using MOSES connectors (slings, bottom catenaries, fenders etc) and then the operation has been simulated with the MOSES Executive.
