• The LEAPS Editor is a tool to help you view your model.

– For power users, or those with unusual requirements, the LEAPS Editor can be used to create designs beyond what ASSET is capable.

– This includes multi ‐hulls and asymmetric hulls. –

thorough knowledge of the FOCUS Data Model.• The LEAPS Database Utilities are a suite of tools for renaming,

defragmenting, and repairing your model. – It is considered a best practice to repair your model after all crashes,

and on a regular (e.g. daily) basis.• The LEAPS Toolkit is, in general, under Distribution Statement A

.

. ,

but you can contact Code 2230 for additional installs.




‐• SHCP‐L is a hydrostatics program that allows users to perform a full suite of hull

– Design Conditions – Liquid Loads

– Flooding Scenarios – – Curves of Form – Trim Lines

– Limiting Draughts – Floodable Length

– Damageable Length – Longitudinal Strength – Cross Curves – Intact Stability

ta ty – Tank Capacities• SHCLP‐L is, in general, under Distribution Statement A release as part of the LEAPS

Toolkit. You should have this tool since it is required for ASSET 6.3, but you can .




• IHDE is a computational fluid dynamics (CFD) tool for LEAPS.

• It can handle ship resistance using either a TSD or FKS

• It calculates seakeeping using either SMP (frequency

domain) or LAMPS (time domain, full viscosity).• t s sca a e an t rea sa e or g per ormance

• RSDE is currently in limited beta release. Final distribution will be throu h the CREATE Pro ram.

or an intelligent placement mode.

• The intelli ent lacement mode uses an independent ‐agent ‐based genetic algorithm to attempt to optimize the placement of compartments within the ship.

• ISA is currently (May 2012) in alpha testing.




Intelligent Ship Arrangements (ISA)

• Capabilities of ISA: – LEAPS database as input for ship

geome ry an requ remen s

– Arrangement requirements are inputas a constraints database – Passageways are laid out using an

n a a ce ne wor – ISA performs allocation and

arrangement of ship compartments – Fuzzy logic is used to lay out and
