HECSTAB Offshore – Regulatory Stability Assessment Software

HECSTAB Offshore is a versatile tool for the Naval Architect involved in design and regulatory analysis of non-ship shaped assets. Develop models to evaluate intact and damage stability. In addition to traditional fixed-axis free-to-trim calculations, HECSTAB Offshore can perform variable heeling axis (free twist) calculations, greatly reducing the number of calculated conditions. HECSTAB contains a fully integrated modeling package, a hierarchical analysis interface, streamlined wizard-style analysis templates, and a state-of-the-art Python scripting interface.

Used by Naval Architects, Ship Owners, Classification Societies, Military Organizations

  • Offshore vessel modeling, with Rhino3D integration

  • Intact and free-floating damage stability

  • Fixed axis (Free to Trim) evaluation

  • Variable axis (Free Twist) evaluation

  • Compatible with LMP

  • Python scripting engine

  • Flexible script-based reporting

HECSTAB Offshore is supported by the following modules:

Python Editor: Python API and script interface to extend program functionality

Python scripting interface that is fully integrated with the Herbert-ABS Application Programming Interface to run custom scripts or create new analysis templates for HECSTAB.

Ship Project Editor: Ship modeling tool

Ship and offshore modeling program to define vessel geometry and tabular information for preliminary design and regulatory assessment.

Rhino3D and Grasshopper Plugins: Rhino3D and Grasshopper integration

Plugin support to allow users to develop hull models and compartmentation in Rhino and export models for use in HECSTAB Offshore and Ship Project Editor. Use Grasshopper blocks to further extend Rhino modeling to parametrically design vessels by dynamically shifting bulkheads and automatically develop a compartmentation plan. (Rhino 7 required for plugin support, Python scripts available for older Rhino versions)

Herbert-ABS Wind: Wind overturning moment analysis from 3D geometry

Program to assess wind overturning moments for vessels directly from user-defined 3D geometry. Allows user definition of space shape factors, height coefficient tables, and thruster locations and force.

Applicability:

Offshore (non-shipshape) structures of any type, size, or operation, from semi-submersibles to TLPs, and SPARS to jack-ups.
