NAPA Offshore

Designing offshore structures poses specific and serious challenges for naval architects. NAPA for Offshore tools include dedicated analysis and modelling applications that enable time-efficient and optimized designs. NAPA is the preferred choice by the leading offshore design consultancies, classification societies, and builders worldwide.

NAPA Offshore enables efficient design of offshore structures, such as jack-ups



3D structural design for even the most complicated geometries

  • Modelling capability allowing the handling of any geometry flexibly and efficiently
  • Unique hull model enabling conceptual design, stability analysis and structural modelling
  • Comprehensive offshore structure stability analysis function for
  • Following the stability analysis process
  • Defining loading conditions
  • Wind moments
  • Damage cases
  • Criteria checking
  • Calculating limiting VCG values
  • Watertight and weathertight diagrams in 3D and to DXF
  • Generating  required documentation
  • Hydrodynamic analysis for short and long term approach of the platform and ships’ motions
  • Capability for calculating and export wave loads for global structural analysis
  • Ability to assess seakeeping criteria as defined by the user (e.g. using ISO or NATO standards), enabling a clear understanding of performance restrictions and estimated total downtime
  • Export to production design systems enables smooth transition and increased efficiency
