Damage Stability Compliance with NAPA Loading Computer

MEPC has strengthened the rules for tankers regarding damage stability. All tankers must be fitted with a stability instrument capable of verifying compliance with intact and damage stability requirements.

NAPA has a solution for you. NAPA Loading Computer software has been a forerunner in this field by offering direct damange stability calculation since 1993. NAPA systems for loading calculations, stability analysis, damages control and performance calculations are based on the same 3D vessel model and software that is used for designing the vessel.

NAPA Loading Computer and Damange Stability system have been generally approved by a number of authorities and classification societies, among them Lloyd's Register and DNV-GL.

With NAPA you can always calculate with the latest rules. We can offer an update to an existing NAPA Loading Computer software or prepare a new software to comply with the new regulations.

Let us help you. For more information, please contact: obnapa.service@napa.fi or sales@napa.fi

Steel1 Light

NAPA Designer is an interactive state of the art geometry modelling tool for Naval Architecture and NAPA’s 3D structure design application NAPA Steel. It brings a completely new way of making real interactive ship design from concept level naval architecture up to structural plan approval and engineering. NAPA Designer offers an intuitive 3D modelling interface, requiring little training for a vessel designer to adapt to from a conventional 2D approach.

NAPA Designer was developed in close co-operation and valuable input from over 200 NAPA customers in 22 countries. Tekes, the Finnish Funding Agency for Innovation, and Idean, a global design firm specializing in superior User eXperiences played an important role in research and development work. Combining extensive, systematic R&D with NAPA’s 25 years’ experience in ship design software development we can now deliver a best-in-class solution, allowing design teams to meet the challenges of the future with confidence. NAPA Designer will deliver a significantly improved design platform for new and existing NAPA users alike and allow them to meet ship modelling requirements without additional time investment.

Examples of powerful NAPA Designer usage:

NAPA Designer for Structure Design: NAPA Designer & NAPA Steel & interface_to_rules for CSR BC&OT.
Together with the NAPA’s structure design application NAPA Steel and the extensive collection of class society rule interfaces it forms an effective packages for plan approval of many special ships and especially for CSR BC&OT ships. Read more in press release.

NAPA Designer for Statutory Compliance: NAPA Designer & NAPA Statutory Compliance manager.
The power of NAPA Designer can be used effectively together with Statutory Compliance manager for producing statutory calculations and high quality, comprehensive reports like Loading Manual and Stability Booklet. Read more in press release.
