TNA Onboard Stability Program

This program was written in house in the programming language Borland C++, in 1998, and has been further developed over the years on an ongoing basis, and lately significantly updated using Embarcadero C++ 10.1 Berlin, to include a completely new reporting system, and to accommodate the calculation for Stability Effects of a Drill String contacting the side of a Moonpool, applicable to drillships. (A calculation method approved by Lloyds and ABS).

The latest version name being Baraccuda Ver 2017f2.

The new reporting system also has features for zooming and scrolling the entire report on screen before electing to either print it, or export it to directly to PDF.

The program is extensively used inhouse in the preparation of stability books, with some 1000+ Stability Books having produced using this software, for approval by various Classification Societies and Flag States. However it is also currently installed on more than 32 operational ships, including all of the Debeers Diamond Mining Ships, most of the Dept of Environmental Affairs Research Ships, many of the South African based Smit Tugs and Supply Vessels, plus other individually owned vessels.

The program supports multiple stability criteria including Wind and Waves, Supply Vessel, Multihull, Passenger Crowding, Towing Stability, Icing, Crane Stability, and limited "added-weight" damage stability, with recent update for Australian Livestock Criteria, and can use MAXVCG data for compliance reference.

The program as from 2006, also includes Longitudinal Strengths Capabilities.
