The latest version of classification society Germanischer Lloyd's (GL) thickness measurement software Pegasus, was recently released. To verify the structural integrity of a vessel, hull thickness measurements must be periodically take, with each measurement point documented. The number of required measurement points can number up to 20,000 - all repeatedly measured over the life of the vessel, creating a vast amount of essential data which must be effectively managed and assessed.
GL developed Pegasus to improve the preparation, recording, assessment, storage and reporting of such measurements, this latest release of Pegasus extends the current hull integrity management package to include combined functionality with the condition monitoring package GL HullManager. 3D models utilised in GL HullManager can be used directly for recording thickness measurements with Pegasus, while thickness measurements recorded with Pegasus can be easily integrated and used in GL HullManager. The accumulation of an accurate long-term database of thickness measurement results allows more precise scheduling and planning for repairs, as well as predicting future corrosion.
Release 2.0 of Pegasus offers an integrated software solution supporting thickness measurements independent of whether or not a 3D structural model is available. Even partially incomplete 3D structural models are supported by using tabular input for the missing parts. Independent of which method is used for recording assessments like hot spot lists and statistics, as well as reports in IACS format are presented in a unified manner.
New features in version 2.0 include: integration of 3D model based and table based recording of measurements and assessment functionality, a revised navigation panel which gives a better overview of the measurement content and program functionality and support for table based measurement recording and assessment for bulkers and tankers built according to IACS Common Structural Rules.
First released in 2008, GL Pegasus was introduced for recording thickness measurements to 3D structural models. Two years later, GL Pegasus Lite became a mandatory tool for all GL certified thickness measurement companies. It was able to handle thickness measurements without requiring a 3D structural model of the vessel. Currently more than 300 GL certified thickness measurement companies use GL Pegasus Lite. GL Pegasus and GL Pegasus Lite will now be replaced by the integrated version Pegasus 2.0.
Pegasus 2.0, like GL Pegasus Lite, is available free of charge. Program licenses required for using a structural 3D model are available on request.
