Superseded generic equivalent solutions for the national standard

As the national standard is updated, generic equivalent standards (GES) are being superseded.

The national standard for commercial vessels is being progressively introduced to replace the Uniform Shipping Laws Code (USL Code). As technology changes and improves, other solutions are available for meeting the standard. These are known as generic equivalent solutions (GES). They are available to address situations that may be outside the original scope of the standard, but will achieve the necessary outcomes to be compliant.

GES provide alternative ways to meet the national standard for commercial vessels. GES are made to facilitate innovation, modernisiation and emerging technologies. You can apply a GES to your vessel during design or construction or once the vessel is operating. 

As the national standard progresses, the GES will be updated. There are a number of GES which have been superseded. These superseded GES are provided for your information only. To view the current versions please visit the equivalent solutions for the national standard.
