The IMT-Isca design series represents the next generation of platform supply vessels (PSVs), evolved from the successful IMT-984 or G-Class series, with a focus on efficiency and low-fuel consumption, whilst meeting contemporary regulations.

Its name is inspired by the Celtic word for flowing water and the River Exe – a nod to both the fortitude and flexibility of the design series, and to Longitude’s cultural heartland of Exeter.

The G-FLEX is the first PSV in the series.
