Small batches, specialised tasks.
The way we work rests on technical development, adaptation to the actual use and delivery of smaller or specialised batches — for seals and for underwater systems alike.
- 01Defining the taskUse, environment, quantities and constraints — together we set out what the solution has to handle.
- 02Computer-aided designConcept, material selection and preparation of the documentation.
- 03Prototype and testingA sample is built; underwater systems are tested in real sea conditions.
- 04Batch productionSmaller or specialised batches, manufactured in Slovenia.

GreenHull ROV
A robotic platform for environmentally sound underwater cleaning of ship hulls, developed under the Interreg Italy–Slovenia programme and tested in real sea conditions. Edvin Salvi is a co-author on methodology, software, validation and visualisation.
