Subsea blasting

This innovative blasting solution offers a significantly safer, quieter and more efficient approach than traditional high-pressure water systems, without the need for retro jets. With very low blasting pressures, the SubSeaSeries is the most cost-effective solution for removing marine growth, paint and rust. Perfect as pre-treatment for inspection but also for an SA 2½ finish.

Subsea blasting

The blast chain

In the world of underwater blasting, higher blasting pressure is necessary because of the back pressure of the water around the nozzle. Thereby, additional safety features on the machine are essential to ensure a safe working environment for divers.

Choosing the right abrasive and grain size are important factors for efficient underwater blasting.

To achieve the highest possible production rate, large nozzles are used, which also requires the compressor to have a large capacity. As with all blasting operations, it is essential that the compressed air is then dry and clean to avoid blockages and machine problems.
