Case Study Overview

This project was based on one of the Royal Navy’s Albion class amphibious assault ships. The ship lands Royal Marines and their equipment, including trucks and tanks, ashore by air and sea.

Challenge

The ship was due to undergo a major refurbishment which would include a lot of welding, cutting and grinding activities. Whilst the customer had actively put control measures in place to minimise exposure to hazardous fume and dust, and to ensure adequate air quality inside the work zones, they were struggling to achieve velocities required in accordance with HSG258, particularly for grinding dust.

The customer identified that a more specialist and high pressure extraction system was required in order to ensure the safety of everyone nearby. They reached out to RVT Group, a long-standing provider of specialist hazard control solutions across the dockyard, for a bespoke solution.

Solution

RAVEX® Wandafilta Plus Kits were installed with VENTEX® 200S HP Centrifugal fans and twin VENTEX® 300M centrifugal fans to extract dust and fume at the source.

We filtered to H14 (HEPA) standard which captures an impressive 99.99% of 0.3-micrometer air particles. This means that out of 1,000,000 particles, only 10 particles will not be captured. All of the extraction systems on site were commissioned, demonstrating that it is performing in accordance with RVT Group's design, and meeting the customer's requirements. The customer chose to have an RVT Group technician attend the site on a regular basis to check the system, and replace any filters as and when needed, to ensure that the system was performing at full capacity and productivity all times.
