iVP Modularity


The Fathom Systems iVP is a 3000msw (optional to 6000msw) depth rated subsea unit featuring mechanical modules manufactured from Aluminium grade 6082T6, hard anodised to BS5599, dyed-black & dichromate sealed.

The iVP uses industry standard Wandfluh fully proportional electro-hydraulic spool valves, Hydraforce proportional pressure control valves and SUN Hydraulics pressure relief/safety valves.  The system is supplied with dedicated topside branded PC and control software.  Examples of bespoke applications successfully undertaken can be viewed in the main iVP section.

Due to its modular design, we are able to offer the client almost endless options in terms of configuration depending on their requirements.  This allows a system to be specified and built to meet the exact needs of the client’s hydraulic and operational requirements and in turn saves money by not having to commit to a larger system where a number of functions may never be used.
