MODULAR PRESSURE SETS
Modular pressure sets that fit brownfield spaces and restore stable pressure fast.
Right-sized modules (pumps + bladder tank) sized for access routes and legacy tie-ins—NSF 61 wetted materials, HazLoc-ready options, and a plan to install with minimal disruption

Your Platform Can’t Afford Pressure Complaints
Brownfield realities: tight access, legacy connections, waterlogged tanks, and top-deck pressure drops.
When pressure falls off at elevation, crews lose time and trust. The modular H2O set separates pumps and bladder tank for flexible placement, fits through hatches/stairs, and ties into existing utilities—so uptime returns quickly.
- 2×100% vertical multistage pumps deliver head to upper decks—without oversizing.
- Hydropneumatic bladder tank ends waterlogging and rapid cycling.
- Potable-safe (NSF 61) wetted materials with clear re-commissioning docs.
Trusted Offshore. Proven Retrofits.
Built for offshore brownfield replacement: HazLoc-aware, potable-rated, and modular—engineered to move through narrow routes, split tank from pumps, and install cleanly in the space you’ve got.

The Cost of Doing Nothing Adds Up Fast
When watermaking equipment fails offshore, the entire operation pays the price:
-
Crew welfare dips
-
Maintenance hours spike
-
Downtime costs climb
-
Compliance risks increase
-
Morale suffers
Reliable freshwater shouldn’t be optional—it’s essential to safe, continuous offshore operations.

Frequently Asked Questions
Can you match our old tie-in points?
Every retrofit starts with a tie-in survey. We record exact nozzle size, type, orientation, and height so your replacement matches without hot work or rework.
What lead time for emergency replacements?
Standard lead times run 12–16 weeks, but in emergencies we can pre-stage modules and ship partial systems to restore water in as little as 4–6 weeks. We’ll work with your outage window to prioritize what gets installed first.
What spares should we stock?
We recommend a core kit: cartridge filters, high-pressure pump seals, membrane elements, and instrument sensors. For critical operations, we also suggest a standby high-pressure pump and full O-ring/gasket set.
Do you provide HazLoc certification?
The base system is safe-area rated. Optional upgrades are available for CSA Class/Zone Div 2 and IECEx Zone 2, with or without third-party certification depending on your project requirements.
How long does installation take offshore?
Most modular replacements are installed and producing water within a single shift once tie-in utilities are prepped. The hatchable design avoids multi-day crane operations and minimizes downtime.
Can rotating crews operate it without special training?
Yes. Controls are simplified for rotating crews. Each install includes onboard familiarization plus 24/7 access to digital training resources and videos through our 360Support portal.
What’s the expected service life?
Bluecube modules are engineered for 20+ years of offshore duty when maintained per the O&M manual. Corrosion-resistant materials and coatings are specified to meet harsh marine conditions.
