When water systems stall, operations stall

We know the pressure of keeping water flowing and inspections clean while the clock is ticking.
Tight Spaces and Tough Installs
When machinery spaces and hatches are too small for standard systems, installation becomes a fight against space. H2O solves this with modular and skidded packages that pass through tight access points or lift in ready to run no rework or cutting required.

Meeting the Certifications You Need
Every project faces different flag, class, or hazardous-area requirements and missing one is not an option. H2O systems come ready with the approvals you need: BOSS and Crapzapper units carry USCG and IMO certifications, BlueCube watermakers hold ABS approval, and optional ABS, DNV, BV, IECEx, or Class I Div 1/2 certification ensures acceptance anywhere you operate.

Confusing Controls and Crew Turnover

Parts Headaches and Delayed Service

Slow Builds and Surprise Delays
Traditional fabrication waits for the entire skid before testing, so problems appear when time is tight.H2O’s RapidFlow process runs engineering, fabrication, and testing in parallel for each module, exposing issues early and shortening delivery.
How RapidFlow Works
Scope Creep and Communication Gaps
Custom projects often drift when requirements are unclear or keep changing.H2O assigns a dedicated project manager from kickoff to shipment and uses our online product configurator tools to capture every requirement upfront so nothing gets missed and every spec stays aligned through delivery.
