Your Project Can’t Afford Documentation Churn

EPC teams fight the same villain: redlines, missing datasheets, and non-AVL parts that stall reviews. 

Late clarifications and incomplete packages create delays, change orders, and uncomfortable client calls. Bluecube skids are engineered to clear reviews on the first pass—so milestones hold and the critical path stays green.

    • Strict specs, AVL adherence, class/HazLoc, and single-lift preferences—all accounted for up front.

    • Bid-tab clarity for Leads, clean acceptance for Package Engineers, schedule confidence for PEMs, confirmed lead times for Procurement.

    • You shouldn’t have to choose between compliance and schedule.

Trusted Offshore. Proven Worldwide.

H2O supports greenfield platforms and FPSOs with spec-compliant, single-skid watermakers engineered for EPC delivery: AVL-aligned components, distributed inspections, module-level FAI, and FAT that feels routine—not heroic.

Our track record is simple: First-pass submittals. Lift-ready installs. On-time turnover.

The Cost of Doing Nothing Adds Up Fast

When suppliers bring exceptions or thin submittals, schedules slip and costs climb:

  • Redlines and rework cycles

  • Late certifications and missed milestones

  • Field modifications and commissioning surprises

Choose a package engineered for first-time approval and predictable delivery.

  • Utilities: 208–480V 3ph/50 or 60Hz

Options & Upgrades

INLET & PRETREATMENT

BlueCube inlet configurations ensure stable RO feed conditions even when platform seawater pressure is inconsistent. A boost pump is available in either 1x100% or 2x100% duty to support low-pressure sources such as seachests. A pressure control valve can also be added to regulate variable feed pressures and maintain a consistent inlet supply to the RO system.

CHLORINE REMOVAL OPTIONS

For locations with chlorinated seawater supply BlueCube systems remove chlorine using one of two methods. A carbon contactor provides physical adsorption, or chemical injection (SBS) neutralizes free chlorine through chemical reduction.

PREFILTRATION UPGRADES

For locations with higher suspended solids or seasonal turbidity, BlueCube offers enhanced pretreatment. A basic media filter improves upstream solids removal, an automated media filter adds automatic backwash functionality, and a bag filter provides a compact, serviceable option for moderate TSS levels.

CONTROLS AND INSTRUMENTATION

BlueCube systems can be tailored to the platform’s automation needs. Basic controls provide essential instrumentation and protection logic, while advanced controls add an HMI, transmitters, and DCS integration. Both options are available in safe area or HazLoc configurations.
PRESSURE SAFETY OPTIONS
Pressure protection can be supplied to different standards. The basic pressure safety package includes relief valves and vacuum breakers across key lines, while the API pressure safety package provides upgraded components for facilities requiring API-level compliance.

POTABLE WATER OPTIONS
To meet potable water requirements, BlueCube offers multiple post-treatment configurations. The basic potable water package includes pH neutralization, corrosion control and disinfection, while the advanced potable water package adds enhanced monitoring and record keeping.

MEMBRANE CLEANING
BlueCube supports long-term RO performance with two cleaning configurations. A manual CIP system enables operator-performed membrane cleaning, while a fully automated CIP system cleans without manual intervention.

Frequently Asked Questions

What makes your submission “bid-tab ready”?
A compliance matrix, organized technical data, and preliminary layout in your evaluation format.

 

Can you meet our AVL and certification stack?
Yes—AVL-approved components with class/HazLoc evidence embedded in the SDRL.

 

How do you protect our schedule?
RapidFlow™ parallel fabrication, module-level FAI, and distributed inspections de-risk FAT and compress the timeline.
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.
