Marine & Offshore Water Treatment Systems
From commercial fishing vessels to offshore oil platforms, reliable freshwater production at sea is mission-critical. ForeverPure engineers marine-grade watermakers and water treatment systems designed to withstand the corrosive saltwater environment while delivering consistent, high-quality potable water far from shore.
Marine Applications
- Commercial vessels — Cargo ships, tankers, fishing boats, and ferries
- Offshore platforms — Oil rigs, wind farm service vessels, and floating production units
- Naval and coast guard — Military ships, patrol boats, and support vessels
- Cruise ships and yachts — Passenger vessels requiring high-volume potable water
- Island supply vessels — Emergency water delivery to remote island communities
System Capabilities
Our marine SWRO systems are available from 500 GPD watermakers for small vessels up to 800,000 GPD systems for large offshore installations. All marine systems feature:
- 316L stainless steel and duplex stainless steel frames rated for marine environments
- Corrosion-resistant FRP membrane vessels and non-metallic piping
- Compact footprint designed for engine rooms and machinery spaces
- Energy recovery devices for fuel savings at sea
- Auto-flush and chemical-free preservation for intermittent use
- Remote monitoring via satellite for technical support while underway
Vessel-Scale Watermakers
For vessels and smaller platforms, these skid-mounted seawater RO watermakers ship ready to install. All three share the same marine-grade component set and take the same replacement membranes, so one spares kit covers a mixed fleet.
| System | Fresh water per day | Typical use |
|---|---|---|
| 200 GPD Watermaker | 200 gal (757 L) | Fishing boats, patrol craft, small crew vessels |
| 500 GPD Watermaker | 500 gal (1,893 L) | Mid-size commercial vessels, yachts, ferries |
| 1,000 GPD Watermaker | 1,000 gal (3,785 L) | Larger crews, offshore support, island supply |
Solar-hybrid versions of each capacity are built for remote stations and low-fuel operation — contact us for configuration and lead time.
Offshore Platform Solutions
Offshore platforms require water treatment systems that operate reliably in remote, harsh conditions with minimal maintenance. ForeverPure containerized desalination systems are ideal for platform deployment—they arrive fully assembled in standard ISO containers and can be crane-lifted into position. Integrated pre-treatment handles the variable water quality typical of open-ocean intake.
