CrownLINER Cure In Place Piping
Trenchless Pipe Rehabilitation for Marine & Industrial Systems

Trenchless Pipe Rehabilitation for Marine & Industrial Systems
CrownLINER is an advanced Cure-In-Place Piping (CIPP) solution designed to rehabilitate aging or damaged piping systems without the need for costly and disruptive replacements. This trenchless technology allows for internal pipe restoration using a flexible saturated liner that cures in place to create a seamless, jointless, and corrosion-resistant new pipe within the original infrastructure.
Engineered for marine vessels, offshore platforms, and industrial facilities, CrownLINER offers a durable, fast, and environmentally conscious alternative to full pipe replacement—minimizing downtime and maximizing operational life.
Why Choose CrownLiner CIPP?
CrownLiner is installed entirely from within the existing pipeline, meaning there’s no need to cut walls, floors, or structures.
Once cured, CrownLiner forms a new load-bearing pipe with excellent resistance to pressure, corrosion, and mechanical stress—significantly extending the lifespan of the system.
Specially formulated for environments exposed to seawater, chemicals, oils, and gray/black water, CrownLiner maintains performance in high-moisture, corrosive, and high-traffic service conditions.
With fast installation and curing cycles, most rehabilitation projects can be completed in hours—not days—avoiding costly system shutdowns and maintaining service continuity.
Reduces material waste, avoids demolition, and eliminates the need to dispose of old pipe infrastructure—lowering environmental impact.
Recommended Applications
Crowned Marine
CrownLINER CIPP is ideal for a wide range of onboard and industrial pipe systems:
Potable Water Lines
Gray & Black Water Systems
Drainage & Ventilation Pipes
Chemical Waste Lines
Marine Sanitary Systems & Engine Room Piping
Industrial Underground Infrastructure
All systems are custom-engineered for marine applications, from cruise ships and ferries to offshore platforms and commercial fleets.
Integrated Piping System Rehabilitation Services
At Crowned Marine, we offer a specialized suite of services designed to maintain, repair, and optimize critical piping systems across marine and industrial environments. Whether your pipelines are suffering from corrosion, reduced flow, leaks, or aging materials, our integrated approach ensures minimal disruption and maximum performance.
Restoring Flow & Removing Contaminants
Our pipe cleaning service ensures internal piping systems are free from scale, corrosion, biological buildup, and debris. Using specialized tools, chemical flushing, and high-pressure systems, we restore flow capacity and prepare pipelines for lining or continued operation.
Structural Rehabilitation with Minimal Disruption
Our pipe lining solution applies a durable, corrosion-resistant liner inside the existing pipe creating a seamless “pipe within a pipe” without the need for demolition. Ideal for marine, offshore, and industrial facilities, our liners restore structural integrity, stop leaks, and protect against future damage.
Safe Extraction of Failed or Obsolete Bladder Liners
Existing bladder liners degrade or fail, we offer a specialized removal service that safely and efficiently. Whether installed in potable water tanks, black/gray water systems, or pressurized applications, our technicians use non-invasive methods to eliminate old liners and prepare the system for re-lining.
Inspection, Installation & Support
Every CrownLiner installation begins with a detailed internal pipe inspection using high-resolution cameras to assess system condition. Our certified technicians then prepare the pipe, install and cure the liner, and perform final post-lining quality testing.
We offer:
In-vessel pipe rehabilitation for cruise ships and naval fleets
Industrial retrofit projects with limited access
Scheduled maintenance integration and pipe lifespan extension
Documentation and compliance support (USPH, DNV, ISO)
