High-Pressure Water Blasting & Defouling

Professional Marine Cleaning & Surface Preparation Services

Wells Marine provides specialist high-pressure water blasting and marine defouling services for vessels, marine infrastructure and waterfront assets throughout Sydney, the east coast and inland New South Wales.

Marine growth, barnacles, algae, mussels and accumulated debris can significantly affect the performance, safety and lifespan of marine assets. Left untreated, marine fouling accelerates corrosion, increases vessel drag, restricts water flow and makes inspections or maintenance more difficult.

Using commercial-grade high-pressure water blasting equipment and experienced commercial divers, Wells Marine safely removes marine growth while protecting the integrity of the underlying structure.

Contact Wells Marine to arrange professional underwater cleaning and defouling services.

Complete Marine Defouling Services

Marine fouling begins almost immediately after a structure is submerged. Over time, layers of algae, barnacles, oysters, mussels and other marine organisms can attach themselves to underwater surfaces.

Our defouling services include:

• Vessel hull cleaning
• Pontoon cleaning
• Wharf cleaning
• Jetty cleaning
• Marina maintenance
• Pile cleaning
• Boat ramp cleaning
• Slipway cleaning
• Intake structure cleaning
• Underwater infrastructure cleaning
• Marine growth removal
• Surface preparation before inspections
• Cleaning prior to underwater repairs
• Biofouling removal
• Preventative maintenance cleaning

Every project is tailored to the structure, coating system and environmental conditions.

High-Pressure Water Blasting

Safe and Effective Surface Cleaning

High-pressure water blasting removes stubborn marine growth, sediment, corrosion products and contaminants without the use of harsh chemicals.

This process restores clean surfaces while preparing marine assets for:

• Structural inspections
• Protective coatings
• Underwater welding
• Concrete repairs
• Cathodic protection
• Marine construction
• Maintenance works
• Asset condition assessments

Our operators carefully adjust water pressure to suit the asset being cleaned, preventing unnecessary damage to coatings or structural materials.

Vessel Hull Cleaning

Improve Vessel Performance

Marine growth on a vessel’s hull increases drag through the water, reducing fuel efficiency and overall performance.

Wells Marine provides underwater hull cleaning for:

• Commercial vessels
• Ferries
• Workboats
• Barges
• Tug boats
• Fishing vessels
• Government vessels
• Recreational boats

Routine hull cleaning helps maintain vessel performance while reducing fuel consumption and operating costs.

Wharf and Jetty Cleaning

Maintaining Marine Infrastructure

Wharves and jetties are continually exposed to marine growth that can accelerate deterioration and make inspections difficult.

Our commercial divers clean:

• Wharf piles
• Structural beams
• Fender systems
• Deck supports
• Bracing
• Steel components
• Concrete structures
• Timber elements

Removing marine growth allows engineers and asset managers to properly inspect underwater structures and identify maintenance requirements.

Pontoon and Marina Defouling

Protecting Marina Assets

Floating pontoons, marina piles and berthing infrastructure require regular cleaning to maintain their appearance, functionality and structural condition.

Our services include:

• Pontoon cleaning
• Finger pontoon cleaning
• Berth maintenance
• Pile cleaning
• Walkway cleaning
• Gangway cleaning
• Marina infrastructure cleaning

Regular maintenance improves safety for marina users while helping extend the life of marine infrastructure.

Surface Preparation for Marine Repairs

Preparing Structures for Maintenance

Successful underwater repairs begin with clean, properly prepared surfaces.

High-pressure water blasting removes marine growth and contaminants before:

• Underwater welding
• Thermal cutting
• Concrete repairs
• Cathodic protection installation
• Protective coating application
• Structural inspections
• Engineering assessments

Proper preparation improves the quality and longevity of repair work.

Intake Structure Cleaning

Maintaining Water Flow

Marine growth can restrict water flow through intake systems used by industrial facilities, utilities and marine infrastructure.

Wells Marine removes fouling from:

• Intake screens
• Pipes
• Culverts
• Cooling water systems
• Pump stations
• Water infrastructure

Regular cleaning helps maintain efficient system performance and reduces the risk of blockages.

Commercial Diving Support

Underwater Cleaning Specialists

Our experienced commercial divers safely perform underwater cleaning in a wide variety of marine environments.

Projects commonly include:

• Ports
• Harbours
• Marinas
• Bridges
• Seawalls
• Slipways
• Boat ramps
• Industrial facilities
• Water treatment plants
• Marine terminals

Working below the surface allows cleaning to be completed without removing many assets from service.

Preventative Maintenance Programs

Reduce Long-Term Maintenance Costs

Routine cleaning forms an important part of any marine asset maintenance program.

Benefits include:

• Early identification of defects
• Reduced corrosion risk
• Improved structural inspections
• Extended asset life
• Lower maintenance costs
• Improved operational performance
• Better presentation of marine assets

Scheduled cleaning can significantly reduce the need for major repair work over time.

Environmentally Responsible Cleaning

Protecting Marine Ecosystems

Marine cleaning activities require careful planning to minimise environmental impacts.

Wells Marine follows best-practice procedures by:

• Selecting appropriate cleaning methods
• Managing marine debris
• Protecting surrounding infrastructure
• Working within environmental approvals
• Minimising disturbance to surrounding waterways
• Using water blasting instead of chemical cleaning where appropriate

Each project is planned to suit local environmental conditions and regulatory requirements.

Our Water Blasting & Defouling Process

Initial Assessment

We inspect the structure, identify the extent of marine growth and determine the most suitable cleaning methodology.

Project Planning

Our team develops a work plan considering:

• Water depth
• Access
• Marine growth type
• Asset condition
• Environmental requirements
• Safety controls

Cleaning Operations

Commercial divers carry out high-pressure water blasting using equipment suited to the asset being cleaned and the surrounding environment.

Inspection

Once cleaning is complete, the structure is inspected for damage, corrosion, cracking or other defects that may have been hidden beneath marine growth.

Reporting

Where required, we provide underwater photographs, video footage and condition reports to support future maintenance planning.
