Restore the Safety, Performance & Compliance of Your Lifeboats and Launching Systems
Lifeboats and their launching appliances are among the most critical life-saving systems onboard any vessel. Continuous exposure to harsh marine environments, impact damage, heavy operational loads, and corrosion can affect the structural integrity of Fiberglass Reinforced Plastic (FRP) lifeboats and the performance of davit winch systems.
Timely FRP Lifeboat Repairs and Davit Winch System Overhaul are essential to restore equipment to its original operating condition, extend its service life, and ensure compliance with IMO, SOLAS, LSA Code, MSC.402(96), manufacturer recommendations, and applicable Class requirements.
Whether the repairs are carried out onboard or at an approved workshop, professional servicing ensures your lifesaving equipment remains safe, reliable, and ready for emergency use.
Why FRP Lifeboat Repairs Are Important
Modern lifeboats are manufactured using Fiberglass Reinforced Plastic (FRP) due to its exceptional strength, lightweight construction, corrosion resistance, and long service life. However, prolonged exposure to harsh marine conditions, accidental impacts, grounding, UV radiation, and normal wear can result in structural damage.
Professional FRP repairs help to:
- Restore structural strength
- Prevent further deterioration
- Improve operational reliability
- Extend the lifespan of the lifeboat
- Reduce replacement costs
- Ensure compliance with international maritime regulations
- Maintain crew and passenger safety
Common FRP Lifeboat Damages
FRP repairs are commonly required to rectify:
- Hull cracks
- Gelcoat damage
- Impact damage
- Collision damage
- Structural fractures
- Delamination
- Surface wear
- Water ingress
- Stress cracks
- Deck damage
- Seat and canopy damage
- Corrosion around fittings
Early identification and repair prevent minor defects from developing into major structural failures.
Comprehensive FRP Lifeboat Repair Process
Damage Assessment
Every repair begins with a detailed assessment of the damaged area.
Our inspection may include:
- Visual inspection
- Structural assessment
- Non-destructive testing (NDT)
- Thickness measurement
- Crack analysis
- Delamination inspection
- Impact damage evaluation
This enables engineers to determine the most suitable repair method while maintaining the original structural integrity of the lifeboat.
Surface Preparation
Proper preparation is essential for a durable repair.
The damaged section is prepared by:
- Removing damaged laminate
- Cleaning contaminants
- Grinding the repair area
- Drying affected surfaces
- Preparing bonding edges
- Creating suitable surface profiles
This ensures maximum bonding between the existing structure and new repair materials.
High-Quality FRP Repair Materials
Marine-grade materials are selected based on the manufacturer’s specifications and repair requirements.
These include:
- Fiberglass cloth
- Chopped strand mat
- Woven roving
- Epoxy resin
- Polyester resin
- Vinyl ester resin
- Marine fillers
- Structural core materials
- Gelcoat systems
Using quality materials restores the original strength and durability of the lifeboat.
Lamination & Structural Repairs
The damaged area is rebuilt using controlled lamination techniques.
The repair process includes:
- Resin preparation
- Fiberglass lay-up
- Multi-layer reinforcement
- Resin impregnation
- Air removal
- Structural consolidation
- Surface finishing
Each repair is carried out in accordance with manufacturer recommendations and internationally accepted repair practices.
Curing & Final Finishing
After lamination, the repaired area is allowed to cure under controlled conditions.
Final finishing includes:
- Surface sanding
- Gelcoat application
- Colour matching
- Surface polishing
- Cosmetic finishing
The repaired section is blended seamlessly with the original lifeboat structure.
Inspection, Testing & Quality Verification
Following completion of repairs, the lifeboat undergoes detailed inspection and functional verification.
Testing may include:
- Visual inspection
- Structural integrity checks
- Water-tightness inspection
- Functional testing
- Load testing (where applicable)
- Final quality inspection
Only after successful verification is the lifeboat returned to operational service.
Davit Winch System Overhaul
The davit winch system is responsible for the safe launching and recovery of lifeboats during emergency situations. Continuous operation, corrosion, lack of maintenance, and aging components can reduce system reliability.
Regular overhaul restores performance while ensuring safe and dependable operation.
Initial Inspection & Assessment
The overhaul process begins with a comprehensive inspection of:
- Winch drum
- Gearbox
- Brake system
- Electric or hydraulic motor
- Bearings
- Shafts
- Wire rope
- Control mechanisms
- Structural supports
This allows engineers to identify worn or damaged components before repairs begin.
Complete Winch Overhaul
The winch system is dismantled for detailed inspection and refurbishment.
Services include:
- Component cleaning
- Gear inspection
- Brake overhaul
- Bearing replacement
- Seal replacement
- Shaft inspection
- Corrosion removal
- Mechanical refurbishment
- Replacement of worn components
All replacement parts meet OEM specifications wherever applicable.
Lubrication & Reassembly
After refurbishment:
- Bearings are lubricated
- Gearboxes are serviced
- Brake systems are adjusted
- Fasteners are torque checked
- Alignment is verified
- Moving parts are lubricated
Proper lubrication improves efficiency and extends equipment life.
Testing & Commissioning
Before returning the winch system to service, comprehensive testing is carried out, including:
- Functional testing
- Brake testing
- Operational testing
- Load testing
- Dynamic testing
- Safety verification
Testing confirms that the complete launching system operates safely and efficiently.
Documentation
Complete service records include:
- Inspection reports
- Repair details
- Replacement components
- Test results
- Maintenance recommendations
- Certification records where applicable
Accurate documentation supports future maintenance planning and regulatory compliance.
