What We Do

  • Hull plating replacement — phased removal and replacement of aluminum or steel hull sections while maintaining structural integrity with temporary shoring
  • Crack repair & stop-drilling — identification, preparation, and repair of fatigue cracks in hull plating, frames, and structural bulkheads
  • Frame & stringer reinforcement — sistering, doubler plates, and gusset additions to restore or upgrade structural members
  • Transom & stern repair — structural transom reinforcement, swim platform integration, and rudder post support work
  • Grounding & impact damage repair — hull damage assessment and structural restoration after grounding events, collision, or dock strikes
  • Pre-sale structural inspection welds — targeted repair of documented deficiencies identified during pre-purchase survey
  • ABS survey documentation — complete weld procedure, material traceability, and inspection records for classification society requirements

Why DolFab for Hull Work

Lloyds, ABS & USCG, Certified Welders
Individually qualified welders — not just a shop certificate. Qualification records, WPS documentation, and material mill certs provided with every structural job.
Superyacht-Scale Experience

Full In-House Support
Hull work is backed by our CNC waterjet cutter for precision plate cutting, press brake for forming, and rolling machine for curved sections — complex jobs completed without subcontracting.
45+ Years in Marine
Since 1978, every type of hull material and failure mode. We've seen problems that surprised the original builders. Nothing here is new territory.

How We Work on Hull Repairs

Every structural job follows a documented process. No shortcuts on hulls.

1
Assessment & Scope
We come to the vessel. Visual inspection, templating, thickness measurements, and sometimes ultrasound — whatever it takes to define the scope accurately before a dollar is spent.
2
Material Procurement
We source plate or extrusion to the correct alloy spec with mill certifications. For classified vessels, material traceability starts at the steel service center.
3
Fabrication & Welding
Plate cut on our CNC waterjet, formed on our press brake or rolling machine, then welded to ABS procedures. Multi-pass welds visually inspected between passes.
4
Documentation & Handoff
Complete documentation package: weld procedures, welder qualification records, material certs, and inspection reports. Ready for surveyor review at handoff.

Superyacht Hull Repair FAQ

What hull repair work does DolFab do?

We handle aluminum and steel hull plating replacement, crack and fatigue crack repair, frame reinforcement, and structural weld restoration. Work is done to Lloyds, ABS & USCG standards with full classification documentation provided.

Can you do hull repairs while the vessel is in the water?

Minor repairs can be done on-vessel with proper staging and access. Significant structural hull work typically requires drydocking for proper access and quality control. We work with local Fort Lauderdale boatyards to coordinate drydock schedules.

Do you provide documentation for hull repair surveys?

Yes. Every structural hull repair includes engineering assessment, weld procedure documentation, welder qualification records, and non-destructive testing (NDT) reports as required by the classification society or surveyor.

How do you handle corrosion damage repair?

We assess the full extent of corrosion before proposing a repair scope. Blasting, weld prep, and structural welding are all done in-house. We use marine-grade filler alloys and apply proper surface treatment to prevent recurrence.
