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

We've repaired hulls on vessels up to 330 feet. Access, sequencing, and working inside large vessel spaces is routine for us — not a problem to figure out on your job.

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.

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.

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.

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.

Documentation & Handoff

Complete documentation package: weld procedures, welder qualification records, material certs, and inspection reports. Ready for surveyor review at handoff.
