GRP & Structural

Structural issues do not stay localised.

Cracks, stress marks, and delamination are rarely isolated to the visible surface. They usually point to movement or stress elsewhere in the structure.

Understanding the cause properly means the repair is carried out correctly and holds over time.

We will review your enquiry and come back with a clear next step.

The cause sits beneath the surface

Cracks and visible defects are often symptoms of movement, stress, or structural loading elsewhere on the vessel.

Load paths that are not evenly distributed.

Areas of flex or movement.

Water ingress affecting integrity.

Without understanding the structure as a whole, repairs are only temporary.

Assessing load paths and structural movement

Why structural issues return

Most GRP issues we see onboard have been addressed before, but not fully resolved:

  • Surface repairs that never addressed the cause.
  • Stress or movement that was not identified.
  • Previous work that was not integrated properly.
  • Repairs that have not performed over time.

What looks resolved often reappears if the underlying issue remains.

A structured approach to structural work

We identify the cause, not just the visible damage, so work is completed efficiently and without unnecessary extension of yard time.

Pre-haul inspection and planning

We understand the issue before the vessel ever leaves the water.

Clear scope before lift-out

Defined work and not-to-exceed expectations agreed up front.

Coordination with yard and trades

One plan across every trade the repair touches.

Controlled execution once out

Work delivered to plan, documented, and built to hold.

Assess structural work properly

Understanding the cause before repair ensures the work is carried out correctly and avoids repeat issues.

GRP and structural services

We support a wide range of work, often carried out alongside other refit or repair projects.

Crack and stress repair

Resolving the defect and the movement behind it.

Structural reinforcement

Restoring strength where loading has exposed weakness.

Delamination repair

Re-bonding separated laminate back to a sound structure.

Water ingress correction

Stopping the path of moisture before it spreads further.

Surface preparation for refinishing

A sound, fair substrate ready for paint or gelcoat.

Part of wider refit projects

Coordinated with paint, running gear, and exterior works under one plan.

A typical structural repair

Recurring cracking in a high-stress area

We were recently asked to address recurring cracking in a high-stress area. Previous repairs had resolved the surface, but the issue kept returning.

Once the structure was assessed properly, it became clear that movement in the surrounding area was driving the problem. Correcting that let the repair hold without recurrence.

The fix addressed the cause, not just the symptom that kept coming back.

Fix the cause, not just the crack

Understand the structure before the repair, so the work is carried out correctly and you avoid repeat issues. Tell us what you are seeing and we will come back with a clear next step.
