Stop losing money around blasting.

LaserGT helps drydocks and shipyards reduce the hidden cost layer around abrasive blasting, local steel repair and coating preparation.

We target the scopes where blasting, UHP waterjetting or mechanical preparation creates more cost, delay and disruption than the repair itself justifies.

And when the business case is right, LaserGT can scale with multiple laser units, parallel work fronts and high-power 6000W laser capacity for larger surface preparation areas.

  • Zero abrasive 

  • No cleanup 

  • No waste 

  • Less work-front disruption 

  • Scalable drydock execution 

  • High-power 6000W capacity 

  • Beam width up to 50 cm

Book Drydock Cost Review

Blasting may be fast on the steel. But slow for the dock as a whole.

For large open hull areas, conventional blasting can still be the right method.

But for local corrosion, weld seams, tank repairs, coating damage, difficult geometry, punch-list work and selected larger areas, the surrounding burden can be larger than the surface itself.

The direct blasting rate is only one part of the cost.

The real cost sits in the system around it.

The Visible Job The Hidden Cost Around It
Local corrosion Containment, access, cleanup, permits
Weld seam preparation Grinding hours, inspection delay, rework
Tank coating repair Ventilation, waste, confined space permits
Spot coating damage Blasting setup, masking, work-front closure
Punch-list before undocking Remobilization, waiting, late-stage disruption
Areas near other trades Dust, water, overspray, blocked work fronts
Larger selected repair areas Media volume, cleanup, waste, coordination burden
Multi-area drydock campaign Closed work fronts, sequencing issues, delayed handover

Where LaserGT Fits Across the Vessel

LaserGT is strongest on selected scopes where surface preparation creates more burden than the repair itself.

Hull spot repair and selected hull areas

For local corrosion, coating damage, weld zones and selected hull repair areas where blasting or waterjetting creates unnecessary containment, cleanup or disruption.

Tanks and ballast spaces

For selected tank and ballast repair scopes where abrasive media, water, sludge and cleanup become a major part of the job. Always under gas-free, ventilated and controlled conditions.

Piping, valves, brackets and supports

For local rust, coating removal and inspection preparation around complex geometry where blasting, grinding or waterjetting becomes difficult or creates excessive secondary work.

Repair sections and steel renewal areas

For surface preparation around steel repair, weld zones, modification areas and coating touch-up before inspection, coating or further work.

Dockside and yard equipment

For selected maintenance on cranes, loading gear, dock structures, rails, brackets and exposed steel equipment where rust removal or coating preparation is required with less dust, waste and cleanup.

Punch-list and late-stage repair

For selected last-stage repair scopes before undocking, where remobilising blasting or waterjetting can create unnecessary delay and work-front disruption.

Measure the real execution difference

LaserGT should not only be compared by square metres per hour.

The real comparison is the total execution model around the job.

  • Setup time

  • Manpower requirement

  • Access requirement

  • Containment requirement

  • Water handling

  • Sludge handling

  • Abrasive media handling

  • Spent grit cleanup

  • Work-front disruption

  • Surface readiness

  • Total closeout time

  • Scalability with multiple units

The fastest method is not always the method with the highest surface speed. It is the method that moves the vessel through the dock with the least total burden.

We do not just replace blasting. We reduce the cost layer around blasting.

Abrasive blasting is not just a surface preparation method. It is an execution model.

That model often includes:

  • Abrasive purchase

  • Freight

  • Storage

  • Handling

  • Compressors

  • Blast Pots

  • Hoses

  • PPE

  • Containment

  • Scaffold

  • Ventilation

  • Dust Control

  • Cleanup

  • Waste Recovery

  • Waste Disposal

  • QA/QC

  • Rework

  • Closed Work Fronts

  • Delayed Nearby Work

  • Delayed Departure

The abrasive invoice is not the real story.

The real cost sits around the job.

Laser surface preparation is not limited to small repairs.

The key is not whether laser can scale.

The key is where scaling creates better drydock economics than blasting.

LaserGT can be deployed as a scalable drydock method.

For selected larger scopes, we can increase capacity through:

  • Multiple laser units 

  • Parallel work fronts 

  • High-power 6000W laser systems 

  • Beam width up to 50 cm 

  • Dedicated laser operators 

  • Integrated safety zones 

  • Fume extraction and controlled execution 

  • Rope access, scaffold, MEWP or ground-based deployment

Scope Type LaserGT Approach
Small local repair One laser unit, compact crew, fast execution
Medium selected scope One or more units, planned work front
Larger surface area Multiple lasers in parallel
Broad surface treatment 6000W laser capacity with beam width up to 50 cm
Difficult access areas Rope access or adapted access method
Late-stage punch-list Rapid mobilization and selected repair
Multi-area drydock campaign Parallel laser teams across selected work packages

Hull-side preparation scenario: removing steps from the drydock model

A conventional hull-side preparation scope can require several separate steps before the surface is ready: scraping, waterjetting, UHP coating removal, water handling, sludge management, drying time and coordination around other trades.

In one representative drydock scenario:

2,400 m² required scraping and waterjetting to remove algae, marine growth and residues.

4,000 m² was the broader coating removal scope using UHP on the relevant exterior vessel areas.

The conventional route can take around 4 days.

LaserGT changes the execution model.

With the right equipment setup, high-power laser capacity, planned work fronts and trained operators, LaserGT targets this type of selected hull-side preparation scope in approximately 2 days.

The commercial value is not only speed.

It is the removal of entire process steps:

No abrasive media.
No spent grit cleanup.
No water from the laser process.
No water handling from the laser process.
No sludge from the laser process.
No wet-surface delay.
Parallel work can continue nearby.

Conventional Execution LaserGT Execution
Scraping of algae and marine growth Controlled laser removal and surface preparation
Waterjetting creates runoff and wet residues Dry laser process with no water runoff, no residues
UHP coating removal creates water handling and drying considerations Laser coating removal on selected areas where technically and commercially suitable
Water collection and handling No water
Sludge and wet residue management No sludge
Drying time before next operation No wet-surface delay
Spent grit cleanup if abrasive methods are used No abrasive media and no cleanup
Larger exclusion zones around wet or abrasive work Parallel work can continue nearby
Approx. 4-day conventional route Approx. 2-day LaserGT target route
Multiple preparation steps before closeout Fewer process steps from preparation to closeout

*Execution time depends on coating type, surface condition, access, equipment setup and acceptance criteria. The 2-day target should be confirmed through a controlled drydock cost and execution comparison.

Built for selected scopes. Ready to scale.

LaserGT can start with a small high-burden scope, prove value fast and scale into larger drydock work packages.

Drydock Scope Why LaserGT Fits
Local corrosion repair Avoids heavy blasting setup for small areas
Weld seam preparation Controlled cleaning before inspection/coating
Touch-up after steel repair Fast local surface preparation
Ballast tank spot repair No abrasive media & water sludge
Difficult geometry Better fit for selective treatment
Sensitive equipment areas No dust and water impact
Rope access scopes Smaller access footprint
Punch-list before departure Rapid selected-scope execution
Emergency repair No setup burden
Larger selected coating areas Can scale using multiple laser units
Broader surface treatment 6000W laser with beam width up to 50 cm
Multi-area drydock campaign Parallel work fronts reduce total schedule burden

The relevant question is not only how fast the steel is cleaned.

The relevant question is how fast the vessel moves through the dock with the least disruption to parallel work.

A small repair should not become a large operation.

A 50 m² local corrosion repair can look simple on paper.

But with conventional blasting, it can trigger containment, access, media handling, cleanup, waste disposal and work-front restrictions.

With LaserGT, the same selected scope can be approached with a smaller execution footprint, controlled local preparation and minimal abrasive waste.

Conventional blasting route

  • Blasting contractor 

  • Containment 

  • Scaffold/access 

  • Dust control 

  • Abrasive media 

  • Media handling 

  • Cleanup 

  • Waste disposal 

  • Work-front closure 

  • Inspection delay 

  • Rework risk

LaserGT route

  • Laser crew 

  • Local safety zone 

  • Fume extraction 

  • No abrasive media

  • No spent grit cleanup

  • Smaller execution footprint 

  • Parallel work nearby 

  • Faster selected-scope closeout 

  • Scalable with more laser units if required

The saving is not only in the surface preparation.

The saving is in the avoided burden.

Large Drydock Blasting Exposure

In a large blasting-intensive drydock, abrasive blasting can represent a major annual cost stack.

Item Scenario Estimate
Annual abrasive media volume 70,000 tonnes
Assumed abrasive cost AED 1,900 per tonne
Media purchase alone AED 133 million / USD 36 million
Direct media-related cost AED 192.2 million / USD 52.3 million
Core annual blasting burden AED 454.5 million / USD 123.7 million
Estimated full annual blasting burden AED 647.3–894.2 million / USD 176.2–243.4 million

*This is a scenario estimate, not documented customer data.

The abrasive cost is only the beginning

The full burden includes freight, handling, labour, containment, ventilation, cleanup, waste, rework and disruption.

If LaserGT helps reduce even a small part of this burden on selected scopes or scaled laser work packages, the commercial value can be significant.

Built for hot-climate drydock execution

In Gulf drydock environments, heat, humidity, ventilation, PPE burden, access and long work-front closures make conventional surface preparation harder to manage.

LaserGT reduces the execution burden on selected scopes by removing abrasive media, water handling, sludge handling, spent grit cleanup and wet-surface delay from the laser process.

No abrasive media
No water from the laser process
No sludge from the laser process
No spent grit cleanup
Smaller controlled work fronts
Parallel work nearby
Better fit for selected local repair areas

Drydock managers

  • Use LaserGT when the job is:

    • Small 

    • Complex 

    • Local 

    • Late-stage 

    • Difficult to access 

    • Near other trades 

    • Expensive to isolate 

    • Waste-sensitive 

    • Schedule-critical 

    • Suitable for parallel laser work fronts 

Reduce off-hire risk.

Shipowners / ship managers

  • LaserGT helps reduce risk on selected drydock scopes by reducing the burden around local corrosion repair, coating damage, weld preparation, tank repair, larger selected areas and punch-list work.

    • Fewer surprises.

    • Less waste.

    • Less disruption.

    • Better drydock control.

Built for controlled surface preparation.

Coating / QA teams

  • We can document:

    • Surface cleanliness 

    • Surface roughness/profile 

    • Dust control 

    • Salt contamination where required 

    • Method statement 

    • Risk assessment 

    • Fume extraction 

    • Coating compatibility testing 

    • Adhesion testing where required 

    • Productivity by coating/rust type 

    No claims without proof. No coating work without acceptance.

Less abrasive. Less waste. Less secondary burden.

HSE / environmental teams

  • The method still requires proper laser safety, fume extraction and controlled execution.

    But for the right scopes, the total HSE burden can be significantly lower than conventional methods.

Cleaner execution is becoming a competitive advantage

Shipowners, operators and project stakeholders are increasingly looking beyond price and surface speed.

Waste, disposal, cleanup, environmental exposure, documentation and drydock efficiency are becoming part of the commercial decision.

Early adopters of zero-abrasive surface preparation can position themselves ahead of this shift.

Early adopters of this capability may gain a competitive edge in high-spec fabrication and maintenance environments where quality consistency, execution efficiency and environmental compliance are increasingly driving project awards.

Compare LaserGT with conventional methods

Method Strong where Weak where Hidden burden
Abrasive blasting Large open areas with established setup Small complex repairs, sensitive areas, late-stage work Media, dust, containment, cleanup, waste
UHP waterjetting Salt removal, large flat surfaces, no abrasive requirement Confined spaces, drying windows, poor drainage Wastewater, sludge, flash rust, drying
Mechanical grinding Very small repairs and weld touch-up Larger selected scopes, consistency-critical work Labour, fatigue, vibration, inconsistent quality
Vacuum/sponge blasting Sensitive areas where dust must be reduced Speed, cost, equipment footprint Consumables, recovery, slower production
LaserGT Local, complex and selected scopes — with ability to scale using multiple units and 6000W capacity Cases where blasting is already fully optimized and disruption cost is low Requires validation, safety controls and fume extraction

The relevant question is not only how fast the steel is cleaned.


The relevant question is how fast the vessel moves through the dock with the least disruption to parallel work.
