الهدم في البحر وتحت الماء: Underwater Demolition Dubai for Marine Concrete Structures
Introduction: Why Underwater Demolition Matters in Dubai & the UAE
Dubai and the wider UAE have one of the most intensive coastlines for engineered marine developments in the world: artificial islands, cruise terminals, marinas, offshore pipelines, water-theme projects and industrial jetties. Projects like peninsulas, breakwaters, marinas and island developments often go through upgrades, redesign or full decommissioning. plc-contracting.com+1
Whenever a quay wall, jetty, bridge pier, intake structure or seabed foundation needs to be removed or modified, underwater demolition becomes critical. It is more complex than land demolition: you have limited visibility, live tides and currents, tight environmental constraints and strict approvals from Dubai Municipality (DM), Dubai Maritime City Authority (DMCA), Trakhees and other regulators.

1. What Is Underwater Demolition & Marine Concrete Removal?
1.1 Definition
Underwater demolition is the controlled removal, cutting, breaking or weakening of structural elements that are fully or partially submerged in water – sea, lagoon, canal, harbor or reservoir.
In Dubai and the UAE, this typically covers:
- Reinforced concrete and steel piles
- Bridge piers and marine columns
- Caissons, dolphins and mooring structures
- Quay walls and sheet piles
- Breakwaters, revetments and armor units
- Submerged foundations of old jetties and platforms
- Underwater parts of intake / outfall structures and culverts
Many of these elements are linked to iconic projects: marinas, islands, waterfront mixed-use developments and industrial terminals. A typical scope combines:
- Topside demolition above water (slabs, beams, deck)
- Intertidal demolition (zone affected by tides/splash)
- Fully submerged demolition (divers / robotic / ROV work)
1.2 How Underwater Demolition Differs from Land Demolition
Underwater demolition is not just “normal demolition but wet.” Key differences:
- Limited visibility – divers may work in near-zero visibility; you rely on tactile work, sonar, cameras. Judux+2tmds.ae+2
- Hydrostatic pressure & buoyancy – as you remove concrete, uplift forces and water pressure change the behavior of the structure.
- Currents & waves – lateral loads on plant, lifting operations and access pontoons.
- Environmental constraints – strict limits on turbidity, silt plumes, noise and vibration to protect marine life and neighboring assets. Dubai Municipality
- Access limitations – most equipment must mobilise from barges, jack-up platforms, work boats or temporary causeways.
- Diving safety – decompression profiles, underwater cutting hazards, emergency procedures etc., governed by international and UAE marine HSE standards. hhadiving.com
Because of this, an underwater demolition package in Dubai is usually a hybrid engineering problem, combining:
- Structural engineering
- Marine construction and commercial diving
- Environmental and HSE planning
- Precision demolition, cutting and lifting
Stone Beam Demolition designs its marine/underwater solutions with that multi-disciplinary perspective from day one.
2. Typical Underwater Demolition Scenarios in Dubai & UAE
2.1 Island & Peninsula Redevelopment
Dubai’s coastal masterplans evolve: new peninsulas, rebranded beaches, upgraded marinas and reconfigured island shorelines. On such projects, underwater demolition may involve: plc-contracting.com
- Removal of old breakwaters and construction of new revetments
- Demolition of temporary jetties used for construction
- Adjusting quay walls to match new marina geometry
- Removal of underwater foundations of structures that are no longer needed
2.2 Port & Industrial Facilities
For ports, terminals and industrial marine facilities, underwater demolition supports:
- Replacement of deteriorated berths and fenders
- Removal of old loading arms, dolphins and pier foundations
- Decommissioning of intake / outfall structures
- Relocation of subsea utilities crossing channels
Offshore and nearshore industry references show how typical tasks include underwater demolition of piles, sheet piles and subsea structures in conjunction with lifting and explosive removal for some offshore scopes. Atlas Copco+2mydivetech.com+2
2.3 Bridges & Road Crossings Over Water
Demolition of bridge decks over canals or creeks is relatively common. Fully removing or partial cutting of piers and piles under water is more complex:
- Pile cutting at a specified level below seabed or channel bed
- Demolition of underwater pile caps, tie beams or crash walls
- Managing traffic safety and marine navigation during works
2.4 Theme Parks, Water Parks & Coastal Leisure Projects
Marine demolition can also be part of:
- Floating boardwalk or platform removal
- Underwater foundations of wave generators, ride supports or show structures
- Replacement of seawater pools and artificial lagoons
2.5 Emergency and Corrective Works
Occasionally, underwater demolition is needed urgently:
- Impact damage from vessels
- Scour or washout undermining structures
- Defective concrete requiring hydrodemolition repair rather than full replacement aquajetsme.com+1
Stone Beam Demolition plans both scheduled and emergency underwater works with clear method statements, marine traffic coordination and contingency options.
3. Regulatory & Permitting Framework for Marine Demolition in Dubai
Before any underwater demolition starts in Dubai, you must secure permits from several authorities. The exact combination depends on project location and jurisdiction.
3.1 Dubai Municipality (DM)
Dubai Municipality issues key technical guidelines and safety codes covering demolition, marine works and construction safety overall. Dubai Municipality+2Dubai Municipality+2
Typical DM requirements include:
- Approved demolition contractor license category
- Construction Safety Code compliance (scaffolding, lifting, equipment, work at height, etc.) Dubai Municipality
- Method statement and risk assessment submissions
- Waste segregation and disposal in line with circulars on construction and demolition waste. Dubai Municipality
In some zones (e.g., Dubai Development Authority/Tecom areas), demolition permits are processed via DDA but still align to DM technical standards. Dubai Development Authority+1
3.2 Dubai Maritime City Authority (DMCA) / Dubai Maritime
For any works near shore or offshore within Dubai’s maritime jurisdiction, DMCA requires a coastal or marine project permit, including demolition and removal of marine structures. Dubai Maritime Authority
Typical DMCA documentation:
- Application letter with full scope, drawings and coordinates
- Marine traffic management plan and navigational risk assessment
- Environmental protection plan (silt control, spill response, noise/vibration limits)
- Proof that the demolition contractor and diving contractor are properly licensed
3.3 Trakhees, Ports & Free Zones
In some areas (e.g., JAFZA, Nakheel, DP World, Port Rashid, etc.), Trakhees or the port authority may issue additional guidelines for marine construction and demolition. These often require:
- Approval of diving contractor
- Hot work and underwater cutting permits
- Coordination with port control and emergency services
3.4 Environmental and Survey Authorities
Depending on the location, you may need:
- Environmental Impact Assessment (EIA) or focused marine impact report
- Bathymetric and hydrographic data from DM’s Marine Information System (MIS) for design and verification Dubai Municipality
- Turbidity and water quality monitoring plans
3.5 How Stone Beam Handles Permits & Compliance
Stone Beam Demolition is structured to integrate regulatory steps into its planning:
- Early feasibility study identifies which authorities are involved.
- A combined engineering + HSE team develops permit-ready method statements, risk assessments and waste management plans aligned with DM codes. Stone Beam.ae+1
- Stone Beam coordinates with the client’s consultant to answer regulator comments quickly, avoiding project delays.
4. Technical Challenges of Demolition in Sea & Island Projects
4.1 Tides, Currents & Waves
In the Arabian Gulf, tides are moderate but sufficient to:
- Change water level by more than 2 m between low and high tide in some locations
- Create tricky access windows for intertidal work
- Influence the stability and mooring of barges and pontoons
For an underwater demolition plan, Stone Beam:
- Defines tidal working windows for critical tasks
- Chooses jack-up barges where a fixed platform is necessary
- Designs temporary works (e.g., braces, collars, cofferdams) to resist tide and wave loads
4.2 Structural Stability & Buoyancy
Under water, concrete and steel elements are partially buoyant. When you remove sections of piles or caissons:
- Load paths change – forces redistribute to remaining elements
- Uplift forces may cause unexpected movement
- Hybrid structures (part land, part marine) can behave non-linearly
Stone Beam’s engineers model phased demolition to ensure that:
- At every step, the structure has secure support and load path
- Temporary supports, bracing or strand jacks are installed before critical cuts
- Lifting plans consider submerged weight, added mass and hydrodynamic effects
4.3 Limited Visibility & Diver Safety
Many Dubai coastal locations have low visibility, especially near berths, dredged channels and industrial outfalls. Specialist diving companies in the UAE highlight how critical planning, communication and redundancy are for this type of work. tmds.ae+2mydivetech.com+2
Stone Beam’s approach:
- Use combined topside and underwater surveys: GPR and scanning above water, sonar and ROV below water where needed.
- Simplify underwater tasks so divers have clear, repetitive operations guided by precise templates or jigs.
- Reliance on video, sonar and positioning systems to verify cut positions rather than only diver vision.
4.4 Environmental Sensitivities
Marine demolition can release:
- Concrete fines and turbidity
- Rust and scale from old reinforcement
- Potential contaminants if structures are near fuel or chemical installations
Dubai’s emphasis on sustainable coastal development means you must limit and control these impacts. Atlas Copco+1
Stone Beam incorporates:
- Silt curtains and turbidity barriers
- Soft-start approaches for noisy operations
- Segregation of potentially contaminated materials for specialist treatment
4.5 Access, Plant & Logistics
You can’t simply drive a 70-ton excavator into the sea. Underwater demolition logistics may require:
- Work from marine plant – barges, jack-up platforms, work boats
- Temporary rock causeways / sand bunds
- Floating cranes and barge-mounted excavators
- Dedicated quay or laydown area on shore
Stone Beam works with marine logistics partners to optimize access strategies so the demolition program is realistic and cost-effective.
5. Main Methods & Technologies for Underwater Demolition
Underwater demolition uses a toolbox of techniques. The optimal combination depends on structural type, depth, access and environmental constraints. Stone Beam’s philosophy, as also seen in modern demolition method selection practices, is to choose methods based on engineering, environment and economics – not just tradition. SB Demolition+1
5.1 Diver-Operated Hydraulic & Pneumatic Breakers
Hydraulic and pneumatic breakers are widely used to demolish:
- Pier caps and concrete pile heads in the splash zone
- Localized areas of quay wall or apron slab
- Damaged areas of revetments and armor concrete
Specialized demolition contractors in the UAE note that these breakers can be highly effective in underwater applications when properly configured. alsarhtechnicalservices.com+1
Advantages
- Relatively simple technology
- Good for localised removal and shape adjustments
- Can be combined with topside excavators in shallow water
Limitations
- Can produce vibration and noise affecting nearby structures
- Slower than cutting when large sections must be removed
- Requires very careful diver positioning and safety
5.2 Underwater Diamond Wire Sawing
For precise, low-vibration cuts to concrete and steel piles, diamond wire sawing is a key technique. Marine contractors in the region use it to cut piles and sheet piles below seabed level or at a defined depth. mydivetech.com+1
Typical use cases:
- Cutting RC piles supporting a bridge or jetty
- Sectioning caissons into liftable blocks
- Cutting sheet piles at a specified elevation
Advantages
- Very low vibration – critical near sensitive structures
- Clean, predictable cuts
- Works on concrete plus steel reinforcement
Considerations
- Requires enough clearance to install wire around element
- Needs stable power supply and safe handling systems
- Precise survey and positioning are essential
5.3 Hydrodemolition (High-Pressure Water Jetting)
Hydrodemolition uses ultra-high-pressure water to remove concrete without damaging the reinforcement. UAE-based hydrodemolition providers highlight its strengths for selective removal and bridge or quay repair. aquajetsme.com+1
For underwater and marine applications, hydrodemolition is suited to:
- Removing damaged concrete cover while retaining rebar
- Selective removal where structural core must remain
- Intertidal or shallow underwater zones with specialized tooling
Benefits
- No microcracking in remaining concrete
- Minimal vibration – good near sensitive structures
- Easy to expose and clean rebar for repair
5.4 Underwater Burning & Broco Cutting
For steel structures – sheet piles, tubular piles, bracings, old dolphins – underwater burning (Broco, exothermic cutting, oxy-arc) is widely used. Commercial diving and marine maintenance companies in the region list underwater cutting and demolition as key services. Atlas Copco+3RONS Enviro Care LLC+3mydivetech.com+3
Applications
- Cutting steel piles at seabed or below
- Removing old fenders, ladders, brackets
- Segmenting steel decks or trusses
Risks & Controls
- Requires strict hot-work permits and gas monitoring
- Intense light and heat under water – PPE and training are critical
- Careful control to avoid damage to retained structures
5.5 Explosive Underwater Demolition (Special Cases)
In offshore oil & gas and some large subsea removals, controlled explosive charges are used to cut thick piles and jackets. Equipment rental and offshore support providers note “explosive removal and underwater demolition” as specific use cases. Atlas Copco
However, in near-shore Dubai environments, this method is usually restricted or avoided due to:
- Proximity to urban areas and sensitive structures
- Environmental and marine life protection
- Regulatory complexity
Stone Beam focuses on non-explosive methods for Dubai coastal projects, reserving explosive concepts only for very special regional offshore scopes and always through specialized partners.
5.6 Robots, ROVs & Remote Technologies
Land demolition in Dubai is already embracing remote-controlled robots for breaking in constrained or hazardous zones. arasarinternational.ae+1
For marine and underwater demolition, Stone Beam extends this logic:
- Use of track-mounted demolition robots on jetties, bridge decks and causeways to reduce risk to operatives.
- Integrating ROVs (remotely operated vehicles) and sonar for inspection, survey and, in some cases, small-scale cutting or tool handling.
- Combining real-time data (cameras, sonar, load cells) with engineering models for better decision-making.
5.7 Supporting Services: Inspection, Survey & Scanning
Successful underwater demolition relies on accurate information:
- Underwater inspection and condition assessments by commercial divers and ROVs Divetech+3tmds.ae+3Judux+3
- Bathymetric surveys and hydrographic data (MIS, multi-beam sonar) Dubai Municipality
- GPR scanning and concrete scanning above water to find rebar, PT cables, ducts and embedded services
- 3D laser scanning and BIM models of topside structures
Stone Beam is already strong in GPR scanning, concrete scanning and structural diagnostics on land; for marine work, this expertise is extended with specialist survey partners.

- Install temporary access (platforms, causeways, scaffolding, ladders).
- Set up monitoring where needed – settlement points, vibration sensors, inclinometers – especially near critical assets like sea walls or tunnels.
Step 6 – Topside & Intertidal Demolition
- Remove or weaken superstructure: slabs, beams, parapets, fenders.
- Use remote-controlled robots and excavators to reduce manual risk. arasarinternational.ae+1
- Prepare clean working front for diver activities – removing protrusions and obstructions.
Step 7 – Underwater Cutting, Breaking & Removal
- Divers or ROVs execute cutting and breaking sequences as per method statement:
- Install guides and templates on piles
- Perform diamond wire cuts or broco burning
- Use hydraulic breakers to free stubborn areas
- Each cut section is then rigged and lifted under the supervision of marine lifting specialists.
Key controls:
- Strict tool time logs for divers
- Real-time communication with topside crane and site engineer
- On-the-spot adjustments based on recorded loads and structural response
Step 8 – Waste Handling, Segregation & Recycling
Post-cut, sections are brought to shore for:
- Segregation of concrete, steel and other materials
- Recycling of concrete (crushed as aggregate) and steel (scrap yards)
- Special handling of any contaminated materials (e.g., old fuel-soaked concrete)
This aligns with Dubai’s increasing emphasis on demolition waste sorting and recycling. Dubai Municipality
Step 9 – Final Survey, QA/QC & Handover
- Conduct bathymetric survey to confirm removal of structures and debris. Dubai Municipality
- Provide as-built removal drawings and demolition records.
- Close-out with authority inspections and final sign-offs.
