Marine Construction

UNDER WATER MARINE CONSTRUCTION

We specialize in building and installing marine structures, combining technical expertise with high safety standards.

Installation of Piles

We perform underwater pile installation using hydraulic and vibratory hammers for marine structures such as piers, jetties, and offshore platforms. Our skilled divers and construction teams ensure precise positioning and secure anchoring in compliance with structural and geotechnical standards.

Cutting of Piles

Our underwater cutting services for piles include trimming and removal of excess or damaged pile sections. Using advanced mechanical and thermal cutting tools, we guarantee clean, accurate cuts even in low-visibility conditions, preparing the site for reinforcement or reconstruction.

Installation of Sheet Piles

We install underwater sheet piles (pale planches) for coastal reinforcement, cofferdam construction, and shoreline protection. These structures are essential for erosion control, land reclamation, and providing structural support for marine foundations.

Installation of Tetrapods and Protection Blocks

Our team handles the precise placement of tetrapods and heavy protective blocks along breakwaters and sea walls. These elements are designed to absorb wave energy and prevent coastal erosion. We ensure accurate underwater positioning and stability to guarantee long-term durability.

Installation of Scour Protection Blocks

We install anti-scour blocks at the base of marine structures to protect against erosion caused by water currents. These blocks reinforce foundations of bridges, jetties, and underwater pipelines, extending their lifespan and structural integrity in dynamic marine environments.

Installation of Recurring Anticipated Blocks

Our divers install recurring or pre-cast structural blocks that serve as foundations or reinforcement for future construction. These blocks are strategically placed to ensure alignment with anticipated load-bearing requirements and infrastructure expansions.

Installation and Repair of Quay Fenders

We install and repair underwater components of quay fender systems to protect vessels and dock structures during mooring. From rubber fenders to complex fender panels, our services ensure optimal shock absorption and long-lasting functionality.

Maintenance and Repair of Navigation Beacons

We provide underwater maintenance and repair of marine signal beacons, including mooring, electrical connection, and foundation stabilization. These aids to navigation are critical for maritime safety, and our interventions ensure they remain operational and properly secured.

Installation of Pipeline Systems

We specialize in the underwater installation of subsea pipelines for the transport of oil, gas, and water. Our team ensures accurate alignment, secure fastening, and protection of pipelines on the seabed using ballast blocks, trenching, and protective coverings. We adhere to strict international standards for subsea pipeline construction, ensuring reliability, flow efficiency, and environmental safety.

Question

Do You Have Questions About Our Marine Construction Services ?

01. What are the key steps in planning and executing a marine construction project?

Steps include site survey, engineering design, environmental assessments, permitting, mobilization of equipment, construction (e.g., piling, concrete placement), and post-construction monitoring.

02. What logistical and environmental challenges must be considered in marine construction?

Challenges include tides, wave action, weather, seabed conditions, and marine traffic. Environmental impacts such as sediment disturbance and marine life disruption must be carefully managed.

03. What standards or certifications are required for marine construction quality and durability?

Projects must comply with international standards such as ISO 9001, API, DNV, or ABS, and local environmental and construction codes. Certification ensures safety, compliance, and long-term durability.
