Offshore Pipeline Installation Services
Marine Pipeline Installation for Coastal & Offshore Projects
Union Dredgers & Marine Contracting (UDMC) provides specialised offshore pipeline installation services for marine and coastal infrastructure projects. Our capabilities cover the supply, preparation, installation, and commissioning of pipeline systems using materials such as HDPE, concrete, and GRP, supported by experienced marine personnel and specialised equipment.
Since 2007, we have supported pipeline-related works for projects including desalination plants, wastewater facilities, power plants, and other marine infrastructure developments. Our team manages key activities such as seabed preparation, trenching, pipe laying, welding and jointing, testing, and commissioning according to project requirements.
We can also integrate pipeline works with our Dredging and Marine Construction capabilities, providing coordinated support where projects require trench excavation, seabed preparation, coastal works, or related marine infrastructure activities.
End-to-End Pipeline Installation Solutions
From initial planning through final commissioning, our experienced team provides coordinated support for marine pipeline projects. We focus on safe installation, accurate execution, effective project coordination, and dependable performance in challenging coastal and offshore environments.
Our capabilities include:
- Pipeline supply and preparation
- Trenching and excavation
- Pipe welding and jointing
- Pipeline laying and installation
- Testing and inspection
- Final commissioning
Where projects require additional marine support, our Marine Services capabilities can complement pipeline installation with diving, inspection, surveys, and other specialist works.

Offshore Pipeline Capabilities
Pipeline Design & Engineering
Our team provides design support for offshore pipeline systems, including ballast blocks, general arrangements, intake structures, and diffuser arrangements. We develop project-specific solutions based on pipeline specifications, marine conditions, installation requirements, and operational needs, helping ensure that the system is practical to install, secure in service, and aligned with the overall marine infrastructure design.
Pipeline Material Supply
We can coordinate the supply of the materials required for offshore pipeline installation, including pipeline components, fittings, joints, ballast systems, and associated marine installation materials. Managing material requirements alongside installation activities helps maintain project continuity and ensures the required components are available according to project specifications and installation schedules.
Welding & Jointing
Accurate pipeline welding and jointing are essential for maintaining pipeline integrity during installation and operation. Our experienced team carries out joining activities according to project requirements, with attention to alignment, connection quality, and installation conditions. Proper jointing helps create reliable pipeline systems capable of performing effectively in demanding marine environments.
Dredging Works
Pipeline installation may require dredging and trench preparation to achieve the required alignment and burial depth. Our dredging capabilities allow us to support seabed excavation and preparation as part of an integrated pipeline installation scope. This coordination helps streamline marine operations and reduces the need to manage separate contractors for connected installation activities.
Installation & Commissioning
Our installation scope covers the positioning, laying, securing, testing, and commissioning of offshore pipeline systems according to project requirements. We coordinate marine operations and installation activities to ensure accurate placement and reliable system performance. Following installation, commissioning activities verify that the completed system is ready for its intended operational purpose.
Surveys & Drawings
Accurate surveys and technical drawings support effective planning and execution of offshore pipeline projects. Our capabilities include marine surveys, route information, installation drawings, and project documentation required to support pipeline alignment and construction activities. Where required, these services can also be coordinated with our wider Marine Services capabilities.
Industries We Support
Union Dredgers provides offshore pipeline installation solutions for projects serving desalination plants, wastewater treatment facilities, power plants, industrial developments, and other marine infrastructure. Our experience across government and private-sector projects enables us to adapt installation methods to different site conditions, pipeline specifications, and operational requirements.
Where a project involves related marine works, our Marine Construction and Dredging capabilities can provide additional support for seabed preparation, trenching, coastal works, and associated infrastructure.
Reliable Project Execution
Offshore pipeline installation requires careful coordination between engineering, material preparation, marine operations, installation, testing, and commissioning. Our experienced team works through each stage with a focus on accurate execution, efficient coordination, and compliance with project specifications. We aim to provide clients with a dependable installation process from initial preparation through final commissioning.
Health, Safety & Quality
Safety and quality are integrated throughout our pipeline installation activities. Project-specific planning, risk controls, experienced personnel, and quality checks help ensure that installation works are carried out responsibly and efficiently. We maintain close attention to marine working conditions, pipeline integrity, and environmental requirements throughout project execution.
