Leask Marine has proven capability in the design support and installation of nearshore marine infrastructure, including diffusers, intakes, and outlet pipelines.
Our marine operations team delivers turnkey solutions for utility providers, industrial facilities, and coastal developments, with a focus on precision installation and long-term structural integrity.


Our scope of work typically includes:
- Seabed Surveying & Pre-Installation Assessment – detailed hydrographic and geophysical surveys to verify seabed bathy metry, identify potential obstructions, and hazards.
- Seabed Preparation & Dredging – controlled dredging and grading operations to establish a safe, stable, and level foundation for landing and support structures.
- Placement & Alignment of Diffusers/Intake Heads/Outlet Terminations – deployment and positioning using specialist lifting, alignment, and subsea handling systems to ensure accurate placement relative to design tolerances.
- Subsea Concreting & Structural Stabilisation – placement of marine-grade concrete and grout to secure structures, mitigate movement under hydrodynamic loading, and provide long-term protection against scour and undermining.
- Environmental Safeguards – integration of best practice environmental management measures, including monitoring of water quality, protection of sensitive habitats, and adherence to local and national regulatory requirements.

By combining advanced marine plant, subsea construction techniques, and in-house engineering expertise, Leask Marine ensures that nearshore intake and outfall systems are installed to the highest standards of safety, durability, and environmental stewardship.
