Coastal and Port Construction Solutions
Every dredging project requires a flexible dredging fleet. The required equipment varies depending on the hardness and composition of the seabed, such as clay, rock, schist, sand, and silt, as well as the water depth. Before starting any dredging operation, we evaluate the project execution phases and assemble the most suitable equipment for the specific scope, including floating excavators, bucket dredgers, dump barges, cutter suction dredgers, and other specialized vessels, ensuring full compliance with project requirements.
All equipment used in our operations is fitted with RKT and/or DGPS positioning systems, allowing real-time monitoring of whether the work is being carried out in the correct area and at the correct depth. This helps prevent operational errors and minimizes time loss.
All equipment used in our dredging activities is owned and operated within our organization and is available for 24/7 operation.
LCM ROTA Marine is a specialized dredging contractor with expertise in the following areas:
In parallel with the growth of international trade, the need for dredging in port maintenance and new coastal infrastructure projects continues to increase.
With global trade expanding, maritime transport has grown accordingly. To accommodate larger vessels, new ports are being constructed worldwide, and existing port infrastructure is being expanded. Dredging is essential for navigation channels, berthing areas, maneuvering zones, and land reclamation within port boundaries.
Ports and coastal structures are continuously exposed to sedimentation. Natural marine processes transport seabed materials into port areas and navigation routes, reducing usable depth. Rivers also carry alluvial materials that accumulate near deltas and coastal facilities. Over time, these processes prevent high-draft vessels from accessing these areas. Maintenance dredging is required to preserve operational depths.
Population growth has increased demand for coastal development. Residential areas, ports, and airports are expanding toward the sea. In many projects, dredged material is reused for reclamation, offering advantages in cost, time, and environmental impact.
Protective structures are required to safeguard coastal infrastructure from waves, erosion, and currents. Prior to construction, unsuitable seabed materials are removed and replaced with stable foundation materials through dredging.
Pipelines and cable routes are placed within trenches to ensure stability and protection. These trenches are created through dredging. DGPS systems ensure excavation accuracy in line with project specifications.
Dredging is used in industrial or polluted areas to remove contaminated sediments and restore water quality without harming the environment.
Dredging supports the maintenance of reservoirs used for hydropower and drinking water by controlling sedimentation and improving water quality.
Marine aggregates such as sand and gravel are essential for construction. Dredging is used to extract and transport these materials from designated borrow areas.
Dredging is the process of deepening, excavating, and preparing underwater ground using specialized equipment. The primary objective is to increase water depth and improve usability of waterways and coastal structures.
Before operations begin, seabed investigations are conducted. Based on the results, suitable equipment is selected. Excavated material is transported to designated disposal areas.
Our services support:
The selection of dredging methods depends on water depth, vessel size, and seabed conditions. Smaller equipment is used in shallow areas such as river mouths, while larger vessels operate in deep waters.
We perform dredging using:
Dredging involves removing and transporting materials such as mud, sand, and rock using machinery and pumps. Equipment selection varies depending on material type.
Key parameters considered:
Dredging vessels are specialized units designed for excavation and material handling operations. Depending on the project, different types are used:
After operations, dredged material is transported and discharged using:
Advanced monitoring systems ensure operational efficiency and accuracy.
