CDLM is specialized in a wide range of river and maritime services, from inspection to completion, covering the entire West African region:
Bathymetry is the science of measuring the ocean’s depths and relief to determine its topography.
The CDLM offers precise bathymetry operations, which allow us to:
Maintenance work on engineering structures
Most of Senegal’s quays are over 30 years old. Regular and appropriate maintenance is therefore necessary to ensure the structure’s sustainability, which generally requires between 25 and 50 years of depreciation.
To this end, we regularly intervene in:
Where necessary, CDLM supplies and installs quay fenders. In the case of structures that are not accessible by land, barges equipped with cranes provide these services. CDLM has carried out fender installation work for the Port of Dakar, the French Navy and the supply and installation of fenders at the French Navy’s large wharf.
Cathodic protection of structures
The CDLM supplies and installs cathodic protection or special impressed current protection for maritime river structures (bridge piles, sheet piling, dams, etc.). Our specialists can conduct a pro-cathodic study beforehand to define the type of cathodic protection required.
Laying of optical fiber cables
CDLM has assisted the installation of most transcontinental optical fiber cables serving Senegal.
Some of our projects:
Engineering structure inspection
It is essential to appraise and control a work of art in order to control the durability of the structures and the safety of the users. These studies and underwater inspections allow the project owner to plan the maintenance work necessary for the good performance of the works and the deadlines. The study report is composed of a detailed plan, execution methodologies, photo and video report, and finally recommendations. Within the framework of certain studies, coring work on the partly underwater quays is carried out and then analyzed in the laboratory in order to determine the good performance of the concrete.
The CDLM regularly carries out small to medium-sized dredging operations using a suction hopper, a submersible pump or a long arm excavator mounted on barges.
Some of our dredging projects:
Staff provision and equipment hire
When it comes to major port or bridge construction projects, the CDLM regularly provides construction teams, scuba divers and equipment such as barges, launches, excavators, loaders, truck cranes, etc. Please contact us for a detailed list of staff and equipment we can provide.
