SERVICES
FERSAH UNDERWATER SERVICES provides all of underwater heavy works since 1990 .
Our service categories are specify below.
 |
In order to benefit from the dilution and natural purification processes of the sea, Fersah carries out deep sea discharge projects with the discharge of wastewater to the seabed with pipes and diffusers at certain distances from the shores. HDPE, CTP, Steel and Composite pipelines of different diameters and lengths for the different demands of treatment plants, energy plants, biological, chemical and nuclear facilities are designed, manufactured and implemented successfully by our company. |
 |
|
HDPE and CTP pipes from the sea is purified by pumping the solutions under high pressure by keeping the salt and other impurities by using Reverse Osmosis technology. With the current state of technology, purification of water from the sea achieved by Reverse Osmosis method is much better quality and at much lower costs than distillation and other similar methods. Water intake system is also used in Thalasso Therapy pools, which make Spa use indispensable to benefit from the therapeutic and detoxifying effects of the heated sea water. |
 |
|
Our company provides installation of all kinds of underwater pipelines (HDPE, GRP, Steel Pipes) for transportation and transmission of drinking water, waste water, cooling water, chemical substances, petroleum, fuel oil, natural gas together with the project design, manufacturing and application services. |
 |
|
The method ensures, the proper removal of corroded steel marine structures, such as pontoons, underwater pipelines, piers and marine vehicles by underwater cutting.The disposel of wrecks and the installation of new reinforcements covers the installation process. Our company successfully executes underwater cutting and welding operations with the help of our expert diver staff and the latest technology equipment. |
 |
|
Marina and Port cleaning operations are performed by removing all kinds of materials that harm marine life, create pollution, create a danger to human health or disrupt the ecological balance in the sea and coastal settlements concerning ports ,marinas and their coastal areas by our expert industrial divers .While the appropriate products are recycled, the remaining wastes are disposed of successfully. |
 |
|
Our Company, within the scope of dredging activities, operates on maintaining or increasing the depth of navigation channels, anchorages, berthing areas – ports /piers in open seas, inland waters and channels including the cleaning process of sediments and debris from the bottom of lakes, rivers, harbors and other water bodies. We can achieve dredging in different depths and ground conditions due to our various technical equipments and scans are carried out successfully in ports and piers up to a depth of 50 m. |
 |
|
The wreck removal procedure begins after completion of all examinations before demounting and shearing of vessels which are submerged or semi-submerged, abandoned or inoperable under the water or on the surface with professional industrial divers. We begin to contain, clean and remove hydrocarbons and any other pollutants such as fuel wastes (fuel,gas,diesel) ,oil wastes (hydraulic and lubricating), tank washing waters, tank drainage system, asbestos, oily waters to help protect sensitive marine and coastal environments and eliminate safety risks. |
