Underwater Maintenance and Inspection Services
Vessels Solutions
When it comes to complex underwater ship repairs, maintenance and inspections, ELMANCY can handle it. Our experienced dive teams will exceed your expectations in terms of speed, quality, and safety. We are available worldwide 24 hours a day, 7 days a week.
We strive for excellence in everything we do.
Underwater in situ ship repair maintenance & inspection performed worldwide by ELMANCY reduces and avoids off-hire time for vessels. Our technical team works closely with our operational teams to respond quickly and deploy equipment on customer demand within 24 hours along the Mediterranean & Red Sea.
Class approved underwater CCTV inspections performed by ELMANCY certified commercial dive inspection team. These underwater CCTV inspections are performed as an alternative to a dry-docked inspection.
Underwater CCTV inspections are performed by ELMANCY class approved underwater construction and vessel inspectors using surface supplied air and specialized inspection equipment. The underwater inspection is carried out by certified commercial dive inspection teams using surface supplied air with an attending surveyor to detect significant damage. The inspection strategy includes the inspection of all items that would normally be inspected if the vessel was dry-docked.
Under water repair & coating (UWR&C) systems are designed to protect and seal metallic & concrete substrates that are immersed in seawater.
Based on the most advanced solvent-free epoxy resin technology, the product range is suitable for manual, mechanical & hydro-blasting applications.
The products are designed to fully cure under water without sacrificing adhesion and abrasion properties. They can be used to repair damaged or worn surfaces under water or along the surface.
Using up to the world’s largest underwater propeller repair apparatus, specially engineered for severe bend blades caused by ice or impact damage, damaged propeller blades are completely straightened underwater by a cold static load pressing operation performed by an operations team from ELMANCY bringing the blades back to as close as possible to their original design to restore optimal performance and efficiency to the propeller.
These operations are typically performed underwater without the use of the ship to carry the damaged part out of the water during ship operations or on site in tip ship condition to avoid or reduce off hire and downtime on a vessel.
With a wide range of welding and cutting equipment and qualified personnel, ELMANCY Services can complete your work safely and effectively.
Our certified and experienced wet welding divers can provide you with all the welding procedures and testing you need for all your works.
Many of our underwater welding professionals have a fabrication experience and are experienced with underwater welding in any environment.
We have extensive experience with sacrificial anode welding, cathodic protection welding, weld on piles and sheet pile, class approved underwater welding works related to ship repairs, and more.
Our cutting equipment is made by Broco and includes cutting jobs such as pile removal, sheet pile removal, demolition, pipeline removal, underwater obstructions, and more.
In order to assist with inboard repairs, ELMANCY specializes in blanking sea chests / plugging of intakes / overboard discharges.
This is a cost-effective way to replace defective valves and repair sea chest plating while on-board during normal ship operation.
In addition, ELMANCY has a great deal of experience maintaining the anodes of box coolers while on-board. We work closely with our suppliers to provide a full solution for class approved overboard valve replacement from their extensive stock. We guarantee getting you back on-time.
The cofferdam design consists of a bolted steel ring surrounded by a flexible membrane. The steel ring is connected to a hexagonal spudcan. The spudcan covers the bottom of the steel ring, and the ballast tanks are integrated.
This design reduces the weight, manufacturing cost and clearance of the steel ring compared to the all steel construction. A secondary sealing system was installed in addition to the primary cofferdam. Inflatable seals were installed inside and outside the steel ring to further reduce the risk of leaks.
If your speed logs or speedlogs appear to be faulty, we will exchange them worldwide to keep your vessel running. In the unlikely event that your current speedlog or speedlogs are out of production, we will provide and install new transponders with the correct housing, using our cofferdam & class approved dryweld techniques to install your new transpondering system.
The total replacement time for these systems is usually under 24 hours, with no downtime or drydocking. This is a cost-effective solution that gets you back on track in no time.
All of our qualified and experienced anode inspectors are able to perform underwater anode inspections under all visibility conditions, so you can rest assured that your boat will be back in working order in no time.

NDT MPI Crack Testing
The purpose of MPI crack testing is to determine the size of a fracture in ferrous metals that are not visible to the naked eye. When the extremities of a crack are found, stop drilling technique or other additional preventative measures are often needed. You can perform MPI crack testing wet or dry using our MPI UV crack testing system ELMANCY. With the right equipment and trained personnel, MPI cracking can be completed quickly and efficiently. Some cracking can extend above or below the water line, and this can be done with our MPI systems. The identified linear indication is documented using underwater photography and real time video.
NDT Metal Thickness Measuring
Underwater Metal thickness measurement is often used to compare the current condition of a structure to its original design, whether for a Class or Intermediate Survey of Submerged Objects. At ELMANCY, we use calibrated approved metal thickness gauges for precise underwater metal thickness measurement in digital readout, supported by underwater photography and video.
Eddy Current
The most common applications of eddy current relate to the inspection of in-service welded structures. These structures are subject to cyclical loading which can cause fatigue cracks to spread to critical welded locations. The most common application of eddy current relates to the inspection of welds which are subject to surface cracking defects. The detection of surface cracking defects by eddy current can be achieved through relatively thick coatings up to 2 mm in thickness. In order to detect surface cracking defects underwater, several scans of the individual welds must be performed in order to ensure that the defect is not overlooked. It is an operator dependent technique.
