Inspection, assembly and maintenance of underwater installations

Just as inspections of ships afloat are carried out, our experience also allows us to carry out the inspection of installations and submerged structures such as piers, underwater emissaries, etc., using underwater high-resolution video systems and digital photography. To this respect, we carry out periodic inspection of submerged structures such as foundations, bridges, piloting, dolphin docks, piers, buoys, chains, anchorage equipment, tracks in shipyards or hydraulic power plants etc., allowing the early detection of possible anomalies.

After these inspections, a detailed report is always prepared supported with audiovisual material showing the evidences detected, as well as the repair work proposal. These inspection operations can be accompanied by repair operations and/ or maintenance of these elements either submerged or afloat.

GAMAR TECHNIEK Diving has the experience, the staff and technical equipment necessary to carry out assembly and installation as well as main-tenance with full guarantee of all the work executed, which can be done from land, or from the sea with support vessels.

Inspection activities, which are carried out, are essentially the following:

Ports and quayside berths blocks /caissons (drawers)/ piles.
Floating quays, fingers, floats and walkways.
Emissaries, collectors and submarine cables.
Water intakes.
Hydraulic power plants, dams and swamps.
Valves and gates and water intakes.
Pumping stations and water purification facilities.
Inland and marine aquaculture farms.
Fire extinguishing tanks and storm tanks.
Buoying systems for beaches, and/ or buoys.
Anchoring of buoys and other elements.
Doors, gates, valves, tracks and cars in dikes, shipyards and dry docks.

In the aforementioned inspections, faults or lack of maintenance can be detected on ships, so they would require repairs and maintenance services, either preventively and regularly, or due to breakdowns that must be repaired by urgent corrective actions. For which GAMAR TECHNIEK DIVING employs highly qualified divers with the needed expertise and skills as well as the means and technology to carry out these type of services. In relation to cutting and welding works and thickness measurement by ultrasound, to indicate that our staff has been trained and qualified by national institutions in this type of operations, in addition to complying with the IACS standards for evaluation of hulls. So we can offer all guarantees in the services that we provide, even in the most adverse situations, thanks to the work of our professionals.

Among the most relevant services we provide:

Repair and maintenance of propellers and rudders.
Cleaning and polishing to propeller.
Cleaning of manoeuvre propellers, seawater intakes, grids ( grills).
Release of propellers and shafts blocked by stands, ropes, nets, etc.
Horn closure repair, clearance measurements and axle drops.
Location and sealing of waterways, using putties, plugs and welding.
Welding of cathodic protections and thimbles.
Installation of printed current anodes Clogging of discharges for valve changes.
Installation and replacement of electronics (probes-projectors) on hull. Underwater measurement of thickness by ultrasound.

In addition, we are also specialists in control of both dry-docking and launching of all type of vessels in shipyards, dry docks and docks. And in these facilities we carry out the installation, inspection and maintenance of tracks and cars, as well as everything related to installation and maintenance of dock doors, gates and valves

Underwater Inspection of ships afloat

The Underwater Inspection of ships afloat is a service in which, through our experienced divers, we carry out a throughout examination and assessment of the hull of the ship. The extensive experience and qualification of our sta, combined with the use of the latest technology in vision systems (UHD), lighting, air supply and communication equipment from the surface via approved umbilicals and positive pressure helmets and masks, makes it possible to evaluate from the surface if the ship is in optimal navigable conditions for the safety of the ship, passage, cargo and / or crew, as well as an evaluation from an environmental and energy efficiency perspective.

These inspections are requested by the Ship Classification Societies, as well as by the relevant maritime authorities (Captaincy Maritime), in order to check the status of the ship hull without drydocking. GAMAR TECHNIEK Diving, like its collaborators, are certified according to the IWS "In-water survey " through which, they are able to carry out the inspection with professional divers and video filming equipment monitored on the surface. In this way we can assess if the ship is in the operational condition indicated by the certifica-tes and therefore all operations can be carried out safely.

The International Classification Society currently certifies GAMAR TECHNIEK Diving to carry out this type of inspections: Bureau Veritas. Within this service, we offer different types of inspections, depending on the client needs, such as:

Underwater inspection "In-water survey" Normally it is carried out with CCTV video and supervised live on the surface by the rating agency. The condition of the ship’s hull is inspected following class and stakeholder procedures.
Pre-docking inspection and / or sale-purchase In this type of inspections, possible damage to the hull and structural elements is analyzed, as well as assessing existing damages in order to prepare a repair plan prior to docking, or the evaluation of a sale.
Shipowner Inspection Through video or photography, our divers perform an inspection focused on the painting condition, cleanliness, structural damage, zinc anodes and marine life. All the collected parameters are analyzed allowing the client to make decisions.

In all these type of services, a detailed report is prepared adhering to the classification standards for all the examined elements, also including all video and audio recordings and photography submitted digitally.
