All objects and installations located and working under water are exposed to external factors, damage or even degradation. Professional inspection of underwater installations and periodical underwater inventory reviews of some engineering and water facilities not only mean the verification of their technical and visual condition, but also often allow to eliminate the risk for human life, environment and equipment by indicating defects or faults of the structures and facilities at an early stage of their formation.
PERFORMANCE OF UNDERWATER WORKS
The scope of underwater and hydro works carried out by UXO Marine:
removal of accumulated dust, sand or silt and cleaning of shoreline intakes
assessment of the technical condition of hydro-engineering structures
inspections and repairs of underwater vessels
inventories of underwater works
excavation of broken or stuck parts of agitators
underwater installation and drilling and anchoring of concrete
underwater cutting of steel structures by ultrathermal or oxy-arc method
execution of underwater concrete plugs
laying of geotextiles, prefabricated elements and gabion baskets
analyses and pre-execution studies of investments
sappering works including clearing areas and water areas from ferromagnetic objects and PWiN
prospecting and excavation of navigation obstacles
elimination of shallows under water by means of flushing or extraction of excavated material to the surface.
UNDERWATER INSPECTIONS - METHODS AND SOLUTIONS
UNDERWATER INSPECTIONS INCLUDE SERVICES OF ASSESSING THE CONDITION AND CHARACTER OF THE SEABED AS WELL AS DETECTION AND IDENTIFICATION OF DUMPED OBJECTS LOCATED IN A SPECIFIED AREA. THEY ARE OFTEN A REQUIREMENT PRECEDING INVESTMENT PROCESSES IN MARINE INFRASTRUCTURE.
UXO Marine provides subsea inspections in the offshore industry on commission, based on the experience of its team of geophysicists and divers, using specialist software (such as Oasis Montaje, Magpick or Sensys) and top quality sounding equipment and telecontrol solutions – both inspections of the seabed and inspections of underwater technical infrastructure, such as installations, platforms and pipelines, whose location on the seabed often changes naturally and which are constantly exposed to external factors.
SEABED EXPLORATION AND THREATS TO AQUATIC ENVIRONMENT
UXO Marine specializes in research and inspection work. Their implementation involves the use of various solutions to support, and even – often replacing the work of a team of specialists in dangerous and risky situations:
magnetometer probe systems towed by research vessels
remotely operated unmanned underwater vehicles ROV (Remotely Operated Vehicle) - submerged, staying and moving under water, used to a large extent for research purposes due to the possibility of equipping them with a light source, magnetometers, sonars or video signal recorders
autonomous unmanned underwater vehicles (AUV), scanning the seabed based on pre-programmed instructions to a given depth below the bottom and identifying objects as dangerous
The use of underwater robots significantly improves safety standards of underwater works. Their use is particularly important in dangerous, harmful, inaccessible or difficult-to-reach areas. Remotely Operated Unmanned Underwater Vehicles (ROV), equipped with additional measurement accessories, such as a multibeam probe, magnetometer, enable:
performing a very detailed inspection of the seabed
locating dumped objects, including dangerous ferromagnetic objects such as unexploded ordnance, dumped chemical or conventional weapons
determining the location of hazards to measuring equipment
mapping of the bottom profile with elements of underwater installations
monitoring the movement of underwater objects
Each underwater inspection is preceded by a professional selection of measurement methods. Upon its completion, the Client receives full and reliable documentation of the works carried out.
Inspections of objects located on the bottom or walls of water reservoirs. Underwater repairs, including repairs, underwater cutting and welding and assembly works of underwater parts of objects.
