  • Measuring of aquatic environment geophysical parameters 
  • CP measurements
  • Object search and recovery 

INSPECTION

Underwater video inspection is one of the most successful commercially developing services provided by JSC YUZHMORGEOLOGIYA. Инспектор Undetected flaws or hidden defects may lead to a disaster or wreck. Thus, a professional survey is a valuable preventive action and risk insurance.

Accuracy

Over a period of years, JSC YUZHMORGEOLOGIYA has been improving survey techniques to increase accuracy of our surveys. The companies deploying the underwater structures (underwater pipelines, terminals, vessels, outlet headers of treatment plants), get the precise information about the state of their property. Being well-informed our specialists are able to evaluate whether maintenance or repair is required.

Choice of the competent staff

JSC YUZHMORGEOLOGIYA is one of the companies, where advanced research procedures, skilled personnel and special-purpose equipment guarantee stable performance.

CP measurements are taken using the systems of contact and remote measuring methods (BUCKLEY and SUBSPECTION (UK) and with use of the acoustic and magnetic underwater inspection methods of pipelines, cable routes and geotechnical structures.

As a result of complex studies using the following tools:

  • Multi-beam echo-sounder and side scan sonar survey (onboard RV Yuzhmorgeologiya)
  • Two-head scanning profiler (“free span” measuring), providing the pipeline seabed profile (RT  1000 ROV)
  • Pipe burial depth measuring using the TSS440 pipe tracker
  • CP probe (RT  1000 ROV)
  • 3 camera high resolution color system (RT  1000 ROV)
  • Comprehensive digital system  for processing and archiving of TV and telemetry information (RT1000 ROV)

JSC YUZHMORGEOLOGIYA provides a complete data package, including quality control, description of procedures and data interpretation in accordance with international standards (DNV, IMCA etc.).  The final report form is agreed with the Customer.

Visual inspection

JSC YUZHMORGEOLOGIYA conducts underwater surveys and obtains digital images at a depth of 0 - 1000m even under low visibility, using the active impulse laser lighting system with backscattering rejection.

JSC YUZHMORGEOLOGIYA personnel are able to carry out surveys with surface control, using video cameras, mounted on ROVs. The survey may be carried out by 3 cameras simultaneously.  A ROV manipulator could be used if required.

Search

The successful search and recovery operation of the flight recorders from a crashed Airbus A320 became a good demonstration of JSC YUZHMORGEOLOGIYA capabilities in search and salvage operations.

Подъем "черного ящика"

The tragedy with Armavia plane occured in May of 2006. The plane with 113 passengers onboard crushed and sunk in the Black Sea into water over 600 m deep when landing in Sochi.  Strong currents and heavy sediment had quickly covered the wreckage removing all traces. It was impossible to locate visually the “black boxes” on the seabed.

The team of professionals from our company was able to solve successfully that problem. The salvage operation was conducted using the RT 1000 MRV, the light work/observation class vehicle rated to 1,000 meters and equipped with three video-cameras, six lights, a hydraulic manipulator with a special pump which able to clean sediments and plume from the buried recorders that were identified with use of the ROV-Homer (Sonardyne) direction guidance acoustic sensor specially installed on RT 1000. The recovery of the recorders was carried out with use of the hydraulic manipulator. It was the first salvage operation successfully performed by the Russian equipment at a depth of 600 meters.

JSC YUZHMORGEOLOGIYA has been а survey Contractor since the mid-90s. During that time, the company carried out more then 30 contracts. The main targets were underwater pipelines, cables, sunken objects, water treatment plants, unexploded war ordnance and harborage industrial debris.
