UTM,Defectation of the hull

According to rules of Russian Maritime Register of Shipping all ships must pass ship hull condition evaluation (annually, in two years, in four years as well as extra) in order to estimate ship hull condition. In each survey it is necessary to define the runout of ship hull what is measure of the hull thickness and comparing it with the allowed minimum. The decision on repair is made on base of this comparison.

Specialists of IMPREZA SHIPPING SERVICE perform defects survey on ship hull constructions, measurements of ship hull thickness and work out recommendations on repair.

IMPREZA SHIPPING SERVICE holds certificates of approval issued by BUREAU VERITAS, DET NORSKE VERITAS, and RUSSIAN MARITIME REGISTER OF SHIPPING.

All Specialists of IMPREZA SHIPPING SERVICE has necessary qualifications according to international standards and are ready to perform ship hull measurements on ships located in ports and at sea.

The measurements of the hull thickness are made without damaging the wholeness of ship hull by method of ultrasonic thickness measurements. The core of this method is that the ultrasonic signals depending on time and speed are passing through the surface of hull, thus the thickness is defined. Measurements are performed by German equipment  RAUTKRAMER.

Measurements and defectation of hull constructions in pre-repair period gives a possibility to define future capacity of metal replacement reducing the docking time and minimizing customersí expenses.

Main steps of work

  • Preliminary discussion with classification inspector, contractor who performs ship hull measurements and ship owner representative to coordinate time-schedule and security measures
  • Visual inspection of ship hull details, its defects and places of measurements
  • Measurements of ship hull thickness, definition of deformations and other defects of ship hull constructions
  • Compare measured values with regulation values, work-out recommendations on repair
  • Report preparation and coordination it with survey inspector
