Ship Hull Inspection

Ship hull inspection is a set of procedures including: visual inspection, measurement of residual hull thicknesses, detection of defects in hull structures, preparation of documentation and determination of the scope of work to restore worn areas.

In accordance with the Class rules, all ships undergo periodic surveys of hull structures: annual, intermediate, special, to establish the technical condition of the hull. When comparing the results and the requirements for the class, a conclusion is made about the suitability of the vessel for navigation and the need for repair.

Specialists of SpeсMorService carry out fault detection of hull structures, thickness measurements and develop recommendations for repair.

STAGES OF WORK

01

We raise the ship out of the water, put it in the dock on slipways. We divide the vessel into sections from the outside, number the frames, select the thickness measurement points, and prepare the surface.

vessel preparation

02

We are inspecting the ship’s hull. By the method of visual control, we reveal surface defects, deviations from the specified geometric dimensions and shapes. We check the condition of welds, cladding and hull structures.

visual inspection

03

We measure the thickness using ultrasonic devices, determine the depth of the dents and the degree of wear of structural parts. We examine the hull from bow to stern horizontally, from the keel to the peak point vertically. Thus, the chance of missing damage is minimized.

04

We compare the identified characteristics with the normative ones and generate the documentation:

Tables of measurements, on the basis of which the technical condition of the sections of the hull is determined
A drawing depicting the outer skin, on which defects are indicated by symbols: damage, dents, worn parts, elements requiring replacement.
Flaw detection report – a consolidated document signed by the commission that examined the ship and the Register employee.
