UTM and steel supervision

Ultrasonic thickness measurements (UTM)

Pursuant to the international rules of classification societies, all vessels are subject to periodical survey in connection with the technical condition of the hull. In the course of survey, the hull is inspected for deformations, cracks or structural breaches, and the obligatory measurement of residual thickness of the hull structures. The results of survey and measurements are compared with a relevant normative value. Based on obtained results costumer receives a full picture of jobs required/recommended to be done on a board. Residual thickness of hull structures is carried out by the most popular way of UTM

Our technicians are top-ranking experts with comprehensive training and tuition received. Most of them have higher education in the field of shipbuilding and ship repair. We have all the necessary documents and certifications to operate worldwide. Inspection and survey can be carried out on a best customer preference, either pre-docking inspection or dock straight ahead in a short notice. Reporting documentation prepared accordingly, and always submitted to the customer immediately upon completion of survey.

Repair sketches and steel replacement calculation

Appropriate training of technicians enables us beside from reports on the actual condition of the vessel, provide the client with repair sketches and suggestions, and calculate the weight of the metal to be replaced by reference to specific features of ship repair technologies. Pre-conducted survey of the vessel and proper calculation of weights of the structures to be replaced enables our customers to be better prepared for docking work, take into account all aspects when budgeting and to avoid pitfalls.

Pitting corrosion detection and measurement

Pitting corrosion or pitting wear of metal can develop on any ship structure. This issue is most common for ballast and cargo tanks. Pitting corrosion undetected and without measures taken on time can lead to costly repairs, lengthy downtime of the vessel and to environmental hazards. Our technicians have a considerable expertise in pitting corrosion research. Upon completion of inspection, they will provide a detailed report on location of the problem areas, their depth and extensiveness, together with appropriate repair suggestions based on requirements and tolerances of classification societies and IACS rules.

Anchor chains calibration

Starting from the second special survey of the vessel (10 years from the date of construction), the classification society representative may also request calibration of the anchor chain to ensure the total wear is within a normal range. Our UTM teams can perform this job both during the preliminary inspection or during dockage and prepare appropriate reports along with replacement suggestions for all parties concerned.
