While casting the propellers of ship as a known fact small pores and tiny cracks would most of the times arise within the material and this would lead to failure if not revamped appropriately.
Till this date, defects have been tested manually and most of the times it is difficult to accomplish consistency as well as positive results by applying manual processes. Henceforth, to overcome this issue MPR in collaboration has arrived with a specialized systems office. It has developed a novel automated ultrasonic system to inspect marine drive components such as ship propellers.
Specifications and features of the automated ultrasonic system
- A small lightweight measurement system is used with a mobile scanning device.
- The system includes all hardware and software components including instrument control, motion control, data acquisition, fast imaging of A-, B- and C-scans, evaluation and documentation tools.
- The system is capable of recording large amounts of digitized ultrasonic testing data in real-time.
- On-site, the system currently scans an inspection area up to 900 x 450 mm and achieves speeds up to 200 millimeters per second.
- The mobile inspection system can be freely positioned on the propeller geometry; alternatively the scanning device can be attached by suction cups in vertical and horizontal positions.
- The mobile inspection and scanning system is available for on-site inspections in foundries, at propeller manufacturers and in dry dock.
- The use of the system reduces the time for defect inspection and makes the interpretation of the results far easier and more reliable.
MPR will be present at the SMM exhibition in Hamburg this year in Hall A5 on stand no. 421, where they will be exhibiting as part of S-T Diesel and Marine Group.
