What we've done
Ensuring compliance & integrity
Structural Crane Survey
A client hired Tresmontana to conduct a structural crane survey to ensure the crane's structural and operational integrity.
The survey included visual inspections and non-destructive testing of key areas such as the Pedestal, Slew Ring, A-Frame, and Boom using Ultrasonics and Eddy Current methods.
Our engineer conducted all inspections in compliance with relevant standards, procedures, and acceptance criteria, and Rope Access was used as needed to facilitate inspection.
Throughout the survey, our engineer made several important observations, well documented, and promptly communicated to our client.
​
During the analysis of the Boom Foot Section, it was observed that coating breakdown and surface corrosion was present on Junction Boxes. Our engineer assessed and rated this deterioration, assisting the client in determining an appropriate corrective action plan.
Our engineer detected a hydraulic fluid leak, a challenging find for those without experience in spotting such issues. Luckily, our engineer possessed extensive expertise in this area and knew exactly what he was looking for.
​
Hydraulic leaks, if left unaddressed, can lead to hydraulic hoses bursting, causing complete system failure. The client was promptly notified, and these findings were thoroughly documented in the final survey reports, which were delivered upon completion of the inspection.
Container & Sling NDT
At the client's request, Tresmontana was assigned the recertification of Cargo Carrying Units (CCUs). These inspections entailed a comprehensive visual examination of the containers, focusing on corrosion, deformation, and in-service defects, with particular emphasis on the lifting points and critical load-bearing welds.
​
The initial responsibility for our engineer was to procure the necessary certification and verify its accuracy. Once this task was completed, a meticulous visual inspection was carried out.
The lifting points of the CCU are crucial, and the welds underwent meticulous examination. Our engineer conducted a comprehensive inspection of all lifting point welds using the Magnetic Particle Inspection (MPI) method of non-destructive testing (NDT) to ensure the absence of surface-breaking defects.
​
MPI is one among several technical NDT methods used in structural inspection to verify weld integrity.
Finally, the sling assembly underwent examination, which included a thorough visual inspection followed by a non-destructive testing (NDT) inspection of the master link set. Magnetic Particle Inspection (MPI) was utilised to detect any surface-breaking defects.
​
After completing all necessary inspections, comprehensive reports were compiled and furnished to the client, certifying the equipment for safe usage.
Lifting Equipment Survey
Tresmontana received a request from a client to perform an SI2307 Lifting Equipment Survey aboard one of their offshore assets. These surveys are conducted every six months as part of a periodic examination scheme.
​
Our engineer conducted visual examinations and function tests on both fixed and loose lifting equipment. Fixed equipment, including pad-eyes, runway beams, winches, and cranes, were thoroughly inspected by our engineer to ensure functionality and safety.
Coating breakdown and surface corrosion present significant challenges to the integrity of client assets. The British weather, whether onshore or offshore, can be harsh, especially for structural steel.
​
In the LOLER survey, our engineer identified several fixed equipment items affected by corrosion. The engineer assessed the extent of deterioration and provided ratings to help the client develop a plan to prevent further degradation.
Lifting Equipment Examinations encompass a wide range of items, from small ones like shackles to larger ones like cranes. In this specific survey, our engineer conducted a visual inspection and function test on an overhead gantry crane.
Our engineer noted several important observations, such as damage to cable trays and brackets, surface corrosion on critical components, and the hook safety latch seizing up. These observations were communicated to relevant parties and documented in final reports.
