Marine & Offshore

problem: Ship hull steels and welds require good fracture toughness properties due to the possibility of brittle fracture in a low temperature service environment. The simple Charpy impact test gives only a qualitative indication of the material toughness.

Solution: Crack Tip Opening Displacement (CTOD) Testing

PTS can perform fracture mechanics toughness test to quantitatively measure fracture toughness of a full size specimen containing genuine crack at a loading rate more representative of service conditions. This would facilitate designers to perform a fitness for purpose analysis and calculate critical defect size to determine if cracked components can be used until it can be repaired.

problem: Repairs works at shipyards would require replacement of metal components within a fast turn-around time. It is imperative to obtain satisfactory alloy materials to be used for repair that is in accordance with the relevant shipping Class.

Solution: Positive Material Identification (PMI) – OES & XRF

PTS can provide on-site non-destructive techniques to quickly verify elemental composition and grade identification of alloys.
