Project introduction:<\/h2>\n\n\n\n

To ensure the integrity and reliability of critical static systems aboard the DP3-classed offshore floating accommodation unit, a major integrated offshore energy services company commissioned ABL to conduct a comprehensive Risk-Based Inspection (RBI) study. <\/p>\n\n\n\n

The project aimed to prioritise inspection efforts based on risk exposure, aligned with API 580\/581 methodologies, and to support long-term asset integrity planning<\/p>\n\n\n\n

As part of the RBI project, ABL delivered a full-cycle review covering system definition<\/strong>, damage mechanism evaluation<\/strong>, risk assessment<\/strong>, field validation<\/strong>, inspection planning<\/strong>, and CMMS integration<\/strong>. This included identifying static mechanical systems (cooling water and compressed air), assessing thinning, cracking, and external corrosion risks, applying a qualitative risk matrix (PoF and CoF), conducting onboard inspections, developing risk based inspection recommendations and formatting them for seamless upload into IBM Maximo.<\/p>\n<\/div>\n\n\n\n
