2007 - Hess, South Arne Project, Denmark
Summary
The South Arne field is a significant offshore oil and gas development in the Danish North Sea. The project involved platform modifications, subsea tiebacks, and enhanced oil recovery (EOR) techniques to extend the life of the field and maximize production. Given the challenging offshore environment, ensuring system reliability and process safety was a key focus.
Challanges
The offshore environment introduced extreme weather conditions, high wave loads, and temperature fluctuations, impacting equipment reliability and maintenance. The field’s aging infrastructure required comprehensive risk assessments to extend operational life. The integration of new processing units and subsea systems demanded a high-availability design to prevent production bottlenecks.
Solution
Conducted RAM analysis to assess production uptime and identify failure-prone systems, ensuring that equipment selection aligned with reliability targets.
Developed risk-based maintenance strategies, including condition-based monitoring for rotating machinery to predict and prevent failures before they impacted production.
Applied Failure Modes, Effects, and Criticality Analysis (FMECA) to evaluate aging infrastructure reliability and recommend optimized maintenance and replacement strategies.
Led functional safety assessments (SIL/LOPA) to ensure compliance with IEC 61511 and mitigate process safety risks associated with offshore operations.
