Reliable and Accurate Determination of Life Extension for Offshore Units

摘要

As offshore units near the end of their design life, Operators are often faced with the requirement of extending the operating life of the facility, either to continue producing from an existing and still productive field, or to pursue new opportunities and/or defer new CAPEX as is often the case with MODUs, construction and support vessels and leased production units. Life extension presents a unique engineering challenge from the perspective of risk management; requiring a complete structural re-assessment of the facility, from its current, as-is condition in order to determine the remaining life of the unit, along with any repairs required in order to achieve the desired additional service life.
