Life extension is the process of extending the Unit’s ability to continue operating for extra years.  

As an asset reaches its initial design age or decommissioning age, a life extension study (LES) can be conducted to assess its condition and fatigue. This provides a cost-efficient option for safely extending the life of existing assets. LES are flexible and adaptable to the needs of individual clients and assets but must be considered in advance in terms of inspection planning and timeline. 

We at Zener have conducted quite a few LES for our clients worldwide. The typical project scope would include preparation of a Life extension work scope, Condition Assessment Survey, Schedule and Resource calculation, Engineering and Compliance support, Corrosion Protection, Project Management and Site Supervision. 

This study primarily consists of the inspection of the vessel’s current status and structural analysis to determine its capacity to operate beyond its shelf life. Apart from LES, we have also been involved in repair and maintenance of the vessels. Some of the work scopes executed by us are Steel renewal in tanks, Installation of reinforcements, Renewal of piping systems on deck and for modules, Outfitting replacement, Installation of additional accommodation after carrying out strength analysis, Electrical Maintenance works etc.
