It took some time for all the parties to adapt to this new way of working, especially with the large contracts. Some contractors had misgivings about the guarantee clause, and one dropped out of the bidding process. The others adapted fairly well, and we were able to implement the plan successfully. Costs dropped steadily every year. The physical appearance of the plant improved dramatically, and the contractual inspections proved valuable.

Local contractors coped very well with the intermediate packages, and a strong link was established with the local community.

The ability to tackle urgent work with our own staff proved a great advantage and it helped retain competencies. We used our workers to monitor the work quality of the local contractors as well, reducing the workload on the supervisor.


Clear strategies help manage external corrosion issues effectively. A lifecycle approach is necessary, and long-term planning is well justified.

Under the right conditions, they can be designed to provide benefits for both parties.


  • 1. Specifying end results rather than intermediate results can help harness the knowledge, experience, and ingenuity of service providers.
  • 2. Providing limited infrastructure support to contractors can reduce costs for both contractors and the company.
