Flexible commercial model

From a commercial standpoint, McDermott offers a balanced and flexible contractual approach to each project based on the needs and preferences of the client and with the objective of balancing risk between contractor and client. While we continue to execute projects on a lump sum basis where it makes sense, we are contracting more and more projects on a "hybrid" basis, where a defined scope of work may be performed lump sum and the balance on a cost-reimbursable basis, which allows for risk sharing between the two parties. We also work on a purely cost-reimbursable basis as appropriate.


McDermott has the most extensive global experience of any tank construction company in the industry, having built in excess of 46,000 storage tanks under the CB&I brand in more than 100 countries on all seven continents.
