The Canadian company SNC Lavalin has signed a long-term deal for commissioning services across a portfolio of upstream projects operated by Petroleum Development Oman (PDO), Your Oil and Gas News reported.

The move marks both the expansion of SNC Lavalin’s operations in the Sultanate of Oman and the efforts by PDO to implement new contracting models in order to pare costs.

According to OilPro, the services will be of particular importance to Oman over the coming three to four years, as the firm’s two mega projects approach completion.

In early March 2016, the Canadian company’s wholly-owned subsidiary Kentz Overseas Company was awarded a five year contract by PDO to provide commissioning support services. The support services were agreed to include covering full systems completions, commissioning and start-up management, planning, consultancy, supervision, execution and administration of various oil and gas related facilities across a number of major projects.

Additionally, SNC was recently awarded a contract for the construction of an Omani petrochemicals scheme, as well as long-term engineering services agreements with the state energy companies of Qatar and Saudi Arabia.
