The contracts cover engineering, procurement, construction, and installation (EPCI) services.
In addition, McDermott has won an "additional scope" on an existing contract in the Gulf.
"These projects combined are a substantial brownfield award for McDermott and have a total scope which includes the EPCI for jackets and topsides, subsea pipelines and subsea cables," McDermott said.
While McDermott did not name the client which handed out the contracts, it is understood to be Saudi Arabian national oil company Saudi Aramco which Upstream previously reported was set to hand McDermott three contracts.
