Ezra's subsea services division EMAS AMC will conduct mooring repair work on a floating production, storage and offloading facility in west Africa, as well as working on a deepwater pipeline installation project in the South China Sea.
The pipeline project will include the installation of flowlines and associated pipeline end terminations and spools in water depths of up to 1400m.
Work for the contracts is expected to begin this month.
Meanwhile, Ezra's offshore support division EMAS Marine will strengthen the company's presence in the Asia Pacific through contracts for support work in Malaysia, Thailand and Australia, using two anchor handling tug and supply vessels and one platform supply vessel.
"These are important wins for us as it strengthens our presence in west Africa and growing leadership in Asia," Ezra group CEO Lionel Lee said.
"The subsea project in the South China Sea is also a clear recognition of the deepwater pipelay capabilities of our subsea team and our key assets here in Asia.
"The Asia Pacific region is an important market for us with offshore support, subsea construction and engineering activities expected to continue picking up as oil field operators venture further offshore."
The contract wins follow a $100 million contract to carry out subsea transport and installation work for Apache Energy's Coniston development at the North West Shelf last month.
The company's order book stands at more than $2 billion.
