The contract involves the provision of the support vessel Windermere, an ROV, a diving team and a range of surveying and engineering services.

Hallin commercial manager Jonathan Quek called the deal a real milestone in Hallin's development and said it showcased the company's one-stop subsea solution.

"The scope of work includes providing a subsea diving support vessel to perform both diving and ROV services," he said.

"These will be used to complete a continuous subsea campaign of spools installation, inspection, repair and maintenance work in the eastern South China Sea.

"The project is scheduled to commence in 2014 and will have an estimated duration of six months including options."
