Hallin Marine, a Superior Energy Services company, announces its return to the Natuna gas field off Indonesia. The project, for a major engineering procedure construction, installation and commissioning contractor, will be executed using the Ullswater subsea operations vessel. Total project value is approximately US$6 million.

“This latest Indonesian contract is scheduled to commence in June with an estimated duration of 30 days,” explains Hallin East Division managing director Rik Zwinkels. “It will centre on an offshore construction campaign to support the laying of 4,200 metres of flexible pipelines and the installation of rigid risers at the platform. The job scope includes  provision of project management and engineering services, saturation diving services, pre-lay survey using Hallin’s’ C-ROV work-class remotely operated vehicle and the pre-commissioning of the pipelines, using the subsea operations vessel Ullswater.

“Hallin has a proven track record in this type of flexible pipeline installation including a number of successful projects with our client. This has generated a positive relationship between the offshore personnel, project team and onshore staff of both organisations. Hallin is also an experienced and trusted partner in the Indonesian market.”
