Hallin Marine, a Superior Energy Services company, has secured a project off the northwest coast of Java for the installation of new control taps and a bypass for the main pipeline which supplies 60 per cent of Jakarta’s gas requirements to the mainland.
Hallin will be providing full saturation-diving services using equipment built into the Ullswater subsea operations vessel. The Ullswater will be equipped with a remotely operated submersible vehicle that will be used for underwater observation and process monitoring.
The Carlisle, which was recently mobilized for duty as a diving support vessel, will also be on site.

The Carlisle has a Hallin-designed-and-built modular SAT system permanently mounted on deck. This is augmented by dynamic positioning class-2, 126-person accommodation and a four-point-mooring system. Hallin teams based on the two vessels will be removing the concrete coating on existing pipelines and performing pipeline integrity checks, spools installation, pre-commissioning assistance, installation of hot-taps at multiple locations and the fitting of underwater pipe-closure stopples.
“Hallin won the contract on the basis of its successful track record as an experienced offshore support service-provider and its knowledge in managing this type of project scope in the region,” said Hallin’s CEO, John Payne.
