SINGAPORE – Hallin Marine has won a pipeline services contract for an unnamed project offshore northwest Java.
This calls for installation of new control taps and a bypass for the main pipeline, which supplies 60% of Jakarta’s gas needs.
Hallin will provide full saturation-diving services from the Ullswater subsea operations vessel, which will be equipped with an ROV for subsea observation and process monitoring.
Also on location will be the DSV Carlisle, which has a Hallin-designed/built modular SAT system permanently mounted on deck. Other features include DP-2 dynamic positioning, accommodation for 126 personnel, and a four-point mooring system.
Hallin teams on the two vessels will perform removal of concrete coating on existing pipelines, pipeline integrity checks, spools installation, pre-commissioning assistance, installation of hot-taps at various locations, and the fitting of underwater pipe-closure stopples.
