Offshore Oil & Gas Future Development

MHS is building client’s ‘CONFIDENCE’ !

(Source NST) KUCHING: For the second time in three months, a helicopter en route to an offshore oil facility has crashed into the sea, this time off Bintulu.

ANPGA Platform. Picture taken just after DB30 Complete all Heavylift works.

The first commercial hydrocarbons from the Angsi field were produced in December 2001 via the Angsi complex, which comprises a central processing platform bridge-linked to a wellhead platform. Production rates are expected to climb from an initial 15,000b/d of oil and 60mmcfd of gas to peak volumes of 65,000b/d and 450mmcfd.

Example of Flexible FlowLines

• Installation of 500m 6″ Rigid pipeline (Original design was Flexible Flowlines) from KRA-2x Subsea wellhead to KRA-S (South) subsea wellhead.
• Installation of 4 nos of spools tie in at KRA-2x & KRA-S
• Pre-Commissioning of the newly installed 6″ line.
• Assistance during introduction of hydrocarbon to the newly installed pipeline.

Looking forward to execute the job since i’ve never been working in Natuna field before.

Below is the list of typical activities during Installation of Riser. Assume the work is executed using typical 8 point mooring pipelay barge.

• Set up at location. (Riser Installation Pictures)

• Assume barge is ready for riser mode. ‘Ready’ means, completed the pipeline laydown activities, stinger has been deriged, all davits installed & riser material is already onboard and ready for riser fabrications.

• The work executed by sat divers (Assume waterdepth 60m). Typically there are minimum 4 davits line to be connected to the pre-installed chocker slings on pipeline & 1 line connecting pulling head to the main crane block.

• Here is where the pipeline is being picked up until the pulling head is around 10m above MSL (Mean Sea Level). Upon confirmation by surveyor, the pipelay barge will move (pipeline sidewalk) until the pipe is align with the proposed installation route. Again, confirmation by surveyor is required.
• The pipline then is being lowered down and CLIENT to confirm the final pipeline route (Aslaid) (more…)
