Total - Tunu Field Development Phase 11 South Compression Platform (SCP) and South Manifold Platform (SMP)

 

Total E&P operates the Tunu gas and condensate field in East Kalimantan on the outer margin of the Mahakam delta with an average water depth of 8 m. Total has awarded Gunanusa to perform Engineering, Procurement, Construction and Installation of almost all of the phases of the development.

For phase 11, this project consists of 2 platforms, South Manifold Platform (SMP) and South Compression Platform (SCP). SMP, weighing 2700 tonnes, consists of deck, Middle Pressure manifold with pig launcher and pig receiver, Low Pressure manifold, 2 slug catchers, and flare KO drums. SCP, weighing 4600 tonnes, consists of deck, inlet and discharge, air cooler, turbo-compressors, suction scrubbers for gas compressors, plant and instrument air systems, nitrogen production system, gas turbine power generator packages. SCP compressed the gas before delivery to Bontang LNG Plant. The project, which took 23 months was awarded in December, 2006.
