PT GUNANUSA UTAMA FABRICATORS (GUNANUSA) was founded by Mr. Iman Taufik in 1980. In September 1983 the company secured its first offshore platform Engineering and Fabrication contract for two Production Facilities topsides which were later installed in the Cinta Natomas field in the Java sea.
Today, after more than 20 years of successful operations, Gunanusa is renowned as one of the leading offshore oil & gas fabrication companies in the ASEAN region and the only company of its kind established and developed by Indonesian Nationals. The company's excellent track record includes turnkey projects in oil & gas particularly for offshore platforms for some of the world's famous oil companies like Total, British Petroleum, Pertamina, Chevron, ConocoPhilips, ExxonMobil, YPF Maxus, CNOOC, PetroChina, PTTEP, Hess, and ONGC.
Gunanusa has executed more than 100 contracts since its inception. Most recently, in December 2006, the company delivered two sets of platforms for BP's Tangguh field offshore Papua, Indonesia with a design life of 40 years; which meant that the structures had to be fabricated with extra long-term corrosion protection which is posed many difficult and new challenges for offshore platform fabrication not commonly faced by fabricators anywhere. The Company's success was achieved through unrelenting efforts by the management team that has enabled the company to obtain the ISO9001 certification from Lloyds Register in 1999 and a number of safety achievement awards. Most of the projects were executed without any Loss-time Accidents (LTA) and the best safety record achieved by the company was recorded in June 2006 with 20 million man-hours without LTA.
Amongst the projects undertaken by Gunanusa to date include 24 Production Modules, 35 drilling platforms and not less than 24 jackets. The company is also an ASME, U, U2 and S certified company for the manufacture of pressure vessels and boilers including electric dehydrators, separators, tanks, mechanical flotation units, heavy duty filters, water and waste treatment plants and waste heat expansion recovery boilers most notable of which were two units of 100 Mw HRSG (Heat recovery steam generators) which were shipped and installed in the New York city centre.
In keeping with its commitment to contribute towards the country's efforts in developing the local industry, Gunanusa is an active member of the Indonesian business and industrial community and participates actively in the Indonesian Chamber of Commerce and Industry (KADIN), Association of EPC Contractors (GAPENRI), Association of General Contractors (GAPENSI), Federation of Machinery and Metal Working Associations (GAMMA) and Indonesian Shipbuilding Association (IPERINDO).
As part of a project to increase electricity supply to the City of New York, Alstom Power Inc hired Gunanusa to fabricate two identical 100MW Heat Steams Recovery Generators (HRSG), each weighing 2500 tonnes and has a 40 m height. We completed the fabrication in 8 months in April, 2005, loaded the modules to a dockwise vessel using multi wheels method, and shipped it through the Panama Canal to Queen,NY
The BP Indonesia operates Tangguh gas field in Berau Bay in the province of Irian Jaya, Indonesia. The natural gas field contains over 500 billion m3 (17 Tcf) of proven natural gas reserves, with estimates of potential reserves reaching over 800 billion m3 (28 Tcf).
Hess operates the Ujung Pangkah area at East Java in shallow water at 10 m depth. Gunanusa has been awarded to perform Engineering, Construction, Hook Up and Commissioning of Central Processing Platform (CPP) and Auxiliary & Utility Platform (AUP).
The project scope of works is the Engineering, Procurement, Construction, Commissioning and Installation of the ICP-R platform, Flare Tripod and connecting bridge. The ICP-R platform consist Main Structural Frame, Building Module, Process Module, Turbo Generator and Compressor Module which has a weight of 7300 MT and the jacket weight is 3600 MT. The Flare Tripod topside weight is 90 MT and the jacket is 630 MT.The water depth is 75 m.
For Peciko Offshore Developments Phase 3, Gunanusa fabricated the new Satellite Wellhead Platform (SWP-G) and 20" sea line connection SWP-G and the existing MWP-A, and also the modification to existing facility (MWP-A). The plant design life is 20 years. The construction and installation, completed in October,2002, include the deck (1200 tonnes) and jacket (800 tonnes).
Peciko Offshore Development Phase 4 EPSC 2 contract entails the fabrication of 2 satellite wellhead platforms with 4 legs (SWP E & K), the decks weight are 970 and 850 tonnes. The jacket for the decks are 800 and 720 tonnes.
PTT Exploration and Production Plc (PTTEP) operates the Greater Bongkot South (GBS) gas field in the Gulf of Thailand. For the Development Phase 4a of GBS, Gunanusa has been awarded the contract for Supply and Installation of Quarter Platform South (QPS) and Flare Platform South (FPS), with the scope of work to perform Engineering, Procurement, Construction, Installation, Hook Up and Commissioning.
Total E&P operates the Peciko gas and condensate field at the offshore of East Kalimantan, with a water depth from 30m to 50m, south of the Mahakam River Delta. Peciko Development Phase 6 is an onshore project consisted of turbo-compressors, inlet and discharge gas air coolers, suction and discharge scrubbers, pressure vessels, accompanying pipelines and civil works. The project will took 21 months and will be completed in 4th quarter of 2009.
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.
Total Indonesie 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.
The North Compression Platform for Tunu Development Phase 8, weighing at 5400 tonnes, is the largest platform Gunanusa ever fabricated to date. The NCP would allow the North Tunu area to operate in MP mode. The platform comprises of inlet slug catcher, air cooler, condensate export pumps and turbo-compressors. The project was completed in September, 2002.
