Depriwangga is an independent technical service provider established in 1998. The company has developed a comprehensive portfolio centered on inspection, certification, engineering, and asset integrity management. While it serves a broad range of heavy industries including power generation, geothermal energy, and petrochemicals, Depriwangga maintains a significant operational footprint within the maritime and offshore oil and gas sectors. Headquartered in Jakarta, the firm supports complex energy and marine projects through a network of qualified engineers, surveyors, and technical specialists who ensure compliance with international standards and local regulations.
A core component of Depriwangga’s identity is its specialized engineering capability for offshore infrastructure. The company provides detailed design appraisal and analysis for fixed offshore platforms, covering critical phases such as transportation and installation. Its engineering teams conduct assessment and re-engineering studies to extend the life of aging marine assets, ensuring continued structural integrity in harsh oceanic environments. Beyond platforms, the firm’s expertise extends to subsea infrastructure, offering engineering services for underwater pipelines and flowlines that connect offshore production facilities.
In the realm of technical assurance, Depriwangga functions as a third-party inspection and certification body. It delivers statutory inspections and vendor surveillance to verify that materials and equipment destined for marine environments meet rigorous quality and safety criteria. This includes the validation of pressure vessels, wellhead equipment, and single point mooring (SPM) systems used in offshore loading operations. The company employs advanced non-destructive testing (NDT) methods, including ultrasonic and phased array techniques, to detect flaws in hull structures and piping systems without disrupting operations.
Complementing its engineering and inspection roles, the company offers extensive operation and maintenance (O&M) support. A key area of maritime relevance is its focus on lifting equipment. As a member of the Lifting Equipment Engineers Association (LEEA), Depriwangga performs inspections, load testing, and certification for offshore cranes, wire ropes, and heavy lifting gear essential for deck operations and cargo handling. Its teams also provide maintenance for mechanical and electrical systems on production facilities, ranging from valve repair to power distribution networks. By integrating design, verification, and maintenance services, Depriwangga acts as a critical partner in the lifecycle management of offshore and marine industrial assets.
