Technical Report: FPU Trunojoyo 01
Developed by OceanSTAR Elite Group

1. Introduction

This report provides a technical overview of the Floating Production Unit (FPU) Trunojoyo 01, developed and operated by OceanSTAR Elite Group through PT Timas Oceanstar Indonesia. The unit supports offshore gas production in the Madura Strait, East Java, Indonesia, and represents a significant milestone in the company's transition into upstream asset operations.

2. Project Background

The Trunojoyo field development required a floating production solution capable of processing and delivering natural gas under offshore conditions. OceanSTAR Elite was awarded the project under a full EPCIC (Engineering, Procurement, Construction, Installation, and Commissioning) contract scope.

The FPU was designed to:

• Process raw gas from subsea wells
• Treat and compress gas to pipeline specifications
• Export processed gas to onshore facilities

3. Design Specifications

3.1 General Particulars

• Vessel Type: Floating Production Unit (FPU)
• Length Overall (LOA): ~160 m
• Breadth: ~32 m
• Accommodation Capacity: Up to 70 personnel

3.2 Processing Capacity

• Gas Processing Rate: ~175 MMscf/d

3.3 Process Systems

The topside facilities include:

• Inlet separation system
• Gas compression system
• Gas dehydration unit
• Metering and export system

3.4 Utility Systems

• Power generation units
• Firewater and safety systems
• Instrument air and control systems
• Telecommunications and navigation systems

4. Engineering and Construction

The FPU was fabricated at a shipyard in China and completed within approximately 15 months, demonstrating accelerated project execution despite pandemic-related constraints.

Key engineering highlights include:

• Modular topside integration to reduce construction time
• Compliance with international offshore design standards
• Optimization for maintainability and operational efficiency

5. Installation and Commissioning

5.1 Offshore Installation

• Transportation to Madura Strait: Completed September 2022
• Offshore hookup and integration with subsea infrastructure

5.2 Commissioning Performance

• Commissioning duration: ~30 days post-installation
• First Gas Achievement: 23 October 2022

The short commissioning timeline reflects effective system integration and pre-commissioning strategies.
6. Operational Performance

Since start-up, FPU Trunojoyo 01 has demonstrated strong operational reliability:

• Availability: 100% uptime (reported period)
• Safety Performance: Zero Lost Time Injuries (LTI)
• Stable production output meeting design capacity

These metrics indicate robust system design, effective maintenance practices, and strong operational management.
7. Health, Safety, and Environmental (HSE) Considerations

The FPU incorporates multiple safety-critical systems, including:

• Emergency shutdown (ESD) systems
• Fire and gas detection systems
• Passive and active fire protection
• Hazardous area classification compliance

Operational procedures emphasize:

• Risk-based inspection (RBI)
• Preventive maintenance
• Workforce safety training and compliance

8. Strategic Significance

FPU Trunojoyo 01 represents:

• OceanSTAR Elite's first operated offshore production asset
• A successful transition from EPC contractor to asset operator
• A key contributor to Indonesia's domestic gas supply

The project establishes a technical and operational benchmark for future offshore developments undertaken by the company.
9. Conclusion

FPU Trunojoyo 01 demonstrates effective integration of engineering design, accelerated construction, and high operational reliability. The project highlights OceanSTAR Elite's capability to deliver complex offshore production systems under challenging conditions while maintaining strong safety and performance standards.
The successful deployment and operation of the unit position the company for continued growth in offshore energy infrastructure and production operations.
