Engineering

SELF PERFORM design and detail engineering with assistant from reputable Engineering company as required

Fully licensed software to support DDE and construction engineering.

Covers offshore and onshore facilities including platforms, modulle, jackets, pipelines, process equipment and instructure.

PROCUREMENT

To further guarantee quality assurance and client confidence, our procurement activities are supported by internationally recognized third-party inspection agencies, including DNV, Lloyd’s Register, Moody International, and other reputable independent inspectors, ensuring transparency, compliance, and uncompromised quality throughout the supply chain.

Procurement is more than purchasing — it is strategic supply chain management. We secure high-quality materials, equipment, and services through a global network of trusted partners, ensuring cost efficiency, timely delivery, and strict compliance with project specifications. This enables our clients to reduce risk while maintaining project continuity.

With extensive knowledge of material and equipment specifications across the Oil and Gas Industry, Mining Industry, and Infrastructure Industry, we are well-versed in international standards such as ASME, API, and BSI. This expertise allows us to ensure every procured item meets the technical, regulatory, and operational requirements of the project.

FABRICATION & CONSTRUCTION

Construction is where strategic planning is transformed into tangible results. We deliver comprehensive construction services with an unwavering commitment to safety, quality, and execution excellence, ensuring every project is completed on schedule, within budget, and in accordance with the highest international standards.

Building on this capability, we provide integrated fabrication and construction solutions for both offshore and onshore industries. Our expertise covers the development of offshore platforms, floating facilities, process equipment, industrial plants, infrastructure, and supporting buildings. By combining advanced fabrication capabilities with disciplined field execution, we ensure every structure and facility is delivered with exceptional quality, engineering precision, and long-term reliability.

With a highly experienced workforce and proven project management practices, we are equipped to execute complex projects in demanding environments, delivering solutions that support operational efficiency, asset integrity, and sustainable performance for our clients.

PRE-COMMISSIONING, COMMISSIONING & START-UP

Supported by experienced specialists and proven methodologies, we ensure each asset is handed over fully tested, operationally reliable, and ready to achieve optimal performance from day one.

Pre-Commissioning, Commissioning, and Start-Up are critical phases that ensure every facility transitions smoothly from construction to full operation. We provide comprehensive services to verify, test, and optimize systems, ensuring all equipment and processes perform safely, efficiently, and in full compliance with design requirements.

Our expertise covers the systematic preparation, inspection, testing, and performance validation of mechanical, electrical, instrumentation, and process systems across offshore and onshore facilities. Through structured execution and rigorous quality control, we minimize operational risks, reduce downtime, and accelerate readiness for commercial operation.

OFFSHORE INSTALLATION & HOOKUP

To support complex offshore installation and hook-up activities, we leverage the capabilities of the Indonesian-flagged DLB 3000T vessel, Gunanusa Hailong 106, a high-capacity asset designed for heavy offshore construction in demanding marine environments. This vessel is engineered to perform a wide range of offshore operations, including rigid pipe-laying, heavy lifting, and decommissioning works, enabling efficient execution of EPCIC projects across offshore developments.

With an overall length of 169 meters and breadth of 46 meters, the barge is equipped with a 12-point anchoring system, allowing operations in water depths of up to 300 meters. Its heavy-lift capability reaches up to 3,000 tons on the main hook and 1,000 tons on the auxiliary hook, making it suitable for the installation of large offshore modules, jackets, topsides, and subsea structures. Certified under ABS class standards, the vessel ensures operational safety, structural integrity, and compliance with international marine regulations.

In pipe-laying operations, the vessel is capable of installing rigid pipelines ranging from 4 inches to 60 inches in diameter, with advanced tensioning systems and dual stringer sections to support precise offshore pipeline installation in challenging subsea conditions. These capabilities enable reliable execution of offshore field development, subsea tie-ins, and infrastructure expansion projects.

Through long-term strategic partnerships, we continue to strengthen our offshore capabilities by expanding our fleet and bringing additional specialized assets to support future projects. This commitment ensures that we remain ready to deliver integrated offshore solutions with greater capacity, flexibility, and operational excellence for our clients.
