Project Description

The Tangguh UCC (Upstream Compression and Capacity) Project, executed by Damit Worley Parsons for British Petroleum (BP), Indonesia, involved the engineering design and analysis of modular structures supporting key process and utility systems for BP’s major LNG development in Papua Barat.

The project scope included the design and detailing of modular pipe racks, pipe bridges, and cooler support structures, optimized for both onshore installation and sea transport to the Tangguh LNG site. The modular concept required precise engineering coordination to ensure structural integrity, transportability, and ease of assembly during offshore and site erection.

Key engineering deliverables included:

• 3D modeling and structural analysis of modular pipe racks, bridges, and equipment support frames.

• Design for multi-modal transport (land and marine), considering lifting, sea-fastening, and load-out conditions.

• Foundation design and interface detailing for modular assembly and integration.

• Preparation of fabrication drawings, lifting studies, and construction sequences in compliance with BP’s global design standards and Indonesian regulations.

The project emphasized safety, modular efficiency, and cost optimization, ensuring a seamless transition from design to construction. This modular engineering approach contributed significantly to BP’s objective of achieving faster project delivery, enhanced quality control, and reduced site construction risks for the Tangguh LNG expansion.
