Introduction
Offshore assets often undergo decades of modifications, making accurate documentation essential for safe operations, maintenance, and future decommissioning. In many cases, however, legacy platforms operate without updated engineering drawings or digital models.
SixD Engineering recently completed a complex offshore project in the Central Africa region (Guinea), where an aging wellhead platform lacked reliable as-built documentation. Through advanced 3D laser scanning and intelligent modeling, our team successfully transformed the facility into a fully digitized engineering asset.

Project Challenge
The offshore wellhead platform had experienced numerous piping modifications and routing changes over the years. Unfortunately, these alterations were never formally documented.
As a result, the client faced several critical challenges:
Absence of updated engineering drawings
No reliable 3D models of the platform
Difficulty planning maintenance and modifications
Increased risks for future fabrication and dismantling activities
Without accurate engineering data, executing safe and efficient operations would have been increasingly difficult.

SixD’s Engineering Solution
To address these challenges, SixD deployed a comprehensive digital engineering approach combining high-precision laser scanning and intelligent 3D modeling.
Scope of Work
Our team executed the following key activities:
• 3D Laser Scanning of the complete offshore wellhead platform
• Point Cloud Processing and Registration to create an accurate spatial dataset
• Intelligent 3D Modeling (E3D) developed directly from scan data
• Generation of Isometric Drawings for piping systems
• Preparation of Bill of Materials (BOM) for fabrication planning
• Creation of a Structured Digital Asset Database for engineering reference
This workflow ensured the platform’s current configuration was captured with high accuracy and converted into usable engineering deliverables.

Project Objective
The primary objective of the project was to help the client build a complete digital engineering library of the offshore platform.
In the coming years, the platform is scheduled for decommissioning (dismantling). Having accurate digital documentation is therefore essential for:
Safe modification and maintenance work
Fabrication planning and replacement components
Improved asset lifecycle management
Efficient and risk-controlled dismantling operations
By digitizing the platform, the client now has a reliable foundation for all future engineering decisions.
