IRON ORE TRANSHIPMENT PROJECT
Project Overview
Adept Engineering successfully delivered a comprehensive steel detailing package for a large-scale Iron Ore Transhipment System, designed to support high-capacity bulk material handling operations.
This project involved detailed modeling, coordination, and drawing production for multiple conveyor systems and transfer towers integrated within a marine vessel structure.
Key Highlights:
- Project Area: 75,614 sq. ft
- Total Structural Weight: 2,01,083 kg
- Completion Timeline: 10 weeks (post-approval)
- Software Used: Tekla Structures 2025
- Project Team: 8 members (Modelers, Detailers, QA/QC)
Scope of Work
The scope included detailed modeling and documentation of key conveyor systems and transfer structures:
- Starboard Side Deck Conveyor (STBD)
- Transfer Tower – STBD to Thwartship Conveyor
- Ship Deck Conveyor
- Transfer Tower – Thwartship to Port Side Conveyor
- Port Side Deck Conveyor
- Port Side Deck Conveyor Tripper
Each component required high-precision detailing to ensure seamless integration within the vessel’s structural framework.

Materials & Manpower
The project required coordinated execution across modeling, detailing, and QA/QC teams to handle:
- Complex conveyor structures
- High-volume part detailing
- Multi-stage revision cycles
- Fabrication-ready output delivery
Challenges & Engineering Insights
Complex Conveyor Integration
The thwartship conveyor system required intricate modeling as its structural frame was directly integrated into plate assemblies. This demanded precise coordination between structural and mechanical components.
High-Density Assembly Detailing
The tripper car frame assembly, spanning 37 meters, consisted of 792 individual parts per frame set, making it one of the most complex elements in the project.
- Initial detailing extraction time: ~3 hours per drawing
- Revision update time: ~45 minutes per drawing
Precision & Coordination
Maintaining consistency across thousands of parts and drawings required strict QA/QC workflows and version control to avoid fabrication errors.
Project Outcome
Adept Engineering successfully delivered a highly coordinated, fabrication-ready detailing package within the committed timeline.
