Sixense conducted a detailed structural diagnosis for Vale’s Dry Ore Storage 2 facility, assessing the condition and performance of key assets. Our analysis provided actionable insights to support maintenance planning, improve operational safety, and extend the lifespan of the storage infrastructure.
Context
PT Vale Indonesia Tbk operates two dry ore storage at its Sorowako Process Plant – Dry Ore Storage 1 (DOS #1) and Dry Ore Storage 2 (DOS #2). Both facilities were built at the time of plant set-up in the 1970s. They consist of glue-laminated timber arch structures with timber purlins, clad with profile metal sheeting.
The DOS #2 has suffered a deterioration of its structure caused by environmental and operational activities.
Our Services
Prior to the design of the repair & protection works, the diagnosis aimed to provide an up-to-date overview of the condition of the glulam timber structures inluding:
- Defects type, severity and extent, pictures and mapping using DigitalSite
- Wood specie and strength class identification
- Wood hardness and humidity conditions
- Overview of the quality and condition of the connections, secondary elements and the structure
