3D model of Huldra

**Overview**

Through the lifetime of an asset, Equinor is collecting large amounts of Life Cycle Information. This could be technical information, maintenance information or the 3D model of the asset. Equinor has a large portfolio of plant 3D models, which is continually maintained and updated by our contractors through the lifespan of the asset.One of these assets is Huldra. The field was developed with a wellhead and process facility, unmanned, and remotely operated from Veslefrikk B. Production started in 2001 and ended in 2014. The plant was decommissioned in 2019 and 97% of material recycled. The 3D plant model for Huldra is a result of Equinor early studies, and then matured in detail by contractor Aker Kværner and Rosenberg Verft in the construction phase of the plant. Equinor has then in collaboration with our contractors, maintained this 3D model through the lifetime of Huldra and used it to support all activities in operation maintenance and modifications.The 3D model now represents the as-built status of Huldra when it ended production in 2014. The 3D model, in addition to the visual appearance contain attributes as TAG, meaning that we can connect the 3D model with the correct technical from other Equinor systems. This is a key element in our digital twin solution that aims to connect data from different source systems.Equinor is using the 3D model as part of our digital twin development, development of Augmented Reality and Virtual Reality solutions and we want to enable others, to use the same data for innovations that could contribute to new ways of working.

**Huldra AVEVA E3D 3D model Data set**

The dataset consists of 3D Plant data created from the AVEVA E3D software. From this system we have exported 3 different file formats which is included in this dataset.

This is:

**RVM format (Native AVEVA Export formate, version E3D 2.1)**

The RVM dataset consists of:

- 69 RVM files
- 1 file pr. Area and discipline

**Navisworks file format consisting of (Navisworks Simulate 2016):**

The Navisworks dataset consists of:

- 23 NWD model files including one common assembly NWD. Husk å oppdatere med ny NWD fil uten utløpsdato før det publiseres
- 22 Tag files pr. As built area. (one area consists of all disciplines in the area)
- Tag files contains suggested STID tags in 3D and is needed for cross referencing to STID documents/tag

**FBX file folder contains (Exported from Navisworks Simulate 2016)**

- FBX Export settings:
- Camera off
- Light off
- Texture off
- Limitprimitives 0 (off)
- File format binart
- File versjon fbx2014

The FBX dataset consists of:
- 69 FBX format files with model data
- 69 TXT files with DB listing of attributes from AVEVA E3D (one pr. Area and discipline)
