How virtual reality is used in industrial maritime design processes: Two case studies

Virtual reality (VR) is increasingly integrated into maritime design processes, and there is a need to better understand how it can support ship designers in their work. Through mapping and interviews, we investigated how VR was used in two design projects in the maritime industry. We explored two questions: What type of design activities and conversations were facilitated by VR as a collaborative medium? When VR was not selected, what other media were used instead, and for what reasons? We found that despite access to VR, most design conversations were facilitated by emails containing screenshots, visual interpretations, and text annotations. VR was used on a few occasions, together with executable files and flythrough videos made with real-time rendered models generated in a game engine, and a web-based 3D model-sharing tool. The use of VR as a collaboration medium was enabled by a variety of design activities ranging from field studies to 2D sketching and 3D modeling. The cases show how VR needed to be integrated with other forms of communication and was seen as a supplement and not the main communication channel for design. The cases also show that the pipeline required for VR scenes creation enabled other forms of collaboration across different supports, such as web-based online collaboration tools.
