Organization's Description:

GRi Simulations Inc. is a Canadian company focused on real-time simulation, modeling and visualization of critical marine activities to support increased process efficiency and operational safety.

Founded in 1986, GRi’s initial focus was on development in the area of bathymetric surveying using semi-submersible platforms.   In 1997, GRi began development on the Virtual Remotely Operated Vehicle (VROV) Simulator System, an instructional platform for the training of ROV pilots with unparalleled dynamic realism.  With this advance, GRi began its focus on computer modeling and the simulation of subsea operations.

In subsequent years, GRi has been characterized by its ability to innovate based upon the unique challenges and opportunities of its clients. Such innovation has allowed VROV to maintain its status as an industry-leading ROV pilot training tool while adding dimensions of situational testing and mission rehearsal to VROV’s utility. With the introduction of IDEA-FDK, GRi has enabled VROV simulations and high-fidelity engineering analysis tools to facilitate field layout design, promoting the environmental and operational objectives of oil and gas projects.


Launch and Recovery Systems (LARS) are an essential component of safe and efficient ROV operations, often playing a vital role in harsh marine environments. In recognition of the challenging and vital functions of these systems, GRi has developed a LARS simulator which uses advanced sea-state physics, vessel RAO data, and real-world controls for a highly authentic simulation experience.
