GRI Simulations Inc. (formerly Geo-Resources Inc.) is a Canadian company established in 1986 to provide ocean mapping services for domestic and international customers using the DOLPHIN semi-submersible Remotely Operated platform.

In 1997, GRI built on this experience to focus on supporting sub?sea Remotely Operated Vehicle (ROV) operations by providing simulation technology to enhance ROV pilot training, mission planning and rehearsal for offshore oil construction and production operations and Military SAR and Mine Countermeasures activities.

As well, design of sub?sea systems (including ROV vehicle and tooling) design is facilitated through the application of this technology in prototype design, and iterative testing for performance and ROV accessibility.
