IRIS is a dynamic e-learning tool which combines traditional interactive presentation and computer-based-training technologies with situational and equipment simulation features, enabling maritime incidents to be recreated as immersive learning exercises in a unified and straightforward platform. It is a software system specifically designed around the requirements of maritime safety training incorporating a powerful scripted computer based training architecture as well as adapted versions of our well established DNV Class A certified simulation systems. The software has been designed to be compatible with a broad range of WINDOWS based computers, including the training systems typically found on-board vessels. IRIS users can choose from a large and growing library of learning modules covering a wide variety of incident themes and offering a virtually unlimited set of learning opportunities. Custom built modules including powerful feedback features can also be created to suit specific requirements.
