Shipyard Kooiman is currently performing sea trials with their latest build, a patrol vessel for the Port of Rotterdam. ErgoS contributed to the design of this ship, including a 3D field-of-vision study, wheelhouse design, navigation and command workplaces, camera plans and interior design. The result is a very innovative vessel, in both technical and ergonomical terms. For instance: the workplace is designed as a freestanding ‘island’. Consoles and controls are placed aside, instead of in front of the officer. As a result, the user does not have to operate his rail chair to stand up. We achieved an excellent field-of-vision, and changing working positions is much easier and more natural, compared to a traditional desktop arrangement.
