GREENWAVE - PASS - Performance Analysis Software System

Greenwave’s remit is to reduce the environmental impact of shipping by finding ways that individually and collectively reduce fuel consumption significantly and thus reduce emissions.

Identifying solutions, then developing and refining them into usable products is Greenwave’s first objective.

The next step is to encourage the industry to adopt these fuel saving technologies and to use them effectively and the consequent reduction in emissions.

The PASS Programme provides the tools that will first demonstrate to ship owners the quantity and value of the fuel savings they are able to make with Greenwave technologies when applied to their own ships.

Our PASS web-hosted software will enable a ship owner or operator, anywhere in the world, to enter data about one of their vessels (dimensions, displacement, engine size, and features such as cranes, superstructure etc). When this information is cross referenced with data about route, distance, expected wind and tide conditions it will display the predicted fuel consumption.

Any combination of Greenwave’s solutions can then be applied to see immediately the effect in both tonnes of fuel and emissions saved.

Once at sea, the ship’s Master needs to be able to monitor what each of the fuel saving applications is actually doing so that he can adjust both the applications and the ship’s engines for optimum effect. For example:

The operating angles of the aerodynamic improvement kit could be modified according to wind speeds and direction.

Similarly, the speed and rotational direction of the wind engines can be adjusted.

Hydrodynamic applications such as bubble bearings can be enhanced or decreased in line with prevailing sea conditions.

These onboard visual display systems will give the Master a simple to use rolling live report on performance and provide detailed feedback that will enable him to adjust engine power for optimum efficiency. The data could also be integrated into the ship’s log.

Most significantly, the PASS software system will serve as a constant reminder of the ship’s lower fuel consumption, lower emissions and thus its reduced impact on the environment.
