New digital solution could reduce shipping emissions by 15 per cent


A new digital solution could reduce emissions by 15 per cent by optimsing vessel arrival speeds.

The Blue Visby solution can reduce shipping emissions by around 15 per cent by eradicating the practice of ‘Sail Fast, then Wait’ (SFTW) supported by digital technologies.

The solution eliminates the prospect of ships sailing at speed across oceans only to wait at anchorage outside ports – reducing emissions for maritime journeys by 15 per cent on average.

If applied globally, the solution has the potential to reduce the carbon footprint of the global shipping fleet by more than 60 million tonnes of CO2 per year – which is larger than the total emissions of an entire country like Norway.

Taking into consideration parameters such as the performance and characteristics of each vessel, port congestion at destination, and weather conditions, the Blue Visby algorithm provides an optimal target arrival time for each vessel, while keeping their order of arrival as if they had sailed independently without the solution.

This enables vessels to slow down, cutting their fuel consumption and emissions, but still keep their place in the queue and arrive one after the other, which reduces unnecessary waiting times outside ports.

The Blue Visby Solution includes a contractual framework that introduces a sharing mechanism that enables stakeholders on each voyage (shipowners, charterers and cargo interests) to share the costs and benefits of the implementation of the Blue Visby Solution, including fuel savings, the costs of a lengthier journey, and the financial value of emissions reductions where applicable.

This contractual architecture is designed to be compatible with the standard terms of maritime contracts and does not require any new legislation or regulations.

The Blue Visby Consortium presently includes NAPA, Stephenson Harwood LLP, and 11 other maritime leaders from the shipping industry, government, classification societies, consultancies, financing, and environmental organisations: Anglo-American, Carbon Trust, ClassNK, CMB, Drewry, Ocean Conservancy, Lloyd’s, the UK Hydrographic Office, the University of Manchester, Tankers International, and Vertis.
