THE FUTURE

Hybrid Power Gen “Signi? cant growth in hybrid electric ships should be expected after 2020 in ship segments like harbor tugs, offshore service vessels, and ferries. By 2025, a large share of new commercial ships will probably include some degree of hybrid- ization. In addition to fuel consumption bene? ts, hybridization offers power redun- dancy, reduction in noise and vibrations, and a decrease in pollutant emissions such as NOx, SOx and particulate matter.” – Christos Chryssakis,

DNV GL: A Vision of the Future

Knut Ørbeck-Nilssen, CEO, Maritime, DNV GL, outlines his vision of how the shipping industry will change over the next 10 years: “In my vision of the future for shipping I see an industry that is still at the heart of global trade, bringing people together, and keeping the world’s economy vital and growing. But the industry itself, the vessels, the infrastructure, and the systems that connect them could change substantially. The biggest change will be the way ships are powered. The world’s modern ? eet will rely on a broader range of fuels and propulsion solutions. On the long-haul trades, we could see a move toward dual-fuel engines, or pure gas fuelled, as well as other gases like ethane, and newly developed renewable biofuels becom- ing a part of the mix.

“The use of batteries to complement main engines will also grow, to smooth power delivery, drive auxiliary systems, and maximize engine ef? ciency. In some sectors, such as ferries and coastal vessels, the trend could even be toward vessels pow- ered completely or largely by electricity. Connectivity between ship and shore will have vastly improved and will be much more common. The ? eet of the future will be continually communicating with its managers and perhaps even with a ‘traf? c control’ system that is continually monitoring vessel positions, maneuvers and speeds.

“Fleet managers will be able to analyze these data, enabling them to advise the captain and crew on navigation, weather pat- terns, fuel consumption, and port arrival. This will help to reduce the risks of human error leading to accidents, increase cost ef? ciency, and help to improve environmental performance. Some of these data will also be shared. Ports will use the data to help them plan and optimize loading and unloading. Classi? cation societies will analyze the data to check on the status of machinery and hull, letting the owners and operators know when a survey is required based on the condition of the systems, helping them to reduce downtime and avoid unnecessary maintenance.

“At DNV GL we are excited to be a part of this coming transformation. We will continue to work with stakeholders across the maritime world to realize the potential of our industry and make sure that the outlook for shipping tomorrow is brighter than today.” 72 Maritime Reporter & Engineering News • AUGUST 2016
