Recently，Danfoss, the world's leading provider of energy efficiency solutions, together with Cummins, the pioneer of global power technology, won the first batch of hybrid high-speed catamaran ferry projects in Hong Kong launched by the Hong Kong SAR Government of China in 2021.。The project is Danfoss China.EditronShip team wins the first order for ship DC networking system in Hong Kong, China，Take the lead for Danfoss to continue to expand the Hong Kong market，It will also have a demonstration effect on the green transformation of the ferry industry in Hong Kong.。
The project consists of two 450-passenger hybrid high-speed catamaran ferries.，The total length is 40 meters，Design speed 23 knots，Rated for 450 passengers，Parallel hybrid DC networking system is adopted.。The two ferries will be built by Cheoy Lee Shipyard Limited, a famous shipyard in Hong Kong.，The main equipment of the whole ship's power system consists of two CumminsQSK50 host、Two DanfossEditronPermanent Magnet Synchronous Motor、Total of four groups 311.2kW·hA power battery and multiple frequency converters.。To meet emission requirement，CumminsQSK50 main engine adopts advanced full electronic control high pressure common rail fuel system.，And equipped to meet the International Maritime Organization（IMO）Selective Catalytic Reduction for Stage III Emission Regulation（SCR）System。
DanfossEditronThe permanent magnet synchronous motor can realize power generation according to different operation areas on the route.、Switching between two electric operation modes。AtNon-emission controlled areasDuring the voyage，The vessel is driven by the main engine，At the same time, it drives the motor to generate electric energy to charge the battery and supply the daily load.。And inEmission control area，Batteries as the energy source for the whole ship，The motor drives the ship to move to realize zero emission。When berthing for a long time at a terminal equipped with charging piles，This configuration can also meet the requirement of charging the battery pack from the shore power.。
The system scheme can realize flexible ship electric drive mode.，While meeting the emission requirements in Hong Kong，But also reduce fuel consumption.，Reduce ship equipment maintenance cost，Remarkable economic and social benefits。
Electrification is one of the most effective solutions to reduce carbon emissions in the shipbuilding industry.，For Hong Kong, China、The Yangtze River、Visitors from the Pearl River Basin、Energy saving and emission reduction in the freight transport industry is of great significance.。Danfoss is the world's leading provider of energy efficiency solutions，PossessEditronAnd a series of transportation electrification solutions.。We will work with our partners to promote the application of green solutions in the transportation system.，Promote the green transformation of the industry and achieve the goal of double carbon.。
——Xu Yang
President of Danfoss China
Transport emissions account for 27% of total global energy-related carbon emissions%。And look around the world，Ferry industry transport 47 per annum.700 million passengers and 3.7.3 billion Vehicles，It is an important emission source.。And ferries often sail around the city.，Exacerbating the already serious air pollution。Electrification is a clear and easy way to reduce emissions in the maritime industry。Solutions include both new electric ferries，It also includes the electrification of existing ferries，Thus reducing the number of lakes around the world、Carbon emissions in cities and Straits。
The waterway is the traffic on the island of Hong Kong and from Hong Kong to Macao.、An important part of mainland transportation；Ferries are the most important means of transportation in Hong Kong's waterways.，The annual passenger flow of Hong Kong ferries can reach 1,8 million people。Although the ferry industry in Hong Kong is very developed,，But the ship is very old.，And that change is slow。According to statistics，The average age of nearly 200 ferries of all 12 ferry companies in Hong Kong has exceeded 20 years.，The oldest ferry is 66 years old.。High pollution、High emissions、High fuel consumption and high maintenance costs have become urgent problems for the ferry industry in Hong Kong.。
Xu Yang said：“Through this project，Danfoss wants to work with partners，Jointly open a new era of green ferry in Hong Kong。”
DanfossEDITRON
In that field of ship DC networ system，DanfossEDITRONHas been a leader in the industry。It has nearly 100 sets of achievements in the world.，And created a number of industry world records.。EDITRONEfficient、Lightweight DC network electric drive system is composed of core motor electronic control equipment, permanent magnet motor and modular frequency converter independently developed by Danfoss.ECSComposition of control system，Can provide customers with series hybrid、Parallel hybrid、All-electric and other rich modes。
