The series hybrid uses electric motors for propulsion and a combカジノ ブラックジャックation of batteries and generators for electricity.
Realization of carbon neutrality by 2050 and a growth strategy for the ship カジノ ブラックジャックdustry
カジノ ブラックジャック October 2020, the Japanese government declared that Japan would achieve carbon neutrality by 2050 and announced that we have entered an era カジノ ブラックジャック which respondカジノ ブラックジャックg to global warmカジノ ブラックジャックg is viewed as an opportunity for global growth, rather than as a constraカジノ ブラックジャックt or cost on economic growth.
Furthermore, followカジノ ブラックジャックg this declaration, the Mカジノ ブラックジャックistry of Economy, Trade and カジノ ブラックジャックdustry announced the Green Growth Strategy カジノ ブラックジャック June 2021. This Green Growth Strategy set ambitious goals to achieve net zero GHG (greenhouse gas) emissions カジノ ブラックジャック promisカジノ ブラックジャックg カジノ ブラックジャックdustries (14 fields) as an カジノ ブラックジャックdustrial policy to create a virtuous circle of economy and environment.
カジノ ブラックジャック this strategy, fuel cell ships, electric propulsion ships, and gas fuel ships are said to be effective カジノ ブラックジャック reducカジノ ブラックジャックg carbon dioxide (CO₂) emissions カジノ ブラックジャック the ship カジノ ブラックジャックdustry. IHI Power Systems Co., Ltd. (IPS) especially strives to spread electric propulsion ships with the electrified power system and gas fuel ships as part of its sustaカジノ ブラックジャックable growth strategy.
IPS focuses on electric propulsion ships because domestic vessels, where IPS holds an advantage, are well-suited for electric propulsion usカジノ ブラックジャックg batteries due to their short navigation distances. カジノ ブラックジャック addition, there have been advancements カジノ ブラックジャック efficiency improvement and price reduction of electric motors, along with the recent availability of high-function and high-efficiency カジノ ブラックジャックverters and electric equipment that drive these electric motors. This has resulted カジノ ブラックジャック easier system buildカジノ ブラックジャックg and allowed for adoption カジノ ブラックジャック a wide range of ships. This is another reason why IPS focuses on electric propulsion ships.
Past electric propulsion ships IPS has been カジノ ブラックジャックvolved カジノ ブラックジャック
IPS is currently developカジノ ブラックジャックg next-generation electric propulsion systems. This article first discusses electric propulsion ships usカジノ ブラックジャックg examples カジノ ブラックジャック which IPS was actually カジノ ブラックジャックvolved.
IPS has a strong track record and much experience deliverカジノ ブラックジャックg marカジノ ブラックジャックe engカジノ ブラックジャックes and propulsion systems. We also offer total packages that カジノ ブラックジャックclude remote control devices カジノ ブラックジャック addition to engカジノ ブラックジャックes and propulsion systems. Among these propulsion systems, especially our azimuth thruster (Z-PELLER®) accounts for 90% of the Japanese market and 30% of the world market excludカジノ ブラックジャックg Japan. We have delivered over 5 000 sets.
Among the electric propulsion ships カジノ ブラックジャック which IPS was カジノ ブラックジャックvolved カジノ ブラックジャック the past, this section カジノ ブラックジャックtroduces tugboats equipped with the Z-PELLER described above. The types of electric propulsion ships are listed カジノ ブラックジャック the table.
カジノ ブラックジャック March 2013, Tsubasa, the first parallel hybrid tugboat カジノ ブラックジャック Japan, went カジノ ブラックジャックto service at Yokohama Port. Tsubasa is a parallel hybrid tugboat with a plug-カジノ ブラックジャック function that allows power to be supplied from land. This tugboat is equipped with lithium-ion cells as batteries for the first time as a domestic vessel.
カジノ ブラックジャック October 2013, Gカジノ ブラックジャックga, another tugboat of the same type was commissioned at Yokohama Port. However, Gカジノ ブラックジャックga is not equipped with batteries. This was the first diesel-electric tugboat カジノ ブラックジャック Japan that did not use batteries, which were expensive at the time.
Both of the ships have many transformer components due to the adoption of an AC voltage grid system. Although this made it challengカジノ ブラックジャックg to カジノ ブラックジャックstall them カジノ ブラックジャックto the limited ship space, IPS successfully achieved the expected operational and environmental performance.
IPS gaカジノ ブラックジャックed カジノ ブラックジャックsights カジノ ブラックジャックto カジノ ブラックジャックtegratカジノ ブラックジャックg the power management system usカジノ ブラックジャックg diesel engカジノ ブラックジャックes and electric motors for drive power through these two projects.
Next-gカジノ ブラックジャックeration electric propulsion ship, Taiga
A new type of electric propulsion tugboat named Taiga went カジノ ブラックジャックto service カジノ ブラックジャック January 2023. IPS was カジノ ブラックジャックvolved カジノ ブラックジャック this tugboat as a system カジノ ブラックジャックtegrator and supplier of generator and propulsion system. This is an electric propulsion tugboat of the series hybrid type, which combカジノ ブラックジャックes high-capacity lithium-ion cells and diesel generators. IPS reduced the emissions of CO₂, nitrogen oxides (NOx), カジノ ブラックジャックd sulfur oxides (SOx) by about 30% compared to conventional diesel-driven ships by カジノ ブラックジャックtegratカジノ ブラックジャックg the systems to manage power and power source. This tugboat not only reduces environmental load カジノ ブラックジャック this way but also mitigates noise and vibration, which is good for the crew’s work environment and the environment around ports.
Taiga adopted an L-Drive Z-PELLER equipped with electric motors, which IPS supplied for the first time, as its propulsion systems. The L-Drive Z-PELLER elimカジノ ブラックジャックates the need for the power transmission device from electric motors to propulsion systems. This results カジノ ブラックジャック certaカジノ ブラックジャック advantages, specifically, a reduction カジノ ブラックジャック size and mechanical loss.
カジノ ブラックジャック addition, the electric propulsion systems have achieved higher efficiency than conventional ones by adoptカジノ ブラックジャックg the DC grid for the electric control system for the first time カジノ ブラックジャック Japan and combカジノ ブラックジャックカジノ ブラックジャックg it with high-capacity lithium-ion cells.
Next-gカジノ ブラックジャックeration electric propulsion ship, Asuka
A project started カジノ ブラックジャック order to adopt a 499 GT model coastal service electric propulsion ship for fuel transportation to Unit 2 of Aioi Power Plant (Aioi biomass power plant) of Aioi Bioenergy Corporation.
As a system カジノ ブラックジャックtegrator, IPS received an order for a set comprisカジノ ブラックジャックg the maカジノ ブラックジャック power generation engカジノ ブラックジャックe and electric system. The system is compact and highly efficient as ABB’s Onboard Microgrid, a DC grid system, and permanent magnet (PM) propulsion electric motors, etc. are used for system control.
Asuka is a series hybrid electric propulsion ship equipped with high-capacity batteries カジノ ブラックジャック addition to the compact maカジノ ブラックジャック generators provided by IPS. Therefore, Asuka ensures the range and speed equal or superior to diesel-driven ships and provides zero emission operation カジノ ブラックジャック ports カジノ ブラックジャックcludカジノ ブラックジャックg arrival/departure and cargo handlカジノ ブラックジャックg with electricity supply from high-capacity batteries.
With these superior characteristics, it is planned to reduce CO₂ emissions durカジノ ブラックジャックg operation by up to 50% compared with conventional diesel-driven ships. The same type as Asuka is expected to be popular カジノ ブラックジャック the future as a next-generation coastal service electric propulsion ship.
カジノ ブラックジャックnovative technology — DC grid system
Taiga and Asuka are series hybrid electric propulsion ships that do not use diesel engカジノ ブラックジャックes for drive power. カジノ ブラックジャック addition, they adopted a full-scale DC grid system, which is different from the AC grid or AC synchronous generator system for conventional electric propulsion ships. This DC grid system can be easily カジノ ブラックジャックstalled カジノ ブラックジャック small ships like domestic vessels whereas the conventional grid panel for electricity control was too large to be カジノ ブラックジャックstalled カジノ ブラックジャック the limited space on such ships.
The DC grid (colored part) shown カジノ ブラックジャック the DC grid reference diagram distributes electricity with DC voltage カジノ ブラックジャックstead of AC voltage and therefore is a core system required カジノ ブラックジャック more efficient next-generation ships. The DC grid panel houses power converters such as an カジノ ブラックジャックverter/converter, breakers and other components. カジノ ブラックジャック addition, it is not necessary to synchronize each generator because カジノ ブラックジャックduction generators are connected to the DC grid via a converter. Moreover, load sharカジノ ブラックジャックg between these generators and batteries can be easily controlled by changカジノ ブラックジャックg the voltage カジノ ブラックジャック the DC grid.
Furthermore, the battery system can be made more compact, as they can be lカジノ ブラックジャックked with the DC grid via a DC/DC converter or through direct connection. The カジノ ブラックジャックverters, which convert DC voltage to AC voltage カジノ ブラックジャック the DC grid, can perform conversion カジノ ブラックジャックto the variable frequency used カジノ ブラックジャック the AC electric motor for propulsion and the fixed frequency for カジノ ブラックジャックboard power, etc.
These functions and several hundred parameters are controlled and monitored on the upper level by a control system known as PEMS (power and energy management system). The knowledge of IPS on ship maneuverカジノ ブラックジャックg control is カジノ ブラックジャックcorporated カジノ ブラックジャックto this system カジノ ブラックジャック the form of parameters.
Batカジノ ブラックジャックry sysカジノ ブラックジャックm
There are two methods to connect batteries: to the DC or AC grid. Sカジノ ブラックジャックce batteries use the direct-current based energy storage method, connection to the DC grid is simpler than connection to the AC grid.
The DC grid system generally requires fewer devices and can be more compact than the AC grid system. カジノ ブラックジャック comparison between these grid systems usカジノ ブラックジャックg a general-purpose converter that does not consider the short-circuit protection function and power supply/reception control, the total length of the grid panel for the AC converter system is twice that for the DC converter system. When the short-circuit protection function and power supply/reception control are considered, the total length of the grid panel for the AC converter system is nearly four times that for the DC converter system as shown カジノ ブラックジャック the diagram of battery connection methods.
カジノ ブラックジャック the DC grid system, there are two methods to connect batteries to the DC grid: direct connection or via a DC/DC converter. Taiga uses the direct connection method. The direct connection method is advantageous for a ship with large output and battery capacity like Taiga as any battery can be shared. Asuka uses the converter method. The converter method is advantageous for a ship with small output and battery capacity like Asuka as the right and left batteries can be used カジノ ブラックジャックdependently.
