Gate Rudder Ship Erge voyage data provided by CETENA
The leader of WP2 (CETENA) has submitted their voyage data analysis of Erge to EU.
Gaters installed the gate rudder on Erge by replacing the flap ruuder last year ( April 2023).
The sea trials before and after showed remarkable fuel savings 35% by this retrofit.
After delivery of Erge equiped with gate rudder, WP2 has collected the perfomrnace data and reported to EU authority in March 2024.
This video will introduce this valuable data by which the performance of Erge after delivery can be evaluated.

ゲートラダー船「のがみ」と海の男たち(関門海峡)
Переглядів 43 тис.Рік тому
ゲートラダーを搭載したコンテナ船「のがみ」、内航船としては国内最大クラスです。本船の操船性を確認するため乗船させていただきました。ここでは関門海峡通過時の本船の針路安定性を確認しています。 なお、川下りにおける急流の速度は6ノット程度と言われており、この日の「のがみ」は、ほぼその急流を昇っていることになる。
ゲートラダー関門操船シナリオ(追突回避)
Переглядів 237Рік тому
ゲートラダーの加速性の良さ、操舵しても船速低下が小さい事に気づかされます。また、馬力計がゼロとなり、スリップ100%の状態でも、船の方位が維持できていることから、舵が効いている様子がうかがえます。なぜなら、舵効きを失うと、船は大きなドリフト(横滑りと回転)を始めるからで、船首方位と船の針路が一致している場合は、舵が効いていると見なせます。 本船には、この後、前方の船との距離を十分に取って航路に入るよう指示がでています。

The turning ability and the course keeping ability is conflicting design target. The designer need to pay attention to the difference between the sea trial conditions and actual ship operation conditions. The designer should not demonstrate the best performance at the sea trial condition if the condition is far from the operation conditions. From the sea trial data and full scale experiments af...

Very clever solution for conventionally propelled vessels (as opposed to a complete Z-drive refit)!

Nice video!!
はじめまして コメントにて失礼致します。 父、浅海宣博に素敵なメッセージをありがとうございました。 亡くなってからもう3年経ちました。 今日偶然にも見つけたUA-camでした。 胸が一杯になりました。 仏前の前で見せてあげたいと思います。 父も喜ぶはずです。 ご厚情深く感謝致します。 ほんとうにありがとうございました。
Thanks for the interesting video.
素敵で購読しました!
美しい映像ありがとうございます♪
若いCPやなー
5:31 左の図が、まるでダクテッドファンの断面図のように見えた。ダクテッドファンのナセルが推進力を生むのと同じような仕組みなのかな。 6:15 そのまま「ゲートラダーは、ダクトプロペラの機能を持つ新しい舵です」と説明があって、疑問は解決。
Will an English version of this presentation be available soon?
キレイだね、なかなか高尚なp趣味だ
What is the % difference between the two kind of rudders?
superb
Thanks for information
In the Roman Empire days, the Romans would have been real proud of this technology. No more slave oar men.
Sounds like a locomotive.
Is the propeller floating?
padang kota ook laa. b .n a .c .i rab
well, it's look like so useful for large ship ! especial the stopping mode ! more safe for emergency may crash happen !
I am a harbour pilot in Brazil and I have a couple of questions: 1. What does the steering controls at the bridge look like? 2. Are there any changes in the rudder orders as compared to the standard rudder? Thanks!
Owing to the excellent fuel comsumption of Shigenobu, the ship owner decided to build 2nd gate rudder vessel which is larger than the original ship. Addition to this new vessel, another two coastal vessels will be build early next year. We will introduce their sea trial results again.
A model test of Shigenobu with a Gate Rudder was conducted at Istanbul Technical University (ITU) using 5m wooden model.
Has it ever been installed together with a Kort nozzle?, with what results?
Patent out-flank maneuver and rip-off of Kitchen rudder
From "Motor Ship" 2nd May 2019 --- Analysis of voyage data for the world’s first vessel fitted with a Gate Rudder reveal fuel savings of up to 30 percent compared with a sister vessel. The world’s first gate rudder system was fitted to the container ship Shigenobu, which entered service in 2018. The voyage data from the vessel’s first nine months of service reveal that this recently patented system could provide energy savings of as much as 30%, compared with the voyage data of an identical container ship Sakura, fitted with a flap rudder. The results suggest the innovative Gate Rudder arrangement holds significant potential to replace the conventional propeller-rudder systems to achieve a step change in EEDI compliance.
Wouldn’t it be easier to use an azipod?
New tech or not as long as it works and could save more fuel/energy it's an improvement to the conventional system. I appreciate people who works on this project, well done!
I don't think many people understand that the advantage of this over vector thrust units or z-piller thrusters is that it is a way of retrofitting older ships far more cheaply and easily. The technology isn't as advanced as other methods but it doesn't need to be.
Seems like a failure from the start
Sorry but did you watch the video??
@@Arthur-ej5gi - The failure start to failure finish. Too many parts, to many things to go wrong, just a complete waste of money.
@@mynameisray I think this could be a great idea, let's wait untill further tests have been published before calling a complete waste of money
@@Arthur-ej5gi - He's just a blowhard know nothing.
This music has me totally hyped up for it , man!
The new video clip of the gate rudder " Gate Rudder after delivery" will be uploaded soon. It will introduce the performance of the gate rudder after delivery. The bow thruster is very important for a coastal vessel because they need to berth without support of tug boats. Generally speaking, the combination of a bow thruster and a special high lift rudder is a standard like a sister ship Sakura. In order to obtain the large turning moment, the bow thruster will be installed on the bow part as far as possible from the mid ship. In order to control two dimensional ship motions (surge, sway and yaw), we need two thrusters at least.
SHE STILL HAS A BOW THRUSTER TO HELP TURN HER WHY CAN'T IT BE DONE WITHOUT THE TRUSTER FORWARD?..
Seems brilliant. In addition also appear to be adaptable to existing vessels without major works.
I wonder if it is mounted in warships.....I guess it is not
what is crabbing mode for?
Jiashun Gou, I think side-to-side maneuvers.
Berthing, tight turns in canals?
full reverse looks like it would rip the rudders off if going full speed. they look a little flimsy
That is the coolest thing!! I wonder if that system is available for smaller vessels? Thanks for sharing!
Fantastic..! Amazing innovation setting standards to efficient manoeuvring!
My sense is that it may need bottom support on larger vessels. This would assist with bearing surface life. It still should be less expensive than azipods.
That was my first thought as well!
Early Hamilton jet boats had gate steer back in the 60s
And the last
What purpose is this serving??? Actual question not smug.
It helps the water flow better around the prop, and can provide more effective side thrust for increased manueverability. try that with a conventional rudder, and after a certain angle it will lose effectiveness. so better for maneuvering, while retaining the low drag profile of conventional rudders. best of both worlds, and relatively simple, as it's just one more shaft. that's how I understand it anyhow.
FPVREVIEWS cool I used to work on tugs not to long ago when everybody was going crazy over tractor tugs then I guess I missed this one Thank you for the information. God bless
In addition to the other points already made by others, I would imagine significantly less drag since the water column from the prop is not directly striking the rudder, like with stern rudders. Also, the thinner cross section in parallel probably generates better laminar flow and less vortices, thus reducing drag and increasing fuel efficiency. I'm not an engineer but those are my guesses.
dyno!
Very interesting, first I have seen this design. I hope it works.
What about a korts nosal a tube around the proppeler???
Ahhhhh - white text on a cloud background is a poor choice ........
