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

HORRIBLE MUSIC....

キャプテンの立ち振る舞いがかっこいい😳

相変わらずかっこ悪い船だ。 底引き船かな🤣

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KZbin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

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?

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.

Early Hamilton jet boats had gate steer back in the 60s

And the last

What purpose is this serving??? Actual question not smug.

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 ........

It good to have gate rudder fitted in a certain ships .it helps at lot short maneuver and improve the vessel turning radius , but their are new propulsion unit now a days using " z- piller " that not only for ships but for oil rig flatform just to maintain thier position on site especially during rough seas
