Manufacturer: IMC Co., Ltd.
Product: Surf-bulb Energy Saving Devices

Features

① By adopting SB, it is possible to reduce power by 3-7% at the same ship speed. ②
It has been adopted on over 800 ships.
③ It can be easily installed on existing ships as well as newly built ships.
④ The adoption of SB does not change the steering characteristics, so maneuverability remains the same.
⑤ As the SB is located behind the propeller, even if the SB is damaged, it will not lead to damage to the propeller. Of course, there has been no damage to the SB so far.
⑥ It is inexpensive, so the investment can be recovered in a short period of time.
⑦ The adoption of SB reduces vibration directly above the propeller.

SURF-BULB , an energy-saving device behind the propeller, achieves energy savings of 3% or more.

Principle

① Convert the rotating flow behind the propeller into forward thrust.
② Prevent the generation of propeller hub vortexes.
③ Improve propeller efficiency by generating wake gain.
