Analisa Performa Bow Thruster Antara Penggerak Hidrolik Dengan Penggerak Elektrik

Jurnal Sains & Teknologi Fakultas Teknik Universitas Darma Persada, 2022
Bow Thruster adalah alat yang digunakan untuk membantu manuver di kapal. Bow Thuruster biasanya digunakan pada kapal – kapal yang berlayar pada daerah yang membutuhkan manuver yang cukup sulit. Pada penelitian kali ini penulis akan membahas mengenai perancangan bow thruster pada kapal Supply vessel 279 DWT.

Noise Reduction of Bow Thrusters

1986
On many types of ships the operation of a bow thruster can be most annoying for the crew. The reason is that a thruster is a very strong acoustical source which induces intermittent noise in the adjoining accommodation spaces. Further, a bow thruster is located in an area of the ship where there generaly are no other major noise sources.

Electromagnetic Field Measurements of Bow Thruster Drive With Frequency Converter

2007 Compatibility in Power Electronics, 2007
The results of electromagnetic field measurements of bow thruster drive with frequency converter, made during stay of the vessel in the port, are performed in this paper. These experiments are the one of the steps of the bigger research project, which leads to evaluation of electromagnetic field intensity onboard research-training vessel m/v "Horyzont ...

The effectiveness of a bow thruster at low and medium ship speeds

International Shipbuilding Progress, 1967
The manoeuvreability of a ship is poor at low speed, but it can be improved considerably by installing a bow thruster. The model tests which KMW have carried out at HyA show that the thrust from the bow thruster jet does not change with speed. However, the pressure distribution on the hull is changed by the jet so that the resulting side force and ...

Thruster-Interaction Effects on a DP Shuttle Tanker - Wake Flow Measurements of the Main Propeller and Bow Tunnel Thrusters

Volume 1B: Offshore Technology, 2014
This paper discusses thruster interaction effects for a DP shuttle tanker, equipped with two main propellers and rudders, as well as two bow tunnel thrusters. Thruster-interaction model tests were carried out in MARIN’s Deepwater Towing Tank. Detailed PIV measurements were taken of the wake flow behind the main propellers and rudders.

The Performance of a Tunnel Bow Thruster With Slow Speed Ahead: A Revisited Issue

Journal of Navigation, 2009
This paper studies the effectiveness of a ship's tunnel bow thruster with slow speed ahead. After describing the general reasons for the decrease of performance with slow speed ahead, the Anti Suction Tunnel (AST) is analyzed as an advisable state-of-the art design option that aims to improve performance.

Observations on the Effect of Vessel Speed on Bow Thruster Performance

Marine Technology and SNAME News, 1971
The paper explores the effect of vessel speed on thruster performance by comparing fullscale data to model test data. The steering effect of the thruster alone, and in combination with the rudder, is considered. A limited amount of full-scale data on the steering effect of a bow thruster, with the vessel proceeding astern, is presented.

Electric Hybridization of a Bow Thruster for River Boat Application

2015 IEEE Transportation Electrification Conference and Expo (ITEC), 2015
The paper deals with the electric hybridization of a bow thruster for a river tugboat application. The knowledge gap leads to the full electrical retrofit of a previously high power hydraulic bow thruster system, in the objective of having more electrified subsystems in the boat, leading to an eco-friendly solution.

Optimization of Bow Thruster Openings for Improved Hydrodynamic Performance

Volume 6: Polar and Arctic Sciences and Technology; CFD, FSI, and AI
Abstract Bow thrusters are a common feature of ships nowadays and come with the undesired effect of creating relatively large openings at the bow of the ship, increasing the resistance of the hull. The most common solution for mitigating the increase in hull resistance, and at the same time protecting the thruster from ingestion of large
