Side Thruster

Product catalog summary
Overview
The document outlines technical specifications and installation guidelines for side thrusters used in marine vessels to enhance lateral movement and maneuverability, particularly during berthing.
Specifications
Side thrusters can be installed on the bow, stern, or both, with models including DH300/300C, DH330/300C, DH395/300C, DH400/400S, and DH500/400S. Each model has specific requirements for thrust force, input power, rated flow, and pressure.
Installation Guidelines
  • Thrust Calculation: Examples are provided for calculating thrust based on leverage and torque.
  • Installation Depth: Recommended tunnel depth is between 1/2 to 4/4 times the tunnel diameter below the waterline.
  • Tunnel Length and Ends: Optimal tunnel length is 2-4 times the inner diameter, with rounded ends to enhance thrust and reduce noise.
  • Preventing Drag: Suggested installation shapes help minimize speed loss due to water flow impact.
Model Selection and Maintenance
The document includes a guide for selecting models and maintenance instructions, highlighting the importance of maintaining oil levels, cleanliness, and checking for obstructions.
System Components
The side thruster system comprises tunnels, valves, drain filters, and controllers, with part numbers and configurations provided.
Control Panels
Details on various control panel configurations are provided, including single and twin panels for different valve systems.
Pump and PTO Specifications
Specifications for hydraulic vane and piston pumps include capacity, pressure, and part numbers, along with tables for pump size and attachment plate selection.
Key Recommendations
  • Ensure proper installation depth and tunnel length for optimal performance.
  • Regular maintenance is essential to prevent damage and ensure efficient operation.
  • Select appropriate models and components based on vessel specifications and operational needs.
Additional Specifications
  • DPO087: Features two output shafts for independent clutch operation, with a maximum input RPM of 3000 and a dry weight of 3000 kg.
  • DPO167: Similar to DPO087, supports direct hydraulic pump connection, expandable to 3-4 outputs, with a maximum input RPM of 3000 and a dry weight of 1981 to 3000 kg.
  • DHD500/400SRR Stern Type Thruster: Offers high turning force and easy maintenance, requiring 122 HP and operating at a rated flow of 169.2 ℓ/min with a rated pressure of 400 ㎏/㎠.
Procedures and Components
The stern type thruster package includes a power pack, proportional valve, drain filter, and controller, with external installation to reduce maintenance costs and enhance durability. Users should refer to the user manual for detailed circuit diagrams.
Recommendations
  • Use the stern type thruster for improved ship maneuverability and efficiency.
  • Consider the DPO167 model for applications requiring multiple outputs and higher input capacities.

Installation 1. Thrust calculation based on the center of turning center of turning Example : A: 100kg thrust x 11m leverage = 1100kgm torque to rotate the boat B: 100kg thrust x 10m leverage = 1000kgm torque to rotate the boat In position A you will get 10% more thrust to turn the boat around. 2. Recommended installation depth Generally the top of the tunnel should be a minimum of 1/2 x the tunnel diameter below the waterline. [A] This is an absolute minimum and we recommend that it is at least 3/4 x tunnel diameter below the waterline. [B] A really good distance is about 4/4 x tunnel diameter...

Installation For the vessels with light weight and low draft, it can be difficult to install a thruster at a location that satisfies the three installation depth conditions. In this case, the tunnel can be installed inclined as shown in the figure below. Standard installation Inclined installation 3. Installation tunnel length 1) If you want to get the optimal thrust, 2~4 times the inner diameter of the tunnel is most suitable, and if it exceeds 6 times, thrust may be reduced. 2) If the tunnel is too long, the frictional resistance increases, which reduces thrust. If the tunnel is too short,...

Installation 5. Prevent drag from tunnel It is recommended to install the tunnel in the shape as shown in the figure below to reduce the decrease in ship speed due to the impact of the water flow on the tunnel during vessel operation. Fig.2 When the installation space is narrow on the hull. 6. Single side thruster (DH400, 500) installation instructions Single propeller side thrusters (DH500, DH400) can be installed in two ways depending on the size of the hull as shown below. Center of the hull Center of the hull Recommended installation location Narrow space installation location ※ Side thruster...

[The gear oil needs to be replaced at least every two years_200㎖] ※ If oil is not present in the oil reservoir, it is the main cause of damageto gearleg and bearings. 2. The inside of the tunnel, propellers, and gearleg must be kept clean to prevent barnacles from growing with anti-pollution paint. ※ Barnacles in tunnels can reduce thruster’s propulsion force. 3. When checking the ZINC ANODE, replace it if more than half disappeared....
