Spillway Flow Control
The spillway required gates that could support controlled water releases as reservoir levels changed.
PROJECT CASE STUDY
Gate and Hoist Equipment for Nam Vela Hydropower Station
FUDA supplied radial gates, gate hoists, and trash racks for the Nam Vela Hydropower Station in northern Laos. Explore the equipment scope, technical specifications, and delivery highlights of this project.
The Project
Project Overview
Located in northern Laos, Nam Vela Hydropower Station includes a reservoir, spillway, and intake structures that support water management for power generation. The project called for equipment to control water releases, operate gates, and protect the intake from floating debris.
FUDA supplied radial gates, gate hoists, and trash racks for the station. Together, these components address flow control, gate operation, and intake protection across the project’s water-control structures.
Engineering Context
Project Requirements
The station’s spillway and intake presented three connected water-control requirements. Each influenced the selection and arrangement of the equipment supplied for the project.
Gate Operation & Maintenance
The gates needed suitable hoisting equipment and practical access for inspection and maintenance.
Intake Debris Protection
The water intake needed protection from floating debris, with access for regular cleaning.
FUDA’s Contribution
Equipment Supplied for the Project
FUDA supplied a coordinated equipment package for the spillway and water intake, covering gate structures, gate operation, and intake debris protection.
Application: Spillway
Radial Gates
Radial gates form the primary flow-control equipment at the spillway. They provide a controlled path for releasing water from the reservoir as operating conditions change.
Application: Spillway Gates
Winch Gate Hoists
Winch gate hoists provide the lifting equipment needed to operate the spillway gates. Their role is to support gate opening and closing during normal operation and maintenance.
Application: Water Intake
Trash Racks
Trash racks provide a protective barrier at the water intake, helping limit debris entering the waterway while allowing access for routine cleaning.

Project Execution
Engineering & Delivery
The Nam Vela equipment package required coordination across the spillway gates, hoists, and water-intake protection. The following stages show how the equipment moved from project requirements toward delivery.
-
Equipment Coordination
Gate openings, hoist arrangements, and intake-rack interfaces were reviewed together so the supplied components matched their intended locations within the project.
-
Fabrication & Inspection
Gate, hoist, and trash-rack components were fabricated and checked against the agreed equipment drawings before packing and dispatch.
-
Delivery & Site Support
The equipment was prepared for shipment with documentation for on-site handling. FUDA coordinated technical questions during the project handover.
Delivery Status
Project Outcome
FUDA completed the supply of radial gates, winch gate hoists, and trash racks for Nam Vela Hydropower Station. The equipment package and supporting technical documents were handed over for integration at the spillway and water intake.
