Floating Helipad Project at Qiandao Lake, China | Custom HDPE Pontoon Solution

Project Case Study: A Customized Floating Helicopter Landing Platform for Aerial Sightseeing Operations

Project Overview

Located in Zhejiang Province, China, Qiandao Lake (Thousand Island Lake) is renowned for its spectacular scenery and tourism attractions.

To support helicopter sightseeing operations by Zhejiang Yunzhou General Aviation, a floating helicopter landing platform was developed near the Hilton Hangzhou Qiandao Lake Resort.

Hisea supplied a customized HDPE floating pontoon system for the project, providing the flotation foundation for a specialized water-based helicopter landing facility.

The project demonstrates the application of modular floating technology in specialized aviation infrastructure and tourism development.

Project Challenges: Stability, Load Capacity and Changing Water Conditions

Unlike conventional floating docks used for boats and pedestrian access, a floating helipad requires careful consideration of structural stability, loading conditions, and environmental factors.

The Qiandao Lake project presented several key challenges:

• High load requirements: The floating support system needed to accommodate the structural loads associated with helicopter operations.
• Landing impact loads: The platform design needed to account for dynamic forces generated during helicopter landings.
• Water level fluctuations: Seasonal variations in lake levels required a floating structure capable of adapting to changing conditions.
• Wind and wave exposure: The platform needed an appropriate layout and mooring arrangement to manage movement caused by environmental conditions.
• Long-term durability: The flotation system required materials suitable for prolonged freshwater exposure and outdoor operation.

To address these requirements, Hisea developed a customized modular HDPE pontoon configuration based on the project’s technical specifications.

Our Solution: Custom HDPE Floating Pontoon System

1. High-Strength Floating Support Structure

Hisea supplied an HDPE floating pontoon system designed to provide buoyancy and structural support for the helicopter landing platform.

The pontoon layout was configured to distribute loads across the floating support system and accommodate the project’s structural design requirements.

This approach allows modular floating technology to be applied to specialized structures with demanding load requirements.

2. Optimized Floating Platform Layout and Mooring Design

Stability is a critical consideration for any floating helicopter landing facility.

For the Qiandao Lake project, the floating pontoon arrangement and mooring configuration were designed to help manage platform movement under changing water and weather conditions.

The system was also intended to accommodate variations in lake water levels while maintaining the platform’s functional position.

3. Durable HDPE Material for Long-Term Outdoor Use

The floating pontoons are manufactured from high-density polyethylene (HDPE), a material widely used in marine and waterfront applications.

Its key advantages include:

• Excellent resistance to water and corrosion
• Resistance to impact and general outdoor exposure
• UV-resistant material formulation
• Low-maintenance flotation components
• Modular construction for flexible installation and maintenance

These characteristics make HDPE pontoons a practical choice for floating infrastructure exposed to challenging environmental conditions.

4. Modular Design for Customized Engineering Applications

The floating support system uses modular components that can be arranged according to project requirements.

This design approach provides flexibility in platform dimensions, flotation layout, installation planning, and future maintenance.

It also demonstrates how HDPE floating pontoon systems can be adapted beyond traditional marina docks and recreational floating platforms.

Project Highlights and Application Value

The Qiandao Lake floating helipad project demonstrates how a customized HDPE pontoon system can serve as the flotation foundation for specialized waterfront infrastructure.

By considering load distribution, water level fluctuations, and environmental conditions, the floating support system was configured to meet the project’s specific requirements.

This case highlights the potential of modular floating pontoon technology for applications beyond conventional boat docks, particularly projects requiring customized flotation arrangements and structural support.
