Precision Sector Light PEL-4 Installed on the Iconic Lions Gate Bridge Vancouver, Canada
Go Deep International (GDI) collaborated with the Canadian Coast Guard’s Western Region (CCG) and the Vancouver Fraser Port Authority (VFPA) to enhance marine navigation aids at the First Narrows passage—the entrance to Vancouver Harbour beneath the Lions Gate Bridge.
The project aimed to improve navigational safety for both incoming and outgoing vessel traffic in this critical waterway.
The Challenge
The project presented several unique challenges:
- The Lions Gate Bridge’s height above the passage created a vertical divergence issue—navigation aids needed to be visible both at close range and from greater distances
- Equipment needed to be mounted below the bridge superstructure at the center of the channel
- The system required reliable operation in a busy marine environment with varying vessel bridge heights
- Minimal maintenance requirements were essential due to the installation location
The Solution
Based on CCG’s detailed specifications for sector angles and operational environment, GDI developed a customized solution leveraging their previous experience with sector light projects:
- Dual PEL-4 Configuration: Two PEL-4 lights were installed in tandem—one angled to serve vessels at a distance and the other positioned for vessels approaching the bridge. This arrangement created a sector light with a 13.4-degree vertical divergence, significantly exceeding standard sector light capabilities.
- Air Draft Awareness System: Four LED 160 lanterns with wire-based synchronization were installed to provide incoming and outgoing vessels with clear indication of air draft clearance under the Lions Gate Bridge.
Key Benefits
The PEL-4 Sector Light solution was selected for several advantages:
- Superior Vertical Divergence: The PEL-4’s exceptional vertical divergence compared to alternative sector lights on the market was fundamental to the project’s success
- Low Maintenance Design: LED light source eliminated the need for lamp changers and replacement lamps
- Advanced Oscillating Boundary System: Allows for up to 7 distinct sectors with precise boundaries
- Reliability: Virtually maintenance-free operation in a challenging marine environment
Project Context
This installation builds on GDI’s successful track record with CCG Western Region, including previous projects such as a PEL-6 installation at Second Narrows in Vancouver Harbour and an on-demand Double PEL-6 system at the Port of Prince Rupert designed for enhanced sector coverage and daytime intensity.
