Background
The Magdalena River stretches over 950 miles (1528km), from southern Colombia to the large port city of Barranquilla, where it meets the Caribbean Sea. The river has served as a major transportation and commerce route for the import/export of goods, services, and passenger traffic throughout history.

In the 1970s, a bridge was built over the Magdalena River in Barranquilla, which provided a vital transportation link to surrounding areas. The bridge height was only 52 feet (16m), prohibiting larger cargo and passenger vessels from passing underneath.

Challenge
The city of Barranquilla has grown over the decades. Maritime and vehicular traffic has also increased as the city expanded.

Cargo traffic into the port more than doubled over a ten year period, with 10.43 million metric tons handled in 2017. The need to expand inland river navigation and waterway commerce was critical for the future of the port and the city of Barranquilla.

The Pumarejo Bridge Project was commissioned to build a new suspension bridge over the Magdalena River. With a length of 1.4 miles (2.3km), the new bridge would be the longest in Colombia. As the project approached completion in late 2019, a high-risk hazard to navigation was identified. The large concrete abutments and piles used to support the bridge structure posed a safety risk for the safe passage of cargo ships, a distance that spans 164 feet (50m). A solution to the problem needed to be sourced quickly.

Solution
Sealite, in conjunction with Colombian distributor Ingeneria Naval Senalizacion Maritima, worked together to supply and install over thirty SL-70 solar marine lanterns. To stand out from background lighting at Barranquilla port, the lanterns were supplied with GPS modules to enable them to flash at the same time. GPS synchronization is an optimal solution for hazard avoidance and to help pilots and captains identify the navigation channel.

The Sealite SL-70 marine lanterns were chosen for their highly efficient monocrystalline solar panels. These panels are angled to maximize sunlight capture and retain a solar charge. This unique, angled-panel design is optimal for low-sunlight areas such as under bridges or other covered areas.

The robust 2-3NM lanterns offer a minimal cost of ownership and a long service life. The lens and base are molded from durable, UV-stabilized LEXAN polycarbonate. The highly efficient LEDs have a life expectancy of over 100,000 hours.

Outcome
Sealite was able to quickly supply SL-70 2-3NM Solar LED Marine Lanterns with optional GPS Flash Synchronization for the Pumarejo Bridge. The GPS Flash Synchronization clearly identifies the hazardous concrete abutments and piles as a navigation hazard and helps enhance safety for passing vessels.

The new bridge allows bulk carriers and tankers (with a capacity of 15,000 to 35,000 tonnes) to reach inland ports. This helps to expand important global and regional trade, commerce and tourism, and stimulate prosperity for the people living along the river.

 

“With our technical solution using SL-70 Marine Lanterns with GPS Synchronization, Sealite and INSM, will remain in history for their contribution to the construction of the new Pumarejo Bridge, the greatest civil engineering project ever done in Colombia.”

What Our Client's Say

“[Re: Sealite Wins Duke ™s Choice Award for Java Technology & the Environment “ Sealite GSM monitoring & control system], The team at Motorola were extremely impressed with Sealite’s innovative integration of the G24-Java wireless module in their GSM Monitoring & Alarm System.”

“As one of your new distributors (Belize and Honduras, Waller Marine Belize LTD), I would like to express my congratulations to you and your people in providing reliable, dependable and inexpensive products. Formerly we were distributors for a Canadian made product but these were found to be too expensive for the market and also offered only difficult and complicated programming. Our first order of lights from you (SL15 ™S) took only four days to arrive from Aussie Land, when I opened the box they were still flashing. I tested a SL60 (white) for four days (steady on) before it required a recharge…remarkable. I will be placing another order with Dana shortly keep up the good work.”
