Background

In September 2019, the Commonwealth of the Bahamas was hit by Hurricane Dorian, a category 5 storm. Targeting Grand Bahama Island and its 380,000 residents, the hurricane left more than 25% of the population homeless. The islands’ electrical grid and cell towers were destroyed, leaving it without power and almost no communication infrastructure. The airport was almost completely submerged making rescue and recovery extremely challenging. The hurricane left several oil and gas terminals badly damaged.

After initial rescue and recovery efforts, support vessels needed port access to deliver critical cleanup supplies. Ports needed to reopen quickly.

Challenge

One oil and gas terminal was greatly impacted by Hurricane Dorian. Navigation buoys, shore-based Aids to Navigation (AtoNs) and long-range port entry lights were lost or sustained significant damage. Clean-up vessels could not safely enter the terminal’s channel. This prohibited the delivery of recovery equipment and other infrastructure support that was critically needed for recovery efforts.

Sealite project partner Navmoor Ltd. in the United Kingdom arrived on Grand Bahama Island shortly after Hurricane Dorian. Assisted by local harbor pilots, Navmoor assessed the channel from buoy to berth and identified:

  • The original channel access (before Hurricane Dorian)
  • How it had shifted
  • Which critical AtoNs needed to reinstate safe vessel access to the terminal
  • Where the IALA compliant AtoNs needed to be deployed

Solution

Working in 104°F/40°C temperatures, driving rain, frequent water spouts, and with minimal repair equipment, the contractor re-installed two spar buoys at the channel entrance. These buoys served as a high-visibility gateway for entering vessels. SL-60 Solar LED Marine Lanterns were positioned along the waters’ edge to mark the outer channel. Their 2-3NM range provided temporary marking for shallow drafted vessels until the inner channel could be charted.

Next, the mast-mounted Port Entry Light (PEL) was repaired. The PEL-10 directs larger vessels on long distance approaches, helping them to navigate to the newly laid out channel.

Sealite’s PEL-10 provides a range of 3.5NM (daytime)/19+NM (nighttime) range. It gives mariners a clear line-of-sight to the oil terminal approach. The PEL was easily repaired since it uses no moving parts. It draws a mere 30 watts, and is highly energy efficient. Sealite’s PEL was the optimal solar long-range lighting solution since mains power was unavailable due to hurricane damage to the electrical grid.

Two Sealite SL-75 Bluetooth® enabled Solar LED Marine Lanterns were mounted to the newly reconstructed mast to further enhance safety around the newly shifted sandbars and navigation hazards. The SL-75’s feature a 360° horizontal output and 3-5NM range, adding visual reference for vessels not yet on-bearing to the PEL. Installation and maintenance personnel remotely programmed the lantern using the Bluetooth feature. Remote programming eliminates the need to climb the mast and increases safety for personnel.

Sealite’s SL-B1250 and SL-B1750 navigation buoys in can and nun configurations were deployed to mark the new channel. All of Sealite’s buoys are made from lightweight polyethylene, enabling them to quickly and easily be towed on-station via the molded-in stainless lifting eye.

Sealite’s SL-70 Solar LED Marine Lanterns were added to the SL-B1250 and SL-B1750 buoys for optimal visibility at night and in foul weather. The SL-70 utilizes a high-intensity LED, is made from long-lasting, durable, and UV stabilized polycarbonate, and offers more than 30 days of autonomy.

Sealite’s optional GPS synchronization was incorporated into all the lanterns. This feature enables the PEL-10, SL-75, SL-70, and SL-60 to flash in synchronization, helping to identify the channel and distinguish a safe line of passage. Sealite’s optional GSM cell phone monitoring was also incorporated into all the of AtoNs. GSM monitoring provides a convenient, remote way for the local maritime authorities to continuously observe the operational health and status of all Sealite marine lanterns.

Outcome

Sealite’s shore-based and floating Aids to Navigation helped re-establish vital vessel entry into the oil and gas terminal on Grand Bahama Island. Urgent deliveries of supplies and equipment were enabled to help the rebuilding and recovery efforts in the disaster-stricken area following the worst natural disaster in the country’s history.

 

“With manufacturing facilities in the USA, Sealite was able to meet the urgent delivery requirements for this project. The team was able to get this severely damaged, critical navigation system functioning for the customers’ needs.”

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.

[Re: Sealite Solar-Powered LED Area Lighting system], We chose the Sealite system for the Jacobs Well Queuing Pontoon due to our previous experience with Sealite ™s product, its durability and construction.

-Peter Taylor

I just wanted to say thank you for the light and bracket Sealite supplied to Birkenhead Marina. As the other lights (old ones) need new batteries I will be replacing them with new lights from Sealite and the same brackets that you supplied with the light we received last week … Your product is excellent and the system of setting the light is good also. Thanks again for all your trouble.
