Dominion Energy, a large USA energy supplier with 7 million customers across 16 states, recently completed a 12-MW, two turbine, offshore wind energy project. The Coastal Virginia Offshore Wind (CVOW) pilot project is located 27 miles offshore and provides enough safe, clean, reliable, and affordable energy to power up to 3,000 homes. It is the first offshore wind energy project in federal waters, and only the second offshore wind project in the United States.


The construction-zone perimeter and cable-laying areas had to be marked with private Aids to Navigation (PATONs/AtoNs). These would help ensure safe operation of nearby service and passenger vessels, allowing construction to proceed safely on schedule. Both the buoys and lanterns had to be made in the United States of America, and deployed on a strict deadline. Dominion Energy, through its offshore contractor Orsted, contracted with Cape Henry Launch Services to deliver the marking solution.


Sealite supplied Cape Henry Launch Services, with two different buoys for the CVOW pilot project: SL-B1750 Poseidon and SL-B700 buoys. Also supplied was Sealite’s 3-5NM solar, self-contained SL-75 marine lanterns.

Sealite buoys feature large float sections for optimal visibility and stability for coastal and offshore deployment locations. Internal, stainless tie bars connect lift and mooring points for added strength and durability. And since all Sealite buoys are made from lightweight, environmentally friendly polyethylene, they are lightweight and easy to deploy.

The SL-75 solar, self-contained 3-5NM marine lanterns were used to increase buoy visibility at night and in foul weather. The Bluetooth enabled lantern provides remote programming of flash characteristics and intensity from a distance of up to 164 ft/50m. This convenient feature reduces the need to climb the buoy for maintenance, increasing crew safety.

Cape Henry Launch Services used the SL-60 Solar Marine Lanterns on the SL-B700 buoys. With a range of 2-3NM, the SL-60 is ideal for shorter range applications, like the coastal punch-out site where transmission lines meet the water.

Cape Henry Launch Services trained staff and fleet of vessels oversaw the deployment of the private ATONs. Like all Sealite products, the SL-B1750 and SL-B700 buoys fully comply with US Coast Guard regulations and follow International Associated of Marine Aids to Navigation and Lighthouse Authorities (IALA) standards.


The CVOW wind energy pilot project is now fully operational. It is the first wind energy lease that is owned and operated by an electric utility company.

The permitting and subsea work done by Dominion Energy for the CVOW pilot project will help inform their future development efforts for a larger, 2.6 GW, 188-turbine project on an adjacent lease site. The future project is expected to be online in 2026. When completed, it will be the largest offshore wind project in North America. It is expected to create an estimated 1,100 jobs, bring $210 million in annual economic impact once operational, and power up to 660,000 homes.

With a superior rotational molding manufacturing process and the use of premium materials such as UV resistant polyethylene and closed-cell polyurethane foam filling, the Sealite buoys will be repeatedly used by Cape Henry Launch Services to mark future wind energy and marine construction projects, providing an excellent return on investment.


“Great service and a really durable product allowed us to deliver an excellent marking solution both on-time and budget for our customer, Dominion Energy.”

What Our Client's Say

On behalf of Karachi Port I am pleased to acknowledge your good service and provision of the new SL-75 solar marine lanterns installed by your firm in the harbour channel at Karachi Port. The new lanterns are very feasible and useful and equipped with the latest navigational technology.

[Re: Sealite SL-LED Lightsource at LaCorbiere Lighthouse], We were impressed with Sealite’s solution which provided a modern, reliable and efficient light source whilst remaining sympathetic to the lighthouse’s heritage and significance as a local landmark, but most importantly to improve upon reliability and to continue its vital role in aiding the safety of navigation in Jersey’s waters, as it has done for nearly 130 years.

-Aaron Gavey

[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 shortly. Keep up the good work.

-Capt Andy Suddes

[Re: Installation of WindTalker for kite-surfing club], The WindTalker™ is a big success here in Cyprus, thanks to your after sales support the unit is now functioning perfectly.

-Christophe Meletiou

We choose to sell Sealite … this is a long story, well we treat Sealite as our own and the relationship we have developed with Jeff and Chris and their attitude and commitment towards growing Sealite to this stage is remarkable. We feel at home when talking to them and the staff of Sealite and this in turn gives us more security and strength in selling products in India.

-Aliasgar E Patrawala

[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.
