History

Original Ambrose Light Station, a Texas Tower built in 1967.
Original Ambrose Light Station, a Texas Tower built in 1967.

The original light station was put into operation on August 23, 1967, replacing the obsolete Lightship Ambrose, and cost $2.4 million. The tower design was a Texas Tower, a very strong steel pipe structure based on the oil platforms built for use in the Gulf of Mexico. The structure was prefabricated in Norfolk, Virginia and shipped in sections on barges for assembly on-site. The tower station was situated about 7.5 miles off of the coast of Sandy Hook, New Jersey in approximately 70 feet of water and was supported by four 42 inch steel pipes, sunk down about 245 feet to the bedrock. The light was about 136 feet above mean low water and the 10,000,000 candle-power light could be seen for 18 miles. Image File history File links Ambrose_Lighthouse. ...

The lower deck was designed for fuel and water storage while the top deck served as living quarters for a 6 to 9 man crew. The roof of the platform also served as a flight deck for helicopters, the main mode of transport to and from the station for crew rotations. The tower was automated and the crew was removed from duty on October 15, 1988. Ambrose light station was controlled electronically by the United States Coast Guard station on Governor's Island until the island and base were transferred to New York State and City for $1 in 2003.

In October 1996, on a clear night the 754 foot Greek oil tanker Aegeo struck the tower, causing severe damage. It was discovered that the light was not functioning when the tanker hit the tower (i.e. at the time of the allision). The Aegeo's captain was later found to be at fault. Three years later, in September 1999 after repairs were deemed insufficient, the old structure was razed by the U.S. Army Corps of Engineers and replaced with a new tower. The new tower was built about 1.5 miles East of the old site, and is approximately 76 feet above mean low water, and the 60,000 candle-power light is visible for 18 miles.
