Much prior to placing of the above buoys in the gulf of Kachchh, an unmanned light ship was laid at Lushington shoal during 1966-67. The light ship had to be with drawn due to drifting away every time it was laid. It was later on transferred to Bombay Port Trust. 

During 1976-77, a newly designed floating light known as ‘Saurus’ tower was laid into the sea - off Okha approximately towards Mithapur. The hull supporting the tower for light could not remain stable and horizontal and so the ‘Saurus’ tower was also withdrawn from the sea.

It was then decided to demarcate the deep water channel leading to SBM Vadinar by a series of eleven buoys. As such a regular Buoy yard was provided at Okha Lighthouse in 1979 to extend logistic support to MV Sagardeep for its Buoy operations as well as to stock Buoys and moorings. In the year 1980 Sixteen BS-58 Buoys manufactured at New Bombay under licence from AGA, U.K., together with necessary moorings were supplied at Okha. In the year 1981 eleven BS-58 Buoys were laid at different co-ordinates in the gulf of Kachchh in order to mark the Salaya deep water channel.

Sixteen Hitech Elastamer Buoys with solar operated equipments, manufactured by M/s Balmoral Marine, U.K were imported in 1995 for replacing the BS-58 buoys in phases.
