Orders for further vessels followed. In September 1952 the Commissioners of Irish Lights placed their first order with Philip s. This order was for a lightvessel 119 ft long with a beam of 25 ft and a moulded depth of 15 ft. Unlike Trinity House who numbered their lightships, the Commissioners gave their vessels names, and this first vessel from Philip s was named Gannet at her launch on 6th May 1954. She was handed over in June the same year and left the Dart under tow by the Commissioners tender Isolda.
Gannet is still in service.
The Gannet was followed by two further lightvessels of similar size, launched in 1955. They were the Osprey and Shearwater, both of which gave over 20 years of service before their disposal. A further order from the Commissioners to Philip s was placed in December 1956, when the lighthouse tender Atlanta was ordered. She ran her trials in November 1959 before being handed over on the 30th of that month. She served the Commissioners for 32 years until her sale in 1988 to Falcon Shipping Co Ltd of the Isle of Man, who renamed her Taria.
