The Seaward Defence Boats are large patrol craft in service with Indian Navy.
Midlife Refits
The ships of this class built with low strength mild steel and thin plates had low corrosion tolerance. As such adhering to prescribed docking intervals was essential.
The SDB T 54 was commissioned in September 1982. Its medium refit was due in March 1988 and long refit in April 1992. Ignoring the vulnerability to corrosion of this ship, medium refit was delayed by over three years, which was carried out during July 1991 to April 1992. As a result, long refit could not be planned. However, another short refit including replacement of engine was taken up in December 1993. The short refit was converted into medium refit in February 1994. While carrying out repairs, extensive damage to underwater hull was noticed in March 1994. The medium refit got prolonged up to May 1996 because the engine and other material procured for this ship were diverted for carrying out ongoing repair of another similar (SDBT-55) ship.
