A Naval office was set up in Chennai in the early 1940s. The first Naval Officer-in-Charge (NOIC) was Captain R. A. Malhuish. In 1946, the NOIC was re-designated Resident Naval Officer (RNO). With INS Adyar being recommissioned in 1954, the strength of the naval base grew and in 1968, the RNO was designated NOIC (Madras), and was responsible to the Flag Officer Commanding-in-Chief Eastern Naval Command. The NOIC (Madras) also discharged the duties of Commanding Officer INS Adyar.^[1]

With increasing responsibilities, a new appointment of NOIC (Tuticorin) was created in December 1994.
