Bombay Port Trust

Mumbai Port, earlier known as Bombay Port, lies midway (Latitude 18° 56.3' N, Longitude 72° 45.9' E) on the West coast of India, on the natural deep-water harbour of Mumbai. The harbour spread over 400 square kilometres (150 sq mi) is protected by the mainland of Konkan to its east and north and by the island city of Mumbai to its west. The harbour opens to the south to the Arabian Sea.

The first of the present-day docks of the Mumbai Port were built in the 1870s.  Bombay Port Trust (BPT) was established as a corporation on June 26, 1873. BPT's founding chairman was Colonel J.A. Ballard. Port development was undertaken by the civil engineering partnership Sir John Wolfe-Barry and Lt Col Arthur John Barry as Joint Consulting Engineers to the Bombay Port Trust at the end of the nineteenth century.

Lowry refers to the Bombay Port Trust in his novel Ultramarine when Dana is drunkenly tells Popplereuter all officials who have seen him home when he was drunk; "At Bombay it was deputy conservator at the Port Trust." (Pg. 94). The conservator means some officer or body of persons appointed as such under section 7 of the Ports Act, 1908 (Act XV of 1908) to carry out certain tasks in the Port's Marine Department and will include Harbour Master.
