This ferry pier was operated by the Hong Kong and Yaumati Ferry Company Ltd, (HYF), for their services between Hung Hom and Wanchai, Hung Hom and North Point. It is shown at bottom right in the photo below.
The second generation of the Sham Shui Po Ferry Piers was built at Tung Chau Street off Pei Ho Street (todays Tung Chau Street Park). It commenced service in July 1931 (see comments below).
It was operated by HYF and provided services to Central (likely Queen Victoria Street Pier and Central Vehicular Pier later) as well as Sai Ying Pun (Wilmer Street Ferry Pier). (Wikipedia reports that the service to Sai Ying Pun stopped in 1979 when the Wilmer Street Pier was destroyed by a typhoon).
