INGENIEUR Edward Place. Mitchell’s Pier (also known as Bagan Tuan Kechil Pier) was situated around the present day North Butterworth Container Terminal. The ferry service thrived and in 1922 was taken over by the Penang Harbour Board, which is the predecessor of Penang Port Commission. Bigger steam ferries were introduced and in 1925 motorised vehicles (besides passengers and goods) were being transported across the strait. Initially, the Penang Harbour Board operated the ferry at Church Street Ghaut Wharf. Later it was demolished and replaced by the Church Street Pier which has been restored and is still standing. In 2017, the Malaysian Federal Government began the takeover of the ferry service and transferred it to Prasarana Malaysia, a Government linked company (GLC) which oversees urban public transportation across the country. Following this takeover, the Penang shuttle ferry was rebranded as Penang Rapid Ferry. As stated earlier, the present Penang Rapid Ferry operates between Raja Tun Uda Ferry Terminal on the island and Sultan Abdul Halim Ferry Terminal on the mainland. In the post war years, there were three steam ferries – SS Violet, Elizabeth and Pelangi plying the strait. With the advancement of shipbuilding technology, steam ferries were finally replaced by more powerful and efficient diesel-powered 6 38 VOL 2018 VOL 74 55 APRIL-JUNE JUNE 2013 ferries. From 1971 until 2002, nine diesel ferries were built and named after islands like Pulau Labuan (built in 1971), Pulau Rawa (1975), Pulau Talang Talang (1975), Pulau Undan (1975), Pulau Rimau (1980), Pulau Angsa (1981), Pulau Kapas (1981), Pulau Payar (2002) and Pulau Pinang (2002). At present, only six are still in active service. Depending on the size of the ferry, deadweight tonnage (DWT) or maximum allowable cargo varies from 100 to 440 tonnes. The newest ferry, Pulau Pinang, has an overall length of 56m, breadth of 11.6m and depth of 3.7m. It is fitted with two engines with a combined power of 1650kW. The entire ferry is made of steel plates and beams which provide sufficient rigidity and strength to carry the intended cargo. All ferries have been designed with a similar shape and geometry, consisting of two decks and four interchangeable entrances at the stern sections to roll in and roll out cargo. The lower deck is exclusively used for carrying vehicles while the upper deck is either for passengers or smaller vehicles or both. There are two navigation bridges, each located at the stern above the upper deck. The ferry’s diesel engine is designed to drive two sets of vertical rotating blades to generate omni- directional thrust. This design provides greater manoeuvrability especially for docking and undocking at the terminals. The docking bridge is
