Before the Oil Crisis in 1974, majority of oceangoing ships utilizes a Main Boiler for its steam source. One such type of ship is an Oil Tanker which uses a Steam Turbine for its propulsion while the flue gas is processed and used to inert the oil tanks thereby preventing an explosion during cargo operations. But after the Oil Crisis, steam propulsion gave way to diesel propulsion because the latter consumes less fuel and its efficiency was improved because of some modifications such as utilizing the waste heat to produce freshwater out of seawater and steam production using the economizer. That is the reason why most of the oceangoing ships today, is using an Auxiliary Boiler instead of the massive Main Steam Boilers to heat oil tanks, heating during winter time and for cooking food in the galley to name a few.
Requirements for the Bachelor of Science in Marine Engineering(BSMarE)
In order to comply with the Revised Curriculum for Bachelor of Science in Marine Engineering (BSMarE) in compliance with CHED Memorandum Order # 67 series of 2017 and Annex C.2 of Joint CHED-MARINA Memorandum Circular No. 02, series of 2019, an Operational and Functional Boiler is needed in order to be utilized for the following subject in BSMarE course namely: Power Plant 2- STEAM PLANT. One such equipment that complies with this requirement is the COMPACT STEAM TURBINE POWER PLANT from ESSOM.
