In 1960's moved by the unjust working conditions of the Filipino Seafarers, Capt. Gregorio S. Oca formed the Associated Marine Officers' Union of the Philippines (AMOUP) for the protection of officers working on board commercial ships.

Guided by similar principles and united by the same vision AMOUP unified with Associated Seamens Union of the Philippines (ASUP) forming the Associated Marine Officers and Seamen's Union of the Philippines (AMOSUP) in 1972. From 1972 up to the present, AMOSUP has championed the rights of the Filipino seafarers by negotiating CBA's with foreign shipping companies which has become the standards and by providing unparalled programs and a range of essential services to its members and their dependent.
