What is AMOSUP?

The Associated Marine Officers’ and Seamen’s Union of the Philippines (AMOSUP) plays a vital part in the lives of many Filipino seafarers. 

Founded to protect and promote the rights and welfare of seafarers, AMOSUP has grown into a comprehensive organization with a wide range of programs and services. 

Let’s delve into its history, membership details, and the services it offers to its members.

History of AMOSUP

On November 11, 1960, Capt. Gregorio S. Oca established the Associated Marine Officers’ Union of the Philippines (AMOUP) to address the concerns of licensed crew members from various shipping lines. 

At the same time, Brother Donato Alarcon formed the Associated Seamen’s Union of the Philippines (ASUP) to represent the unlicensed crew. 

In 1972, these two unions merged to create the Associated Marine Officers’ and Seamen’s Union of the Philippines (AMOSUP), affiliating later with the International Transport Workers’ Federation. 

Today, AMOSUP boasts a membership of about 80,000 overseas Filipino seafarers

Capt. Oca, as the elected President, envisioned AMOSUP as a union that not only protects the rights of seafarers but also provides them with world-class training and healthcare services.
