"plan de construcción naval continua" (continuous naval construction plan in spanish) of the Chilean Navy. SHOA The Servicio Hidrográfico y Oceanográfico de la Armada de Chile (SHOA, Spanish for Hydrological and Oceanographic Service of the Chilean Navy) is an agency of the Chilean Navy managing situations dealing with hydrology and oceanography including tides and tsunamis. SHOA is also the official Chilean government timekeeper. Ranks and rates Ranks and rates are shown on the sleeves of all Chilean Navy summer uniforms (and on the shoulder boards on winter or summer service uniforms as well for officers and WOs only). Shoulder and sleeve ranks are inspired by those in the British Royal Navy, the French Navy and the German Navy. Officers, WOs and NCOs of the Marines add the Infante de Marina (Marine Soldier) title to their ranks from Seaman onward, as the Marines are part of the Navy. All officers, active or reserve, study at the Arturo Prat Naval Academy and later in the Naval Polytechnic Academy and the Naval War Academy receive improved training and education to be promoted as well as training in his/her specialty field while all active and reserve NCOs (known in the Navy through the general term Men of the Sea) study at the Seamen's School of the Navy "Alejandro Navarette Cisnerna" and later in the Naval Polytechnic Academy and its attached and independent colleges for later specialty training.
