Over the next seven years, "Beaver" tended SubDiv 16 in Philippine and Chinese waters. As service on the Asiatic Station was influenced by the monsoon seasons, the tender followed a standard pattern of annual operations. In the spring and summer, she shifted base from Manila Bay to Tsingtao, China, and supported submarine cruises up and down the Chinese coast. These included stops at Hong Kong, Swatow, Amoy, Shanghai, Weihai, and Tientsin. From the latter port, leave parties often visited Peking. In the fall and winter, as the monsoons moved southwest toward French Indochina and the Dutch East Indies, the tender and her charges shifted back to the Philippines for operations out of Cavite.
