Provided are an intelligent operation and maintenance optimization method and intelligent production optimization method for an offshore oil subsea production system (SPS), and a system, relating to the field of petroleum engineering. The operation and maintenance optimization method includes: determining whether there is a leak in an SPS; and if there is a leak, performing emergency repair; or if there is no leak, performing intelligent operation and maintenance optimization. The performing intelligent operation and maintenance optimization includes: calculating a static health index of the SPS based on ashore sensor status data and Christmas tree sensor data; obtaining dynamic health indexes at different moments through a Kalman filtering algorithm; and formulating an optimal maintenance strategy for the SPS with optimization objectives of maximizing toughness and minimizing a maintenance cost.
