Abstract: Long gravity piston corer is one of the most common sampling operation on research vessels for geological survey. It focuses on the launch and recovery technique for the long gravity piston corer. Firstly, it briefly introduces the operation principle and working procedure of the corer sampling. Then, it compares the launch and recovery techniques and implementation schemes of several long gravity piston corers, and provides some foresighted suggestions.

Key words: long gravity piston corer, launch and recovery system, manipulation support
