Abstract： This paper describes the design of the 60m seafloor multi-function drill under development. The whole system is divided into 3 subsystems： the prototype of the drill itself， the launch & recovery subsystem and the in-site measurement subsystem. Several newest technologies such as wire coring， multiple oil pumps， specially designed driving head and drilling tools， etc are applied in the drill itself. The L & R subsystem has a special V shaped rail. And the newly developed sonic data transmitting technique is adopted in the in-site measurement subsystem. And the sea trial plan is presented at the end of the paper.

Key Words： Design report； Seafloor drill； Wire coring
