Several new types of deepwater anchors widely used in the world

including suction anchor

vertically loaded anchor

suction embedded plate anchor and dynamically penetrating anchor

are detailedly illustrated. Based on the overview of recent works at home and abroad

some key and hot problems are presented and discussed briefly

which are the seabed resistance and soil heave development during the suction penetration process of suction anchor

the anchor capacity in service

the drag trajectory of vertically loaded anchor and its capacity under a three-dimensional loading state

keying process of suction embedded plate anchor

installation depth of dynamically penetrating anchor and its pullout capacity. Hence

the deficiencies in current design

field installation and bearing mechanism can be recognized

aiming to explore the new developing trend of deep-sea anchoring foundations.
