This paper presents a comprehensive review and analysis of ship hull cleaning
technologies. Various cleaning methods and devices applied to dry-dock cleaning and …

Numerous marine sessile organisms adhere to ship hulls and increase the sailing
resistance. Antibiofouling paints are employed to maintain the ship performance. However …

There are two challenges for wall-climbing robots in the maintenance and inspection of
large vertical ferromagnetic structures: the requirement of high load capacity and the curved …

Ship inspection is renowned for its hazardous and cluttered working environment. In worst
cases, human operators must risk their lives to reach the almost inaccessible inspecting …

Underwater robots are being developed for various applications ranging from inspection to
maintenance and cleaning of submerged surfaces and constructions. These platforms …

Underwater robot has significant potential to clean the fouling on the ship hull. The design of
robotic solution as well as control scheme is, however, still challenging. The use of negative …

A system includes a first drive module connected to a first end of a linkage arm and a second
drive module connected to a second end of the linkage arm. Two magnetic wheels are …

Featured Application The tracked wall-climbing robot is used for the capacity calibration of
several oil tanks located in Zhoushan city, China. And we also plan to use the robot for the …

To realize fully automatic rust removal from the large splicing weld of a ship hull section, we
proposed a laser vision identification method based on three-line laser structural light. First …

Regular surface-maintenances are necessary for high structures to increase service life. The
traditional manual operation has shortcomings like limited maneuverability, poor operating …
