As a type of indispensable oceanic transportation tools, ship-mounted crane systems are
widely employed to transport cargoes and containers on vessels due to their extraordinary …

Ship-to-ship load transfer with offshore cranes is challenging in rough sea conditions
because of the difficulty in compensating for the increased position-velocity-acceleration …

We propose, in this paper, an observer-based nonlinear feedback controller for four degrees
of freedom (4-DOF) offshore ship-mounted tower cranes, which includes a robust-type term …

Payload sway for shipboard cranes represents a significant safety concern for deck
personnel. In this paper, a generalized trajectory modification strategy is presented that can …

With the increasing demands of high-precision hoisting, a growing number of to-be-hoisted
large-scale heavy payloads not only need accurate positioning transportation, but …

An active motion compensated gangway is important and efficient equipment for personal
transferring from a supply vessel to wind turbines or other structures, vice versa. This paper …

In this paper, a framework for relative motion compensation is presented and demonstrated
via simulation with kinematic crane-tip control. The method allows for compensation relative …

Ship motion has significant effects on certain maritime applications like offshore crane
operation. In particular, the vertical heave motion is undesired for safe transferring, accurate …

This paper presents the implementation of the virtual prototy** system for maritime crane
design and operations. The study is designed to bridge the following gaps in maritime crane …

A new hybrid electro‐hydraulic and pneumatic actuator system and its dynamic model for
high‐performance control are presented. This work focuses on tracking control of rapidly …
