The paper investigates a nonlinear vibration mitigation strategy of a variable length
pendulum subjected to a harmonic external excitation. A nonlinear absorber in a form of a tri …

In practice, offshore cranes are effective transportation tools used on ships. Different from
land-fixed cranes, offshore cranes work in the noninertial frame, which are usually affected …

This study analyses dynamic influence of stochastic vibro-impact ship behaviour on the
ship's launch and recovery capability. To deliver cargo and people to the Arctic regions …

Purpose The purpose of this paper is to review maintenance practices, tools and parameters
for marine mechanical systems that can be classified as plant, machinery and equipment …

Polar research has important scientific value has brought attention of many countries and
motivated further exploration of new technologies for enabling operations in the adverse …

Offshore crane systems are widely employed to transport cargoes on vessels due to their
outstanding flexibility. However, they always suffer from various disturbances in the special …

In practical applications, offshore cranes are widely utilized on large scale ships to
accomplish the tasks of transferring cargos from one ship to another or between ships and …

An offshore ship-mounted crane consisting of a trolley, a wire, and a payload, is a typical
nonlinear underactuated system, which suffers from unmatched disturbances mainly caused …

The paper proposes and investigates nonlinear vibrations mitigation strategies of an
externally excited pendulum. This problem is highly relevant to the crane's payload …

From the practical perspective, with large-scale cargoes or nonnegligible hook masses, the
centers of gravity of cargoes and hooks do not coincide with each other, and shipboard …
