Abstract:
Material handling equipment is designed or selected based on two factors, the aspects of technical and economic. Technical aspects of a boatlift are designated by technical specifications that can meet with the need to lift and move a boat from land to waterway and vice versa. Boatlift is a type of Rubber Tyred Gantry crane specifically designed for moving of small craft, small and medium vessels with a capacity of 10 tons to 600 tons. Boatlift with a capacity of 5 tons is very rarely to find and very different from other types of cranes such as overhead cranes that are easy to find. Boatlift

Abstract:
Lifting is a frequently used offshore operation. In this paper, a nonlinear model predictive control (NMPC) scheme is proposed to overcome the sudden peak tension and snap loads in the lifting wires caused by lifting speed changes in a wind turbine blade lifting operation. The objectives are to improve installation efficiency and ensure operational safety. A simplified three-dimensional crane-wire-blade model is adopted to design the optimal control algorithm. A crane winch servo motor is controlled by the NMPC controller. The direct multiple shooting approach is applied to solve the nonlinear

Abstract:
One of the major tasks in carrying out open-pit mining operations is timely and high quality maintenance and repair of mining equipment, in particular, mechanical shovels, which secures a required availability level. The most loaded are the lift and pressure drives of the shovel's working attachments, which significantly increases the risk of failure of their components. An adequate assessment of the loads acting on these drives through analyzing the changes in currents and voltages of their motors makes it possible to adjust the time between maintenance.

Abstract:
The optimal mode of towing fishing gear has a direct impact on the energy efficiency of the fishing vessel. To build the combined traction characteristics of the vessel and trawl systems, data are needed on the nominal moments on the winch and engine drum, as well as the traction force in the warp. Estimation of the movement parameters of the towed object will make it possible to haul warps without overloading the trawl winch and the main engine. The paper proposes a block diagram of the algorithm for estimating the motion parameters of a trawl system. Processing of the current measurements of

Abstract. The work deals with the possible assessment of the energy efficiency of modern passenger elevators. Special attention is paid to the issue of recuperation, as the most energy-efficient type of braking. A method is proposed that allows you to qualitatively and roughly estimate the possibility of recuperation in arbitrary elevator electric drives, based on the catalog parameters that are present in open sources. The limiting value of the equivalent efficiency coefficient of the elevator electromechanical system, at which there is no energy recovery in the "start-up-braking" cycle, was

In the Russian Federation, a significant part of the forest fund territory is located on permafrost. Many regions of the country have large reserves of mature and overmature commercial forests, and a significant part of these reserves are located in hard-to-reach places, not only due to the underdeveloped road network, but also due to the difficult terrain. Currently, the vast majority of timber harvesting in Russia is carried out using modern machine complexes, mainly including wheeled forestry machines of various layouts and purposes (harvesters, forwarders, skidders, etc.).

Abstract:
Abstract Floating offshore wind turbines (FOWT) offer unique operational and maintenance (O&M) challenges and opportunities compared to their fixed-bottom counterparts. Situated further from shore, FOWT benefit from stronger, more consistent winds, but this increased distance leads to longer travel times and harsher conditions, reducing accessibility. Traditional jack-up vessels become impractical in deeper waters. Additionally, the inherent motions of FOWT introduce complexity to maintenance strategies. As wind turbine dimensions continue to grow, major component replacements (MCR) requir
