AI Technical Summary

Technical Problem

The existing ultra-large piling vessels lack a global dynamic linkage control between the main hydraulic cylinder system and the hull, pile frame, power grid, and anti-roll system, resulting in low operating efficiency, high energy consumption, and poor safety, making them unsuitable for construction needs in all deep-sea scenarios.

Method used

Through multi-dimensional collaborative optimization methods, dynamic linkage control between the main hydraulic cylinder and various subsystems is achieved, including navigation-operational altitude collaborative control, shallow water-buoyancy adaptation collaborative control, power grid-hydraulic cylinder energy efficiency collaborative control, seakeeping-attitude stability collaborative control, and safety-life warning collaborative monitoring, thus constructing a global linkage mechanism.

Benefits of technology

It has achieved a breakthrough in adaptability to all scenarios, greatly improved system collaboration efficiency, significantly enhanced green energy-saving effects, and upgraded safety and stability performance, solving the industry pain points of traditional equipment having single functions and insufficient collaboration.

Abstract

This invention provides a collaborative optimization method for the main hydraulic cylinder system of a super-large piling vessel adapted for deep-sea applications, belonging to the field of marine engineering equipment technology. This invention constructs a five-dimensional collaborative system encompassing navigation, shallow water, energy conservation, seakeeping, and safety, including: multi-scenario requirement analysis; navigation-operational height collaboration, enabling rapid folding of the piling frame via quick-change interfaces; shallow water-buoyancy adaptation collaboration, linking the buoyancy tank to adjust draft and optimize hydraulic cylinder thrust; power grid-hydraulic cylinder energy efficiency collaboration, maintaining the main engine's economical load through energy storage regulation; seakeeping-attitude stability collaboration, linking anti-roll tanks and dampers to suppress roll; safety-lifespan early warning collaboration, predicting component lifespan based on digital twins; and full-condition benefit assessment and parameter iteration. This invention achieves dynamic linkage between the main hydraulic cylinder and various subsystems, solving the pain points of poor adaptability and insufficient collaboration in traditional equipment across all scenarios, significantly improving operational efficiency, energy conservation, and safety.
