Engineering ship maintenance decision support system is needed in order to secure the safety in the process of engineering ship operation.

In this paper, the analysis and research of the lines design feature for ocean engineering ships, especially for tug, salvage and standby ship, that are in demand in recent market, are carried out.

This paper mainly discusses the lengthening alteration of beaching wedged chassis originally designed for slipping of caissons for repairing large engineering ships.

The OPC Technology and Its Application in Real-Time Monitoring System for Project Ship;

This paper proposes a dynamic navigation system for project ships on the basis of GPS s positioning technology and developing instruments of visual procedure.

Parametric Design and Structure Analysis of Working Ship;

Real time monitoring the operation of working ships is an important measure for improving the quality and efficiency of waterway dredging project.

Increasing an every more significant role of the working ship together with the inappropriate and chaotic management of fixed assets and the deficiency in the term for a ship-depreciation concerned make man a sobering thought.
