Dimension control method for the erection of structures on offshore floating dock

Abstract

For the world's first Offshore Floating Dock(OFD), the dimension control system and method to aim at managing the dimension of offshore blocks in the process of erection are developed. This paper introduces the dimension control system and deals with the method of creating a simplified OFD model and of optimizing ballast-water plan to satisfy the demanded dimension of erected offshore plant blocks. A number of tests and successful application to the Jack & Saint Malo (JSM) offshore plant project was achieved and the results are also introduced.

A Mobile Application of a Decision Support System for Ballasting a Floating Dock

“…The condition of the floating dock largely depends on the quality of its ballasting [10][11][12][13][14]. The relevant ship documentation and the use of computing systems, including those based on mobile devices, allow the calculations necessary to obtain values of stability parameters and loads on the ship's hull.…”
