... on crane vessel's motion. INTRODUCTION Floating crane vessels are used for various purposes such as translating, installation and decommissioning of offshore structures, and a high level of safety and precision is required during crane operation. Recently, to maximize the efficiency of the top side...

... ABSTRACT This study carries out a dynamic analysis of the installation operation using offshore cranes in an ocean environment. The analysis is based on multibody dynamics considering various types of external forces, such as wave, wind and current in an ocean environment. The target operation...

...) for the subsequent operations of immersion and underwater connection. It can be seen that each element has to experience a transition state from the mooring in prefabrication yard to the mooring in tunnel site, the latter exposed to current and waves. Further, the natural water depth is shallow, so the element can...

... tracking control and precision mapping are described. In this study, to develop an underwater precise navigation system which is the key technology in the operation of underwater robot, USBL, DVL and FOG sensor data are fused to realize a fast and accurate navigation system with high update rate...

... ABSTRACT Floating Production Storage and Offloading (FPSO) vessels for offshore operations use a Dynamic Positioning system (DP), which includes a controller to correct the position variation of the FPSO subject to internal and external disturbances. Most of these positioning systems use...

...Fully Coupled Analysis of Offshore Deck Mating Operation of a Large Topside Module Sa Young Hong, Bo Woo Nam, Yoon-Jin Ha, Seok Won Hong Korea Research Institute of Ships and Ocean Engineering Yuseong-gu, Daejeon, Korea ABSTRACT A fully coupled analysis has been performed for simulation of offshore...

..., foil-borne operation and different navigational status, non-autonomous combination hydrofoil system can ensure the flotation condition of HYSWATH ship model in the whole sailing process; at the same time, changes of the position and angle of attack of the front hydrofoil have a large impact...

... Abstract In this paper, we proposed a three-dimensional model for the tension analysis of submarine power cables during laying operations. Both flexural rigidity and axial elasticity were taken into consideration in the form of classical Euler-Bernoulli beam element theory. The governing...

... to possible good economical effect. Installation is one of the crucial marine operations related to the subsea technologies. Right forecast of the weather and wave conditions is the key issue in the planning of installation operation of subsea modules. Limitations of subsea installation related to waves have...
