... ABSTRACT In this paper, the wake characteristics of the underwater vehicle's mast is simulated by using CFD method based on the RNG k-ε model and VOF model. It can be seen that Kelvin wake is generated due to the moving mast. Then the radar scattering characteristic of the mast along...

... Abstract In this study; we use the monitoring data from the Taiwan Power Company (TPC) meteorology mast (Lu et al.; 2020) to present relationships between the dynamic characteristics of the structure and the site environmental characteristics using a multi-physics survey. First; we compare...

...ABSTRACT ABSTRACT The rapid development of the offshore wind industry has generated increased interest in marine environments. To obtain environmental data pertinent to the operation of an offshore wind farm, a metrology mast was installed by the Taiwan Power Company (TPC). This study focusses...

... Abstract For standalone wireline well interventions on offshore platforms, a number of challenges are faced. As a result, a world first technology in the form of a combined wireline mast and tower system has been developed and successfully implemented to address these safety and operational...

... a conventional crane to suspend the CT injector - is becoming a challenge as the crane and CT equipment spread is already streamlined in efficiency. However, a new piece of equipment has been developed to replace a conventional crane: The Articulating Rotational Mast (ARM). The introduction of the ARM...

... dramatically since the implementation of this policy since a number of wells in the platform need to be shut off while well intervention in the same platform. Re-routing venting sytem to derrick mast is a new technique in South East Sumatra block which can accomodate well intervention using workover rig...

... Computational fluid dynamics (CFD) was used to analyze the flow around a modern research ship to ensure that exhaust gases would not adversely impact the air sampling mast. The air sampling mast measures and records the air to understand the environment that the vessel is operating...

..., construction process and remote sensing system of offshore meteorological mast, which is the first installation case in Korea. INTRODUCTION Recently Korea gives every effort to develop renewable energy sources under the national environmental vision of "Low carbon and Green growth", where government...

... ABSTRACT There are some reports on the excessive vibrations of radar masts, which have caused the failure of the equipment on the radar mast, or lead to strength problems such as the cracks occurring in the brackets at the bottom of the post and the structures under the post. In order...

... In 1997, the Institute for Marine Dynamics (IMD) together with International Submarine Engineering Research Limited (ISER) and Memorial University of Newfoundland (MUN) proposed to design and test a 1/2 scale surface-piercing mast for the DOLPHIN. This new mast was to be designed in such a way...

... ABSTRACT A feasibility study is summarized which analyzed and compared two diverse configurations being considered for a mast which will provide a stable platform for engineering and scientific measurements in a unique deep ocean environment associated with a seamount in the Pacific Ocean...
