Use of Simple Scientific Principles in Rural Areas for Common Utility
Abstract: Archimedes principle describes the laws of a floating body, be it a country boat or an ocean going ship. Based on such principle and common laws of forces defined by Newton’s laws for motion, the stability equations of a floating body has been developed. Some of the Indian villages, mostly in northern India, are inundated with many rivers and canals which are mostly used for economic activities like fishing, irrigation …

Effect of Moonpool on Drillship Motions
Abstract: A moonpool is meant for access to the underwater part from the onboard ship. It is a vertical opening along with the depth having an effect on the performance of the floating platform. The water motion inside the moonpool of a drillship is mainly in horizontal sloshing mode and vertical piston mode. This water motion in horizontal or in vertical mode mainly depends on the cross-section of the moonpool, encountering …

Comparative Study on Fatigue Analysis Methods using Turret-moored FPSO Model
Abstract: Abstract Floating structures are prone to fatigue due to high cyclic loads mainly caused by waves and changing loading conditions. Therefore, fatigue is an important criterion during design. The fatigue life is dependent upon factors such as global and local design, workmanship during construction, maintenance, corrosion protection, and trade and load history. Different approaches are applied to the fatigue strength assessment. Longitudinal stiffener end connections are also important structural elements …

Concrete Oil and Gas Platforms in Offshore Marine Environment: A Review
Abstract: Abstract Offshore concrete structures have been successfully in use since 1973. Since then, 47 major concrete offshore structures were built worldwide. They were mostly used in the petroleum industry as drilling, extraction or storage units for crude oil or natural gas. Generally, offshore concrete structures are classified into fixed and floating structures. Fixed structures are mostly built as concrete gravity based structures where the loads are directly transferred through concrete …

Consideration of Collision Damage in FPSO Structural Design
Abstract: AbstractA collision event may be catastrophic for an offshore facility or a floating production, storage and offloading unit (FPSO). Depending on the size and speed of the impacting ship, anything from damage to hull rupture, oil pollution, flooding, loss of buoyancy, capsizing, and sinking may occur. Supply vessels and tankers frequently visit the FPSO to transport consumables and chemicals and, consequently, there is a risk of collision between two structures. …
