Performance of Offshore Steel Jacket Platforms under Near-source Ground Motion Type Pulses
Abstract: Behaviour of jacket type offshore structures under ordinary ground excitations has already been addressed by a number of researchers. However, their performance under near-source ground excitations has not been particularly addressed in the literature. Records from recent earthquakes, such as the Kobe Japan (1995) and Chi-Chi Taiwan (1999), have revealed that the dynamic excitations in near-source are dominated by a large, narrow band and long period pulse caused by rupture …

Fatigue Assessment of Longitudinal Stiffener End Connections for Ageing Tankers
Abstract: Abstract The world tanker fleet is ageing. In this situation it is essential to ensure that the transportation of oil and gas is carried out by quality vessels. This is possible with old tankers as long as their condition can be properly assessed. Since the 80’s relatively few new-buildings have been ordered and this has opened for operation of tankers up to 30 years of age. Ship and offshore structures …

Fatigue Assessment of Flare Foundations on FPSO Structure
Abstract: This paper addresses the fatigue analysis results of the new-built FPSO’s flare tower foundations and associated the hull which is supporting the four cylindrical legs of the flare. Flare foundation is checked for fatigue resistance both in “towing” and “on site” conditions. The fatigue design of the flare supporting structure is to take into account the inertia loads due to wave motions in towing and on site, but also the …

Modelling and Structural Analysis of Ice Strengthened Vessel
Abstract: Abstract In this paper, one global and one local FE-model are developed in order to calculate the response of ice loading on an ice strengthened 100.000 DWT oil carrier. A global analysis is performed by applying loads in two different areas in the bow region. The deformations of the global model are used as boundary conditions in the analysis of the local model. In each of the two areas, the …

Small-Scale Model Study on the Load-Deflection Characteristics of Single Piles under Static Lateral Load
Abstract: The capacity of a certain mathematical model to mimic a behavior occurring on a larger scale often concerns engineers. To evaluate a particular structure's safety factor, model uncertainty is an important consideration. Piles have been widely used to support axial and lateral loads for a wide range of structures, including high-rise buildings, transmission towers, power plants, offshore structures, highway and railway structures. Many transmission towers, high-rise buildings, highway and railway …

Interpretive Structural Modeling for Water Supply Service in India
Abstract: This paper develops a systematic assessment of the sustainability of water services provided to the consumers in rural, urban and municipality area in India and finds the interrelation between different dimensions by interpretive structural modeling. Given the conflicting preferences among the stakeholders and the incomplete, uncertain and contradictory understanding about water service by the Indian consumers, it is recognized that managing water resources sustainably is a wicked problem. In India …

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 …

Application of Thermal Spray Coatings for Corrosion Control in Oil and Gas Refineries
Abstract: In today’s context, Thermal Spray Coating (TSC) has emerged as a highly durable and reliable alternative to traditional Hot-Dip Galvanizing (HDG). It is increasingly being adopted for both new and existing industrial structures due to its long-lasting protection—often exceeding 25 years—while requiring little to no maintenance. Unlike HDG, which cannot be welded on-site and often poses challenges with repair methods such as liquid coating or cold spray, TSC offers greater …

A Review on Strength of Concrete in Marine Structures
Abstract: Several billion tons of water is annually used as mixing, curing and cleaning around the world, in concrete industry. As there is a scarcity of fresh drinkable water around the world; so there is a need to save fresh water and hence possibilities of using seawater as mixing as well as curing water should be investigated seriously. Additionally, if use of seawater as concrete material is permitted, it will be …
