Abstract Offshore steel structures are a common investment in oil and gas industries operating in shallow to medium depth seas. These structures have become increasingly popular since the mid-19th century, with a typical design life of 30-50 years. Despite their popularity, the structural integrity of existing offshore structures remains a controversial topic. Environmental loads and material degradation have been identified as significant factors that can compromise the structural integrity of offshore structures. To address this issue, this study aims to investigate the reserved strength capacity of a selected offshore structure located in the Malaysian Seas. The… More >

Abstract A new device is designed to promote the mixing of high-pressure water jets and powders in typical industrial applications. The water and powder mixing devices traditionally used on offshore platforms are detrimentally affected by the geometrical configuration of the water nozzle and the powder spraying pipe, which are parallel, resulting in small intersecting volumes of liquid and powder. By allowing the related jets to intersect, in the present work the optimal horizontal distance, vertical distance and intersection angle are determined through a parametric investigation. It is also shown that such values change if the number More >
