Abstract
Jacket platforms are one of the most important and regularly used types of offshore structures for oil and gas extraction that have a big impact on the economy of the countries. In this paper, all aspects including design, analysis, construction and installing of the jacket type offshore structure, are summarized and classified. This type of structure is one of the specified platforms for shallow water, and for long term service, it also has the ability to carry large deck loads. This paper aims to present general guidance about the planning, design and construction of offshore jacket (template) platforms. Jacket platforms are fixed type platforms which are attached to the seabed using piles which provide stability against the wind, wave and current loads. Also, this type of offshore platform has a high initial and maintenance cost because of its exposure to corrosion, and cannot be reused after the end of its service period. Jacket platforms are most suitable for shallow water having no better alternative while it has the cost disadvantage for deep water.
Highlights
Offshore structures play a significant role in the economy of many countries, as offshore structures are mainly drilling platformers which used to extract oil and gas from the bottom of the seabed
Jacket platform is a kind of offshore structure, made of lots of steel cylindrical members with different diameter arranged in an oblique condition relative to the seabed (Zhang et al, 2006)
All aspects related to the construction of the jacket type offshore platform are summarized
Summary
Offshore structures play a significant role in the economy of many countries, as offshore structures are mainly drilling platformers which used to extract oil and gas from the bottom of the seabed. This study gives an overview of the offshore jacket platform's characteristics, and investigate the stage of its design, construction and installation. "Jacket type platforms are one of the most important and common types of offshore structures, and it plays an important role in drilling and exploring the oil" (Zhang et al, 2012). Where the water is shallow, the use of this type of platform is more compatible and economical to the use in depths generally ranging between 10 m to 200 m (Xiaojie et al, 2019). Sadeghi (2008) gives a detailed guide for the design and construction of offshore platforms while focusing on the jacket type platforms
