Construction Planning of an Offshore Petroleum Platform 1
Professor Kabir Sadeghi
The study evaluated the project life cycle for the construction of a fixed petroleum platform which comprises of the planning, design, fabrication, load-out, transportation, installation and commissioning phases. The project life cycle, like several offshore structures located in open waters and exposed to severe forces must be planned in great details for a successful execution. It is therefore necessary to study and gather all necessary information on the construction of a platform with the objective of creating a client, consultant and contractor's work breakdown structure (WBS) template in a project planning software. The results of this study eventually serve as a guide which can be adjusted to suit the planning and management for the construction of a fixed petroleum platform depending on the soil characteristics, environmental and operational parameters. An oil platform is a large structure used to house workers and machinery needed to drill and then produce oil and natural gas in the ocean (Wikipedia 2007). There are different types of petroleum platforms and each of these types is chosen primarily due to water depth considerations, and secondarily due to the intended service and quantity of deck equipment necessary to perform its service. To develop a WBS for the construction of a fixed jacket petroleum platform, the following issues were investigated: 1) Planning: It takes into account operational considerations (i.e. the function, location, and orientation of the platform) and environmental considerations (including winds, tides, currents, ice, shallow gases, earthquakes and marine growth) (Sadeghi 2001), 2) Design: It analyzes the dead loads (i.e. weights of the platform structure and any permanent equipment and appurtenant structures which do not change with the mode of operation), live loads (loads imposed on the platform during its use and which may change either during a mode of operation or from one mode of operation to another) and environmental loads (loads imposed on the platform by natural phenomena including wind, current, wave, earthquake, snow, ice and earth movement),

Review on Fixed and Floating Offshore Structures. Part II: Sustainable Design Approaches and Project Management
Chiemela Victor Amaechi
Offshore structures exist in a variety of forms, and they are used for a variety of functions in varied sea depths. These structures are tailored for certain environments and sea depths. Different actions for suitable equipment selection, platform type design, and drilling/production processes are required for the applications of these offshore structures, as given in Part I. This paper is the second part, which outlines various processes, loads, design approaches and project management of offshore platforms. To achieve these, proper planning must be conducted for lifting, transportation, installation, design, fabrication, and commissioning of these offshore platforms. Some historical developments of some offshore structures are presented, and some project planning routines are undertaken in this research. The ultimate goal is to provide a general overview of the many processes of offshore platform design, construction, loadout, transportation, and installation. Some discussions on ...

Offshore petroleum rigs/platforms: An overview of analysis, design, construction and installation
Mahdy Raslan
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 havi...
Significant Guidance for Design and Construction of Marine and Offshore Structures
Professor Kabir Sadeghi
Marine and offshore structures are constructed worldwide for a variety of functions and in a variety of water depths, and environmental conditions. Shore protection facilities, ports, harbors and offshore petroleum platforms are important infrastructures which have big impacts on the economy level and industrial progress of countries. Selection of type of platform and also right planning, design, fabrication, transportation and installation of marine and offshore structures, considering the water depth and environment conditions are very important. In this paper an overview of coast, ports and offshore structures engineering is presented. The paper covers mainly design and construction of jetties, harbor and fixed template offshore platforms. The overall objective of this paper is to provide a general understanding of different stages of design, construction, load-out, transportation and installation of marine and offshore structures.

An Overview of Design, Analysis, Construction and Installation of Offshore Petroleum Platforms Suitable for Cyprus Oil/Gas Fields
khairul farihin
Offshore structures are used worldwide for a variety of functions and in a variety of water depths, and environments. Since right selection of equipment, types of platforms and method of drilling and also right planning, design, fabrication, transportation, installation and commissioning of petroleum platforms, considering the water depth and environment conditions are very important, this paper will present a general overview of these aspects. This paper reviews the fundamentals behind all types of offshore structures (fixed or floating) and, in the case of fixed platforms, will cover applications of these principles. The overall objective is to provide a general understanding of different stages of design, construction, loadout, transportation and installation of offshore platforms. Finally, for different seawater depths, in which the Cyprus platforms are intended to be installed, suitable kinds of offshore platforms are proposed. Introduction Offshore platforms have many uses including oil exploration and production, navigation, ship loading and unloading, and to support bridges and causeways. Offshore oil production is one of the most visible of these applications and represents a significant challenge to the design engineer. These offshore structures must function safely for design lifetimes of twenty-five years or more and are subject to very harsh marine environments. Some important design considerations are peak loads created by hurricane wind and waves, fatigue loads generated by waves over the platform lifetime and the motion of the platform. The platforms are sometimes subjected to strong currents which create loads on the mooring system and can induce vortex shedding.

A Comprehensive Review on Design, Monitoring, and Failure in Fixed Offshore Platforms
kazem reza kashyzadeh
Offshore platforms have had diverse applications in the marine industry, for example, oil or gas platforms can provide facilities to store the oil and gas before transport those to refineries. Offshore wind turbines are another well-known use of the offshore platform for generating power. As platforms encounter various strong forces from water and wind currents, the materials used for these structures are mainly steel or concrete. These platforms are classified into different types, according to the depth of water and their applications. In addition, offshore platforms, as artificial reefs may be used for decades at different marine conditions. Consequently, their design and maintenance are very important, otherwise, they can cause irreparable damage to the environment. This paper presents the latest and most significant design and monitoring methods, such as the optimal probabilistic seismic demand model, multi-objective optimization, dynamic response assessment, robust fault-toler...
