Oil & Gas Platform Structural Detailing Service


There are many types of offshore platforms, including jack-up, tension leg, semisubmersible, and submersible. This paper focuses on the design and engineering of the topside and jacket structure for an oil & gas platform .The design of offshore platforms is a complex task due to several factors. For example, the environmental conditions at the platform site are different from that of land-based structures, and wind loads and wave loads may be significant. A typical offshore oil & gas platform is designed with a jacket structure which consists of a skeleton frame (the jacket) surrounding the topside structure. The design of the topside and jacket structures for an oil & gas platform is a complicated one due to the many other factors that must be considered, such as: The topside and jacket are designed to withstand the forces generated due to wind, waves, earthquakes and other forces. They have the following functions:-Supporting structure of the helmet-Helmet suspension system-Optical performance.

Oil and gas platforms are designed to withstand the harsh environment of offshore oil and gas exploration, production, and drilling. The topside is an offshore platform that contains all the equipment for drilling, production, storage and offloading of oil or gas. The jacket is a structure that supports the topside.

Oil & Gas Platform Structural Design:

The structure design for an offshore platform typically includes a jacket with its associated topsides. This is because the jacket provides stability for the platform while also protecting it from waves. The jackets are made up of three primary structural components: columns, deck beams and stiffeners. These components are built with steel plates welded together to form a rigid framework. A jacket also Detail drawings includes topside equipment, such as docks. The columns are placed at equal intervals around the periphery of the jacket and are attached to the deck beams and stiffeners. The top of each column is attached to a plate at the top of a floor beam, which in turn is bolted to a plate on the deck beam.

Offshore platforms are the heart of a petroleum production system. They are the base for all other operations on the water. The offshore platform is designed to withstand harsh weather conditions and provide a stable foundation for production equipment.

The offshore platform is built with two major structures, the topside and jacket structure. The topside is used as an office space, while the jacket structure provides a stable foundation for drilling equipment. The structural design of these two structures must be carefully considered to ensure they can withstand any environmental or operational hazards that may arise in their lifetime.
