TECHNICAL REQUIREMENTS FOR FIBERGLASS HULLS IN OFFSHORE OIL AND GAS OPERATIONS

Abstract

This article notes the operation of auxiliary vessels in harsh, aggressive offshore oil and gas field conditions. These vessels transport the necessary equipment and tools, etc. to the oil and gas field trestles. That is, there is wear and tear and ageing of hull structures after a long period of time. As a rule, ship hull structures are made of steel and metals of a certain grade. The aggressive sea water causes corrosion which leads to hull deterioration and gradual destruction. To prevent corrosion, fiberglass material or fiberglass plastics are used. This material is known to be the basic construction material created by scientists and technologists. Fiberglass material, as described in the article, must meet the technical requirements for the operation of auxiliary vessels with hulls made of this material. It is noted that fiberglass material is used in order to save metal and steel. Which is of scientific and practical importance. This material is also used in other areas of engineering and technology. The weight of the material is relatively small compared to metal and steel. According to the technical requirements for the operation of auxiliary vessels, an example is given for increasing the strength of fiberglass material by treatment with a reinforcing agent. The hulls of vessels when transporting the necessary equipment and tools to the trestles of offshore oil and gas fields, are subjected to shock loads of sea waves, as well as the load from the weight of the transported cargo. Consequently, the article notes that hull structures made of fiberglass material, can be one or two or three layers. This gives the ship's hull shock resistance. In this case, the requirement for durability during operation of auxiliary vessels is observed. The scheme of these hulls in cross-sectional view is given. It is noted that repair of hulls made of fiberglass material is easier in comparison with other materials. Deck coating is described, which increases the strength of the running surface of the deck and ensures its durability and carrying capacity. In general, the article describes all the technical requirements for fiberglass hulls and their advantages over materials like metals and steel. It is said that the operation of auxiliary vessels with fiberglass hulls in adverse oil and gas field conditions with the technical requirements for these hulls described in the article, will be of high quality and economical.
