The paper shows the role of and the outlooks for the extension of Naftoport Oil Terminal in Gdańsk, Poland as well as the impact of the ongoing development on oil import options and, as a result, on the oil security of the country. The expansion of the oil terminal in Gdańsk is an extremely important project and the largest investment of this type in Poland. Key elements of the development of the terminal are: new transshipment stations and their enhancement, new oil tanks, the construction of the second oil pipeline running to the center of Poland, the development of crude oil technological installations, electricity grid, water and foam networks, sanitary networks, roads, and automation systems. The expansion of Naftoport significantly increases Poland’s oil security as well as import capabilities of the country, ensuring continuous oil supplies to Polish refineries, often at a lower price.

Large steel crude oil tanks constructed in soft foundations are susceptible to various types of settlement deflections. The most common type is planar inclined foundation. In this paper, the FEM is used for the study of deformation characteristic and stress distribution of large steel crude oil tank under the planar inclined foundation approaching to critical value. Results show that deformation characteristic of tank is unevenness; max stress in tank shell occurs in middle-low part of floating roof tank; the ultimate value of large steel crude oil tank under the planar inclined foundation is 0.89m.

In early 1997, Lakehead Pipe Line Company, Inc. (LPL) purchased the Hartsdale Terminal to better serve customers in the Chicago area by providing additional crude oil storage facilities. This terminal is located adjacent to Lakehead’s Griffith, Indiana Terminal and consists of nine crude oil tanks totaling 900,000 barrels of storage capacity. All nine of the Hartsdale tanks were constructed in 1956, are 134 ft. in diameter, and are open top with double deck style floaters. This report describes the integrity analysis of the facility and the corresponding maintenance plan that was developed. The analysis portion of this report describes the inspections that were done on the tanks, covering aspects such as weld spacing; tank settlement; interior and exterior coating failure; tank shell, bottom, and pontoon corrosion; seal wear and performance; roof drain integrity; and other OSHA and API mandates. The resulting maintenance plan is approximately a five-year window and is currently in its first year. The five-year duration was based on issues both operational and financial. A portion of the discussion is focused on the challenge of combining these two components into an overall comprehensive plan. In addition, aspects affecting the maintenance plan such as risk assessment, OSHA and API standards, and budgeting issues are described.

Calcareous or salty soils are the soils which are containing highly dissolved sodium or calcium salts in natural conditions. The dissolution of salts increases with temperature, atmospheric pressure, in addition to the acidity of the dissolves solution. Calcareous soil is stiff and very hard if it is in a dry phase; it becomes collapsible and very week when wetted with water. It is very dangerous for structures when constructing on such soil especially when high stresses are applied on it. Oil tanks or pipes may damage from any reason, and the oil products may leak from these structures to the soil and infiltrate through soil skeleton and may cause leaching to CaCO3 salt particles in some regions in Iraq, as example the Baiji Oil Station or Al-Mosel Dam, CaCO3 percent reaches more than 40%.This study shines the lights about the behavior of Calcareous soil subjected to three oil derivatives (kerosene oil, crude oil, gas oil and a sample wetted with water to make good comparison ,and study effect of addition of this products on the collapsibility.A laboratory model included soil with 70% and 50% CaCO3 compacted to 11 kN/m3. Fix stress system was used which applies 50 kN/m2, the loading frame was manufactured in a way that keeping the weights over footing stable without tilting. Three oil derivatives (Kerosene, Gasoil and crude oil) were used for laboratory model tests; by wetting Calcareous soil with it. One sample was wetted with water for comparison; the settlement was recorded with soaking time at a constant stress level.The results of laboratory model tests shows that the settlements results from specimens soaked with lubricating oil, Gasoil and Kerosene, are much less than the settlements that belong to soaking with water (reduce settlement to about one third) and considered high improvement of such problematic soil by wetting with oil derivatives.
