The expansion was aimed at allowing the company to be less dependent on tank ship delivery schedules and would ensure that supply of gas to its clients in the country could be achieved without interruptions, while other critical storage vessels were taken out of service for inspection.
Zutari was commissioned to conduct a feasibility study involving the completion of drawings and structural calculations to support Oryx’s application for a building permit to expand the LPG gas storage capacity.
Ultimately, Zutari carried out a full design of the expansion consisting of 3 x 315 m³ mounded bullets, as well as provided specifications for the construction of the plant. The design consisted of the civil and structural, mechanical, process and electrical control. Mounded vessels were selected because of the reduced separation distances associated with this type of vessel, compared to traditional above ground vessels, maximising the additional storage volume for the site.
