Engineering Office Odebrecht Engenharia Industrial Construction Period 06/2013 - 07/2016 Paraguaçu Unit is building six drillships for Sete Brasil. The equipment will be used in the exploration of pre-salt deposits, at a depth of three thousand meters. Four of these ships - Ondina, Pituba, Boipeba and Interlagos - are being built in partnership with Odebrecht Óleo e Gás. The other two - Itapema and Comandatuba - involve another partnership: Etesco/OAS. The total value of the contract is around US$ 4.8 billion. Due to the upside-down construction methodology adopted, the Megablocks structure needed to be verified during the upending operation. This analysis was performed in SCIA Engineer by means of a Finite Element model. The Megablocks structure was modeled with shell elements (2D) and the cables used in the lifting arrangement were modeled with frame elements (1D). The load during the upending operation is the self-weight of Megablocks, approx. 100 tons, based on information given by the architect. Yielding and linear buckling, based on static linear elastic calculation, have been verified. From these analyzes, local reinforcements were added, because of high stresses in the lifting system. These reinforcements were developed and verified with the help of SCIA Engineer, ensuring safe operation.
