Offshore lifting analysis object weights below 50T
Master's thesis in Offshore structural engineering ; This thesis consists of two main objectives: Learning to use NORSOK-R002 and comparing it with Aker Solutions former work instruction manual A237; and conducting a case study on the main frame of the C05 east balcony for the Gina Krog project. The main task in the case study was to maintain proper weight structure with sufficient capacity and strength in respect to transportation, installation and operation. Apart from that, the design analysis and optimization of this structure were undertaken to create a structure that has a high element of safety with respect to life, environment and economic risk. NORSOK R-002 was used for hand calculations of lifting accessories used in the case study. During modeling, design analysis and optimization of the C05 balcony the following software tools were learned and used: STAAD.pro. Mathcad. In addition, the following topics were considered: Evaluation and use of relevant rules and standards for offshore construction. Optimizing the main frame and selection of steel profiles to achieve optimum design with respect to weight, strength and costs for transport, lifting, installation and operation. Using the load and resistance factor design (LRFD) method for checks and control. Local calculation of joints, beams, lifting lug, slings, master links, forerunners, bolts, welds and other lifting accessories. The structural design and analysis was performed considering the lifting operation as basic. However, other stages had to be considered in order to create an optimal structure. During the case study, NORSOK R-002 and Aker work instruction manual A237 were both used for full comprehension and comparison. In an issues chapter below, factors are evaluated and compared.
