Modeling of offshore handling equipment

In engineering practice, depending on the intended use, a wide variety of offshore crane designs are used. Offshore cranes are handling devices installed on floating vessels and production platforms. The most significant feature distinguishing them from their land-based counterparts is the significant base motion caused by sea waves. This article will present examples of modeling various types of offshore cranes. Methods for modeling base motion and the flexibility of selected structural elements will be discussed. Results of numerical simulations will be presented.With the increasing importance of exploiting underwater natural resource deposits, the demand for handling and assembly work performed from the deck of floating vessels is growing. The material handling equipment used for these tasks is called offshore cranes. They are mounted on drilling and production platforms, as well as on floating vessels. Depending on their purpose, they have diverse designs. They can be equipped with a telescopic or fixed boom, lattice or box-type. (…)
