MOPU refers to a Mobile Offshore Production Unit, which is a floating platform used in offshore drilling operations for oil and gas production. It is designed to support production equipment, with no need for a permanent structure.
Step 1: The MOPU is critical for offshore production in remote locations.
Step 2: It is not related to piping, oil, or process systems, which eliminates options (A), (B), and (D).
Thus, the correct option is (C).
Figure shows an inextensible catenary mooring cable in still water. The submerged weight (per meter length), and the anchor radius are 100 kg/m and 50 m, respectively. If horizontal tension ($T_h$) in the catenary is 1600 kg, the catenary length (AB) is ............. m (rounded to two decimal places).
