Paper presented at the The First ISOPE European Offshore Mechanics Symposium, August 20–22, 1990
Paper Number: ISOPE-E-90-064
... sheets pushing on a rigid structure of the "Monopod" type is defined by formulas in which the values of h and R are accepted, as a rule, as the maximum values with a sufficient probability of occurence for the period considered [4, 9]. In case of interaction between a group of pile and on ice field...

... ABSTRACT The paper describes a practical method of solving the beam-column problem of a conductor with casings and production tubing between the drill floor and the sea floor. With a recognized formula for the interaction between axial force and bending moment as the basis, it is explained how...

... of fleXIble pipes. Degradation of risers may result from wear of the tensile armor wires as a result of slip during flexure. Wellstream has derived a formula for the magnitude of slip of the wires across each other during dynamiC bending, and a cnterion for a contact pressure that will prevent slip...

...-field' and 'near-field' methods. These two methods should, in theory, produce the same results. Any discrepancies were due to numerical errors, which affected the two procedures in different ways. The method was known to be susceptible to numerical errors : a) because the mathematical formulae contain...
