Operation Of An Articulated Oil Loading Column At The Beryl Field In The North Sea

This paper presents a preliminary study of an analysis of motions and loads of an articulated loading platform (ALP) in regular waves, without a tanker moored to it.For the evaluation of the wave-exciting forces and moment, Newman's linear theory of a slender vertical body of revolution has been employed. axial and lateral shear loads at the universal joint have been calculated within the framework of linearization. The pitching motions of the ALP and theAn attempt has been made to compare the analytical results with available experimental data which have been obtained from a model test in a different environmental condition, i.e., a combination of noncollinear wind, current, and random seas; thus, the experimental response amplitude operators (RAOs) will no longer satisfy the linearity law.

A. Figenschou, Articulated Column Norway A/S w IW130Summary. An articulated tower for drilling and production in the Norwegian Sea in water depths of L,150 ft [350 m] is presented. The main features are production trees it the deck level; a 19,000-ton [17 OOO-Mg]deck payload; limited motions; a steel structure, including main float and latiice; low-stressed mechanical articidation with antitorque device; and controlled bcndlng risers. This extensive study has considered in detail the behavior in extreme condkions, the fatigue of mtin WTIMLWII parts and risers, operating procedures, fabrication, and installation. Generaf results are given concerning behavior, structural design, articulation, bending riser, fabrication, and installation. A fabrication and installation schedule is also given.
