TL;DR: In this paper, the anodes are projections on the surface of a tubular structural member and are fitted on their steel structural members to prevent corrosion on jacket platforms, such as a ship's hull.
Abstract: Offshore structures such as jacket platforms have anodes fitted on their steel structural members to prevent corrosion. The anodes are projections on the surface of a tubular structural member and ...

TL;DR: In this paper , the effects of anodes on the drag coefficients for tubular elements, considering current velocities from 0.25 m/s to 2m/s and three different positions of the anode, back (P1), front (P2), and lateral (P3) to the tubular element, concerning the direction of the current were evaluated.

TL;DR: In this article, the authors present the preliminary theoretical work that has been carried out as part of a programme to establish a rational method for estimating the fluid loading on tubular members with appurtenances.
Abstract: Jacket structures have many sub-sea appurtenances attached to them. For example, a typical jacket structure has hundreds of sacrificial anodes attached to its members. The fluid loading of these structures is calculated using Morison's formula. The force coefficients used in the equation are based on experiments carried out, for the most part, on single cylinders in laboratories in ideal flow. There are very few experimental data available for the fluid loading of cylinders with appurtenances. Moreover, it is not possible to calculate theoretically the loading on such configurations in flows of practical interest using approaches such as the finite element method. However, appurtenances can contribute significantly to the overall loading on a structure. This paper presents the preliminary theoretical work that has been carried out as part of a programme to establish a rational method for estimating the fluid loading on tubular members with appurtenances.
