Finite element method analysis of pipe material temperature changes influence on line expansion loops in hydraulic installations on modern tankers

Abstract

Finite element method analysis of main lines of hydraulic central loading system installation expansion loops mounted on product and chemical tankers has been presented in the paper. The axial forces problem in installations mounted along the ship?s open decks executed from hull deformations on waves and thermal stresses is given. Use of ?U? type expansion loops is described. Results of forces in anchor points and stresses of Mises due to expansion loop deformations are shown. Calculations were made by ABAQUS Ver.6.7 FEM computer program.
