碩士 / 國立臺灣大學 / 造船工程學系 / 85 / Oil tankers are the most appropriate transportation on the
earth, especially in those nations and areas that need
massive oil but lack of it. Due to the critical demand of
environment protection , the Double Hull Tankers recently became
the most common design.
The Double Hull Tankers are absolutely different with the
traditional single hull oil tankers in structural
arrangement . This study will analyze the structural arrangement
and safety of a middle-size ,150 k DWT , double hull tanker in
which there is a center line longitudinal corrugated
water-tight bulkhead.
And then the FEM analysis is carried out to a series of models
which have different depths of double bottom and widths
of double sided shell ,as well as different numbers of
bottom girders and side stringers. And the results are as
follows: The depth of double bottom is
the most important factor of all on the design viewpoint to
a double hull tanker. Deeper the double bottom, less the stress
which the structure in the bottom of the ship has. When
the widths of double sided shell become larger , the
structure near shell gets less stress. Besides, the arrangement
and the numbers of bottom girders and side stringers are
influential in reducing the relative deformation of double
bottom and side shell, respectively.
