The consideration of welding induced initial
imperfection and residual stress in local element
have degrading effect on the ultimate strength the
ship. However, these effects occur at separate
times in ship’s life; the residual stress and
imperfection are present from the very early stage
of ship’s life, where as the corrosion increases
with passage of time. If an allowance for corrosion
is included in the design, then reduction allowance
for residual stress and imperfection should be
considered.
High compressive stresses due to the hogging
initiated the buckling in the lower parts of the
structure causing a reduction in resistance, and
progressive compressive failure spread upwards
through the structure. The probability of failure in
the hogging case has been significantly high
compared to that in sagging. So it can be
summarised that the VLCC is more prone to
failure in hogging compared to sagging, as
actually happened during its failure.
Attributes of the Prophet Muhammad SAW Praise be to Allah, the Lord of Creations, and Peace and blessings be upon our prophet Muhammad, the faithful and the honest. Oh, Allah, we know nothing but what You teach us. You are the All- Knower, the Wise. Oh Allah, teach us what is good for us, and benefit us from what You taught us, and increase our knowledge. Show us the righteous things as righteous and help us to do them, and show us the bad things as bad and help us to keep away from them. O Allah our Lord, lead us out from the depths of darkness and illusion, unto the lights of erudition and knowledge, and from the muddy shallows of lusts unto the heavens of Your Vicinity. Dear brothers, this is the first part of the introduction to our new series: “Ways of access and signs of acceptance”, inspired by Allah’s Words: "I am only a man like you. It has been inspired to me." [Al Kahf, 110] It is as if in this ayah Allah the ...
