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.
Khasiat Fadhilat (Isnad) Doa Haikal - Majmu' Syarif
Inilah khasiat fadhilat Doa Haikal yakni 7 doa drp no. 1 sampai no. 7 & sampai "Qul a'uuzubirabbinnaas" bahawasanya adalah diriwayatkan oleh Nabi kita Muhammad SAW pd suatu hari sedang Nabi kita SAW duduk di dalam Masjid Madinah maka Jibrail AS pun datang membawa firman ujarnya, "Ya Rasulullah SAW salam Allah SWT pd tuan hamba & firmannya, 'Hai kekasihku adapun doa ini yakni 7 doa ini dihantarkan Tuhan pd tuan hamba maka barangsiapa tiada percaya akan doa ini kafirlah ia & barangsiapa membaca dia atau menyimpan dia maka Allah SWT melepaskan dia & ibubapanya drpd api neraka ya Muhammad barangsiapa menaruh doa ini di dlm rumahnya maka tiada boleh masuk jin & syaitan ke dlm rumahnya itu ya Muhammad barangsiapa suratkan doa ini & dipakai diperbuat tangkal nescaya terlepaslah ia drpd azab sengsara & wabak & duduk itu dlm aman & lagi barangsiapa menaruh doa ini sentiasalah ia dihormati orang & termulialah ia pd orang banyak &
