Based on Table 8 it can be seen that the shortest
fatigue life of the structure is on the deck with the
fatigue life 22 years while at the bottom is 28 years.
It is caused by the deck is the farthest distance from
the neutral axis of the ship.
5 CONCLUSION
According to the analysis and results, this research
can be concluded into:
1. Fatigue life of each case at the bottom is 20
years and 31 years for full cargo and empty
cargo respectively where each load cases are
acceptable according to ABS (20 years).
2. Fatigue life of deck structure has the shortest life
approximately 16 years and 24 years for full
cargo and empty cargo respectively where full
cargo condition is not acceptable according to
ABS (20 years).
3. Both fatigue life of combinations of load cases
at the bottom and at deck are 28 years and 22
years respectively where it is acceptable
according to ABS (20 years) with factor 0.85
represented as the service life of the ship.
