SUMMARY:
For cost reasons the production does not always adhere to the conventional production sequence. Objective of this investigation was the evaluation of three new structural details:
- Part assembly by cogging of crossing webs,
- Integrated bracket in hatch corner,
- Lashing pots in RoRo-decks.
All three structural details show a tendency of root cracking and fatigue life cannot be determined in the design phase. For the first time a possible solution has been tried out on a bracket. The results show that this solution may be successful. However, further knowledge has to be gained with this solution.
