Section 5 Hatch Side Girders

501. Deep coamings on decks

Where deep coamings are provided on decks as in the case of hatchway on weather deck, the hori- zontal coaming stiffener and the coaming up to its stiffener may be included in the calculation of the section modules, subject to the approval by the Society.

502. Brackets of hatch side girders not extended to bulkheads

Where hatch side girders do not extend to the bulkheads, brackets extending for at least two frame spaces beyond the ends of hatchways are to be provided.

502. Strength continuity

At hatchway corners, the face plates of hatch coamings and longitudinal deck girders or their ex- tension parts and the face plates on both sides of hatch end girders are to be effectively connected so as to maintain the strength continuity.
