What are regulations for Bulk carrier construction as per SOLAS ?

Written by Amit Sharma

Construction Details of bulk carrier are as follow :

  • These ships have large clear holds with no ’tween decks. This facilitates fast loading & discharging.
  • Hatches are capable of being covered with weather tight covers.
  • Engines are usually placed aft.
  • Topside tanks (Upper Hoppers) are provided as shown in sketch, to enable water ballast to be carried high up & reduce GM.
  • This may be required when carrying heavy cargoes, such as ore in the holds.
  • A deep tank is usually not fitted, although one of the middle cargo holds may be usable for taking in ballast (Heavy Ballast Condition).
  • In the type shown in the sketch, the sloping side tanks at the bilge form a ‘hopper’(Lower Hopper) which assists in handling of bulk cargo.
  • The sloping upper & lower hoppers make the bulk carrier holds self trimming for carriage of cargoes such as grain.
  • The height of Hatch coamings on freeboard deck, raised quarter deck, or within one-quarter of the ship’s length from the stem on superstructure decks is to be 600 mm, where they are exposed to the weather. Abaft one-quarter of the length from the stem, the height is to be 450mm.
  • Framing except in Large Bulk Carriers is composite type.
  • Framing under deck is Longitudinal type.
  • The side plating where longitudinal stresses are less, is Transversely framed.
  • Framing in Double bottom is longitudinal type.
  • The longitudinals are supported by Plate floors not more than 3.7 metres apart.
