Section 1 General

1.1 Application

1.1.1 The re-assessment procedures given in Ch 2, 2 Re-assessment of vertically corrugated transverse watertight bulkheads for the vertically corrugated transverse watertight bulkhead between cargo holds No. 1 and No. 2, for bulk carriers of length, L, greater than or equal to 150 m, carrying solid bulk cargoes having a density of 1,78 t/m3 or above, with single deck, topside tanks and hopper tanks and fitted with vertically corrugated transverse watertight bulkheads between cargo holds No. 1 and 2 are to be applied where:

  • the foremost hold is bounded by the side shell only, for ships which were contracted for construction prior to 1 July 1998 and have not been constructed in compliance with Pt 4, Ch 7, 10 Bulkheads of Notice No.2 to the 1996 Rules and Regulations for the Classification of Ships (hereinafter referred to as the Rules for Ships), or subsequent editions, see Ch 4 Appendix 1;
  • the foremost hold is double side skin construction of less than 760 mm breadth measured perpendicular to the side shell in ships, the keels of which were laid, or which were at a similar stage of construction, before 1 July 1999 and have not been constructed in compliance with Pt 4, Ch 7, 10 Bulkheads of Notice No.2 to the 1998 Rules for Ships, or subsequent editions, see Ch 5 Appendix 2.

1.1.2 The re-assessment procedures given in Ch 2, 3 Re-assessment of double bottom structure for the double bottom in way of cargo hold No. 1, of bulk carriers of length, L, greater than or equal to 150 m, carrying solid bulk cargoes having a density of 1,78 t/m3 or above, with single deck, topside tanks and hoper tanks, are to be applied where:

1.1.3 Application of Ch 2, 2 Re-assessment of vertically corrugated transverse watertight bulkheads to other cargo hold transverse watertight bulkheads and double bottoms is optional. See Ch 2, 1.2 Class notations.

1.1.4 The requirements given in Ch 2, 4.1 Loading Instrument for the supply of Loading Instruments to bulk carriers of length, L, greater than or equal to 150 m, which were contracted for construction before 1 July 1998, are to be complied with by 1 January 1999 or the date of entry of the ship into service, whichever is later.

1.1.5 The requirements given in Ch 2, 4.2 Loading Manual for the supply of Loading Manuals to bulk carriers of length, L, greater than or equal to 150 m, where one or more cargo holds are bounded by the side shell only, which were contracted for construction before 1 July 1998, are to be complied with by 1 July 1999 or the date of entry of the ship into service, whichever is later.

1.1.6 The procedures for the re-assessment of side shell frames and brackets of cargo holds bounded by a single side shell, given in Ch 2, 5 Re-assessment of side shell frames and brackets, are to be applied to bulk carriers constructed with single deck, topside tanks and hopper tanks in cargo spaces carrying dry cargo in bulk, which were not built in accordance with Pt 4, Ch 7, 6.2 Transverse stiffening of Notice No.2 to the 1996 Rules for Ships (see Ch 7 Appendix 4 ), or subsequent editions, in accordance with the following schedule:

  • For ships which will be 15 years of age or more on 1 January 2004 by the due date of the first intermediate or Special Survey after that date.
  • For ships which will be 10 years of age or more on 1 January 2004 by the due date of the first Special Survey after that date.
  • For ships which will be less than 10 years of age on 1 January 2004 by the date on which the ship reaches 10 years of age.

Completion prior to 1 January 2004 of an intermediate or Special Survey with a due date after 1 January 2004 cannot be used to postpone compliance. However, completion prior to 1 January 2004 of an intermediate survey the window for which straddles 1 January 2004 can be accepted. In the case a vessel as defined here does not satisfy the definition in one or more holds, the requirements do not apply to those individual holds.

1.1.7 The requirements given in Section 7 apply to all bulk carriers which were not built in accordance with Pt 4, Ch 7, 12 Steel hatch covers of the Rules for Ships and are for steel hatch cover securing devices and stoppers for cargo hold hatchways No. 1 and No. 2 which are wholly or partially within 0,25L of the fore perpendicular, excepting pontoon type hatch covers, and are to be complied with according to the schedule given in Ch 2, 1.1 Application 1.1.6.

1.2 Class notations

1.2.1 Where the vertically corrugated transverse watertight bulkhead between holds 1 and 2 or the double bottom in way of hold 1 fail to meet the requirements of Ch 2, 2 Re-assessment of vertically corrugated transverse watertight bulkheads and Ch 2, 3 Re-assessment of double bottom structure, strengthening and/or deadweight restrictions will be required. Compliance with these Rules will be identified by the class notation ESN (Enhanced Survivability Notation) assigned as follows:

  1. ESN-Hold 1. This notation will be assigned to a ship that has been assessed for flooding of No. 1 hold and complies with or has been strengthened to comply with the requirements of these Rules.

  2. ESN-Hold 1 with Loading Restrictions. This notation will be assigned to a ship that has been assessed for flooding of the No.1 hold and complies with the requirements of these Rules by virtue of imposed loading restrictions.

1.2.2 Where a Shipowner opts to examine all holds, the assigned notations will be as follows:

  1. ESN-All Holds. This notation will be assigned to a ship that has been assessed for the flooding of all holds and complies with or has been strengthened to comply with the requirements of these Rules.

  2. ESN-All Holds with Loading Restrictions in Hold(s) No. ........ This notation will be assigned to a ship that has been assessed for the flooding of all holds and complies with these Rules by virtue of imposed loading restrictions.

1.3 Damage Stability

1.3.1 Single side skin bulk carriers are required to be re-assessed in accordance with Ch 2, 2 Re-assessment of vertically corrugated transverse watertight bulkheads and Ch 2, 3 Re-assessment of double bottom structure, when loaded to the summer load line and are to be able to withstand flooding of the foremost cargo hold in all loading conditions and remain afloat in a satisfactory condition of equilibrium, as specified in SOLAS Chapter XII, Regulation 4 - Damage stability requirements applicable to bulk carriers in accordance with the following schedule:.

  • For ships which were 20 years of age or more on 1 July 1998, by the due date of the first Intermediate Survey or the due date of the first Special Survey to be held after 1 July 1998, whichever comes first;
  • For ships which were 15 years of age or more, but less than 20 years of age on 1 July 1998, by the due date of the first Special Survey, to be held after 1 July 1998, but not later than 1 July 2002;
  • For ships which were 10 years of age or more but less than 15 years of age on 1 July 1998, by the due date of the first Intermediate Survey, or the due date of the first Special Survey to be held after the date on which the ship reaches 15 years of age but not later than the date on which the ship reaches 17 years of age;
  • For ships which were five years of age or more but less than 10 years of age on 1 July 1998, by the due date, after 1 July 2003, of the first Intermediate Survey or the first Special Survey after the date on which the ship reaches 10 years of age, whichever occurs first;
  • For ships which were less than five years of age on 1 July 1998, by the date on which the ship reaches 10 years of age.

Completion prior to 1 July 2003 of an Intermediate Survey or Special Survey with a due date after 1 July 2003 cannot be used to postpone compliance. However, completion prior to 1 July 2003 of an Intermediate Survey, the window for which straddles 1 July 2003, can be accepted.

1.3.2 A ship which has been built with an insufficient number of transverse watertight bulkheads to satisfy the requirements of Ch 2, 1.3 Damage Stability 1.3.1 may be exempted from the application of Ch 2, 1.3 Damage Stability 1.3.1 and of Ch 2, 2 Re-assessment of vertically corrugated transverse watertight bulkheads and Ch 2, 3 Re-assessment of double bottom structure, provided that the ship fulfils the requirements of SOLAS Chapter XII, Regulation 9 - Requirements for bulk carriers not being capable of complying with regulation 4.3 due to the design configuration of their cargo holds.

1.3.3 Where a Shipowner opts to examine all holds, the ship is to be able to withstand flooding of any one cargo hold in all loading conditions and remain afloat in a satisfactory condition of equilibrium as specified in SOLAS Chapter XII, Regulation 4 - Damage stability requirements applicable to bulk carriers.
