, The California Block Stowage (CBS) Method, dated April 4, 2011. In summary, it states that vessel owners should ensure that: (1) they contact the Managers before agreeing to carry steel cargoes using the CBS method; (2) the CBS method is only used for loading cargo into “box” shaped holds; (3) the stow is loaded out to the sides of the hold to prevent shifting of cargo athwartships; (4) the stow is used only for the trade route for which it was originally intended, and for steel slab cargoes only; (5) the stow is approved by an experienced third party inspector who has been approved in writing by the Managers; and (6) the Managers are consulted in advance as to wordings or amendments to any draft bill of lading, charter party, letter of indemnity, or other relevant document, in order to best protect the vessel owner’s interests. 5.6 Preparation of holds for stowage See Sections 7.2.2.4, 8.3.2(7) and Appendix 2, List of important documents to be kept and maintained. 5.7 Securing and lashing of steel cargoes 5.7.1 Basic principles. In accordance with chapters VI and VII of the SOLAS Convention and the 1991 Code of Safe Practice for Cargo Stowage and Securing (CSS Code), as amended, cargo units (other than solid and liquid bulk cargoes) shall be stowed and secured throughout the voyage in accordance with a Cargo Securing Manual (CSM) that is approved by the vessel’s flag State administration or the classification society of the vessel. 5.7.2 Cargo securing devices. Charterers – in their responsibilities to load, discharge, dunnage, provide the materials for securing and lashing cargo –usually wish to minimize the costs of dunnage materials and lashing and securing materials. Therefore, charterers look to use cost effective securing and lashing materials that are easily obtainable. The Master and the surveyors are encouraged to obtain certificates of the lashing and securing materials from the charterer or their lashing service provider. Some of the standard materials used for securing and lashing include, but are not limited to: American Club: Transport Guidance for Steel Cargoes 52 • flat steel band to lash together such steel products as steel coils (see Figure 5.29); • steel wire rope cable in combination with “Bulldog” or “Crosby” clips, turnbuckles and shackles. For ease of use, normally 0.6 inch (16 mm) (6 x 12) wire rope is what is commonly used for lashing (see Figure 5.30); • removable “weld-on” pad eyes used for securing lashings; • steel chains (see Figure 5.31) and quick acting clamps; • steel stoppers (see Figure 5.3.1); and • nylon stripping band and ratchet tightener (see Figure 5.3.2). 5.7.3 Securing and lashing: general principles. 5.7.3.1 The securing and lashing of a wide variety of steel cargoes is normally left to the well-qualified cargo superintendent, or port captain, and/or stevedore foremen with many years of knowledge and experience. Vessel owners and their Masters should verify whether the methods to be used to secure any steel cargoes are in accordance with the relevant regulations, the CSS Code and their Cargo Securing Manual. 5.7.3.2 Although different securing methods are in use in different ports, these methods may be recognized and approved as “being in compliance” with the CSS Code. Masters are encouraged to obtain written evidence of such approval from the stevedores and lashing gang representatives. 5.7.3.3 In any instance, and depending upon the contractual responsibilities for loading, stowing, dunnaging, securing, lashing and/or discharging cargo, attaching any lashing to the vessel’s side frame directly as seen in Figures 5.33 and 5.34, should be avoided as it could damage the vessel’s structure. 5.7.4 Securing and lashing by cargo type: some basic principles. For certain steel cargoes there are some basic practices that should be considered as follows: 5.7.4.1 Steel coil. Normal lashing material for steel coil is 1 inch (2.5 cm) flat steel band. In dependent of the number of tiers, the general principle applied is that the lashings should secure each of the top tier coils to the two coils in the tier just beneath the top tier. Lashings should be run through the center of the coils. At a minimum, and in common practice, coils are lashed together in groups of threes as seen in Figure 5.29, an example of a basic 5 coil, two-tier configuration. American Club: Transport Guidance for Steel Cargoes 53 If coils are stowed in a single tier, coils are still to be lashed together in groups of threes but only to horizontally adjacent coils except if a key/or locking coil.
