8.1 Application of all available shipboard data related to loading, care and unloading of bulk cargoes (5 hours)

 outlines and describes all relevant information to be appraised prior planning of loading a bulk cargo

 outlines the relevant publications, IMO codes and recommendations that should be referred to prior loading a bulk cargo:

- SOLAS regulation VI/7 and the related code of practice for the safe loading and unloading of bulk carriers (BLU Code)

- International Maritime Solid Bulk Cargoes (IMSBC)

- International Code for the Safe Carriage of Grain in Bulk

- Code of Safe Practice for Cargo Stowage and Securing

 explains the procedure for loading a bulk cargo in detail

 prepares explains that the cargo stowage plans should be prepared after carefully considering and assessing information such as seasonal load line zones, port restrictions, shipboard limits, e.g. draft, cargo capacity, stability, stresses and loading rates

 explains that prior to loading bulk cargo, the shipper should declare characteristics & density, stowage factor, angle of repose, amounts and special properties of the cargo

 explains that in preparing the vessel for a safe planning and cargo stowage, the loading and unloading sequences and other operational matters should be informed well in advance by the charterers / terminal

 explains the content of the loading manual

 explains that the consumption of ship's bunkers, consumption/generation of fresh water, during the voyage should be taken into account when carrying out the stress and displacement calculations

 explains that loading and unloading sequences must consider the loading rate, the de-ballasting capacity and the applicable strength and draught limitations

 plans the loading, care and unloading of bulk cargoes using the ship's approved loading manual and the typical information provided

 describes the action that should be taken if the Master does not believe they have been provided with the required or correct information relating to the cargo to be loaded

 states that it is a statutory requirement of the International Load Line Convention that, noting exemptions, "the Master of every new vessel be supplied with sufficient information, in an approved form, to enable him to arrange for the loading and ballasting of his ship in such a way as to avoid the creation of any unacceptable stresses in the ship's structure" and if the Master feels that he has insufficient information regarding the structural limitations or requires advice on the interpretation of the classification society's structural limitations imposed on his ship, advice should be sought from the ship's classification society

 explains that loading manual is a document which describes:

- the loading conditions on which the design of the ship has been based, including permissible limits of still water bending moments (SWBM) and shear forces (SWSF);

- the results of the calculations of still water bending moments, shear forces and, where applicable, limitations due to torsional loads;

- envelope results and permissible limits of still water bending moments and shear forces (SWBM) in the hold flooded condition as applicable;

- the cargo hold(s) or combination of cargo holds that might be empty at full draught

- if no cargo hold is allowed to be empty at full draught, this should be clearly stated in the loading manual;

and the allowable local loads for the structure (e.g.

hatch covers, decks, double bottom, tank top)

 explains that the loading manual contains typical loading sequences from commencement of cargo loading to reaching full deadweight capacity for homogeneous conditions, relevant part load conditions and alternate hold loading conditions where applicable

 explains that the loading manual contains typical unloading sequences also

 explains that the ship's loading manual is a ship specific document, the data contained therein is only applicable to the ship for which it has been approved

 describes the requirements for the carriage of loading instruments

 describes the typical information that can be obtained from a loading instrument

 explains the certification, testing and use of a loading instrument

 utilises a typical loading instrument to plan and monitor bulk carrier loading, ballast exchange and discharge operations

 , states that the loading computer is an invaluable shipboard calculation tool which assists the ship's cargo officer in:

- planning and controlling cargo and ballasting operations

- quickly calculating and assessing that SWSF and SWBM and the still water torsional moments, where applicable, in any loading or ballast condition will not exceed the specified permissible values during planned loading, unloading and ballast water exchange

- identifying the imposed structural limits which are not to be exceeded

 explains that for each occasion when the ship is loaded or unloaded or ballast water is exchanged at sea, the sequence of the operations should be checked, using the approved loading instrument

 explains that the officer in charge of cargo operation should also refer to the loading manual when planning or controlling cargo operations as the loading instrument is not a substitute for the ship's loading manual

 explains that the ship's loading instrument is a ship specific onboard equipment and the results of the calculations are only applicable to the ship for which it has been approved

 explains that the operation manual of this loading instrument is an essential part of the loading instrument and it should be kept onboard at all times

 states that all the ship's deck officers should familiarise themselves with the operation of the onboard loading instrument

 explains that it is recommended that Master should carry out checks to ascertain the accuracy of the loading instrument against the test cargo loading conditions at regular intervals

 explains that for the loading, unloading and stowage of

solid bulk cargoes, reference should be made to SOLAS regulation VI/7 and the related code of practice for the safe loading and unloading of bulk carriers (BLU Code)

 explains the importance of referring to IMO International Maritime Solid Bulk Cargoes (IMSBC) code prior loading the cargo

 explains the importance of referring the IMO International Code for the Safe Carriage of Grain in Bulk, prior loading grain cargo

 explains the importance of referring to the Code of Safe Practice for Cargo Stowage and Securing prior loading and stowage of bulk cargoes
