Break line image
7 September 2006

Notice To All Shipowners, Shipmasters, Ships' Officers, Seamen, Ship Agents, Harbour Masters And All Those Involved In The Securement Of Cargo On Board Ship.
 

The Department of the Marine has been requested by the International Maritime Organisation (I.M.O.) to bring to the attention of all those concerned, the enclosed Draft Guidelines for the Preparation of the Cargo Securing Manual.

The Draft Guidelines have been prepared in accordance with the 1994 amendments to SOLAS Regulations VI/5 and VII/6, and require that cargo units, including containers, shall be loaded, stowed and secured throughout the voyage in accordance with the Cargo Securing Manual, which shall be drawn up to a standard at least equivalent to the Guidelines developed by the I.M.O.

Secretary,
Department of the Marine,
Dublin 2.

20 December, 1996.


 
DRAFT GUIDELINES FOR THE PREPARATION OF THE CARGO SECURING MANUAL


PREAMBLE

In accordance with the International Convention for the Safety of Life at Sea, 1974  (SOLAS) chapters VI and VII and the Code of Safe Practice for Cargo Stowage and Securing, cargo units, including containers, shall be stowed and secured throughout the voyage in accordance with a Cargo Securing Manual approved by the Department of the Marine.

The Cargo Securing Manual is required on all types of ships engaged in the carriage of cargo units as defined in these Guidelines.

The purpose of these Guidelines is to ensure that Cargo Securing Manuals cover all relevant aspects of cargo stowage and securing and to provide a uniform approach to the preparation of Cargo Securing Manuals, their layout and content.  The Department of the Marine may continue to accept Cargo Securing Manuals drafted in accordance with MSC/Circ.385 provided that they satisfy the requirements of these Guidelines.  If necessary, these Manuals should be revised explicitly when the ship is intending to carry containers in a standardized system.

It is important that securing devices meet acceptable functional and strength criteria applicable to the ship and its cargo.  It is also important that the officers on board are aware of the magnitude and direction of the forces involved and the correct application and limitations of the cargo securing devices.  The crew and other persons employed for the securing of cargoes should be instructed in the correct application and use of the cargo securing devices on board the ship.

 

CHAPTER 1 -  GENERAL


1.1 Definitions

 For the purpose of these Guidelines:

 Cargo Units means vehicles (road vehicles, roll trailers, etc.), railway wagons, containers, flats, pallets, portable tanks, intermediate bulk containers (IBC), packaged units, unit loads, other cargo carrying units such as shipping cassettes, cargo entities such as steel coils and heavy cargo items such as locomotives and transformers.  Loading equipment, or any part thereof, transported on the ship, but which is not permanently fixed to the ship, is also considered as a cargo unit.

 Cargo Securing Devices are all fixed and portable devices used to secure and support cargo units.

 Maximum Securing Load (MSL) is a term used to define the allowable load capacity for a device used to secure cargo to a ship.  Safe Working Load (SWL)  may be substituted for MSL for securing purposes, provided this is equal to or exceeds the strength defined by MSL.

 Standardized Cargo means cargo for which the ship is provided with an approved securing system based upon cargo units of specific types.

 Semi-standardized Cargo means cargo for which the ship is provided with a securing system capable of accommodating a limited variety of cargo units, such as vehicles, trailers, etc.

 Non-standardized Cargo means cargo which requires individual stowage and securing arrangements.

 

1.2 General information

 This sub-chapter should contain the following general statements:

   .1 "The guidance given herein should by no means rule out the principles of good seamanship, neither can it replace experience in stowage and securing practice".

 .2 "The information and requirements set forth in this Manual are consistent with the requirements of the vessel's trim and stability booklet, International Load Line Certificate (1966), the hull strength loading manual (if provided) and with the requirements of the International Maritime Dangerous Goods (IMDG) Code (if applicable)".

 .3 "This Cargo Securing Manual specifies arrangements and cargo securing devices provided on board the ship for the correct application to, and the securing of, cargo units, containers, vehicles and other entities, based on transverse, longitudinal and vertical forces which may arise during adverse weather and sea conditions".

 .4 "It is imperative for the safety of the ship and the protection of the cargo and personnel that the securing of the cargo is carried out properly and that only appropriate securing points or fittings should be used for cargo securing".

 

 

 .5 "The cargo securing devices mentioned in this Manual should be applied so as to be suitable and adapted to the quantity, type of packaging, and physical properties of the cargo to be carried.  When new or alternative types of cargo securing devices are introduced, the Cargo Securing Manual should be revised accordingly.  Alternative cargo securing devices introduced should not have less strength than the devices being replaced".

 .6 "There should be a sufficient quantity of reserve cargo securing devices on board the ship".

 .7 "Information on the strength and instructions for the use and maintenance of each specific type of cargo securing devices, where applicable, is provided in this Manual.  The cargo securing devices should be maintained in a satisfactory condition.  Items worn or damaged to such an extent that their quality is impaired should be replaced".
