Where cargo is carried
12、in refrigerated containers of plug-in or integral types which have their own individually mounted refrigeration machinery, hence requiring shipboard electrical power supply and in some cases the cooling water supply for the condensers, and, where fitted, the associated temperature monitoring and con
13、trol system, the Record will give the total number of refrigerated containers onboard, the total design load in kW and the type of temperature monitoring and control system installed. Section 2 of this Guide provides the technical requirements for the optional notation: IRCC-SP xxx/xx (Integral Refr
14、igerated Container Carrier Stowage Positions) for container ships. When requested by the Owner, the systems and arrangements for stowage of integral refrigerated containers may be verified for compliance with the requirements outlined in Section 2 of this Guide. The Class Notation IRCC-SP xxx/xx is
15、supplemented by two figures, the first of which stands for the number of certified integral refrigerated container stowage positions and the second figure for the percentage of containers carrying fruit/chilled cargoes. For example, IRCC-SP 940/35 designates that the ship is capable of the simultane
16、ous carriage of 940 integral refrigerated cargo containers arranged on deck and/or in container holds, and a maximum of 35% of those cargo containers may be loaded with fruit or chilled cargoes. The number of integral refrigerated containers is based on FEU (forty foot equivalent units). Details con
17、cerning other container sizes, stowage positions and special conditions will be stipulated in the Class Record. The requirements in this Guide are in addition to the classification requirements for ships contained in the ABS Rules for Building and Classing Steel Vessels (Steel Vessel Rules). 3 Defin
18、itions Integral Refrigerated Container. A standard container with a self-contained refrigeration system, located within the outer dimensions of the container, which can be driven by electrical power fed from an external power supply. The refrigeration system may be either a “clip-on” or an integral
19、type of cooling unit. Container Plug-in Point. An electrical socket located at each container location on deck and each cell location below the deck which is in accordance with ISO 1496-2. Hold Space. An enclosed space containing refrigerated containers. The containers are restrained within cell gui
20、des. If the ship is “open hatch” type, the hold space refers to the space below the hatch coamings. Container Cell. This is the position of an individual container. It is typically located within a set of vertical cell guides and is normally enclosed by transverse stringers located above and below t
21、he container. 5 References The following Rules, Guides, Codes and Standards are referenced in this Guide: ABS Rules for Building and Classing Steel Vessels (Steel Vessel Rules) ABSGUIDE FOR CARRIAGE OF INTEGRAL REFRIGERATED CONTAINERS ON BOARD SHIPS .2015 1 Section 1 Introduction 7 Vessels Not Built
22、 Under Survey Vessels intended for the carriage of integral refrigerated containers, which have not been constructed under survey by the Surveyors, but which have been subsequently surveyed at the request of the Owners, satisfactorily reported upon by the Surveyor, and which comply with the requirem
23、ents of this Guide, will be distinguished in the Record by the notation, as appropriate, but the mark signifying survey during construction will be omitted. 9 Alternative Designs Design arrangements modified from those which have already been proved suitable in service on board ships are subject to
24、ABSs approval. For these installations and arrangements, ABS may require additional requirements regarding the documentation to be submitted for approval and the extent of testing. If this Class Notation is applied for ships other than container ships, it will be given special consideration. 2 ABSGU

ABSGUIDE FOR CARRIAGE OF INTEGRAL REFRIGERATED CONTAINERS ON BOARD SHIPS .2015 3 Section 2 Technical Requirements for Notation IRCC-SP xxx/xx 3 Design Conditions The container refrigeration units carried on board must be fully functional at ambient t
34、emperatures up to 50C. The design conditions herein are based on the integral refrigerated containers being at their predetermined carrying temperature at the time the containers are loaded on board. The container hold ventilation systems are to be designed based on the size, number and type of refr
35、igerated containers and the types of cargo to be carried. The ventilation system is to be capable of removing the heat from each refrigerated container cell and maintaining the hold temperature at or below the maximum hold temperature. The capacity of supply air is to be calculated based on the foll
36、owing conditions: Ambient air condition: 35C, (95F) Relative Humidity 75% Maximum air temperature in container holds: 45C (113F) Maximum seawater temperature: 32C (90F) Where the vessel is intended to operate in regions where the temperature and the relative humidity other than those mentioned above
37、 are encountered, alternative conditions will be specially considered upon request from the Owners and/or builders. 5 Air Supply for Container Holds 5.1 Air Supply Calculation for Container Holds Designed for the Carriage of Integral Refrigerated Containers using Air-cooled Condensers The below valu
38、es for supply air may be used for guidance: 3100 m3/h per 20-foot integral refrigerated container 4500 m3/h per 40-foot integral refrigerated container Alternatively, the supply air volumetric flow to the container holds may be calculated by applying the formula below. A simultaneous factor need not
39、 be applied. CV= ( )FFCRCWQW+ hvawhere CV= supply air capacity per container stowage position, in m3/s RCW= power demand per integral refrigerated container depending on cargo mix, See Appendix 1, Figures 1 and 2, in kW. FCQ= respiration heat of fruit cargoes per container, in kW FW= power demand of
40、 cargo hold supply air fans per container, in kW va= specific volume of incoming air (see design conditions above), in m3/kg h = change in enthalpy between exhaust air and inlet air, in kJ/kg = h45 h354 ABSGUIDE FOR CARRIAGE OF INTEGRAL REFRIGERATED CONTAINERS ON BOARD SHIPS .2015 Section 2 Technica
41、l Requirements for Notation IRCC-SP xxx/xx 5.3 Air Supply to Container Holds Designed for the Carriage of Integral Refrigerated Containers using Water-cooled Condensers Air supply calculations to the container holds are to be based on the following heat emission values: 1.5 kW per 20-foot integral r
42、efrigerated container 2.1 kW per 40-foot integral refrigerated container Unless stipulated otherwise, a minimum of 8% of the container refrigeration units are considered to operate without water cooling. The below air supply values may be used for guidance: 460 m3/h per 20-foot integral refrigerated
43、 container 700 m3/h per 40-foot integral refrigerated container. 7 Air Ventilation Systems 7.1 Air Ducting and Air Distribution The integral refrigerated containers are to have an air ducting and air distribution system which provides adequate heat dissipation regardless of the loaded condition. Hot
44、 spots are to be avoided and proven by testing, see 3/1.1. Dedicated supply air ducts and fans are to be arranged for each container stack. For the outermost stacks, one supply air duct and fan may serve supply air to the outermost two or three stacks. A maximum of 16 integral refrigerated container
45、s may be served by one supply air fan. For water cooled condenser units (2/5.3 above), the container hold ventilation system may be reduced to two air ducts with fans and the supply air outlets directed to the lower part of the container hold. Supply air to the container holds shall be directed to t
46、he lower part (1/3height) of each container refrigeration unit. For water cooled condenser units (2/5.3 above), air distribution to each individual container need not be provided. Cargo cells containing refrigerated containers are to be provided with sufficient air freshening capability to dissipate
47、 metabolic gas. Where the simultaneous stowage of 8.5-foot and 9.5-foot height containers in holds is desired, the supply air outlets in the holds shall be provided with adjustable openings to provide direct supply air to the lower part of the container refrigeration units irrespective of the stowag
48、e pattern. Use of movable spigot outlets or ducting should be considered. Provisions to minimize the air flow resistance between container refrigeration units and exhaust air outlets of container holds shall be made. Restrictions of air flow caused by interferences (walkways etc.) are to be kept to
49、a minimum. Arrangements allowing the rapid shutdown and closure of the ventilation system to each hold shall be provided in case of fire. 7.3 Air Inlets and Outlets on Deck The arrangement of air inlets and air outlets of cargo hold ventilation systems shall achieve heat dissipation from container holds even in heavy weather. If the air supply inlets must be provided with weathertight closures in accordance with LLC 66/78, protection against water ingress, such as water traps or droplet
