2、k 1862 Copyright 2013 American Bureau of Shipping ABS Plaza 16855 Northchase Drive Houston, TX 77060 USA ii ABSGUIDE FOR THE CLASS NOTATION FOR FIRE-FIGHTING SYSTEMS FOR ON-DECK CARGO AREAS OF CONTAINER CARRIERS .2013 Foreword Foreword Existing fire safety requirements were developed in the late 197
3、0s when carriage of cargo on deck was not a common practice. Since the 1970s, the fire protection provisions and in particular fire-fighting equipment requirements may not have kept pace with the vivid growth of container ships. Considering these issues, this Guide has been developed to enhance the
4、fire-fighting effectiveness for on-deck cargo areas of Container Carriers. This Guide is for the use of designers, builders, owners and operators in the marine industry and specifies the ABS requirements and criteria for obtaining the optional notations FOC (Fire-fighting On-deck Container) or FOC+
5、(Fire-fighting On-deck Container Plus). The requirements are based on the SI units, and the values shown in US (foot-pound-second) units are derived by numerical conversion. This Guide becomes effective on 15 April 2013. Users are advised to check periodically on the ABS website www.eagle.org to ver
6、ify that this version of this Guide is the most current. We welcome your feedback. Comments or suggestions can be sent electronically by email to rsdeagle.org.

12、on FOC+ (Fire-fighting On-deck Container Plus) on Container Carriers classed with ABS. 3 Application Container Carriers provided with an arrangement of a fire piping system and additional fire-fighting equipment in compliance with Section 2 of this Guide will be eligible for the notation FOC. A vess
13、el also in compliance with the enhanced requirements of Section 3 of this Guide will be eligible for the notation FOC+. 5 Definitions 5.1 Bay A Bay is an athwartship block of containers associated with a hatch or hatch cover containing multiple stacks extending longitudinally between two adjacent la
14、shing bridges or lashing stations. 5.3 Container Carrier A Container Carrier is a seagoing vessel specifically designed, constructed, and equipped with the appropriate facilities to carry cargo containers. These containers are stowed in cargo spaces (i.e., in cargo holds below deck) and on hatches a
15、nd cargo areas located on the weather deck. A fully cellular type carries only containers with cell-guides under deck and the necessary fittings and equipment on deck. 5.5 Dangerous Goods Dangerous Goods are the substances, materials, and articles covered by the International Maritime Dangerous Good
16、s Code (IMDG Code). 5.7 Mobile Water Monitors Mobile Water Monitors are large bore water discharge devices of portable or wheeled type, consisting of inlet fitting(s), monitor waterway, swivel fittings, and discharge nozzle. 5.9 On-deck Cargo Area On-deck Cargo Area is the portion of the weather dec
17、k, including hatch covers, arranged with the necessary fittings and equipment to stow a number of container stacks. 5.11 Stack Stack is a single vertical row of containers containing one or more tiers. Also referred to as a row. 5.13 Tier Tier is an indication of the vertical position of a container
18、 in a stack. The first tier is the lowest or bottom-most position in the stack. 5.15 Water Mist Lance A Water Mist Lance consists of a tube with a piercing nozzle which is capable of penetrating a container wall and producing a water mist inside the container when connected to the fire main.
