This International Standard specifies the functional requirements for bridge configuration, bridge arrangement, bridge workstations and bridge environment. Guidelines have been drawn up for the methods and solutions to meet the functional requirements. The requirements in this International Standard apply to all bridge functions. The purpose of this International Standard is to assist the operator(s) and pilot by providing a workplace that is conducive to safe and effective operation. It also aims to specify bridge requirements, which will secure safe and efficient operation of the ship berth-to-berth regardless of the watchkeeping arrangement in place at a particular time. This International Standard should be used in support of the aims in SOLAS Chapter V Regulation 15. Requirements and guidance on the human element aspects of the bridge system (e.g. training, procedures) are not given. However, for safe and effective watchkeeping, these aspects will need to be addressed. The main use of this International Standard will be for designing ships’ bridges. This International Standard will also be useful to — specifiers and procurers of ships and bridge equipment, — operators, and — owners for ensuring that changes made to the bridge through the life of a ship continue to conform to these requirements. This International Standard is applicable to seagoing ships. Where there are physical limitations in applying this International Standard, i.e. to small ships or to ships of unusual design, the general functional requirements still apply. Annex A of this International Standard applies to high speed craft. This International Standard does not supersede performance standards for bridge equipment. Users of this International Standard should note that while attempting to implement its requirements, they should ensure compliance with such statutory requirements, rules and regulations as may be applicable to the individual ship concerned. Designers should consider future changes in the purpose of the ship, and availability of new equipments, in their bridge designs
