As a consequence, the horizontal field of vision from the command and navigation workstations shall at least extend over an arc from 22.5 abaft the beam on one side, through dead ahead, to 22.5 abaft the beam on the other side. 202 The total arc of blind sectors from right ahead to 22.5 abaft the beam on either side shall not exceed 20. Each individual blind sector shall not exceed 5. The clear sector between two blind sectors shall not be less than 10. (HSC Code ) 203 The field of vision while seated at the workstation for command and the workstation for navigation shall allow a forward view of the bow. Furthermore, the view of the sea surface from the workstations for command and navigation shall not be obscured by more than one (1) craft length in any direction from dead ahead to at least 90 on each respective side. The sea surface view from the workstations shall not be obscured with more than one (1) craft length from dead ahead to at least 90º to the side where the workstation is located 204 The field of vision from the workstation for command and the workstation for navigation shall enable the navigator to utilise leading marks astern of the craft as means for track monitoring. A horizontal field of vision of at least 10 degrees should be obtained dead astern from each workstation. 205 The field of vision from the workstations for command and navigation shall permit the navigator to position the craft alongside a wharf without difficulty, to both port and starboard side respectively. Alternatively; separate docking workstation(s) shall be located in adequate position(s). While seated at the starboard workstation; the operator should be able to see the distance from the ship's starboard side to the wharf both fore and aft. While seated at the port workstation; the operator should be able to see the distance from the ship's port side to the wharf both fore and aft. For craft which cannot achieve the required field of vision without unreasonable difficulty a number of video cameras in suitable positions may be an acceptable solution which is subject to approval in each case. A 300 Console configuration 301 Consoles shall principally be divided into two areas: a vertical (slanting) part for location of information displays to be easily readable (see Fig.1) a horizontal part (desktop) for controls, switches and buttons to be within easy reach from the working position. Fig. 1 Easily readable

13 Pt.6 Ch.8 Sec.3 Page The height of console desktops at the workplaces for navigation, manoeuvring, traffic surveillance and monitoring shall enable easy use of equipment required for safe performance of the tasks to be performed from both standing, when applicable, and sitting position. - To provide a functional reach from sitting position, the sitting height is governed by the elbow height in relation to console desktop. - To provide a functional reach of equipment and easy operation of controls from sitting position, the elbow height of the operator should preferably be 50 mm higher than the console desktop and not less than the height of the desktop. - To provide the elbow height required for persons of different size and build in relation to the console desktop, it should be possible to adjust the height of the seat to allow an elbow height of 240 mm +/- 55 mm above the seat. It should be possible to adjust chair armrests accordingly, if installed, and to fold the armrests away. The leg room should have a depth of 450 mm and not less than required for a person sitting at a working position 350 mm from the console (chair backrest 440 mm from the edge of the console, requiring a leg room depth of at least 230 mm.) 800 Fold-away arm rest 240 +/- 55 Adjustable Desktop + 50 mm Fig. 2 The console in front of a seated working position shall provide sufficient leg room. 303 The top of the consoles forming the front workstations shall not be higher than 1200 mm, including the foundation of the consoles. The top of the consoles shall not obstruct the field of vision over the lower edge of the windows in front of the workstation from sitting position. The console height should not exceed 1200 mm. This console height may be accepted for installation at a distance of 350 mm or more from the window, also if it interferes with the line of sight from an eye height of 1400 mm, providing the height of the chair can be adjusted to compensate for the interference. See Fig.3 for eye heights at standing position Standing Sitting 790 +/ / mm chair adjustment Fig. 3 Console height

14 Pt.6 Ch.8 Sec.3 Page Consoles within the required field of vision aft of the front workstation consoles shall not obstruct the horizontal line of sight from the sitting eye height. The height of the consoles should be 100 mm lower than the horizontal line of sight from a seated position and should not exceed 1300 mm. If printers, or other equipment, is installed on top of the console, the total height should not exceed the prescribed 1300 mm. A 400 Windows 401 Divisions between windows, located in the front, on the sides and in the doors, shall be kept to a minimum. No divisions shall be installed immediately forward of the operating stations. (HSC Code ) The framing between windows, especially within the field of vision as described in 200, should not exceed 150 mm. If stiffeners are used, this space should be less than 100 mm and the depth of the stiffeners less than 120 mm. 402 The Society shall be satisfied that a clear view through the operating compartment windows is provided at all times regardless of weather conditions. The means provided for maintaining the windows in a clear condition shall be so arranged that no reasonably probable single failure can result in a reduction of the cleared field of vision such as to interfere seriously with the ability of the operating crew to continue the operation and bring the craft to rest. Efficient systems should be provided, including heavy duty wipers, fresh-water wash, de-misting and de-icing. Operating controls to be positioned within reach while seated at the workstation for the officer in charge or assisting officer. 403 Arrangements shall be provided so that the forward view from operating stations is not adversely affected by solar glare. Neither polarised nor tinted window glass shall be fitted. (HSC Code ) Removable sunscreens or sun curtains with minimum colour distortion should be provided for at least the front windows. 404 Operating compartment windows shall be angled to reduce unwanted reflection. (HSC Code ) The windows in front should preferably be angled top outwards, 15 to 25 from the vertical, see also ISO The windows shall be made of material which will not break into dangerous fragments if fractured. (HSC Code ) A 500 Chairs 501 When a chair at a station from which the craft may be operated has been adjusted so as to suit the occupant, subsequent change of seat position to operate any control shall not be acceptable. 502 Installed chair at a workplace for operations shall be fastened to rails allowing fore and aft movement of the chair to enable easy reach of equipment when seated and, if applicable, sufficient room to stand in front of the console when the chair is pushed back. It shall be possible to adjust the height of the seat to suit users of different heights for optimum view and reaching distance and armrests, if provided, shall be of fold away type and preferably adjustable in height. The seat height of the chair should be adjustable from 550 to 670 mm above the deck surface. The movement in fore-aft direction should allow the front edge of the seat to be positioned at the edge of the front console and to allow a free space of at least 700 mm between the chair and console when moved in aft direction. Armrests should preferably be adjustable from 185 and 295 mm above the seat if installed. A 600 Operating compartment 601 The design and arrangement of the operating compartment, including location and layout of the individual workstations, shall ensure the required field of vision for each function. Blind sectors shall be as few and as small as possible, and not adversely affect the keeping of a safe lookout from the operating station. If stiffeners between windows are to be covered, this shall not cause further obstruction inside the wheelhouse. (HSC Code ) (HSC Code ) 602 The craft s operating compartment shall not be used for purposes other than navigation, communications and other functions essential to the safe operation of the craft, its engines, passengers and cargo. 603 The operating compartment shall be provided with an integrated operating station for command, navigation, manoeuvring and communication and so arranged that it can accommodate those persons required to navigate the craft safely. 604 The arrangement of equipment and means for navigation, manoeuvring, control, communication and other essential instruments shall be located sufficiently close together to enable both the officer in charge and any assisting officer to receive all necessary information and to use the equipment and controls, as required, while they are seated. If necessary, the equipment and means serving these functions shall be duplicated. A functional workstation designed in accordance with the established overall operational and ergonomic requirements must provide: a sufficient area for performance of the tasks to be carried out by the number of people that may be required to attend consoles designed for operations at specific workplaces in standing and seated position, enabling installation of equipment to be within reach (see Fig.5) from the working position avoiding obstruction of the view through bridge windows from seated position chairs suiting ergonomic requirements for efficient use of installed equipment and maintenance of field of vision, if chairs shall be installed.

15 Pt.6 Ch.8 Sec.3 Page 15 Fig. 4 Within reach Within reach from a seated position is defined as within 1000 mm and within 800 mm for frequently used equipment. Within reach from a standing position is defined as within 800 mm in the forward direction and within 1400 mm in sideways directions. 605 Both workstations is intended to serve both navigation and traffic surveillance and manoeuvring functions, and essential equipment for traffic surveillance and manoeuvring, such as the ARPA and ECDIS. In addition means for controlling speed and course, should be within reach from both workstations. An acceptable solution, instead of the duplication of required equipment, may be to install the essential equipment, indicated in Fig.5, within reach from the working position at both workstations.

16 Pt.6 Ch.8 Sec.3 Page 16 Fig. 5 Example of location of main equipment 606 The command workstation shall enable the following functions or tasks to be performed: surveillance of craft's position, course and speed made good in relation to planned track and surrounding waters by means of ECDIS analyse the traffic situation and decide on collision avoidance manoeuvre alter course change speed effect internal and external communications operate auxiliary manoeuvring systems, if fitted monitor time, course, speed, engine revolutions, pitch or thrust indicator and rudder angle or direction of steering thrust. 607 The navigation workstation shall enable the following functions or tasks to be performed: surveillance of craft's position, course and speed made good in relation to planned track and surrounding waters by means of ECDIS analyse the traffic situation and decide on collision avoidance manoeuvre plotting of the craft's position, course and speed made good alter course change speed effect internal and external communication monitor time, course, speed, engine revolutions, pitch or thrust indicator and rudder angle or direction of steering thrust. In accordance with the functions or tasks to be performed at each workstation, equipment or displays serving the various functions should be available as follows: Workstation for navigation - radar display with chart overlay - ECDIS - engine controls - steering control. Workstation for command - radar display with chart overlay and AIS presentation - radar plotting aid - ECDIS - engine control - steering control. Instruments and equipment of common interest to both the navigation and the command workstation should be located accordingly. Such instruments and equipment, if fitted, include: - automatic steering device - rudder angle or steering thrust indicator - gyro repeater - speed and distance log - engine revolution indicator - pitch or thrust indicator - wind direction and speed indicator - echo sounder - internal communication systems - VHF radiotelephone - emergency stop controls - rate of turn indicator - whistle control - searchlight controls - magnetic compass display - window wiper and wash control - AIS operation unit - clock. If a separate workstation for supervision of engine performance is placed in the operating compartment, the location and use of this workstation shall not interfere with the primary

17 Pt.6 Ch.8 Sec.3 Page 17 functions to be performed in the operating station. (HSC Code ) 608 In all craft, the station or stations in the operating compartment from which control of craft manoeuvring and/or of its main machinery is exercised shall be provided, within easy reach of the crew member at that station, with controls for use in an emergency to: activate fixed fire-extinguishing systems close ventilation openings and stop ventilating machinery supplying spaces covered by fixed fire-extinguishing systems, if not incorporated in preceeding item shut off fuel supplies to machinery in main and auxiliary machinery spaces disconnect all electrical power sources from the normal power distribution system (the operating control shall be guarded to reduce the risk of inadvertent or careless operation), and stop main engine(s) and auxiliary machinery. (HSC Code ) 609 The control panel shall be located in the operating compartment or in the main fire control station. (HSC Code ) Reference to ventilation system control is given in Ch.10 Sec.4 A. 610 The design and layout of the compartment from which the crew operate the craft and the relative positions of the primary controls shall be assessed against the essential operational manning level. Where minimum manning levels are proposed, the design and layout of the primary and communication controls shall form an integrated operational and emergency control centre from which the craft can be controlled under all operational and emergency events by the operating crew without the necessity for any crew member to vacate the compartment. (HSC Code ) 611 The relative positions of the primary controls and the seats shall be such that each operating crew member, with the seat suitably adjusted, and without prejudicing compliance with 15.2 (101) can: without interference, produce full and unrestricted movement of each control both separately and with all practical combinations of movement of other controls, and at all work stations, exert adequate control forces for the operation to be performed. (HSC Code ) 612 In craft where the Society considers the provision of a safety belt necessary for use by the operating crew, it shall be possible for those operating crew members, with their safety belts correctly worn, to comply with 500 except in respect of controls which it can be shown will only be required on very rare occasions and which are not associated with the need for safety restraint. 613 Adequate arrangements shall be made to prevent passengers from distracting the attention of the operating crew. (HSC Code ) A 700 Instrument installation 701 Instruments, instrument panels and controls shall be permanently mounted in consoles or other appropriate places, taking into account operation, maintenance and environmental conditions. However, this shall not prevent the use of new control or display techniques, provided the facilities offered are not inferior to recognised standards. (HSC Code ) 702 All instruments shall be logically grouped according to their functions. In order to reduce to a minimum the risk of confusion, instruments shall not be rationalised by sharing functions or by interswitching. (HSC Code ) 703 Instruments required for use by any member of the operating crew shall be plainly visible and easily read: with minimum practicable deviation from his normal seating position and line of vision, and with the minimum risk of confusion under all likely operating conditions. (HSC Code ) 704 Instruments essential for the safe operation of the craft shall be clearly marked with any limitation if this information is not otherwise clearly presented to the operating crew. The instrument panels forming the emergency control for the launching of life rafts and the monitoring of the fire-fighting systems shall be in separate and clearly defined positions within the operating area. (HSC Code ) 705 The instruments and controls shall be provided with means for screening and dimming in order to minimise glare and reflections and prevent them being obscured by strong light. (HSC Code ) 706 The surfaces of console tops and instruments shall have dark glare-free colours. (HSC Code ) 707 Instruments and displays, providing visual information to more than one person, shall be located for easy viewing by all users concurrently. If this is not possible, the instrument or display shall be duplicated. (HSC Code ) 708 If no ENC is available in the operation area, the operating compartment shall be provided with means for chart work. There shall be facilities for lighting the chart. Chart table lighting shall be screened. A 800 Communication facilities 801 Such means as are necessary shall be provided to enable the crew to communicate between, and have access to, each other and with other occupants of the craft in both normal and emergency conditions. (HSC Code ) 802 Means to communicate between the operating compartment and spaces containing essential machinery, including any emergency steering position, irrespective of whether the machinery is remotely or locally controlled, shall be provided. (HSC Code ) 803 Where control of propulsion and manoeuvring is provided at stations outside the operating compartment, such stations shall have direct communication with the operating compartment which shall be a continuously manned control station. (HSC Code ) 804 Where control of propulsion or manoeuvring is provided at stations adjacent to but outside the operating compartment, the transfer of control shall only be effected from the station which takes charge of control. Two-way voice communication shall be provided between all stations from which control functions may be exercised and between each such station and the look-out position. (HSC Code ) 805 Adequate arrangements shall be provided for two-way
