24 1.3 Console configuration Consoles shall principally be divided into two areas: a vertical (slanting) part for location of information displays to be easily readable (see Figure 1) a horizontal part (desktop) for controls, switches and buttons to be within easy reach from the working position. Part 6 Chapter 3 Section 3 Figure 1 Easily readable 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.)

25 Figure 2 The console in front of a seated working position shall provide sufficient leg room 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. Part 6 Chapter 3 Section 3 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 Figure 3 for eye heights at standing position Figure 3 Console height Rules for classification: High speed and light craft DNVGL-RU-HSLC-Pt6Ch3. Edition December 2015 Page 25

26 1.3.4 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, are installed on top of the console, the total height should not exceed the prescribed 1300 mm. 1.4 Windows 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 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. Part 6 Chapter 3 Section 3 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 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 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 ) 1.5 Chairs 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. Rules for classification: High speed and light craft DNVGL-RU-HSLC-Pt6Ch3. Edition December 2015 Page 26

27 1.5.2 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. 1.6 Operating compartment 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. (HSC Code ) 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 ) Part 6 Chapter 3 Section 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 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 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 Figure 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.

28 Part 6 Chapter 3 Section 3 Figure 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 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 Figure 5, within reach from the working position at both workstations.
