In order to be able to control a machine of any sort, the operator needs some form of ‘measuring device’ (sense organs) to receive information from the information displays. For humans, these measuring devices perceive signals giving the information necessary to operate and control the process. Table 10.1 and Table 10.2 summarise the capacity and […]

Survivability
Personnel survivability refers to using system design features that improve safety and operational success while in hostile natural or man-made environments. This includes the progression from the integrity of crew and passenger compartments, through safety, survival, escape and rescue systems, equipment, and procedures (ATOMOS, 1998). 9.8.1 Joint Communication To sum up this chapter, we point […]
SYSTEM SAFETY
A key issue for system safety is to identify and understand the factors that affect human performance in relation to the technical systems being operated and the environment in which work is taking place. This task should start from the early stage of the SCC definition and should refine its results as the design progresses, […]
HEALTH HAZARDS
As an orientation, a list of health hazards is included from the ATOMOS project. These are also factors to consider when designing a ship control centre. Any design project must deal with identification, assessment, and amelioration of short – or longterm hazards to health occurring as a result of normal operation of the SCC. The […]
9.6.2 Visual Alarms
• Visual alarms should clearly differ from routine information on displays. • Visual alarms should be flashing. The flashing display should change to steady display upon acknowledgement. • Acknowledged alarms should be presented by steady display. • Alarm indicators should be designed to show no light in normal conditions (no alarm) or should be nonexistent […]
Alarm Management and Design
• A method of acknowledging all alarms (i. e., to silence audible alarms and to set visual alarms to steady state), including the indication of the source of the alarm, should be provided at the navigating and manoeuvring workstation, to avoid distraction by alarms that require attention but have no direct influence on the safe […]
ALARMS
Alarms and alarm management are a growing problem, both on the bridge and in the ECR. Many alarms are necessary on the bridge, to indicate the status of safety-critical equipment or to alert the operator regarding a dangerous situation. However, the number of alarms and indications has increased from solely being related to navigation to […]
Small Engine Control Rooms
The greatest challenge is, of course, the design of small ECRs. The smaller the available space, the more thought must be spent in the design. If not, the work in the ECR risks becoming restrained through overcrowding (if more than one crew member is present) or inefficient (if a solitary crew member cannot reach all […]
Workstation for Emergency Operations
This is the workstation from which emergency running of the equipment can be performed. 9.5.1.2 Workstation for planning and Documentation This is the workstation at which the operation and maintenance of the engine room and engine control room are planned. 9.5.1.3 Workstation for Administrative duties This is the workstation at which members of the crew […]
