How to include conditions of class in the graphical survey schedule

General Usage

  • The class status for surveys etc on a selected vessel is highlighted by means of coloured indicator lamps with meanings as shown:


(Red) Overdue


(Yellow) Due /warning (within  time window or within 3 months of due date)

Not due

(Green) Not due

Not Applicable

(Grey) Not Applicable
  • Headings etc shown underlined generally provide the link by clicking on their name to that particular feature. For example in the class Status screen, Certificates, Surveys, CC/MO and CMS are shown on 'tabs' Once a tab is selected it loses its underline. So in the example to the right, Surveys are selected, and Conditions of class and  Memos are available by clicking on CC/MO

  • Where the screen has an empty region at the bottom, it is generally there to display information from a selection elsewhere in the screen. For example in the Survey Schedule, if you click on a survey name, the details of that surveys due dates, time window etc will be displayed, without having to leave the survey schedule.
