ClassNK- Tec 0912
ClassNK issues Technical Information TEC 0912 regarding treatment of ECDIS not displaying radar video.
ECDIS is required to display Radar video, ARPA information and AIS information.
This requirement is applied to main ECDIS for newbuilding ships and does not apply to backup ECDIS or ECDIS installed on board existing ships.
When the newbuilding ships are installed with an ECDIS which is:
1. not provided with a radar video overlay function,
2. not able to connect to other manufacturers radar,
or
3. when the newbuilding ships equipped with radar that does not provide an interface unit for radar video and ARPA function,
ClassNK will accept an ECDIS without any radar overlay under the following conditions:
1. The ECDIS should be located beside the radar display, and
