Lightvessel requires assistance

Have you encountered ice?

Close drift ice
Open drift ice
My starboard warp has parted
My port warp has parted
Onset was sudden
I have cut the warps

It is dangerous to stop
It is dangerous to remain in present position
It is dangerous to proceed on present course
I can only assist if you will make all efforts to follow

The Trawls are engaged
Can you lead me into port?

You should steer in my wake

Ice situation has deteriorated
warning of pressure ridges

Explosion has occurred in tank

Your distress signals are understood

I am on fire in the engine room

You should steer more to starboard

I am steering more to starboard

You should steer towards me

I am steering towards you

You should come as near as possible

I am adrift
Navigation has stopped
My position is doubtful

You are seen – assistance will be given as soon as possible
