The caller claimed to have received Ocean Viking telephone number from RCC Malta, which instructed them to contact Ocean Viking, as this vessel is the area. 

The caller informed that the distress boat is without water and they are asking to be rescued. 

The information above seems to indicate the subject boat may be the one referred to by Alarm Phone alert AP1018 and aircraft Seabird2 spotting. 

While informing that Ocean Viking is currently underway to Civitavecchia port as per ITMRCC instructions, Ocean Viking seeks information and instruction in regards to the subject boat.
