Advantages of Preservation of Obligatory Voice Communication on the VHF Radio Channel 16 [PDF]

TransNav, 2010
Channel 16 of the VHF radio band is the most commonly used way of communication between vessels. Alt-hough there are strict rules not to use it for routine communication, many officers neglect them.

Visual Condition at Sea for the Safety Navigation [PDF]

TransNav, 2011
To the navigation officers of the watch (OOW?s) on the navigation bridge the environmental condition of visual acuity is the most important factor for keeping a proper look-out, as regulated by the IMO COLREG?s (Rule 5).

Probabilistic Intent Inference for Predicting the Compliance with COLREGs between Two Surface Ships

, 2020
The international regulations for preventing collisions at sea (COLREGs) are the rules of the road for marine surface vessels. However, certain ships fail to comply with COLREGs and their non-compliance poses a greater danger to the maritime safety. This

COLREGs Misunderstood or Ignored?

CINEC Academic Journal
As various scholarly articles and accident investigation reports indicate, the risk of collisions at sea is still high. The objective of this research is to identify if this is due to misunderstanding of the International Regulations for Preventing Collisions at Sea 1972, as amended (COLREGs), by watchkeeping officers working onboard cargo ships.
