Although the STCW Convention is the most significant development in the
area of seafarers training, certification and watchkeeping, in IMO's own admission, the
Convention was increasingly becoming outdated. The organisation therefore undertook a
major review of the Convention in 1993 culminating with the adoption by an international
conference of the 1995 Revision. Skill and competence requirements are now specified in
the form of tables given in a Code. The tables in the Code specify the competence
requirements and give the knowledge, understanding and proficiency needed to fulfill each
competence. The table also list methods for demonstrating competence which include use of
simulators and practical demonstration of skills. The criteria for evaluating competence
is also given by determination of accepted parameters of assessment results. It is in
these tables that the use of radar and ARPA simulators become mandatory. The provisions
also take into account new technology by accepting ECDIS systems in the term
