These new rules are called the Merchant Shipping (Standards of Training Certification and Watchkeeping for Seafarers) Rules, 1998. The objective of these rules is to give full effect to the provisions of International Convention on Training, Certification and Watchkeeping for Seafarers, 1978 th st as amended on the 7 day of July, 1995 and has entered into f orce on the 1 day of February, 1997. The new rules are applicable to those commencing their initial marine engineering training on or after the date of these rules coming into force. All such initial training programmes and subsequent qualifying sea service at all levels will be well structured and required to be assessed and suitably endorsed by qualified trainers and assessors in the approved Training and Assessment Record Books issued to the candidates. The Chief Engineer Officers and the Second Engineer Officers are required to be such qualified training and assessment officers for the part of training imparted on board including the qualifying sea service. Although the grades of certificates will remain the same as in the old rules, the syllabuses and the subjects for examinations in the new rules have changed to accommodate "function wise" approach. Validity of the M.E.O. Class IV, M.E.O. Class II and M.E.O. Class I Certificates of Competency issued st under the old rules will expire on 31 January 2002.
