These new rules encompasses both the Deck and Engine Departments and are applicable to those candidates commencing their initial training on or after the date of coming into force of these rules.

The Merchant Shipping Notice containing the detailed guidelines for examination system for Marine Engineer Officers to usher in the new Rules and to upgrade the existing certificates are drawn up and enclosed for your information and necessary action.

You are hereby advised to kindly ensure that this Merchant Shipping Notice is available to all concerned.

Yours faithfuly,sd/(A Chatterjee)Dy. Chief Surveyor with the Govt.Of India.

PreambleMerchant Shipping Notice No:11/98EXAMINATION SYSTEM FOR MARINE ENGINEER OFFICERS

The new examination rules for engineers will come into force from 1st August 1998 and will supersede the existing rules called the Merchant Shipping (Examination of Engineer Officers in the Merchant Navy) Rules, 1989, and as amended in 1994, referred to as the old rules. 

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 as amended on the 7th day of July, 1995 and has entered into force on the 1st 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 under the old rules will expire on 31st January 2002. Holders of each such Certificate of Competency will be required to upgrade their Certificates by undergoing an upgradation course and subsequent examination for validity beyond this date.
