For example, in the case of Japanese flag oil tanker having automatic and remote control systems engaged in international voyage, the Tables 1 to 5, 8, 10, 11 and 12 are applicable.. These tables contain only survey items related to internal examination, opening-up examination, test, measurement and/or confirmation examination except for general condition examination or visual examination. The surveyor may request any examination in addition to those specified in the tables where he deems it necessary. Surveyor may modify the extent and/or requirement of survey, taking into consideration the condition of the relevant part upon reviewing the service record or maintenance record. With regard to thickness measurement of structural members, please refer to Part B of NK Rules. The thickness measurements are necessary for the attendance of the surveyors and thickness measurements of structures in areas where close-up surveys are required are to be carried out simultaneously with close-up surveys. Also, longitudinal strength of hull girder is re-assessed on the basis of the thickness measurements and structural reinforcements may be required if necessary.. 6. ENHANCED SURVEY PROGRAMME (1) IACS unified requirements for enhanced survey programme have been in force since 1 July 1993 for oil tankers and bulk carriers (including ore carriers) and since 1 July 1997 for chemical tankers. At the periodical survey, internal examinations, close-up surveys, thickness measurements and etc. are additionally required. For these survey items, as the means of access for the structural members are specified in our GUIDANCE FOR THE SURVEY AND CONSTRUCTION OF STEEL SHIPS, survey preparation is to follow the Table 13. (2) With effect from 1 July 2001, on ships of the above (1) of 20,000 DWT and above, starting with special survey No. 3, all special and intermediate surveys are to be carried out by at least two exclusive surveyors. Also, with effect from 1 September 2004, on bulk carriers of 100,000 DWT and above of single side skin construction, intermediate survey between 10 and 15 years of age is to be performed by at least two exclusive surveyors. (3) For special surveys for bulk carriers, oil tankers, ships carrying dangerous chemicals in bulk and intermediate survey for bulk carriers, oil tankers, ships carrying dangerous chemicals in bulk over 10 years of age, a specific survey programme identifying the outline of the surveys such as internal examinations, close-up surveys and thickness measurements etc. to be prepared and submitted by the owners to the surveyor’s office in advance. Further, for the bulk carriers and oil tankers of the above, a survey planning questionnaire which would be a part of survey programme is also required to submit prior to preparation of survey programme.
