Some standard content:
GB/T17383---1998bzxz.net This standard adopts ISO8385:1990 "Shipbuilding and offshore structures-Classification of dredgers". Appendix A of this standard is the appendix of the original ISO standard. This standard is proposed by China State Shipbuilding Corporation. This standard is under the jurisdiction of the Comprehensive Technical and Economic Research Institute of China State Shipbuilding Corporation. The drafting unit of this standard: Comprehensive Technical and Economic Research Institute of China State Shipbuilding Corporation. The main drafter of this standard: Kang Yuan. GB/T17383 ISO Foreword ISO (International Organization for Standardization) is an international organization of national standardization bodies (ISO member groups). The formulation of international standards is carried out by IS) technical committees. Each member group has the right to participate in the committee if it is interested in the subject of a technical committee. Governmental and non-governmental international organizations associated with ISO may also participate in this work. IS and the International Electrotechnical Commission (IE) work closely in all fields of electrical standardization. Draft international standards adopted by the technical committees are sent to the member bodies for approval before they are approved as international standards by the ISO Council. According to the ISO standard-setting procedure, a draft international standard needs at least 75% of the member bodies to vote in favor to become an international standard. International standard ISO8385 was prepared by ISO/TC8-Shipbuilding and offshore structures Technical Committee. Appendix A only provides information related to this standard. 1 Scope National Standard of the People's Republic of China Shipbuilding and offshore structures Dredgers Shipbuilding and marine structures-Dredgers--- Classification GB/T 17383--1998 idt ISO 8385:1990 This standard specifies the classification of various types of dredgers designed to change the size of a waterway by digging or moving mud. Dredgers include ships or floating structures used for dredging purposes. 2 Classification Dredgers are classified according to the provisions of 1 to 11 in Table 1: 1) Operation area; 2) Ten physical characteristics; 3) Power plant: 4) Mobility; 5) Transportability; 6) Crew accommodation: 7) Location of dredging equipment; 8) Operation movement; 9) Shifting and propulsion equipment; 10) Dredging method; 11) Transportation of excavated materials.
