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

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.
