Features and General Design Requirements of High-Speed Craft Complying With 2000 HSC CODE
ZHANG Wei, QU Ningning, DUAN Yulong
Ship & Boat    2024, 35 (03): 60-67.   DOI: 10.19423/j.cnki.31-1561/u.2024.03.006

High-speed crafts need to apply regulations that are different from conventional ships due to the characteristics of high speed, light weight and special operations. The International Code of Safety for High-Speed Craft issued at 2000 ( 2000 HSC CODE), as a relatively complete rule applicable to the high-speed craft, is widely accepted by various Maritime Administrations as the design basis for the high-speed craft. The safety principles of the 2000 HSC CODE and the applicability to various Maritime Administrations are briefly introduced. Then the accident types and causes of the high-speed craft are analyzed through domestic and international high-speed craft accidents. And the risk control and design measures applicable to the high-speed craft are further introduced, including general design requirements such as operation restrictions, damage stability, fire protection and evacuation analysis, for understanding the safety principles and guiding the design of the high-speed craft.

Standard Requirements of DNVGL CLEAN(DESIGN)and Application in Machinery Design for Container Vessel
YAO Fei, DONG Yue, LI Hua, DUAN Yulong, MA Tianshuai
Ship & Boat    2023, 34 (02): 88-93.   DOI: 10.19423/j.cnki.31-1561/u.2023.02.088

With the increasingly stringent requirements of marine environmental protection, all major classification societies have proposed their own environmental protection class notations. Among them, the additional class notation of DNVGL CLEAN(DESIGN)additional notation sets requirements for the design, operation and equipment of ships to reduce the ship's environmental impact from air emissions, sea discharges and hazardous materials from ship to shore. The environmental notation CLEAN(DESIGN)is quite stringent in the DNVGL rules, which is rarely used in the design of container vessels in recent years. A dual-fuel container vessel is a green ship that has the notation CLEAN(DESIGN). In the process of research and development, the container vessel has broken through a series of design essentials, such as the arrangement of engine room and liquid tanks, sewage treatment and fuel tank protection, reaching a new level of green environmental protection for container vessels. This article systematically summarizes the requirements of CLEAN(DESIGN)notation for the machinery design of container vessels, and studies the influence of this notation on the machinery design of container vessels. It also shows the design ideas and schemes of this vessel combining with the practical project, and presents measures for further improvement of the environmental protection level of container vessels.
