主要从造船业的角度，聚焦在“船舶”和“海洋工程”油气钻采装置。描述了“海洋钢结构物”的特点、设计准则与钢材选用原则，并列出了典型运输船舶与海洋油气工程装置载体的钢材用量，以及海洋油气工程装置中典型钢管材料用量。讲述了造船业中常用的低碳钢、高强度钢、超高强度钢、特殊钢与铸钢5大类材料的共性要求，并列举了载体特殊要求的超高强度钢与特殊钢（主要是低温钢、耐腐蚀钢、抗层状撕裂钢、抗焊接裂纹钢、铸钢和低磁钢）。介绍了海洋钢结构物中钢管的应用。同时建议对我国造船用钢市场，应“理顺体系、沟通需求、重点突破、贴近工程”。

Just like the structure in the aerospace which is defined as aircraft internationally , is divided into aviation and astronavigation, the author divides the structure in the sea which is collectively named as marine steel structure into two branches, i.e.ship and marine engineering .The author focuses on marine and offshore oil and gas drilling equipment mainly from the perspective of the shipbuilding industry , describes the features, design criteria and steel selection princi-ples of marine steel structures, and lists the steel amount of typical transport ships and the carriers of offshore oil and gas engineering plants, as well as the mount of the typical steel pipes on the offshore oil and gas engineering plants .The au-thor tells about the special requirements for Extra High Strength Steel and Special Steel (including Low Temperature Steel, Corrosion-Resistant Steel, Lamellar-Tearing-Resistance Steel, Welding-Crack-Resistance Steel, Cast and Low Magnetic Steel mainly) on carriers.The author also introduces the applications of steel pipe on marine steel structures .For becom-ing the powerful country on shipbuilding and marine industry , Chinese metallurgical industry is to contribute .The author also suggests that Chinese shipbuilding steel market should rationalize the system and communication needs , stand out es-sentials and get close to projects.
