海洋石油平台涂装工程涂料损耗分析

Analysis of Paint Loss During Coating Operation in Offshore Platform

涂料的损耗控制一直都是涂装施工的重要环节,由于造成损耗的因素过多,设计方、施工方、涂料制造商都很难精确地计算损耗系数,很不利于施工管理和成本控制。海洋工程是个新兴的产业,施工中涂料的损耗常借鉴造船行业的经验,但由于二者在涂装工艺、结构、涂装设备等方面存在着很大的不同,导致损耗的差别很大。通过对国内石油行业多个海洋石油平台的涂装工程施工,积累了海洋工程涂料的使用数据,对影响涂料损耗的表面粗糙度、涂装方式、钢结构的几何形状、操作技术、环境因素、涂料浪费、修补等各项因素进行分析,尝试对涂料的损耗系数进行精确的统计。通过制定减少损耗的措施,在施工中严格控制,保证了新建海洋石油平台的涂料损耗系数控制在1.0～1.5之间,使涂料损耗达到了比较精准的控制。

The paint loss control always be the key step of coating work, due to various factors of paint loss, it is difficult for the designers, constructors and paint manufacturers to calculate the paint loss percen- tage accurately, against for construction management and cost control. Offshore Engineering is the emerging industry, the paint loss rate in shipbuilding industry is always be adopted for calculation of offshore coating activities, but they are different in coating process, structures and coating equipment, leading to big differ- ence in paint loss between two industries. Based on the accumulating usage data of offshore paint in many domestic of[~hore platforms, the factors affecting the paint loss, such as surf＇ace roughness, coating process, steelwork geometh＇y, operation technology, environmental factors, paint waste and paint maintenance, etc. were analysed to try, to calculate paint loss accurately. By working out measure to decrease wastage and strict control in application, it can be ensured that the paint loss factor for new built offshore platforms will be con- troled within 1.0 to 1.5, and make the paint loss control much accurately.
