摘要
文章以锦州9-3筒型基础系缆平台为对象,在拖航速度、筒位置以及平台吃水深度一定的条件下,通过模型试验测定了平台在不同规则波浪中拖航时的平台运动加速度、筒内气压力、筒底水压力以及拖缆力,并对试验数据进行比较分析,用于研究波浪对筒型基础平台随浪、顶浪拖航时的影响分析。试验结果表明:筒型基础平台可在渤海水域十年一遇有义波高4.5m的巨浪中拖航,在波高2m以下,航速2节以内,随浪拖航与顶浪拖航均有较高的稳性以及耐波性;顶浪拖航平台的垂荡运动要比随浪拖航时剧烈,随浪拖航平台的稳性以及耐波性要优于顶浪拖航;平台在大浪中拖航时,随浪拖航容许航速要高于顶浪拖航容许航速。
The internal air pressure and bottom water pressure of the bucket, the acceleration and hauling power of platform were determined in the towing of the bucket foundation platform in different regular waves, under conditions of a certain towing velocity, position of buckets and draught of the platform, as Jinzhou 9-3 bucket foundation platform for example. The determinations were performed using model test and the comparison and analysis on test data were performed for the impact analysis of the waves on the towing of bucket foundation platform in following and head waves. The bucket foundation platform can be towed under 4.5m significant wave height in Bohai, which occurs one time every 10 years; if wave heights are limited to 2 m and towing velocities are limited to 2 knots, the towing of the platform in following and head waves both have good stability and seakeeping.Comparing towing of the platform in following and head waves, the heaving of the former is more strenuous than that of the latter; the stability and seakeep- ing of the former is better than those of the latter;the allowable towing velocity of the former is higher than that of the latter.
