我首先说下事情的始末。有船东中标后,要求船厂现有完工海工船满足沙特阿拉伯的规范要求(有兴趣的船友可以查收附件),其中有一条关于提供VSAT的描述。
5.15 VSAT Communication System: Co***actor shall provide VSAT communications system or equivalent, capable of providing continuous, uninterrupted data and voice communication with speeds capable of sending at a minimum rate of 250 mbps for a single 2MB email. Additional band width is required for additional business computers attached to the system that would normally be operating simultaneously.
因本船已安装有卫星宽带FBB250,其实在功能上说完全可以替代VSAT而且更适用于A3海区,资料显示Max. 284 kbps.
目前的侧重点为VSAT描述中的250 mbps。按照普通居民住房来说,电信100M光纤换算的理论速率为100M的1/8也就是12.5M/S,逆推如要达到250 mbps 即要达到2000M宽带,个人感觉是不符合实际的,这还不谈航行区域和海况的影响。
难道沙特阿拉伯的规范要求中会有如此明显的错误吗?请各位船友发布意见。
