平陆运河航区正式公布

Translate

  9月15日,平陆运河航区正式公布:运河内河段自起点至河海分界,即南宁横州市平塘江口至G75兰海高速钦江大桥,暂定为“内河B级航区”。这标志着新中国成立以来第一条通江达海运河的航区体系全面确立。

  内河船舶航行区域根据水文、气象条件划分为A、B、C三个等级,字母越靠前,风浪越大,对船舶的安全技术要求越高。根据《航区划分规则》,A级航区5%保证率对应的有义波高不超过2.0米,对船舶的结构强度、稳性、干舷和安全设备要求最高;B级航区5%保证率对应的有义波高不超过1.25米,要求适中;C级航区5%保证率对应的有义波高不超过0.5米,要求相对最低。

  平陆运河的航区体系呈现出清晰的梯度衔接格局。上游郁江段是B级航区,平陆运河内河段同样划为B级航区,两者无缝对接;下游钦州湾河海交界区则已被划定为全国首个“相当A级”航区,意味着该水域风浪条件与内河A级航区“相当”。符合内河A级船舶经检验签注并配备装载手册后,可合法行驶到钦州港完成装卸货。
