LNG码头系缆墩平面布置

General layout of mooring dolphin in LNG terminal

球罐型LNG船在全球LNG船舶中占比达到22%。其中,5个球罐的LNG船因其管汇位置与OCIMF规定存在很大差异,导致船舶不得不偏心靠泊,因此在对称码头布置情况下的系缆效果较差。通过实例分析对比,研究代表船型在对称和不对称码头布置情况下的系缆情况,得出非对称的平面布置能更好地适应球罐型LNG船的系缆;非对称布置码头在兼顾非球罐型LNG船系缆的前提下,提高了球罐型LNG船的系缆效果,提升了整个码头的靠泊兼容性。

The Moss-type LNG ship accounts for 22%in global LNG carriers.Among them,the manifold of LNG ship with five spherical tanks has a very different position from the OCIMF criteria,resulting in the off-centered berth,and the mooring effect is poor in the case of symmetrical dock arrangement.Through the comparison of examples,the mooring conditions of the representative ship type under the condition of symmetrical and asymmetrical general layout are studied.It is concluded that the asymmetric general layout can better adapt to the mooring of Moss-type LNG ship.Under the premise of taking into account the mooring of non-Moss-type LNG ship,the asymmetric arrangement of wharf improves the mooring effect of Moss-type LNG ship and the berthing compatibility of the whole terminal.
