Description

一种无海水压载的油船 技术领域
本实用新型涉及船舶设计及制造领域， 尤其涉及一种无海水压载的油船。 背景技术
如图 1所示， 目前， 除一些在 20至 30年前早期建造的老龄油船外，传统油船 均具有平直型船底 1、 货油舱双壳结构 2、 货油舱范围设有专用海水压载舱 3、 首 尾区域设有调节海水压载抢等特征。 而传统油船为保证有足够的货油抢容积载 货， 其船身基本上均为肥大的船型， 而且吨位愈大就愈丰满。 当船舶空载航行 时， 为确保尾部螺旋桨全部浸没于水下以及防止波浪对首部船底的拍击， 通常 利用海水压载的方法， 增加船舶重量将船身下沉至一定的吃水， 从而确保船舶 的正常航行。
但是， 建造这个专用的海水压载舱的工艺， 采用的涂漆， 喷砂涂装车间及 配套设备和压载水处理装置系统必须要符合国际海事组织 IM0的 《船舶压载抢保 护涂层性能标准》和《国际船舶压裁水和沉积物控制与管理公约》 的相关规定， 这就大大增加了油船的造船成本和船舶保养及维修的费用， 给造船厂家以及修 船业带来严重的影响。
实用新型内容
为了减少因为建造或维修保养海水压载舱而带来的高额费用， 并且节省能 源， 本实用新型提出新的技术解决方案， 具体内容如下：
一种无海水压载的油船， 包括船体， 货油舱， 所述的货油舱内置于船体中， 所述船体底部呈 V型。 在船舶空载吃水以下及船舶空载排水量不变的条件下， 利 用横截面积等效原理， 在船舶长度范围， 由传统平底转变为新型 V型底， 就可以 达到船舶基线下移一定深度， 即可以使船舶吃水增加相应的值的目的， 并且船 体和货油抢之间的空腔不再装载海水。
这样就可以无须受制于 《船舶压载抢保护涂层性能标准》 和《国际船舶压 裁水和沉积物控制与管理公约》， 也免受为满足上述标准而带来的高额费用。
而且， 所述船体的首尾区域还分别设有调节舱， 所述调节舱为淡水舱或燃 油舱， 其布置原则是符合船舶入级规范对船舶空载时首尾吃水的相关规定。 并 且， 当油船需要淡水洗抢时， 船体和货油抢之间的空腔则可布置洗抢用淡水抢。 满足了使用者对多样化功能的需求。
另外， 所述货油抢底部呈 V型， 这样对货油残余液体的清抢变得非常容易。 本实用新型产生如下有益效果：
本实用新型由于船舶无海水压载舱， 节省了建造或维修保养海水压载舱而 带来的高额费用， 同时可使船舶在排水量不变或基本不变的条件下， 船体在水 下的形状变得瘦小一些， 从而可减少船体阻力， 节省了能源的使用。
附图说明
图 1为传统的平底油船中横剖面图；
图 2为本实用新型 V型底油船中横剖面图。
具体实施方式
如图 2所示， 本实用新型包括包括船体 1 , 货油舱 2 , 货油舱 2内置于船体 1中。 船体 1底部和货油舱 2底部分别呈 V型。 并且， 船体 1的首尾区域还分别设有调节 舱， 这个调节舱可以为淡水抢或燃油舱。
在船舶空载吃水以下及船舶空载排水量不变的条件下， 利用横截面积等效 原理， 在船舶长度范围， 由传统平底转变为新型 V型底， 就可以达到船舶基线下 移一定深度， 即可以使船舶吃水增加相应的值的目的， 并且船体 1和货油舱 2之 间的空腔 4不再装载海水。 这种 V型设计的油船， 无须设置海水压载抢， 就可以 达到设有海水压载舱的油船的相同功能， 并且无须受制于 《船舶压载抢保护涂 层性能标准》和《国际船舶压裁水和沉积物控制与管理公约》， 也免受为满足上 述标准而带来的高额费用， 节省了造船和维修保养成本。
而货油抢 2底部呈 V型， 这样对货油残余液体的清抢变得非常容易。
并且， 在船体 1的首尾区域分别设置的调节舱， 其布置原则是符合船舶入级 规范对船舶空载时首尾吃水的相关规定。 并且， 当油船需要淡水洗抢时， 船体 和货油抢之间的空腔则可布置洗抢用淡水抢。 满足了使用者对多样化功能的需 求。
对于本领域的技术人员来说， 可根据以上描述的技术方案以及构思， 作出 其他各种相应的改变以及变形， 而所有的这些改变以及变形都应该属于本实用 新型权利要求的保护范围之内。
