超大型风电安装船抗横倾系统的设计原理及应用

Design Principle and Application of Anti-heeling System for Ultra Large WindTurbine Installation Vessel

目前海上风机、升压站等相关主配套单元的安装主要采用自升式安装船或者浮式重吊船,当该类船舶在浮态进行吊装的时候,由于所吊物件的质量较大,进行吊装作业时,在保证船舶安全的前提下如何提高装机速率显得尤为重要,则此时具有良好的抗衡倾系统的船舶来执行此类工作是满足以上要求的必不可少的保证。抗衡倾系统主要是通过控制船舶左右两舷的压载舱的压载水,在船舶进行吊重过程中使船舶时刻保持在平衡的状态,从而保证船舶的安全性。抗衡倾系统的设计分为主动补偿和被动补偿两种方式,其中主动补偿在现有船舶中应用较少,以某5000 t风电安装船为例,阐述了两种补偿方式的应用。

At present,the installation of offshore wind turbines,booster stations and other related main supporting units mainly adopts self elevating installation vessels or floating heavy lifting vessels.When such vessels are hoisted in the floating state,due to the large mass of the lifted objects,it is particularly important to improve the installation rate on the premise of ensuring the safety of the ship.At this time,it is an indispensable guarantee to meet the above requirements that ships with good anti-heeling system perform such work.The anti-heeling system is mainly used to control the ballast water in the ballast tanks on the left and right sides of the ship to keep the ship in a balanced state at all times during the lifting process of the ship,so as to ensure the safety of the ship.The anti-heeling system is designed in two ways:active compensation and passive compensation.Active compensation is rarely used in existing ships.Taking a 5000 t wind power installation ship as an example,the application of two compensation methods was described.
