船舶旋回操作方式图解

“在苍茫的大海上，狂风卷积着乌云，在乌云和大海之间，海燕像黑色的闪电，高傲地飞翔。”咳咳咳，回到正题。船舶也有类似海燕的属性，在四大洋里航行着，那这么大的钢铁之躯是怎么像海燕一样灵巧地实现转弯换向呢，那本篇文章小编来带大家侃一侃船舶常见的三种旋回方式。

WILLIAMSON TURN

威廉逊回旋法

  • Makes good original track line

  • Good in reduced visibility

  • Simple

  • Slow procedure

  • Takes the ship farther away from the scene

Williamson turn

Rudder hard over  (in an “immediate action”situation,only to the side of the casualty). After deviation from the Original course by 600,Rudder  hard over to the Opposite side.  When heading 200 short  Of opposite

course,rudder  to midship position and ship to be turned to opposite course.

ONE TURN/ANDERSON TURN

单回旋法/安德森回旋法

  • Fastest recovery method

  • Good for ships with tight turning characteristics

  • Used most by ships with tight turning characteristics

  • Very difficult for a single – screw vessel

  • Difficult because approach to person is not straight

Single turn ( 2700  manoeuvre )

Rudder hard over  (in an “immediate action”situation,only to the side of the casualty).After deviation from the original course by 2500

rudder to midship position and stopping manoeuvre to be initiated.

SCHARNOV TURN

斯契诺回旋法

  • Will take vessel back into her wake

  • Less distance is covered, saving time

  • Cannot be carried out effectively unless the time

elapsed between occurrence of  the incident and

the commencement of the manoeuvre is known.

Scharnov turn

(Not to be used in an“immediate action”situation.)Rudder hard over. After deviation from the Original course by 2400 Rudder hard over to the Opposite side. When heading 200 short Of opposite course, rudder  to midship position so that Ship will turn to opposite course.
