When taking on ballast waters, the date and time of commencement and completion of the ballast operation, ship’s position, salinity (specific gravity) and amount of ballast water taken onboard must be recorded in the ship’s Deck Log Book. ...
Here are Important things you need to know about ship Ballast and De-ballast operation . In shipbuilding, the word “stability” matters a lot. Therefore, ship was built in such a way that she can Withstand the roughness of the sea with or without cargo. The word Ballast is always use i...
The stiffness is increased by moving the ballast windward to balance a part of the heel and if designed for, the trim angle is also corrected on the same principle. The operation is performed manually or automatically by computerized means like a PLC. In some versions this system is meeting ...
The ship was furnished with ballast. 船上装了压舱物。 So are the motions of a little vessel without ballast tossed about on a stormy sea. 在惊涛骇浪的大海上,一只没有压舱物的小船就是这样颠颠簸簸。 The starting time is the time the ballast needs to light and stabilise the lamp. ...

A common central line (21) runs along the bottom of the ship and at the level of or essentially below the bottom of the ballast tanks (24, 28). At least one valve is located between each tank and the central line. The valve serves to fill or essentially completely empty each tank. ...
At least one trunk extending longitudinally from a first end at a bow of the ship to a second end at a stern of the ship. The first and second ends of the trunk connectible to the water surrounding the ship by operation of an inlet valve and an outlet valve adjacent each end. When ...
Ballast water exchange (BWE) has been the key strategy used to minimize such introductions, but its efficacy is highly variable with studies showing that depending on ship type, method, and location of exchange, and type of organism, BWE purges only 70–100% of planktonic organisms, but is ...
The date 1 to be entered corresponding to the original date of operation and subsequent entry date 2 to be the current date. 该条目后面是与遗漏的操作相关的条目。输入的日期1对应于原操作日期,随后输入的日期2为当前日期。 Example 26:Ship unable to perform ballast water exchange owing to safety re...
The solution exploits available on-board waste energy to treat ballast water making it the most sustainable system in the market. It does not require the use of UV or filters which leads to simple maintainance and operation. It is bothUSCG and IMO Type Approved ...
