Key Points to Understand How Marine Growth Prevention Systems Can Protect Your Ship

 

While ships are in the process of sailing, the fact is that they resort to using seawater for many different needs. The system of the ship uses the water which will be released back into the ocean after use.

While using seawater is efficient and convenient for multiple purposes, it cannot be ignored that the water does possess various marine organisms which make entry into the ship as well. They can be deposited on various parts of the system of the ship and can actually thrive quite well.

But if precautions are not implemented, this marine growth can indeed inflict unwanted damage to various parts of the system of the ship. Here we present the causes and effects of marine growth, along with ways to deal with it effectively.

 

 

 

 

 

 

Seawater is known to possess both micro marine organisms and macro marine organisms

♦ Causes Of Marine Growth

 

Seawater is known to possess both micro marine organisms and macro marine organisms. They can include mollusks, hard shells, barnacles, sea worms, and algae. These organisms have proven time and time again in being notoriously able to stick to various surfaces on the ship. And when they thrive there, the result is what is called marine growth.

There can be large clusters of marine growth which formulate inside the pipelines of the ship. This is primarily due to the result of seawater entering into the system of the ship that processes the seawater.

The organisms locate the ideal spot within the system where the conditions of the environment there appear just right, along with several other pertinent factors that contribute to their prosperity, such as ph balance, temperature, viable nutrients and more. Then they can reproduce and spread vastly with wild, fast growth.

 

 

 

 

 

 

While the marine organisms thrive excessively

♦ Effects Resulting From Marine Growth

 

While the marine organisms thrive excessively, they create blockages or narrowing for the passage of cooling water within the system of the ship, which thus results in several unwanted conditions, such as:

  1. The heat transfer system becomes impaired.
  2. Water-cooled machinery often overheats.
  3. The rate of the corrosion of pipes increases dramatically, along with the presence of thinning pipes.
  4. The vessel can experience a reduction in its efficiency, which results in a loss of time and a loss of speed.

 

 

 

 

 

 

To prevent the formulation of marine growth from overtaking the system of the ship

♦ Dealing With Marine Growth Effectively

 

To prevent the formulation of marine growth from overtaking the system of the ship and causing substantial damage, marine growth prevention methods are necessary.

The primary thesis is that electrolysis is the core of MGPS, the shortened form for the term of marine growth prevention system. This implements the usage of an aluminium sacrificial anode. Copper or ferrous ones may be used as well. Typically, the anodes are paired in the area of the primary sea chest aboard the ship or where they will be in direct contact with the flow of the seawater.

 

 

The system consists of a control unit whose purpose is to supply an impressed current via the anodes. It also monitors these currents. During this process, the anodes create the production of ions, which are transported by the water to the pipes and machinery. The result is these anti-corrosive properties protect the pipes and machinery. Note also that the current is strong enough to prevent marine organisms from settling.

It is great to know that there is a way to keep marine organisms from damaging your ships. It is advised to check your marine growth prevention systems regularly to make sure they are functioning optimally at all times.
