Electric Load Analysis for Ship

Get an education. Get some experience. Get a life!

You, obviously do not comprehend the task.

Look for my new book,"how to divine electrical subsystem requirements for unbuilt ships". It's free.

good morning, sir

respected gentleman

I am very hapy to see this exclusive noting

I would be very happy and kind enough, If, I receive the " how to divine electrical subsystem requirements for unbuilt ships"

my email arkf442@gmail.com

thankyou very much

Unlike building electrical load analysis (which is easier) this isn't a simple question as a great deal of knowledge in different areas is necessary to perform even a half-decent analysis.

I know of no books that can give you the broad level of knowledge you need (the book "how to divine electrical subsystem requirements for unbuilt ships" is out of circulation as far as I am aware)

...................

A starting point is probably to get an idea by looking at an electrical analysis of a similar ship, reading electrical standards relating to shipbuilding, search of the internet (plenty of information there), talking with your peers, further education.

Can you provide more information? Size of ship? Commercial? Military? Standard electrical loads or sizing the entire ship's electrical system?

Thanks for the tremendous wisdom lynlynch. I bet you knew it all inside out the moment you opened your eyes for the first time.

@jack:Thanks man.. i guess I'll have to be by myself. Will start by fishing the net... you know abt some hepful links?

No specific ones with the broad question you have given.

Can you supply more information? What's the application and your roll in this project/school assignment/hobby?

I am from the builder's side... and it's a patrol vessel.

If you work for the builder, you need to get the design engineer to do his job.

Unless your firm is doing the design as well, you should have been given full plans and specifications for the electrical system to be deployed in this vessel.

If your firm did not do the design, stop now, go no further, and go and get the required plans and specs from whomever did the design. A military system has requirements that are not to be trifled with.

While it is a given that people's lives depend upon the nature of any electrical system, the importance of the electrical system to a military vessel is of much greater importance. Kind of hard to fight when your tools don't work.

If your firm is to do the design, start as in any electrical demand calculation. Identify all of the zones of the boat, and identify the load characteristics of each zone. Identify all of the power loads. Identify redundant systems that may need to be powered simultaneously, the list goes on and on... not an easy task.

Perhaps... if your firm is tasked with the design, your firm might want to consider farming this aspect of the design out to a design house with experience in electrical systems for military vessels and systems.

Dear All,

I am working for the Marine Industry .... Now looking for the Code which can guide me to calculate the OSV (offshore Supply Vessel) or.... other accommodation barge or..... for DC and AC Electrical Analysis please help anyone who have experince

Codarra Advanced Systems has an Electrical Loads Analysis software application which will help you if you have a design or even a slight idea of what your ship has to manage.

Mr......

Load analysis for ship is depending of the ship you are going to design and classification society. since you need to get approval from the Society for the same. But in general, Column-1 List out all the systems, inductive loads and other loads

Column-2 Rating/Load of Each system in KW

Column-3 Multiply with Quantity ie., Connected load

Column-4,5,6,etc Classify the application with Utility factor in % for each system(Eg- Sailing Load, Harbour Load, & towing load etc.,

Futher to the above, total the inductive load in Kw under sailing,Harbour,towing etc

Then Multiply with Diversity factor with total inductive load of each application.

Now total the other load such as a/c,vent fans

Add all the load as in KW and convert in KVA

So, Now you can select your DG by refereing rule book (Normally it should be 1.2 time of nominal load.
