Cruise Ship Power
Cruise Ship Power
(OP)
I just had a few questions about cruise ship power.
How do they monitor the power while out on a cruise? Is there a substation on the ship? Is there a substation when the ships use shore power? Are there companies that setup shore power for Cruise lines?

For a ship as large as a cruise ship, there will be special shore power specifications and the port and/or the cruise line will be responsible for the power distribution system from the utility interface to the ship.
Utilities don't have a problem for most part. They have rate schedules that take into account the part-time nature of these services. As long as someone is paying the bill, they are happy.

It says, "the new shore power installation is the first of its kind in Canada and only third in the world. It is the result of a $9-million cooperative investment...". Sounds like a full fledged shore power system for a cruise ship may not be that common.

Shipboard systems are different from land based, they are very versitile and flexible on ways to dist power.

The KW part is usually easy as it may be pegged to oil price equivalent, or something in the same vein. Kvars are harder to agree upon as different countries will have different ways of billing. For some ship masters it is easier to run own generators for this reason.
About hooking up to shore power, I have not been involved.

By the time you climb under the superstructure, open the shore power hatch, dry it out, meg the connections, dry it out again, meg it again, then connect the shore power cables, it took quite a while.
On the other hand, we were some of the last ones in going out, and among the first ones out coming into port!

Is a link to the QM2. Most big liners are electrically driven. PArt of the reason has to be so the layout of engine/generators and propulsion motoers can be arranged to maxamize the number of cabins you can put in, the other has to be it's cheaper and faster to build.

Hard to believe I look back fondly on those days now! I just remember that most had gone home before we could have the reactor shut-down.

And the Blue Crew did their own work, thank you!

Boomer crews do thier own work until something breaks and then the smurfs from TRF come down and replace the MG bearings or whatever.

The Grand Princess (one of the largest cruise ships) has 69 MW of ship service generators, so it definitely isn't a small project to provide them service.

They must use 1MW for margarita blenders alone!
