"Fiery" hot trend on Carnival cruise ships

Carnival Triumph ER fire
Sorry about the lack of posts lately, been busy with fathering / home duties... just wrote the comment below as a reply in the forum, but for those of you not following the discussion on the Carnival Splendor and Carnival Triumph fire, and dead ship scenarios over there, it may be of interest to you.

These are major casualties as far as far as I am concerned, and should be properly investigated and reported. I am not sure what Bahamas will do as the Triumph's flag authority, but Panama has swept the Splendor matter far under the rug, probably under the building foundation for that matter. I can't find a single mention of an official incident report or investigation of the Carnival Splendor.

A brief overview of large cruise ship propulsion system...

On the Fincantieri built ships I worked on (from the same shipbuilding company as the Triumph and Splendor), which I don't believe there is anything different or unusual about them from Carnival's, except maybe a little bit of the layout, the power system / propulsion system consisted of 5 Zulzer medium speed engines (12.6 MW each) as generators sets, producing 6600 vac. The engine and alternator were in the same compartment, located in two separate engine rooms (2 in aft er, 3 in fwd).

Power develop from one engine room went into one switchboard room (two main switchboards in two separate rooms). Each switchboard fed, primarily, the propulsion motors and hotel load, the propulsion motors were in another separate compartment.

Each propulsion motor (~20MW) has two sets of windings; if you were to lose a component, you could still get half motor power. Plus each winding was driven by a separate switchboard - winding one of each propulsion motor - fwd switchboard, winding two - aft switchboard. Being a variable speed propulsion motors, each winding was driven by its own SCR driver (frequency drive) and its own propulsion transformer.

Like all propulsion systems, the controls would be from various WH locations, ECR, or in the ER (local). This is not an abnormal system from what I have seen and heard, it is a very common design with lots of redundancy built in. I found the system properly illustrated on SAM electronics's website, linked. To have a view of the engine room I describe above, head over to the video page, where you find two tours, one for Disney ship built in Italy, and one for the Royal Caribbean ship, built in France. The french built ones, had even more separation of compartment, but the power plant was nearly identical in scope and operation.

To have two accident occur in a short time frame, that disabled two passenger ships of this age and size, is quite scary, due to the fact that passenger vessels now, are mostly identical in power plant package. To not issue proper accident reports on these incidents is extremely worrisome, as we may have major design issues, or operational vulnerabilities underlying both casualties (that we know of) that are not being addressed because they are not being communicated.

The US's NTSB and USCG is "helping" in the Triumph investigation, but the Bahamas Maritime Authority is supposedly the lead agency; judging from their website, and its lack of prior investigation being available to view, it does not look like we will hear more of this major casualty. I cannot find any mention of a report, completed or underway, from the Panama Maritime Authority either on the Carnival Splendor. 

Here is some other interesting background on the Splendor, from a lawyer, but still interesting. Here's a wider piece on the Splendor, a public relations class assignment, from the Arthur W Page society, a non governmental public relation group. Here's quote from that piece...
CEO of Carnival - Gerry Cahill
Gerry Cahill, CEO of Carnival Cruise Lines, later confirmed that the fire was a result of a catastrophic failure in one of six diesel generators. Cahill said he doubted that any of the other ships in the company’s fleet were at risk.
Ooops. I guess his doubts should not be really trusted. He's preside over the Carnival Splendor and Carnival Triumph fire and subsequent "dead ship" leaving around 9000 people stranded. Of course the Carnival Group corporate media relations people have also dealt with numerous other disasters like the Costa Concordia, Costa Allegra, etc. etc. and that's just in the last three years. Safety first, mmmmm.

WMI gets hammered

Earlier this month, and with the full support of the community behind it, Western Maritime Institute (WMI), began construction on their brand new student housing facilities. The building located next to the main institute building, nestled under a canopy of large trees, will initially house eight students attending the school for maritime training. Anticipated to open in April 2013, the new facilities makes a logical addition to the growing 6 hectare campus, located near Nanaimo, on beautiful Vancouver Island.

Students enrolled at WMI will be able to stay at the new facility, saving them from commuting and those extensive associated costs. The new student accommodation building is professionally designed, fully built to code, and will feature eight study cabins. Each room will have its own outside entrance and private bathroom; the units also have extra sound dampening built in. The building is covered by an all around veranda, to aid in relaxing after an intense day learning
Like a ship, common laundry facilities and bed linens will be provided. Cooking area is provided, adjacent to the student lounge in the nearby main building. The lounge will feature an entertainment center, and serve as a place to socialize. Wireless internet access will be provided at no extra cost. 

WMI advises that room rates will start at $38 per night for those people staying 28 days or more. Weekly rates will be $50 per night and short stay accommodation will cost $60 per night. For those who prefer not to cook their own meals, the nearby Timberland Pub offers meals for WMI students, costing $50 per day. The meals packages consist of a cooked breakfast, packed sandwich lunch, and dinner - taking one more worry away from students.

Taking maritime specific courses in Canada will now be most accessible at WMI. The Nanaimo Airport (YCD) is five minutes away, and  serviced by Air Canada and Westjet; fly in fly out training packages can be more easily budgeted for by companies. The airport is also serviced by Greyhound bus service, which runs numerous buses up and down Vancouver Island, daily. The campus’ close proximity to BC Ferries terminal(s) to the mainland, and the Island Highway, connecting Victoria to Port Hardy, allows easy driving access, with plenty of free parking on site.

The lower overall costs of accessing highly specialize maritime training courses will be more manageable for seasoned and aspiring mariners. I believe it is the first maritime institution in Canada to offer these kinds of facilities on site. Attached, are some pictures I took a couple of weeks ago, last week when I drove by, the roof was already up, with construction progressing rapidly.

Western Maritime Institute is locate between Nanaimo and Ladysmith on Vancouver Island, in British Columbia, Canada. They offer, primarily, deck certification training and the full suite of Marine Emergency Duties (MED) and related TC / STCW95 approved training onsite - including advance firefighting and rescue craft.
