On the second day of our cruise we attended the Captain's champagne reception. All of the ships officers were available to chat with and I had the opportunity to speak with one of the technical officers. I asked if I could get a look at the engine room and was informed that there was a formal tour available for only 16 people. The following day I was put on the list and waited to see if I had been cleared to go on the tour. Luckily, I was selected and attended the tour on the last sea day. We spent 3 hours with various crew members and saw the inner working of the whole ship:
1. Backstage:
We were greeted by the "Marcie" (Stage Manager) of the ship and saw the mechanics of the stage, the automation controls, audio and video management tools and dressing room available to the production crew. An interesting fact is that video of each production is analyzed to correct any missteps of the dancers and performers to advise them and correct any problems.Dressing Room for Performers
2. Crew Quarters:
Crew members are housed in various state rooms depending on their crew status. Rooms are located on deck one and two and are accessible from "I-95", the main roadway that runs 1100 feet down the center of the ship on deck 2.
Some are 3 to a room, some 2 to a room and the ships officers all have there own single rooms. 30 different nationalities are represented among the crew. Internet rooms and lounges for relaxing are located throughout the crew areas.
Several eating areas and crew bars are available to the crew.
Just like the passengers 3 main meals and late night meals are available. Off duty crew members can have a beer or a glass of wine or liquor but anyone caught with a blood alcohol level of .05 or greater will be dismissed and let off at the next port. This could be a problem for our group!
3. Supplies Area and Meat and Fish Prep:
We saw the areas that the thousands of pounds of groceries and supplies are stored. The meat and fish preparation areas were busy handling fresh lobster and rack of lamb for the evening meal.
4. Engine and Systems Monitoring Room:
After a security check and individual body scan we were permitted entry to the ships systems monitoring room. This area is crewed by 2 engineering specialists and includes about 20 computer monitors and about 40 live video feeds of the various mechanical services on the ship.
Logs of all systems are constantly recorded and manually logged. The crews work 6 hour shifts and typically are onboard for a 6 month contract.
Everything on the ship is powered by 4 main diesel generators backed up by 3 smaller units dedicated to essential services.
While the ship is underway, typically 2 main generators are running and supply the two propulsion units called "Azipods" with enough power to run at 22 knots. If the maximum speed of 24 knots is required due to weather, tides, sea conditions or schedule all four generators must be operating. The ship can run with only one generator and achieve 12 knots. All in all, there is quadruple redundancy for most systems on-board which is much like a 747.
5. Mooring Deck:
This area manages all of the shore lines and the main anchors. An interesting point about use of the anchors is that they cannot put out all of the anchor chain due to the weight.
A maximum of 7 seconds (About 1000 feet) with the anchor freewheeling out is the max weight the winches can retrieve the tremendous weight to bring the anchor back in.
6. Navigation Bridge:
The Greek Master of the ship greeted our tour and gave us an overview of the bridge from the Port side bridge extension about 24 feet outside of the main ships hull. There was a 4 foot square window in the floor which the crew can look down at the water from. The captain was very leery of standing there!
The second-in-command took over and explained the controls and main computer monitors on the bridge.
The Azipod system for the main propulsion make the ship very maneuverable. By rotating the two Azipods 360 degrees they can move the stern of the ship in any direction avoiding the tugs required by conventionally powered vessels. The Bow of the ship is maneuvered using 3 Bow Thrusters which can move the Bow horizontally in a Left or Right direction.
In addition to at least two navigation officers on the bridge when underway there are two lookouts posted at all times observing traffic and the water below. The navigation equipment and systems monitoring capabilities are similar to what you would find on a 747 jet.7. Galley Tour:
This tour was much the same as Gerry's experience but we had the head Chef leading the tour. They were preparing for lunch on my visit to the Galley.
