Engine Room Tour: A Peek into 50 Let Pobedy’s Belly

Friday, 11 July 2014 (Part II)
Barents Sea

Remember those helicopter groups we signed up for?  Well, these groups weren’t used just for heli ops, but for other events and activities as well.

One such activity was a tour of 50 Let Pobedy’s engine room, including a peek into the reactor compartment and a visit to the control room.  These tours have been taking place since our first day at sea.  Our turn to travel into the deep recesses of the ship finally came today.

Vladimir Judin — Chief Engineer — speaks to us about the technical aspects of           
the ship before taking us down to see the inner-workings of 50 Let Pobedy.              

The tour started in a conference room where Chief Engineer Vladimir Judin spoke to us — through Irina, the translator.  Funny coincidence — the suite we’re staying in is normally where he is quartered … we assured him we would be leaving it in good shape for him to take up residence again after we disembark tomorrow.

Vladimir covered some of the technical aspects of the ship and answered our questions before leading us down to and around areas of the ship that are normally off-limits to passengers.  The high level of noise from the machinery made it impossible to speak or hear anything once we began the tour.  No worries … Vladimir had covered the essential points during the presentation … and Irina was on hand to hold up informational placards to advise us of where we were and what we were seeing.

We were allowed to — in fact, encouraged to — take photos throughout the tour … with two exceptions.  To comply with international regulations, no photography was allowed of (1) the reactor compartment, which we viewed through windows in the central maintenance room; and (2) the state-of-the-art central control room, which we were allowed to enter for an up-close-look at the wall-to-wall equipment used to monitor the reactors and other machinery essential to the operation of the ship.

This post is going to consist of some of the points covered by Vladimir in the conference room — in no specific order — with series of photos from the tour interspersed throughout.  For additional information about the nuclear power plant, click here for information from the RosAtomFlot website.

Steering Gear Compartment

Rudder

Propeller Shaft

  • Keel laid in October 1989 at the Baltic Shipyards in Leningrad; construction completed in 2006 … by then the city had reverted to its original name of St Petersburg; went into service in 2007.
  • 160m long, 30m wide, 11m draft (525/98/36 feet); 23,439 registered tons; 75,000 horsepower.
  • Top speed in open waters: 22 knots (25 mph/50kph); continuous speed through 2m thick ice: 2 knots (2.3 mph/3.7 kph).
  • Main principle behind building nuclear-powered icebreakers: reliability — at least one back-up for every system; 2 reactors, 2 turbines, 6 electric engines, 3 propulsion motors, 3 propellers.

Propulsion Compartment

  • Double-hulled; inner hull — 35mm (1.4 inches) thick at the bow and the stem; 55mm (2.17 inches) thick amidships; outer hull — 48 mm thick (1.9 inches) argon welded armor steel overlaid with 5-7mm (.2 to .3 inch) plating of stainless steel where the ship meets the ice (ice-belt); 4m (13 feet) wide ice-belt all the way around.
  • Spoon-shaped bow has a 48cm (19-inch) thick cast iron prow.
  • Can remain afloat even if two adjacent compartments are flooded.
  • Large number of ballast tanks provide additional protection for the interior of the ship.

Turbine Compartment

  • Reactors engineered to withstand collision with another ship of similar type up to speeds of 15 knots (17 mph/28 kph).
  • Reactor rods replaced every 5-7 years.
  • Used nuclear fuel stored aboard a special holding vessel for 2 years; discharged and stored ashore at a special facility for another 3 years; then transported to a plant in the Urals for recycling.
  • Used reactor water kept in special tanks aboard the ship; discharged and stored in port.

Electric Generators

  • The amount of time the ship can remain at sea limited only by the food supply — usually 7 months when not in passenger service.
  • Two desalination plants capable of generating 100 tons of fresh water daily; as of the time of the tour, still consuming what is left of the 680 tons of fresh water taken on in Murmansk on 1 July.
  • 70 people work for the chief engineer; 3 watches of 4 hours each; 8 hours of rest.  Education requirements: 5 years of university; 1 year of specialized training; refresher courses every 5 years.
  • Use about 1 kilo (2.2 pounds) of uranium per reactor/per voyage; both reactors in operation at all times at approximately 25% capacity going through open water and 100% capacity in thick ice.

Desalination Plant

The tour was very interesting; I just wish they had been conducted in single groups of ten, instead of merging two groups for double that number.  I can understand, however, the reason for combining groups — multiple tours daily would be a bigger burden on the crew of this working vessel.  Also, the pace was necessarily fast, so I was unable to take detail shots and had to be satisfied with general ones.

Regardless, I am grateful we were given the opportunity to see the inner workings of 50 Let Pobedy.  It really was fascinating to see all this.

Southbound for Murmansk … Day 2

Friday, 11 July 2014 (Part I)
Barents Sea
Position @ Noon: 71°48’ N / 36°59’ E
Outside Temperature: 45F / 7.2C … it’s a heat wave!
1,092 NM (1,256 miles / 2,022 km) from the North Pole

You’ll never ever know; if you never ever go.
— A Bob’ism —

We’ve put our clocks back one more hour — we’re now on Moscow time with the ship’s crew.  But I am not getting too excited about the gain; we’ll be losing it again tomorrow when we arrive in Helsinki — the end point of this adventure.

Woke up to calm seas again this morning.  The movement of the ship was barely noticeable all day.  The navigation channel shows us at the mouth of Kola Bay at the moment — 11:16p — and it feels like 50 Let Pobedy is just inching along.  My guess is that we are either waiting on the Customs officials or the high tide — or both — before putting on speed to continue on to Murmansk.

The temperature was noticeably warmer much of the day, but not once did we see the sun.  We were enveloped in fog — all day.  I did wander the decks a few times, but I left my camera in the cabin since there was nothing to see.  Any filler-photos in this post will be details from inside the ship for a change.

At the conclusion of a trip, we usually just toss everything in our bags, worrying only about balancing the weight to meet airline baggage restrictions.  Not this time; with post-expedition days in Helsinki ahead of us, at least some of our clothes needed to remain serviceable.  So we took a bit more care with this chore.  Now the bags are packed and sitting outside the cabin door, ready for the crew to pick them up at some point in the wee hours — we won’t see our luggage again until we’re at the airport.

There was only one lecture on today’s agenda — Conrad spoke to us about the Whales and Seals of the Arctic Ocean … a topic near and dear to my heart.  He started out by telling us a “whale of a tale” … about Sedna, the goddess of the sea and marine mammals in Inuit mythology.  As with all such tales, different versions are told by different cultures.  What stays the same in all the stories is that her father takes her to sea in his kayak after she dies and consigns her body to the depths.  There she becomes a goddess who must be placated by hunters so that she releases the marine creatures from the depths of the ocean, thus ensuring a successful hunt.

[Click this beautiful Anthony Galbraith image of Sedna for one version of the myth.]

The next part of his talk included general information about whales, as well as information specific to some of the species.  I’m going to outline a few of the general points since I can’t cover the entire lecture in this post.

  • Like elephants and great apes, whales and dolphins are sentient beings; they have cognizance and can solve problems — therefore, we feel a close affinity with them.
  • Hippopotamus are the closest living relatives of whales (more here).
  • Right whales, the rarest of all large whales, were easy pickings for whalers because a thick layer of blubber kept them afloat after they were killed — hence they were the “right” whale to hunt.
  • Whales are mammals that live in water — warm blooded; breathe air through lungs; nurture their young with milk.

Compare the size of these cetacea to the lone diver at the bottom right.
The Blue Whale (bottom left) is the largest existing animal on earth.

  • There are two types of whales — baleen (12 species); toothed (67 species).
  • Baleen whales (except for bowheads) migrate for food; they use the baleen fringe in their mouths to trap their food when they force the water out through the baleen; where there are baleen whales, there is krill; they ingest 4% of their body weight in a single feeding … that’s three tons per day for a blue whale; they are lunge feeders (except for right whales … they skim the water for their food); they have two blowholes.
  • Toothed whales are predators … stronger swimmers as evidenced by their skeletal structure; they have a single blowhole; with the exception of the sperm whale, they are smaller than baleen whales; they catch their prey with their teeth, but swallow it whole.

We had some free time after Conrad’s presentation.  Mui joined shipmates in the library for coffee and a chat.  I used the time to photograph some of the ‘timeless’ details around the ship before returning to the aft saloon for Val’s presentation titled Bi-polarism Quark Style: Other Polar Destinations.  Since we already have our travel plans booked through 2015, I went to see the images she used in her presentation more than anything else.  That said, I did fall in love with a new itinerary that Quark is testing in the Antarctic this season … sure hope they repeat it in a few years’ time.

Communication devices haven’t come a long way on 50 Let Pobedy — but they get the job done.

For lunch, we joined an interesting mix of Japanese, Chinese, Pakistani, Canadian, and Spanish passengers.  Conversation wasn’t always easy, but somehow we all managed to get our messages across.  Countries could learn a lot from a patchwork of international passengers traveling together.  I had the baked potato with mushroom ragout as my main course; Mui went with the fish and chips served with aioli sauce.  Dessert was walnut brownies — which we ordered with vanilla ice cream on the side and started a trend in the dining room by doing so ;-)

When 2:00p came around, we found ourselves having to make a choice — see a documentary or go on a tour.  The documentary — Pandora’s Promise … exploring the role of nuclear power in the modern age.  The tour — 50 Let Pobedy’s engine room.  We decided that we could rent the documentary when we get home; the tour we would not have a chance to do after disembarking the ship.  Decision made easy.  Here’s a teaser photo … the rest will be in a separate post ;-)

This is all part of the gear that steers the ship.

Our afternoon continued with the Disembarkation Briefing.  Alex prefaced his words by paraphrasing an oft-quoted statement … “Alex proposes, Customs disposes.”  Ahh yes, we know how that works, and will remain flexible.  In any event, the ETA for Murmansk is 0700 tomorrow.  The bridge and the bow will both be off limits to passengers — the former … starting this evening; the latter … during mooring operations tomorrow morning.  Disembarkation is expected to commence after the transfer busses gain entry to the RosAtomFlot Base around 9:00a.  If all goes according to plan, we will be winging our way to Helsinki by 1:00p.

The irony of seeing a top secret dispatch from a US navy vessel on a bulletin
board aboard a Russian ship doesn’t escape me.  Good news — the message
is nearly as old as me, so the classification doesn’t matter anymore!

Our Quark package includes a night in Helsinki before everyone goes their own way.  Alex continued his briefing with information about the logistics in Helsinki, and wrapped up with the expected temperature in Murmansk … 50-68F (10-20C) and Helsinki … high of 66F (19C) — a veritable heat wave!

Participatory art demonstration with Team Narwhal.

The evening’s farewell activities began with cocktails in the aft saloon.  No formal attire needed — a good thing since we’ve given up traveling with formal wear on pleasure cruises, let alone bringing them on an expedition voyage.  In addition to toasting the success of the trip with the Captain, the event included a preview of the expedition-in-review slideshow compiled from photos submitted by passengers and those taken by Dr Sam, who was tasked with being the official photographer.  She and Kiff did a great job of putting it all together; we’ll get copies of the DVD when we pick up our passports tomorrow.

Fellow-passenger Annie takes this photograph of us, as Mui …

… photographs the expedition team posing with Captain Davydyants.

A very nice surprise that wrapped up the cocktail hour was the gift of 50 Let Pobedy pins to every passenger.  The gift was announced by Alex, who read a letter from the “givers” — a passenger couple who wished to remain anonymous.  Their identity did not remain a secret for long, however, as whispers of who they were circulated around the room in short order.

Thanks for the pin … I won’t reveal your names here, but you know who you are.

The farewell dinner was a bitter-sweet affair.  Conversation was jovial much of the time, but moments of sadness crept in when we reminisced about the past 10 days.  Between all the conversation and the frequent photo ops, we didn’t really do justice to the meal itself — which, for us, consisted of appetizer tacos served with guacamole; seafood platter with couscous, tomato and champagne sauce (for me); and rib eye steak with pepper sauce, served with a side of vegetables and potatoes (for Mui).

The photo op with our tablemates …

… had some party-crashers from neighboring tables the second time around.

Dessert was a special surprise tonight — a traditional ending for farewell dinners on pleasure cruises, but a first for us on an expedition voyage.

Baked Alaska — with sparklers instead of the traditional flames.

And thus our last day on the ship is all but wrapped up.  We had a nightcap in the Victory Bar before calling it a night.  Not sure anyone is left up there now — it’s past 11:00p and the bar is closed due to Russian customs regulations.  I’m going to write the post for the engine room tour and then I’ll be off to bed … when we wake up, we’ll be in Murmansk.

Southbound to Murmansk … Northern Barents Sea

Thursday, 10 July 2014
Barents Sea
Position @ Noon: 77°21’ N / 49°26’ E
Outside Temperature: 34F / 1.2C
Thickness of Ice: There is none!
759 NM (873 miles / 1,406 km) from the North Pole

A ship in harbor is safe, but that is not what ships are built for.
— John A. Shedd —

I think it was around 3:00a when I finally turned out the light last night this morning … and thus brought closure to an active day of landings and interesting sights.

There was no wake-up call to greet today — an opportunity for everyone to take it easy during what is the first of a two-day crossing back to Murmansk, Russia.

And that’s exactly what I did — starting with sleeping in until 8:30a.  Having gone to bed well before I did, Mui was already up and at ‘em.  I shooed him off to breakfast, asking him to bring me a bagel with cream cheese, and a plate of fresh fruit … which I am eating even as I begin to write this post.

Before I get on with the story of today, I want to touch upon a conversation I had with some shipmates last night in the Victory Bar.  On the surface, the question that initiated the conversation was an easy one — how would you compare the Antarctic to the Arctic … or vice versa?  The responses around the table — from those who had been to both polar regions — didn’t come as a surprise as it reflected what I had heard many times before.  My response, on the other hand, took some off guard … I think.

How we ended yesterday — with sunshine filtered by clouds …

… how we ended today — with thick fog!

When we were planning our first Arctic trip — which happened to be to Svalbard, in the Norwegian Arctic — I was told repeatedly that since we’d been to Antarctica, we were doomed to disappointment.  Hmmm!  I suppose if we had gone with that mindset, we might have been crestfallen.  But we didn’t … and we weren’t.  You see, we simply did not compare the two.  Rather, we looked upon the Svalbard voyage as an entirely separate polar experience … as a standalone ‘whole experience’ to be cherished and remembered as such.  The same holds true for our Greenland voyages, and for this one as well — just different … special … memorable … incomparable.

No ice anywhere around us today — this photograph of repeating
patterns was taken in northern Franz Josef Land two days ago.

To take it a step further, not only do we not compare our polar experiences, we don’t compare any destination … any trip — regardless of length or $s spent.  Each is different and special in its own way.  Thus making the "What was your favorite trip?" question impossible to answer — in case anyone has it in mind to query us in that regard ;-)

Alex on the P/A with a wake up call from an earlier day on this voyage.

Now to go out and play a bit … more later.

Later — the story of today …

Taking it easy extended to more than getting up late and dallying in the cabin this morning.  When I stepped out on deck I noticed that the fog was thickening quite rapidly.  There was a damp chill in the air.  And around us was nothing but open seas.  Not much to invite me to stay outside.  No matter — a quiet day indoors was exactly what the doctor had ordered.  I even gave my shutter-clicking finger a rest — while many of the pictures in this post are from today, I ‘stole’ some of them from previous days.

Just some of the instruments that guide our way on 50 Let Pobedy.

I debated going to the lectures — Colin gave a talk on Extra-Terrestrial Ice: Glaciers on Mars; Bob presented Russian Aspects of the Arctic Ocean; Norm’s topic was Global Warming — Climate Change.  I’m sure they were interesting, but I skipped all three.  Collecting my Kindle and laptop, I found a quiet corner in the library to read, and process photos for the voyage DVD — with so many passengers missing out on Cape Fligley (post here), I wanted to get my photos from that landing exported to share with my shipmates.

In addition to being our balloon pilot, Kiff is responsible for compiling the voyage DVD.

By the time I had uploaded the Fligley images to the laptop where all photos for the DVD are being collected, it was lunch time.  During our days in the ice, I frequently ate and ran.  Not today.  I took my time, enjoying the company of the fellow passengers with whom we shared a table.  The conversation was good — as was the food … deep fried calamari rings from the buffet; chicken schnitzel with potato salad (for Mui); orecchiette with smoked salmon in a creamy sauce (for ‘moi’); cranberry-banana smoothie (for dessert).

Chicken Schnitzel

Orecchiette with Smoked Salmon

After lunch, I went for a walk outside, but the damp chill drove me inside after a while.  A cup of hot chocolate to warm up, and then I joined Mui on a self-guided tour of the lower decks.  We stopped by the gym first.  We’ve not taken advantage of these facilities, but there has been a ‘sports hour’ led by a member of the expedition team every day — today it was ping pong with Timur.

The exercise facilities might be small, but they get the job done
for the ship’s crew … and for the passengers.

Our trip around the lower decks was not aimless — Mui wanted to check out the swimming pool and the sauna.  What makes the seawater pool interesting is that it is located below the waterline, allowing the reverberations from the engines to travel through the water.  Mui said the water ‘vibrated’ — sort of like those relaxation massage chairs one sees in airports these days.

Leaving Mui to his swim and sauna, I returned to the library where a special event was in progress — photo ops where passengers were striking a variety of poses while holding the Sochi Olympics Torch that 50 Let Pobedy carried to the North Pole in October 2013.  This was part of the traditional torch relay that precedes every Olympics.  Torchbearers from several countries — Russia, Canada, USA, Finland, Norway, Iceland, Sweden, and Denmark — participated in an approximately 3-mile (5 km) relay … the first ever at the Geographic North Pole.  (More info here.)

In keeping with tradition, the relayer — 50 Let Pobedy — gets to keep the torch.

Afternoon tea was preceded by an activity that brought home the fact that the expedition aspect of this voyage is all but over — the return of the boots and zodiac life jackets loaned to us by Quark for the duration of the trip.  Sigh!  All good things come to an end … like it or not.  To ‘drown my sorrows’ I skipped the tea and got myself a Baileys — hold the hot chocolate — and headed to the aft saloon for Bob’s presentation entitled Hunters and Trappers, Whalers and Sealers: Exploitation of the Living Resources of the Arctic.

Amongst the information I garnered from Bob’s presentation is the following association between ‘products’ and the animals that were hunted for such …

  • Blubber (oil) — walrus, seal, whale
  • Meat — walrus, seal, whale, reindeer/ caribou, musk ox, bear
  • Other Food — birds and eggs, fish, hare
  • Hides/Skins (leather) — reindeer/caribou, seal, walrus, bear
  • Pelts (fur) — fox, bear, reindeer/caribou, weasel/ermine
  • Ivory — walrus, whale, narwhal, mammoth 
  • Other Products — baleen (whale); antler (reindeer); wool/qiviut (musk ox); eider down (duck)

As abhorrent as the idea is to me, I can understand the need for indigenous people to hunt.  They did it to survive in the far north — they couldn’t have lived in the high latitudes without these products.  It was the food they ate … the resources they needed to make implements, to clothe themselves, and to build huts.  Subsistence hunting is still practiced in the Arctic.  There is a substantial difference between hunting for ‘need’, and hunting for trophy — I’m OK with the former; not with the latter.  OK — off my soapbox now.

In the brief time between Bob’s lecture and the daily R&B, I ventured out for a breath of fresh air.  Thick fog continued to surround us, but the light seemed brighter — perhaps I just wanted it to be so.  At least we had lovely weather up north — for days at sea, it really doesn’t matter as much.

Looking aft, or …

... starboard, or ...

… ahead — we’re fogged in!  No question about that.

Alex started the R&B by telling us that we’ll be arriving at the mouth of Kola Bay tomorrow evening.  We have to wait for customs agents to clear the ship before we can proceed further.  Oh, and the timing of the tide is important, too; has to be high tide before the ship can enter the bay!  We did get some bad news before Alex wrapped up — the gap between ship’s time and passenger time will be closing … we’re putting the clocks ahead one hour tonight; and will do so again tomorrow night.

The recap portion of the meeting consisted mostly of Conrad’s mini-lecture on the seabirds of Franz Josef Land, focusing on some of the adaptations as they relate to predation.  He also had a few brief words about our encounter with bowhead whales yesterday.  It is estimated that there are about 300 of these whales in the entire archipelago; that we saw so many of them (I estimated around 10-12 animals) yesterday makes our sighting all the more special.

From our very special encounter with bowhead whales yesterday.

Dinner was a special theme night — Russian — with the wait-staff dressed up in traditional costume.  Vodka shots were served to kick-start the meal — Mui got to double up as I can’t stand the stuff ;-)

Then came blinis — a type of pancake that dates back a thousand years or so.  They can be served with a variety of fillings … in our case, chopped onions, eggs, rice, sour cream, and caviar.  The menu offered three options for the main course — I ordered the baked fillet of salmon “Franz Josef” with puff pastry, white wine risotto, and beetroot; Mui got the beef stroganoff served with dumplings and broccoli.  We agreed that both was good.  To conclude, we ordered the “Swan” puff pastry filled with a vanilla vodka cream — yummy!

Clockwise from top left: blini, beef stroganoff, salmon “Franz Josef,” and cream filled “Swan.”

We didn’t dally after dinner — call it part of the “taking it easy” theme of the day.  When we entered the cabin, we found two black bags on the bed — one for each of us.  The notecard indicated they were a gift from Quark, intended for us to use to pack our parkas.  I think we’ll keep them as a souvenir and use them when we get home instead.

And that’s a wrap as they say in show business.  This is perhaps the earliest I will be turning off the light … tomorrow should be another quiet day at sea.  I’m looking forward to it.
