Are you sure that these vessels will be deployed in the North Sea? Not exactly deep sea exploration. North Sea is pretty shallow.

I have been on a few of the largest tow outs of permanent North Sea platform from Stavanger in the early eighties and I have been installed in installing a floating storage and production vessel of the coast of Gabon or Congo. That one was a converted super tanker. Mind you what we called a super tanker in those days seems to be less than half the size of this thing! Absolutely colossal!!

On all our larger tugs we had four auxiliary engine to provide electricity. Next to that we had separate auxiliary engines that drove dedicated generator that would power the bow and stern thrusters. They take huge loads and the load can vary considerably in a short period, so you don't want them to draw from the main grid. On the AHT we also carried various bulk cargo, like cement for the oil rigs. Huge tanks that got pressurized and essentially you would blow the cement from the tank into a hose into a tank on the rig. The compressors were sometimes electrically driven, but the larger ones tend to have their individual diesel engine. So here's an example for a AHT: 2 Main propulsion Diesel 6000HP each 4 Auxiliary diesels for generating electricity 750 HP each 2 Auxiliary diesels for driving bow and stern thruster 1250 each 3 Auxiliary diesels for driving the bulk compressors Althought the very large two stroke low speed engines are the most efficient diesel around and can be coupled directly to the propellor they have one very notable disadvantage. They are absolutely staggering, monumental BIG. That's not such a problem for say a tanker, or a container ship. But for a RORO ship, a cruise ship, a tug, an AHT, a dredger, there is simply no room for such large engines. One of the reasons the medium speed four stroke engine made their entry into naval design Jeroen
Hi Jeroen,

Nice to see a die hard offshore man in this forum. Was in Northern Europe / Baltic till early last month on board a Vsl doing drilling and core sampling in the Baltic Sea, refreshingly so, not for the oil and gas industry but purely scientific research ! Have spent some time on anchor handlers as well but nothing close to what you have.

Cheers.

I've read your previous posts - I'm sure you talk from experience and I talk with reference to some conversations. I'm sure about vessels being designed for Deep sea exploration though. what part of the ocean, you know better.

Just came across this very interesting youtube video. I have never sailed with these sort of engines. I know there used to be a few manufacturers who tried out this concept. It never took on. I was told they were too complex in the end. Looked good on paper in the design stage, but difficult to maintain.

Still, it makes for a very unusual design and at least this is one engine where you can see parts, lots of parts, move!



The next video is interesting too. Overhaul of the turbo. If anything it gives you a good idea how large these turbo's are compared to what you might find on a car or even a truck. I've done this job myself a few times.



Enjoy

This thread just reminded me to complete the review of my last ship which is lying in the assembly line. I couldn't upload pics due to the slow net on board. Now that I'm home I better get it completed.
This is a new ship with the new "Fuel Efficient" ME Series engines. It's not as big as the Kimolos Warrior though. Just 183 m in length and 30 m wide.

Wow what a place to be. After reading the complete thread I have certainly developed a liking for ships.

BTW It seems Mr. Vijay is missing on this thread for long time. Hope he is doing well.

Hi,

A few pictures of a couple of my ships (both were VLCC's) in drydock in Dubai and Zhoushan, China.

thanks

Wow, fancy parking! "Five feet to the left... Ten feet forward... five feet... one foot... three inches and... stop!"

How do they do that?

Hi Guys,

I am posting some pictures of a ship i was on quite a few years back, and on a voyage to Tianjin (PRC). The weather was very cold and it was snowing, a day prior arrival. During night the vessel was shipping seas, as it was fully loaded, the water froze up due to the very low temperature, and it was sight next day morning. the picture says it all.

Yes, pretty precision job by the dry docking pilot, but then they do this a lot, and its a routine job for them.
thanks

Incredible ice pictures. Can this much ice affect the stability of a ship?

I seem to remember that icing can cause capsize and loss of fishing vessels.

Yes, it can. However in our case it did not. The crew had to break it with hammers, as we reached port next day, but we were lucky to get a days anchor, due which we were not off hired. This was a very rare case of icing, i have gone by the Bering Straits, and not faced any such problems. But, it was a sight which i had bever seen and never will again.
