The NorEx started as I was already the head of the steel design dept, so I only did alittle of the center casing in the first phase, but after that I only managed the project but did not do design work -unfortunately.

A very basic question but what is the steel coated with to inhibit rust during the building of a ship. I would assume it comes coated with some material from the steel supplier. I know aircraft is coated with either a green or blue coating that is washed off with a high pressure hose. I know a little surface rust is easily dealt with prior to painting. I was just wondering after seeing your pics of the structure that the NorEx deckhouse modules will be sitting on.

All steel plates delivered to us are coated with a very thin primer. Thin to be able to weld though the paint without making to much gas and weaking the weld seams (pores and holes due to gas) but thick enough to withstand abt 1 year outside. For every weld seam done by a machine, the traces are grinded to allow better welding and thinner weld thicknesses, for manual welding no grindind of primer is done. Once a module is completely built, it goes in the painting hall, where it will be sandblasted prior to applying several layers of paint.

Markus,
Are the modules just being stored outside, or are there crews working outside, also? Those modules are looking a little wet in your photos; not fun when there's a dry shop right beside you!

Markus,
How are you protecting your welders from gases and fumes during the welding process? Are they using air purifying or supplied air respirators, or perhaps both types, depending on the type of welding in progress. I am assuming that FSG shipyard workers are supplied with and must use state-of-the-art respiratory protection. The same presumably applies to other types of protective equipment also.
Must your welders be clean shaven in order to safely use their respiratory protective equipment?

Normally we try to do any work inside our covered building halls. Sometimes space is limited and they have to work outside. Everything which will be preoutfitted can get wet - if there is something which should not become wet, like a electric device, then it will be built in later.
Re welding. Either our welders wear masks connected by a pipe to a filter on their back and/or they have a weld gas extraction system which they can position directly to the weld seam. We have a safety mananger on the yard who constantly checks safety and health care together with the yard doctor.
(and I don´t think the welders must be shaved... who wants to prescribe that? )

(and I don´t think the welders must be shaved... who wants to prescribe that? ) In North America health and safety rules require that users of most types of respirators and 'dust masks' must be clean shaven where the respirator/mask seals against their face. I would expect the same rule to be in place in Europe. It is required to ensure that the respirator gives the user the best protection that is possible.

Markus, in the foreground of the cathedral the deckhouses for the NorEx are making a lot of progress. I assume that the hull portions also there are for the Turkish vessel. Is that correct?

Yes, the only block for the NorEx is the rectangular one in the foreground. The rest in our cathedral are modules for the Turkish vessels. We have launching for the first RoRo on march 14th and for the second on June, 12th. So keellaying for NorEx is on June, 16th. I will try to post some pictures today.

That's really fast shipbuilding. A launch a little less than three months apart on those Turkish ships.

You can see this deckhouse block left behind the bunker-boat (some blue containers in front of it).

*Applause* I think I am more excited about the Nor-Ex than the Coastals even. But I keep saying that When will the deckhouses actually be welded together outside where they are being moved? When the mega block is lifted that will be quite an amazing operation.

Markus, Why is the superstructure for the NorEx being built outside in one big block? I guess what I am getting at is why go to the extra hassle of having to lift the thing onto the hull when it could all be built inside the assembly hall? There is probably some logical explanation, but at the moment it sounds like something a BC shipbuilder would do. ;D This sounds like how our Spirit vessels were built. Thanks and good work,

I think I mentioned it some posts ago already but I explain it again ;D BCF wanted to have the vessels as early as possible. As our building slots were full, we had to ask one of our clients to get his RoRo three months later. This is the time, we need to build the hull in our building hall. As the deckhouse needs extensive outfitting, we had to start very early with the blocks in steel construction. Then we put it outside and completely (!) outfit it with everything. Then in September 2008, when the hull is launched, we lift it onto the hull and then are able to deliver the ship beginning of 2009. If we would do it in our building hall, it would have taken longer on the slipway. But BCF was late in ordering so we had to make this arrangement. But you are right - it is not the optimum way of building a ship and there are some risk, when lifting a 1.200ton block onto a hull. But we think, this will work! -we will see in September.

Deckhouse block 2 has also reached its final building place

Markus, I remember you saying before FSG will need to bring in two additional floating cranes to lift this module. Looking at where the deck-house modules are being assembled, I'm guessing the plan proposed for the lift is to tie the hull up along side the dock (perpendicular to the fit out slips). Then the cranes will be anchored seaward, and the module lifted out and over the hull. Is my reasoning correct? 1200 tonnes is a BIG lift, though this size of lift is much more common place today than it was even a decade ago. Many prefab concrete structures and tilt up panels approach the 200 tonne mark as the engineers get more adept at designing them. As an interesting aside, the new "Skyway" section of the Bay Bridge in San Francisco had two 2000 ton lifts during construction. Link here.Edit: I forgot to ask about the module plan. I see from the webpage, modules 1 though 4 are in assembly (makes sense...1 and 2 are already outside ...) and the rest of the deckhouse is in the cutting stage. Will all the modules presently highlighted on the module plan be part of the super module? Additionally, will the sections presently noted as in the cutting phase be assembled once 3 and 4 are moved outside, or will they wait until the hull is being assembled? I guess I'm wondering how crowded the hall is getting with three ships under construction at once!

hm, I think the plan for putting on the deckhouse is little different. Lift the house up first with two cranes, sail away (a bit), have launching, put the vessel on the left pier (as seen from Gerhards view) and put the house on. Weld one day and put the forward and aft deckhouse on the next two days. And yes - our production is filled up 130%. At the moment working on vessel 734,735,736,737 and 748 in production and vessel 738, 748, 737 and two projects in design offices... now I go home ;D

Okay. Thanks Markus, that actually make a little more sense to me. I thought what I reasoned out would be an awkward pick for the cranes because of the additional reach required. My method would likely have required larger cranes than the procedure you proposed.
Now, if I have this correct, there are three deckhouse super modules, aft, centre and forward, all will be assembled and in some stage of fit-out prior to keel-laying. Are all three approximately the same mass?

The middle segment appears to be the largest made up of the 4 deck modules that make up the middle of the ferry. All in blue and will be welded together outside. The wheelhouse deckhouse and the aft deckhouse are the ones still in red in the module plan on the FSG site under RORO's grow.

The fore and aft block will be built in Poland as it was done for the Coastals. The middle block is about 1200 tons completely outfitted and the aft and fore are around 600-700 each. All blocks will be completely ready for launching, only the small area in the joint will be left blank. some new pictures from the two houseblocks together: picasaweb.google.de/markus.brinkmann/NorthernExpedition

Markus, Correct me if I'm wrong ; the modules highlighted in red are the components being built in Poland. Have I got this straight yet?!? ;D
