Back to work

We left the Besiktas shipyard early Friday evening, then spent the night waiting for a Pilot to guide us through the Bosporus Strait (http://www.worldatlas.com/aatlas/infopage/bosporus.htm). I was actually quite glad for this, as it allowed me the chance to observe Istanbul, the Strait, Europe and Asia as we sailed north from the Sea of Marmara to the Black Sea. However, the weather is a cruel mistress and didn't quite deliver what I was hoping for...

Right, let's see if I can get the image insert to work. Unless indicated otherwise all text refers to the picture above that text.

This was the view looking aft from the Bourbon Hector's bridge. Off to the right (boat port), just below the flag, is about all I could see of Turkey for about a week. At times even that was obscured with the eternal fog/smog that seems to be hanging about. Not sure if it's the change of seasons or pollution that causes it, but we just aren't getting the clear, distant days I'm used to.

The weather also isn't something I'm used to (anymore). I've gone soft working in African tropical waters for the last 4 years - the 15-20C days we've been having here almost seem cold! I'm better off than the Phillipino crew aboard however - they still don balaclavas and thermal overalls when venturing out. There is hope for improvement though - we've had a few semi-sunny days (which are quite warm), and sooner or later the cold wind from Siberia has to dissipate...

On this picture you can also see a bit of our ROV system. The red thing standing upright on the right is the A-frame. Just below it is the ROV (all yellow on top), the to the left is the TMS (Tether Management System) that normally fits on top  of the ROV and holds about 400m of tether. A bit more to the left is the winch holding 3500m of armoured umbilical. At this stage they'd only just completed the supporting steel work for all the structures so nothing is connected together yet.

This was the view to our starboard. That's a RoRo (Roll On, Roll Off) used to transport cars and the like. This pulled in to the dry dock one evening, the dock was emptied, and 46 hours later this is what she looked like. Stripped down to metal, with undercoat applied. Apparently they can turn around a vessel of this size in under a week - hull completely stripped down and repainted.

Note the little white dot beneath the hull.

That white dot is a man's safety hard-hat. The drydock is about 9m deep. This should give an idea of the size of the propellers and prop shafts used...

Here you can see some more of the system. This was just prior to leaving the dock, so it's almost complete. Well, as complete as needed to be for us to leave the shipyard and set sail for our  "working" port -- all the steel work was welded down and tested to be good (to a 12 ton load) and the workers had done a stirling job of applying some paint to the bare metal for us.

Although not fully connected, here the A-frame is almost where it would normally be, and the TMS has been connected to the umbilical. The umbilical is what takes the load of the system - basically it's three layers of steel wire counterwoven around a core of 17 copper conductors and 12 optical fibres. The conductors carry the electrical power (at 3000V), while the signals (video and control) are carried over the fibre-optic system.

The tether on the TMS (referred to earlier) is a lighter weight version of the umbilical, without the three layers of wire armour. This gives us better range on and controllability than if we had to operate off the umbilical only. A 2500m catenary when operating from a vessel out here would also be a nightmare to manage around any obstacles. The TMS also "disconnects" us from the vessel's movement, i.e. the boat can pitch and roll as it wishes, bu the ROV (once away from the TMS) will remain steady. The operators still sitting in the control van on the boat might not be so steady on their feet if the boat's bucking around really wildly though!

The two containers you can see are the workshop (to the left of the picture, boat starboard, and the control van (bottom of picture, boat for'ard). That's pretty much the layout of our system - updated pictures will follow once we're operational and "normal".

Here we've just left the shipyard. our (comparatively tiny) berth is just visible directly behind the boat's stern. As you can guess there wasn't much scenery visible with all the hulks of steel around us...

We cast off the ropes around 19:00 - which I though far too early to sail through the Bosporus Straits in daylight. Indeed, if all had gone well we would have sailed north around midnight, but we only picked up the pilot to gude us through the Strait in the early hours of this morning (Saturday morning).

View from our cabin porthole this morning. Yep, that was the weather in Istanbul today - grey, damp, and quite chilly...

Europe to the West...

Asia to the East.

There are a few more misty shots of various highlight along the shore as we sailed north, but none really worth putting in here I'm afraid. I'll try uploading a collection to Facebook sometime.

I'll leave with a last two pictures - a self-portrait (taken early in the morning, pre-coffeee!), and another of one my co-workers, affectionately called Shrek...!

Me...

And "Shrek"! :)

That's all the news for the now. We're due to do our first dive (a test dive) tomorrow. So far everything seems OK, just hope there's no hidden leak that's going to drown or sink the ROV/TMS! Once the dive's out the way we have a million other little things to attend to, including cleaning and painting all that lovely new steelwork... *groan*

The boat itself is quite nice, and the crew that's currently here are good people (although very mixed). Captain and Chief Mate are French and Brittany (French...), the Chief and Third Engineer are Polish, the Second Engineer is Slovakian. Two other bridge officers and the deck crew are  Phillipino. The ROV crew is a South African (me!) and two Brits. A proper international bunch we are! :)
