Last month, while on another successful rig move we had the pleasure of watching some very heavy lifts going on, now when I say pleasure, I mean in the geeky sort of way, watching a crane lift something is not everyones height of entertainment, but for me it’s cool, and even cooler when you think about this being done at sea, most of us have seen a crane on the high street getting ready to do a lift, the first thing the crane does after parking up and the driver having 3 bacon sandwiches and 4 cups of tea is to put out the stabilises, those things in each corner that slide out a meter or so and press down on the ground to level and steady the crane. The thing is you can’t do this at sea, you have to use ballast and one great thing to use as ballast is water.
This is the Saipem 7000 just after completing 4 very complex heavy lifts, one lift being 11,100 tons, thats 500 tons under the world record (which was done by the same vessel). To put that into perspective thats 4080 female Indian elephants. Now to get back to this ballast thing, the Saipem 7000 was fitted with two ballast systems: A conventional pumped system which could transfer up to 24,000 tonnes of water per hour using 4 pumps and a free flooding system. The free flooding system used 2 m diameter valves to open certain compartments to the sea thus trimming or heeling the vessel. This allows the vessel to lift cargoes from barges much faster than if just the crane hoists are used.
This was the second time I have seen a heavy lift vessel, funny enough the first time was the rig move just before this one when I saw the Thialf, this is the largest crane vessel in the world.
Just got back from another successful rig move, this one was a Jack-up out from Norwich, it first tried to move early January but could not due to the weather, after another two attempts failed due to weather again we finally got the weather window we needed, once the legs were up and water tight integrity confirmed we were on our way, a two day tow and we were at the standby location, a couple of days WOW (Waiting On Weather) here until another weather window saw us move to final location, we used sonar and GPS to locate our exact position and pinned the legs onto the three pre-installed gravel mats, three days of pre-load, this is filling the hull with water when it is a couple of feet out of the water so we get maximum weight on each leg, once happy we lift the rig to its working height, jump on a helicopter and are home for tea and biscuits.
Now I suppose you want some photos of it, sorry but due to restrictions imposed by my employer I can’t, but I am working on it.
However here are some from the British Virgin Islands, a wildlife theme this time.
Another industrial night scene for you, (well dusk anyway) this one is in Amsterdam, the vessel at the bottom of photo is the Sirius, a Greenpeace ship, just chilling out until they go and do their thing.
I like the way it’s very industrial with the cranes and jack-up, a container ship sailing out to open sea and the lone wind turbine as if to say, “Hey look we are Green”.
First the good news, I’ve had another photo published in a magazine called Interactions, it’s a photo of Archie (my dog) with xmas socks on, which I had placed on my blog.
Now the bad news, I have been told by my employer that I cannot publish photos of rig’s, platforms, & AHV’s, basically anything to do with the offshore industry without prior consent from the owner, so rigmover.com as we know it is no-more!!!! I was thinking of changing it to http://www.heylookatmydog.com or http://www.doyoulikemycar.com but thats just silly. So in the foreseeable future you will have to settle for photos of the sea and maybe the odd sunset, on which I’m sure you will get bored of very quickly.
I have a link to Interocean on my side bar, this is not the company I work for, Interocean use some of my photos on their web site.
This is very disappointing, as I’m sure I have passed on a little of what goes on out there, I have had some great feed back and I thank you all for that.
P.S. Don’t go to far rigmover.com will be back, in some form or another.
I’m back at work tomorrow, flying up to Inverness and then hire car to Invergordon, I’ve never stayed in the town of Invergordon before, always on a rig, so I might have time to explore a bit, If I do i’ll try a snap a few off and show you the place.
I’m joining the Maersk Resilient which is a large Jack-up, it’s one I was on a couple of xmases ago.
Here’s a shot of Invergordon from a rig’s point of view.
Here’s a shot of the Jack-up in the first picture I took a long time ago, I’ll be surprised if its still there.
Some of the locals just carry on as if nothing is happening.
Digging through some old photos I found a rig move we did out of Dundee, I haven’t spent any time in Dundee so don’t know much about the place except what I just read on Wiki and it does sound like a pretty cool place.
We joined a jack-up called the Rowan Viking, this was brand new and wasn’t long here from Singapore, however if I remember it did sit in Dundee for a few months before I joined, due to red tape.
It a pretty big rig, 264′ in length and 289′ wide and can accommodate 120 people and can drill to a depth of 35000′.
At last we are on our way.
And I couldn’t resist a HDR of Dundee.
I’m back on dry land after 14 days at sea, it was a good rig move, all went well and nobody got hurt.
This shot is from a rig move I was part of, starting in Amsterdam, we had a couple of days before we left and found this really nice steak house, we would order beers and steak and sit outside and watch the world go by, mainly on boats and bicycles, very relaxing.
Have a great weekend.
I’m having some problems with WordPress at the moment, I find I’m having to log on each and every time I wish to comment or ‘like’ on anyones blog, this gets really annoying after a while, so if I don’t comment I’m sorry and I hope they sort it out soon, I have contacted them and each time I do the responses I get is always the same, “turn on cookies” which I have done but its still the same but with the added hassle of around 40 spams a day.
This has been the first Christmas I’ve spent at home in 5 years and it has been fantastic. December is a busy month for us, last year while I was away I missed,(In order) My son’s birthday, our twentieth wedding anniversary, Christmas day, boxing day, my birthday, New years eve, and new years day. The worst thing was, the weather was so bad we didn’t do anything.
But it’s not all doom and gloom off-shore at Christmas, everybody knows that we are all stuck out there so we make the most of it, movies and games, go to the gym or just chill.
Christmas day lunch is to die for, last year we had two sittings, we were on the first, we took our seats, read the menu, had a choice of starters, followed by a large choice of main dishes, deserts were out of this world, all washed down with non alcohol beer and wine.
But the evening meal is when the staff onboard really go to town, it’s a cold buffet, I won’t tell you about it because I wouldn’t be able to give it justice, here is a shot of part of it.
This all goes on during 128 knot winds, 10 meter waves. now we are on a jack-up so we don’t move around that much but the noise from the wind whistling through the legs was really loud.
This photo shows the weather, these waves are suppose to be 10 meters high but the wind is so strong it’s keeping them down around 7 meters. I took this shot from the pilot house which is about 7 stories up.
After doing nothing for 28 days we were allowed to go home, the day after we left they decided to move, as they started to jack down into the water a weld on one of the legs failed, properly due to the very high winds and stress of the legs flexing. The jack-up was immediately towed to shallow water for repairs and checks on all the legs, a big job, here is part of one leg.
A month later and guess where I was, yeah back onboard, we towed it to where it should of gone and sat it on the seabed. Job done.
We have a fiftieth birthday party tonight (not mine) My birthday tomorrow (not fifty yet) then New Years eve, so have a great new year and I’ll post again next year.
****WARNING ENGINEERING GEEKY STUFF****
This is the jackup that was berthed next to us in Amsterdam, it’s a Jackup barge, properly built for wind farm installation, like the one I’m on, this is a DP2 class barge, DP (Dynamic Positioning) users GPS satellites to get a position and large thrusters to stay on that location, it’s accurate to about 10cm. Here is a shot of the complete barge taken from ours, in the shadow of our helideck is their bow (pointy bit on a boat) and you can just make out the bow thrusters.
Here is a closer look at the thrusters, as you can see these are lowered at the moment, in this position they can swivel 360 degrees giving great movability, when in transit the thrusters are raised for less water resistance, but the clever bit is the big holes, this is so when the thrusters are up they can still be used, by switching the large electric motors from forward to reverse the position of the bow can be moved in any direction.
For the last couple of days I’ve been having to sit outside on the stairs and connect to the wifi from the rig parked next to us, it was very slow and would not let me view some sites, so sorry if I haven’t been to yours lately. The thing is, I move rigs right, so when I join the rig it’s going to be moving, this normally means it’s going from one client to another, it’s seem really daft but when one client leaves they take everything with them, this includes the wifi, that’s why I sometimes don’t post, because I can’t. Now you know.
This is the thing I’ll be moving tomorrow morning, is it a boat or a rig? Well it sails out to location under its own steam, then once on location it lowers its legs and lifts itself out of the water, cool ah.
This is the one next to us, the one I’ve been stealing the wifi from. There has always been a problem with jackup’s, the legs get in the way of the cranes. But this is really cool, they have built the crane around the leg. (that’s the large round black thing with red and white on the top) I think that is an awesome bit of engineering, but then I’m strange.
Here is the same smoke stack as the Amsterdam post, but first thing this morning, not a breath of wind, you might have seen it on Instagram if you follow me, @rigmover
