Wisbech port colours

click photo to enlarge
There has been a port at Wisbech since the medieval period. Of course, inland ports (Wisbech is over 10 miles from the sea) made a lot of sense when land transport was so limited by the size of carts and the speed at which they could travel. The town originally stood on the River Ouse but when the mouth of this river silted up and it was diverted to King's Lynn, the River Nene was made to serve the town.

The port became prosperous in the 19th century following the drainage of the Fens.  The area was noted for the  largest grain market outside London. Ships from Wisbech sailed down the Nene to The Wash, and from there took agricultural produce up and down the eastern coast of Britain and across the North Sea. Returning ships imported a variety of goods but notably coal and timber, the latter from the Baltic region. Trade with the Baltic continues today as does the import of timber, some of which can be seen in the photograph. A fortnightly service runs from Wisbech to Riga in Latvia.

As we walked past the docks the other day the bright blue of the sky was set against the red of a crane and the yellow warning triangles on the flood defence gates. This conjunction of primary colours seemed a good subject for a photograph.

Red crane question

click photo to enlarge
A while ago I was on the street in Shoreditch, London, at 6.58 a.m. taking today's photograph. The EXIF details of this image show that to be the time. I have to say that it is not usual to find me taking photographs at that time of day, but it does occasionally happen.

What prompted the photograph was the angles in the composition, the crystal clear light that delineated the new (and terrible) hotel,the bright red crane next to it, and the backdrop of an azure sky. I liked the juxtaposition of the crane and its shadow with building, and the red on blue adds a blast of colour that compensates for the mushroom tones of the hotel's cladding.

As we waited for our rendezvous the crane driver came along to start his day working on the site below his machine. His first task was to climb the ladders inside the column of the crane to his cab at the top. This he did in a very slow and deliberate way, lunch bag over his shoulder, waiting for a couple of minutes at each stage, presumably getting his breath back. During the ten minutes or so that we watched he ascended about half way to his workplace. And, as we watched him climb, this question popped into my head - is there a toilet at the top of such a crane? If there isn't it's long way down and back up again to achieve relief! I recently consulted the all-knowing WWW in search of the answer and was surprised by what I discovered. Apparently built in toilets are rare. Climbing down and back up does happen. A bucket is often used. So too is an empty milk bottle. And someone has designed a "toilet-in-a-bag" for crane drivers who are caught short. So, not only is the job of such a crane driver lonely, it also lacks a workplace essential that most other people take for granted.

Wind turbine repairs

click photo to enlarge
There's nothing secluded or furtive about the generation of electricity by wind turbines. Not only are the windmills themselves very tall, white, often in groups and consequently visible for miles, they also move and so the eye can't help but notice them. And it's those eye-catching qualities that, in the main, cause them to be unpopular. I say "in the main" because there is a significant minority who like them not only for what they do - the generation of "greener" energy - but also for what they are. Such people see beauty, elegance and the future in these tall machines.

However, one characteristic of all machines, be they traditional or leading edge, is their capacity to fail, to break down and to require repair and maintenance. You can often see individual turbines completely still, looking like a sullen schoolboy who hasn't been allowed to join the game, facing a completely different direction from that of its companions. These are frequently accompanied by a white van parked at the base and an open door in the column signifying the presence of an engineer. Given the conspicuousness of wind turbines it follows that when any work is being done on them, it is obvious for all to see, and not just in the form of the van. I posted a photograph last year of workmen abseiling down the blades of a turbine as they went about their repair work

The other day we saw across the fields a large crane next to a turbine and immediately knew it was receiving care and attention. On the following day I went to see what was going on and heard that a gearbox had been replaced. The crane that is capable of reaching the hub of one of these monsters was moving objects about on the ground in preparation for more work so I wasn't able to photograph it at its full height. But, I did get a distant shot of it at work. I also took a photograph of  a couple of men busy on the nacelle. As I drove home I reflected that repairing wind turbines isn't the sort of work I'd like to be involved in. The views must be great but the wind, the rain and not least the height and precariousness of your workplace are not to be envied.

Living the high-rise life

click photo to enlarge
On my recent trip to London I walked up the south bank of the Thames, past the MI5 building, to Vauxhall to see St George Wharf and, in particular, a new 50 storey residential tower that is approaching completion. This area has been developed with a complex of expensive and distinctive, river-side towers and blocks. The shiny new skyscraper that has grown up beside them seems to have settled on the generic and rather presumptuous name of The Tower.

Will such a name last? Can it when it is one among many towers? Is this a grab for a name that distinguishes it from all the other particular towers? Who knows? What I do know is that already the building has a certain fame and notoriety. On completion its 594 feet (181 metres) it will be the tallest residential tower in the UK, and this fact has caused some commentators to say it is too high for the area and too high for its relative proximity to the Palace of Westminster. Fame of a different type attached to the tower when, on 16th January 2013, a helicopter struck the construction crane attached to the building, causing the helicopter to crash into the road below, hitting two cars, killing the pilot and another person, and setting two buildings on fire. Such an occurrence is, thankfully, very uncommon, yet the fact that it has happened once must put the thought of it happening again into the minds of some high-rise residents, and will make people consider the down-side as well as the up-side (pun intended) of high-rise living.

The exterior of the new tower is, to my mind, fine without being particularly special. The broadly cylindrical shape is not unpleasant but doesn't offer an overall form or specific details that strongly distinguish it from others or that cause the viewer's gaze to linger. The blue glass looks attractive, as blue glass often does, yet one has to wonder how much longer it can survive as the default tint. The tower is topped by a disguised wind turbine to power some of its lighting and heat-pump technology will take warmth from the water of the London aquifer. These and other design features will mean it needs about one third of the energy that a typical tower of this size consumes, and its carbon dioxide emissions will be half to two thirds that of a similar structure.

I spent a few minutes watching the workmen as they went about the task of putting the finishing touches to the building. Two orange clad men made useful indicators of the scale of the structure. They were dangling on ropes and appeared to be washing the windows (surely not) or applying something to the glass or glazing frame. Incidentally, the smaller photo is a crop of a larger image.
