Monster Crane Passes Along Sussex Coast

When having returned home last night (Mon, Aug 12 2019) just after 8-30 as dusk was closing-in, I noticed a lot of lights out towards the far horizon and a red light – ‘Oh, a distress flare’ I thought for just a moment but no, it was a flashing navigation light atop the world’s third largest floating crane.  It’s absolutely Gigantic!  It is currently on passage being towed to the the Bahamas for the Gulf of Mexico at just 6.5 knots.

Statistics.

The Saipem 7000 has two NOV Lifting and Handling AmClyde model Saipem 7000 fully revolving cranes. Each has a 140-metre-long boom fitted with 4 hooks. Each crane is capable of lifting up to 7,000 tonnes at 40 m lift radius using the main hook. The auxiliary hook capacities are 1st Auxiliary 2,500 tonnes at 75 m radius and 2nd Auxiliary 900 tonnes at 115 m. The whip hook has a capacity of 120 tonnes at 150 m. The 2nd Auxiliary hook can be deployed to a water depth of 450 m. The two cranes are capable of a tandem lift of 14,000 tonnes.  (Taken from Wikipedia).

Each crane was fitted with 15,600 hp (11,630 kW) engines to power the boom and load hoists, 9 tugger lines and the crane slewing system. The cranes use 48 miles (77 km) of wire rope of various diameters.

Ballast system.

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.

Power system.

The vessel’s main power is provided by eight 12-cylinder 8400 hp diesel engines built by Grandi Motori Trieste, a former Fincantieri company. Later Grandi Motori was purchased by the Finnish Wärtsilä. They provide up to 47,000 kW of electric power at 10,000 V 60 Hz for propulsion and positioning. Auxiliary power is provided by two 6-cylinder 4,200 hp (3,130 kW) GMT diesel engines. There is also an emergency generator.  Total power that can be supplied is 57,000 kilowatts (76,000 hp).

Working off coast of Norway.

Thursday, July 25th – A Storm Arrives

The weather suddenly turned quite dramatically here early this evening, this happening on the hottest day of the year – indeed at Cambridge, it breaking the all time UK record for the hottest day, it reaching 38.7C (101F) and here reaching about 32/33 degrees C…
Late-afternoon, and the sky had gradually changed from broken cloud to menacing dark-coloured clouds, this change approaching from the SSW.  At 5-55pm, a few heavy spots of rain began to fall, thunder and lightning seen and heard about 4-8 miles away out to sea to the SE, the eye of the storm about to miss the Hastings area and probably making landfall towards the Rye area to the east.  By now, fairly torrential rain was falling, the street gutters now swollen.  But the South wind!  Firstly, a large area of sea perhaps 2-3 miles out to the SE took on a whitish, almost misty appearance – it being whipped-up by the wind.  The sea generally at about the same time, went from a deep blue, a little choppy with some ‘white horses’ to within 10 to 15 minutes, a wild, winter seascape – the sea becoming completely quite rough and dichromatic with the countless crests of white-topped waves!  I have been lucky through life to have witnessed the sea in many of its moods but I have never witnessed such a dramatic change, within such a short period of time!
By 6-15pm the situation had peaked, the storm having passed by and over the following 10 minutes the wind abated, the sea quickly calming again and becoming a settled blue again by about 6-25pm.

Tuesday’s Dramatic Sky Observations

Tuesday, June 18, and from my fairly high bay-window vantage point, a number of notable weather and astronomical observations were in evidence…

The day started off greyish, quickly brightening up through the morning.  From late-morning until late into the afternoon it was very humid.  During this same period, far out towards the seaward horizon, lay a thick band of brown, polluted air that was quite distinct with the unaided eye, probably arising from the dirty fuel that most ships still use.

Late-afternoon and the sky clouded over.  (Mid-evening and the cruise ship Queen Elizabeth 2 sailed down Channel making for St.Peters Port).  Late evening, and very low over the far south-eastern horizon the full moon – minus a day, slowly rose from out the blackness – it probably being the most blood-orange-coloured moon I have ever witnessed in my entire life!  Fantastic!

As it slowly rose in the heavens, it was consumed by the storm clouds of a fierce  electric storm which radar showed to have developed over the mid-Channel on air coming out of the Cherbourg peninsula, this drifting north-eastwards and clipping Sussex and Kent, there being much intense fork lightning, thunder, a stiffening breeze accompanying the intense rain that arrived just after 11pm, the roads resembling rivers.  The storm then slipping away some 40 minutes later.  What a spectacle!

Cruise Ship Britannia

7-50am, and the Britannia is steaming past Britannia – well to precise at this moment, St.Leonards and is relatively speaking, close in at 13 miles and on passage from Bergen in Norway and making for Southampton for an 11am docking.  She is easily identified by her twin funnels.

The MV Britannia is a cruise ship of the P&O Cruises fleet.  She was built by Fincantieri at its shipyard in Monfalcone, Italy.  At 143,000 GT, Britannia is the largest of seven ships currently in service with P&O Cruises and she is also the flagship of the fleet.  She officially entered service on 14 March 2015, and was named by Queen Elizabeth II.  Britannia features a 94 metres (308 ft) Union Flag on her bow, the largest of its kind in the world.  A beautiful looking ship but cruising wouldn’t be my choice – all that frivolous consumption would be at odds with my environmental beliefs!

Length: 330 m   Capacity: 3,647 passengers         Cost: £473 million            Speed: 21.9 knots (40.6 km/h; 25.2 mph) @ 136 rev/min.

Salt Marshes – Our Unsung Landscapes

Salt marshes are the unsung heroes saving our coastlines

Paul Simons, The Guardian, Tue 19 Feb 2019.

Salt marsh in Norfolk.

Salt marshes are not glamorous – muddy flats on coasts and estuaries, washed with seawater on the tides, where only specially adapted plants can survive in such a tough salty environment.  Although frequently ignored, salt marshes are unsung heroes. They help protect coastlines from storms, storm surges and erosion by creating a buffer between dry land and the sea, building up the height of the coast by trapping silt during floods and adding new soil from their decaying vegetation.

Less well known is that salt marshes lock away vast amounts of carbon by taking carbon dioxide out of the atmosphere through their plant leaves and storing it in the roots. And, when the plants die, the carbon becomes part of the soil. Salt marshes also provide a refuge for birds, fish and invertebrates; they provide clean water by filtering runoff, and they are low maintenance because they naturally self-repair.

But, in many places, salt marshes have been destroyed by drainage for land reclamation, coastal developments, sea walls, pollution and erosion. Globally, about 50% of salt marshes have been degraded and the rest remain under threat.

Schemes to restore salt marshes have proved successful, though, such as the Wallasea Island project in Essex, the largest scheme of its kind in Europe. Land that had been reclaimed for agriculture long ago has been turned back into wetland.

November Sightings

Tuesday, November 7In the morning, one of the largest container ships in the world passed down Channel off the Sussex coast.  She was enroute to Southampton on her outbound voyage from Europe after sailing from China via Sri Lanka while on her first round voyage.  The Milan Maersk is one of the largest vessels of her type in the world with a capacity for 20,568 containers – that’s nearly 400 containers more than the previous largest.  In 2016 the largest container vessel calling in Southampton had a capacity for 16,000 containers.

The megaship belongs to the second generation of Maersk Line’s Triple-E class (Economy of scale, Energy efficient and Environmentally improved) and is part of a series of eleven container ships, which will be delivered by the end of 2018.  Milan Maersk’s propulsion and software system creates energy savings which aims to reduce carbon emissions per container vessel by 35 percent.  This new generation of more efficient and environmentally friendly container ship joins LNG (Liquified Natural Gas) and solar powered RoRo vessels already visiting the port of Southampton.  For more technical information see    https://en.wikipedia.org/wiki/Maersk_Triple_E-class_container_ship  ).

Thursday, November 9.  With thick grey cloud overhead at daybreak, there was a clear, fabulously-coloured sky out at sea towards the south-east, creating brilliant blue skies with a golden sun surrounded by bright vermilion skies, casting bronze hues on the autumn-tinted trees near my house.

 

October Sightings

Saturday, Oct 7th.  During a grey, damp morning, I saw two groups of brent geese numbering perhaps 150 birds passing Hastings, battling head-on into the the strong westerly wind and presumably on passage from perhaps Siberia to spend the winter at somewhere like Langstone Harbour further along the coast.

Sunday, Oct 15th.  We went walking up on to Seaford Head and in the vicinity of ‘Puck’ Church’ were rewarded for in excess of 10 minutes by a peregrine jousting with a raven above the cliffs.  A sheer speed that the peregrine came in at for some of its attacks!

Monday, Oct 16th.  Very mild today!  Late afternoon today, daylight became quite weak and semi-darkness descended to be followed at dusk by a strange light – a kind of dirty orange light in the SW sky.  All due to the passing of tropical Storm Ophelia (producing near hurricane force winds) over Ireland, it also carrying north much dust from the Sahara and smoke particles from wild fires in northern Portugal.

Saturday, Oct 21st.  A gale (Storm Briane) and a spring tide produced some huge waves along the beach at Seaford, with the strandline out in the road in places.  Newhaven breakwater also took a pounding as can be seen in the following Facebook pic by Fergus Kennedy.

Tuesday, Oct 31.  Two large (each some 1,200 gross tons) Dutch-based(?) but British flagged trawlers, have been working some 10 miles off the coast from Hastings all day.  Not what the Hastings beach-based fleet wants to see?

Offshore Wind Power Cheaper Than New Nuclear

Status

Great news!  I see the Rampion Field offshore from Brighton is progressing – from Brighton Clock Tower looking down West Street, a rig and towers visible on horizon and full extent surprised me recently as it came into view whilst driving along A259 from Eastbourne.

Offshore wind power cheaper than new nuclear.  [ABRIDGED]

Energy from offshore wind in the UK will be cheaper than electricity from new nuclear power for the first time.  The development, revealed in figures from the government, has been seen as a milestone in the advance of renewable energy.

The plummeting cost of offshore wind energy has caught even its most optimistic supporters by surprise.  Nuclear firms said the UK still needed a mix of low-carbon energy, especially for when wind power was not possible.  The figures, from the Department for Business, Energy and Industrial Strategy, for offshore wind were revealed as the result of an auction for subsidies, in which the lowest bidder wins.

Two firms said they were willing to build offshore wind farms for a subsidy of £57.50 per megawatt hour. That compares with new nuclear plants at a subsidy of £92.50 per megawatt hour for 2022-23.

Emma Pinchbeck from the wind energy trade body Renewable UK told the BBC: “These figures are truly astonishing.  “We still think nuclear can be part of the mix – but our industry has shown how to drive costs down, and now they need to do the same.”

‘Energy revolution.’

Onshore wind power and solar energy are already both cost-competitive with gas in some places in the UK.  And the price of energy from offshore wind has now halved in less than five years.

Energy analysts said UK government policy helped to lower the costs by nurturing the fledgling industry, then incentivising it to expand – and then demanding firms should bid in auction for their subsidies.

Michael Grubb, professor of energy policy at University College London, called the cost reduction “a huge step forward in the energy revolution”.  “It shows that Britain’s biggest renewable resource – and least politically problematic – is available at reasonable cost.  It’ll be like the North Sea oil and gas industry: it started off expensive, then as the industry expanded, costs fell. We can expect offshore wind costs to fall more, too,” he said.

The subsidies, paid from a levy on consumer bills, will run for 15 years – unlike nuclear subsidies which run for 35 years.  This adds to the cost advantage offshore wind has now established over new nuclear.  Caroline Lucas, co-leader of the Green Party, said: “This massive price drop for offshore wind is a huge boost for the renewables industry and should be the nail in the coffin for new nuclear.  “The government’s undying commitment to new nuclear risks locking us into sky high prices for years to come. Put simply, this news should be the death knell for Hinkley C nuclear station.”

Nuclear ‘still needed.’

However, the nuclear industry said that because wind power is intermittent, nuclear energy would still be needed.  Tom Greatrex, chief executive of the Nuclear Industry Association, said: “It doesn’t matter how low the price of offshore wind is. On last year’s figures it only produced electricity for 36% of the time.”

EDF, which is building the Hinkley Point C nuclear plant, said the UK still needed a “diverse, well-balanced” mix of low-carbon energy.  “New nuclear remains competitive for consumers who face extra costs in providing back-up power when the wind doesn’t blow or the sun doesn’t shine,” the French firm said.  “There are also costs of dealing with excess electricity when there is too much wind or sun.”

Construction of the Hinkley Point plant is under way after gaining government approval last year.  EDF added that energy from new nuclear plants would become cheaper as the market matures, as has happened with offshore wind.  Eyes will be raised at this suggestion, as nuclear power has already received subsidies since the 1950s but storage of surplus energy from offshore wind is still a challenge.

Prof Grubb estimated the new offshore wind farms would supply about 2% of UK electricity demand, with a net cost to consumers of under £5 per year.

Experts warn that in order to meet the UK’s long term climate goals, additional sources of low-carbon energy will still be needed.

September Sightings

Saturday, Sept 9.  I took a railway excursion, ending up back on the coast at Folkestone. Rail travel I believe, is a fine way of seeing cross-sections of our landscape. On the outward journey north, I saw what were presumably, two hot-spots of ash die-back disease – one just north of Battle and a very noticeable area at and around Wadhurst station.  Added to this from time to time were instances of alder alongside watercourses, dead from Phytophthora.  Upon reaching Tonbridge station, I was greeted on Platform 3 by a large black and white cat sprawled across the platform grooming itself and not caring a jot about the comings and goings of people and trains.  By its persona, I can only assume it owns the station and answers to the name Sapphie!

See  http://www.kentonline.co.uk/tonbridge/news/station-cat-stars-in-railway-38942/

Folkestone harbour, has changed a lot from when I visited it once about 20 years ago.  A lot of money is being spent on transforming the redundant harbour into a public space with restaurants and bars and a pleasant walk along the long breakwater.  100 years on from WW1, I couldn’t help but think from time to time about the many troops that must have passed by the same scenes that I was seeing today.  The little shops and cafes down The Old High Street were enjoyable too.  A nice spot for a few hours ramble.  Continuing the theme of trees, I saw the two healthiest horse chestnuts for years, perhaps rather out on a limb and with the prevailing wind having a long fetch over the sea, they are protected from attack.

                                                                                                                                            I noticed that on the south-facing slopes of the North Downs overlooking the town that much of the chalk grassland was being engulfed by scrub.  What a pity…

Sunday, Sept 18.  Walked to Bishopstone Tidemills where there is much evidence of the archaeological digging being carried out unearthing the remains of the now ‘lost’ village.  I found the evidence of William Catt’s huge greenhouse intriguing with what I assume are heating pipes?

Monday, Sept 19.  Beautiful sunny day again.  Sat on the near deserted beach and watched lagoons formed by a low shingle ridge, flood on the high tide, these being patrolled by turnstones looking for food – especially washed-up mussels.  There have been numbers of large white and Vanessa butterflies along the beach of late, blown by the NE breeze or, are they possibly looking to migrate south??
