Malakal Harbor visits Weymouth Harbour

Malakal Harbor is a floating work platform, typically used for repair tasks. Today, it was in Weymouth Harbour to dredge some concrente spillage from the recent Harbour wall repairs. Her marking is YD206, but we were not able to find her details anywhere in Lloyds Register, UK Marine Register or World Registers (over 500,000 vessels listed).

Assisting operations was a diver, attempting to identify and attach haulage straps to underwater obstacles. The operations took around 3 hours or so. We are not sure if these works will resume tomorrow. Among the debris were a large “slab” of hard concrete and some rebar, plus what appears to be discarded piping.

(Malakal Harbour is in Pilau, part of the Caroline Islands, Micronesia. We imagine the vessel reflects the name of this beauty spot in the Pacific).

Weymouth Harbour Wall Repairs – final stage

Anyone who read our previous blogs on the Weymouth Harbour wall repairs will assume the works finished on 23rd December last year. However, unforeseen problems in the pile driving phase caused delays. These prevented some overlapping tasks, which may now stretch until mid February. It is helpful to compare pile driving to archeology – one never really know what’s down there!

Infilling waling beam trench and gap-filling between the piles

We started writing these particular blogs because we feel repair and strengthening of areas of the Harbour are essential works. The aim is to maintain the beauty and functions of our working Harbour, for years to come. Knights Brown Construction and Dorset Council have been informing affected local businesses but sometimes have been overtaken by events. In any event, the contractors and local authority have been MUCH more informative and responsive than during the ill-fated repairs to the old Condor Ferries Berth 3 back in 2012/3.

Shuttering for the concrete capping (8th January)

At the time of writing (11th January), remaining works included the last capping beam concrete pour and replacing the Ferry Steps. Then there are – levelling, making good, reinstating safety railings, resurfacing and clearing the site. We hope to add a few photos in later updates to this post during these concluding works, as they arise. We may be able to add a short video clip of the finished result. Then we shall be back to blogs about visiting luxury superyachts, Naval vessels, Tall Ships and Harbourside events, such as the Seafood Festival.

Updates (after 11th January)

Update on 15th January: Yesterday’s storm (Brendan) slowed work on the site but more backfilling and welder-cutting for pipe egress was attempted. The wind was swaying the crane alarmingly and work had to be halted in the afternoon. (No pictures – far too wet and windy!)

31st January 2020 – The large crane (Old Squeaky) was dismantled (using another box-crane) and disappeared from site around 11:30 a.m. It transpires, the crane may not have been causing TV interference after all. At least we can now investigate other possible causes, having eliminated the most obvious suspect.

Storm Ciara caused quite a stir last weekend (8th/9th/10th February,. There were gusts of wind up to 60mph and lots of rain. Some site barriers toppled in places and crashed against Roundhouse walls. The worst of the weather was not filmed due to even worse wind and rain later, naturally. (Film clips courtesy of Roundhouse Hotel Weymouth).

Week ending 14th February

Removing barriers and re-opening the road to traffic – 14th February

There remain a few more finishing jobs and complete site clearance is not expected for another week. Safety railings will be added later (etc). However, the repairs are essentially complete and are looking quite tidy.

Christmas Day Swim – Weymouth Harbour 2019

Or – The great Walls of Weymouth

The Christmas Day Swim in Weymouth Harbour took place this year in brilliant sunshine. In fact, the sun was so bright, it made photography very difficult from the South side (finish line). We are indebted to Oakes Insure for some excellent photos from the starting jetty.

The air temperature for the Charity Swim was about 10 degC, also the water temperature (according to google – Alexa). There was very little breeze but the shock of hitting cold water exposed several swimmers to cramps, “brain-freeze” and some muscle injuries (including Mark – Wobbly Fish). There were 471 competitors in 9 heats and upwards of 20,000 spectators watched till the end. The Christmas Day Swim raised £1000’s for Charity (plus not a few goosebumps). (See our YouTube Channel for other videos).

There was due to be a fourth member of the Wall family undetaking the swim but an unfortunate “illness” overtook Karl the night before (early “brain freeze”). We are hoping to get Claire to have a go next year…..

Weymouth Harbour Wall repairs – Update at mid-stage

Without recapping all the data in the previous post, we would like to update further work on the Weymouth Harbour Wall repairs at the midway stage (last week of pile-driving?) During 19th November, the contractors swiftly moved the piling jig another 10 metres or so along the Harbour Wall repairs site to the final position (Western end, 74m).

Very quickly, the piling rig was then fitted with piling guides and another 6 piles were lowered into position. Ancillary work onvolved spot-welding and cutting where the “ears” of the “staples” were deformed and manually “knocking” the piles into alignment, against the wind and crane movements till they could slide smoothly into place. Below is a “sequence” (actually compiled from 2 adjacent pile emplacements).

You can easily see from the above why the Council and the Contractors advised us to close for the duration of the works! (See here for a contemporary update from Weymouth Harbour website). We are also being kept informed regularly by Dorset Council, in turn advised by Knights Brown Construction, the contractors. Also, note the dust and grime adhered to the outside of the windows. Together with extra internal dust generated by pile driving vibrations, this is another reason for closing our business during the works. Latterly, we have discovered TV interference effects.

Self-explanatory, really. Aligning the piles and hammer before “tapping” then into stable locations. Then the sustained piling begins. Expected to take a few days. Note how much construction dust and dirt has been accreted onto the outside of the windows!

Note the occasional transient excursion in vibration records below. In this example, the peak-to-peak transient was approximately + 50 to – 80 mGal, or about MMI 4 (possible damage). Peak-to-peak the gap was about 130 mGal – or MMI 5 (persons may lose balance, significant building damage) – BUT – it was only a transient, not continuous, not repeated many times and not resonant – so no observable damage likely.

A couple of small items were vibrated off shelves

Also note, our measurements are NOT accurate, NOT ground displacement figures and NOT directly relatable to MMI values. MMI itself is a scale more usually associated with earthquake events (running from 1 – no effects, to 12 – total destruction). We only use these results as rough indicators.

Transient excusrion captured 19th November, ca 5pm, around + 50 milliGal and – 80 milliGal

Pile driving vibrations and resulting damage to nearby structures is a long investigated subject and surprisingly complex (Some accessible texts are – http://onlinepubs.trb.org/Onlinepubs/hrr/1967/155/155-002.pdf https://www.diva-portal.org/smash/get/diva2:610771/FULLTEXT02.pdf https://en.wikipedia.org/wiki/Pile_driver )

Update: 22nd November

We shall not bore you with another series of vibration graphs – just some typical data as the crew near completion of the piling stage (about 12 metres distant).

About +40 and -30 mGals.
Note the sound spectrum is very wide, reflections and reverberations spreading the spectrum

As with the vibration graphs, the sound level graphs are NOT accurate and depend significantly on factors such as microphone quality, sampling rate and software rendering. As a very rough guideline, the sound and vibrations are disturbingly loud indoors and sufficient to dislodge some items from shelves, rattle toilet seats, windows, doors, floorboards and plumbing against fixings. However, we see no significant damage yet.

Weymouth Harbour wall repairs

Brief notes at 6-week stage (16th November 2019)

After 6 weeks and despite many signs stating the road is closed, we still get up to 1000’s of pedestrians and drivers who refuse to believe the road is actually closed!

Initial survey

Before commencing the Harbour Wall repairs, it was necessary to establish the existing condition – of the wall and nearbyconstructions and busines premises. There was a preliminary survey in several phases. This was carried out prior to work commencing (30th September) with a main aim of checking external condition of nearby buildings. This would enable any damage caused by pile-driving and related operations to be determined

There was then an internal survey using old-fashioned methods (camera and clipboard). (peter.christie@dorsetcouncil.gov.uk).

Demolishimg the old kiosk building @ Ferry Steps

The next phase of Harbour Wall repairs was to demolish the old storage and sales kiosk, built above the waling beam next to the Ferry Steps. Initially, the building was shrouded in temporary sheeting, checking for and removing any potentially hazardous materials. Then the “JCB” moved in a flattened the site in short order.

Further work includes replacing parts of the existing waling beam (anchoring structure for the tie-rods holding existing and new sheet piles in place – the tie rods are alleged to extend some 23 metres underneath the adjacent buildings).

Pile Driving operations

The main work involved pile-driving new sheet piles about 0.5m from the existing wall surface profile, about 18m into the subsoil. Originally, it was suggested a 4.5 Tonne hammer would be used to start the piles into position, followed by a more substantial (45 tonne?) ship-mounted hammer to drive the piles fully home. We have no specific information (as public) but we think the current hammer is a half-tonne hydraulic type – the noise is quite substantial and vibrations presently lie around 20 – 50 milliGals.

The piles will be cut as needed for drainage and tie-rod fixings. The gap will be back-filled with reinforced concrete, with ancillary works to fix in new sections of waling beam. The whole project is being (part?) funded from a £1.9 million Coastal Regeneration Scheme opening the way for the Harbourside Redevelopment Scheme(ca £3.3million?). When the repairs are completed, there are plans for new Harbourmaster and fishing buildings plus a scenic walkway around the Peninsula perimeter. Any flood defences would be funded from a different scheme.

Vibrations

Discussions of vibrations arising from pile driving and consequent effects on nearby structures tend to get a bit complex. In very general terms, ground displacements of 2mm/sec or more poses some risk of minor damage to older buildings (such as Listed Grade 2 Aaran House), while displacements above about 5mm/sec may cause significant damage. Hammer weights about 0.5 Tonne and frequencies about 1/sec tend to fall into the range of MMI (Modified Mercalli Index) 3 (noticeable but very little damage) while “heavier” impacts and higher frequencies can push perceived effects up to MMI 4 (minor damage) or even MMI 5 (significant damage, difficulty maintaining balance). The Council advised us to close for the duration and we took their advice.

Above, we see a few graphs of accelerometer readings vs time, during the early weeks of pile driving. Note the acceleraometer was not too accurate or sensitive and the sampling rate was low – which may cause some peaks to be “missed”. Using the archaic non-SI unit, the Gal, we can see background levels around 2 milliGal, rising to around 50 milliGal, as the operations got nearer. There is no easy relationship between Gals and mm/sec ground displacements but the MMI scale would suggest 30 to 50 milliGal = MMI 3, roughly. We have observed only slight plaster cracking and a little dust fall.

Closure of Esplanade to Custom House Quay road and pavement junction

Meantime, up to 2,000 pedestrians per day and 100’s of motorists are “visiting” the site, at least as far as the road closure next to The Roundhouse b&b. It is quite amusing to see all those stern faces crumple into astonishment when they find out a half-dozen “road closed” and “diversion” signs were not just dumped for fun and the road into Custom House Quay really is closed (6 weeks till now: another 6 weeks to go approximately).

The Council (DCC, formerly WPBC) have advised the nearest properties to close during the period of works, for safety, noise and disruption reasons. Hence, we are closed (since 1st October) till the Christmas period (scheduled completion 23rd December). We are hoping for compensation due to business interruption.

Reopening in 2020 – early in January

We apologise for any inconvenience to guests who would have wished to book our guesthouse this autumn, but the works were essential and closure was unavoidable. It was only a few years ago a section next to Condor Ferry Berth collapsed. Allegedly that was in relatively sound condition compared to the current repair section. Of course, public safety is paramount and works have continued as rapidly as feasible. We thank all our guests for visiting us in the past and we hope to see you all again next year. Happy Holidays!

Raft Race across Weymouth Harbour – 31st August 2019

Raft Race on 31st August 2019 – Weymouth Harbour

We were alerted to an event going on behind Aaran Guesthouse on 31st August by the booming voice of Steve Davies, Weymouth’s noted commentator. We emerged to find a raft race, between crews, mainly in fancy dress, proceeding from the Ferry Steps behind us to the steps on the opposite bank. There were about 8 crews: For us, the Vikings stood out, with sneaky tactics of squirting bale-out water over rival crews as they paddled nearby.

On the far bank was a welcoming committee, including a small dinosaur. About 100 people watched the event, which had all the flavour of a typical Weymouth activity – eccentric, fun and something always happening. We searched afterward for news online but could find none. We imagine the race may have been connected with RNLI Charity events concurrent in Bridport/West Bay and Poole. Anyway, it was a fun and interesting diversion from cleaning the kitchen (again!)

(Footnote: currently, October to December 2019, the Harbour Wall up to 20m either side of the Ferry Steps is being repaired)

Weymouth RNLI Celebrates 150 years of Lifeboats

28th July 2019

Weymouth Lifeboat Station was opended 150 years ago and this year, the event was celebrated with a flotilla of lifeboats through the ages. This took place right behind Aaran Guesthouse, in Weymouth Harbour, so we were well placed to view the parade of boats. Yet another Weymouth Harbour event.

(See our YouTube Channel for more videos)

Spy Drone over Weymouth Harbour – 16th/17th July 2019

Survey Drone overflies the Devonshire Buildings in Weymouth

Some people imagined it was Amazon delivering a “cloak of invisibility”. A few thought Putin was spying on us, or Facebook, or Google or any number of possibilities. In fact, it was a survey drone sent to image the buildings. The inspectors were looking at facias and roof structures for possible existing damage. Alternatively, they could assess risk of damage which might occur during Harbour Wall repairs later this year.

As “spy drones” go, this was a somewhat noisy affair. One could imagine Taliban fighters (etc) spotting the machine and shooting it out of skies within a few seconds of deployment. Onlookers noted a level of “dissatisfaction” among the populations of rooftop gulls, rooks and crows, during its flight pattern. We do not know whether militarised spy drones are quieter, but we hope so. It was difficult to determine the drone manufacturer nor make of camera carried, but the latter appeared similar to Canon-style video devices in common use. Flight times were about an hour each, in several sessions. Today, 17th, the Pavilion Theatre is under survey. This was a distinctly unusual instance of “sights in Weymouth Harbour“.

As for the Harbour Wall repairs, these start 30th September and last for several weeks, until early December. Preparatory works will lead onto reverberatory pile driving, followed by percussive piledriving, finishing and making good works. It is expected most of the nearby guesthouses, including ourselves, will close during these works, for reasons of noise, access and safety. We hope our respective guests will bear with us and come back afterwards, to enjoy our hospitality, perhaps in the Christmas Season or New Year.

Nyetimber Seafood Festival – Weymouth 13th, 14th July 2019

This year’s Weymouth Seafood Festival was sponsored by Nyetimber, makers of fine English wines. For many years, Pommery led the event and it is exciting to see a new sponsor organise this great event.

We popped out and took a few images (gallery above) around Aaran Guesthouse, on the Northern side of the Harbour. Some of our guests wandered as far as Hope Square and reported live music bands and many more stalls along the Cove Row side of the Harbour. Over 40 food specialists displayed their wares, from the Pavilion Theatre forecourt, down the harbourside to the Town Bridge and back along Cove Row towards Hope Square. Numerous other stalls could be seen, dotted among the main displays and in a few of the Guesthouse rear yards (e.g. The Gloucester at The Lantana). Not forgetting, numerous permanent Pubs and Restaurants, serving great seafood all year round (e.g. Ship, George, Enfants Terrible)

The weather over the weekend was warm, with sunny spells and a light breeze – much appreciated while sitting enjoying the food and the scenery outside the Harbourside pubs. Tens of thousands of visitors crowded the Harbour, looking for the ideal meal among the many options. We spotted crispy squid, “experimental” marmalades (eg. carrot, parsnip, etc), crepes, specialist gin, oysters, Thai Cuisine, Paella, Chimonea-fired pizza, Organic Farm produce, local cheeses, produce from The Garlic Farm, Isle of Wight, as well as some “usual suspects” – Weird Fish, CEFAS (Centre for Environment, Fisheries and Aquaculture Science) and no less than THREE cooking stages, with famous chefs showing their skills and tips for the public. A great day for exploring with this afternoon (Sunday) still to go…
