Ship Recycling Project Management Cornwall UK

Ship Recycling Project Management - Intro


The Wayfarer was a motor fishing vessel which operated out of Newlyn Harbour that was built in 1959 approx. Sadly she has fell in to disrepair and Southwest Environmental Limited were commissioned as project managers for the environmentally compliant removal of the Wayfarer from Newlyn Harbour.

The actual removal of the vessel started after an incredible 18 months work of paper work most of which was generated as a requirement of an environmentally (legally) compliant removal. It is important to point out that although it would have been easier to break up the boat with an excavator, or sink her to create a reef, neither would have been legal.



Having previously managed the removal of the The Children's Friend, we made a start on what was going to be a challenging project.

Ship Recycling Project Management - Process


The site team headed up by an experienced shipwright started work on the boat in situe, she was leaning heavily against the quay, and we needed to move the boat up to the landward end of the pier. In order to achieve this the the boat was lightened as far as practical with the winch gear being removed, and a good portion of the wheel house.

As we found her.
Removal of the heavier items.
After the heavier deck items had been removed we prepared to move up the boat to the land ward end of the quay. The boat was re-floated and pulled along to her final resting place. Having been neglected for close to a decade the boat had lots of leaks and the re floating took a number of tides before success was achieved.

Waste segregation took place on the qaut side, and as you would expect from a company call Southwest Environmental, the Environmental Compliance Side of of the project was given much attention. This included the generation of significant quantities of  paper work relating to duty of care.

Finally after weeks of preparation, stripping out internal structures, engines etc. the hull was ready to be cut in to sections.

Nearly Ready to cut in to Sections
The stern is cut free.
Once 1 or 2 section had been cut from the hull, arrangements were made to lift the sections from the harbour. At this point we could only guess at how much the sections would weigh, as they are very odd shapes it is hard to tell, and we did have a bit of a surprise when we found that some weighed 20 tons.

Her final voyage!
This boat unlike the Children's Friend  is not destined for landfill. The sections will be transported to Exeter Fabrications for compliant treatment and conversion in to ornamental structures. Give them a ring and buy a piece of maritime history.

Traffic Impact Assessment - Essex

Traffic Impact Assessment - Grays, Essex

A waste recycling firm are applying for planning permission for a change of use. The change of use triggers the requrement for a traffic impact assessment.

First off the baseline conditions must be considered which involves a through traffic count on the surrounding road network.

Traffic Impact - Lots of Data

This data is then used to calculate likely percentage increases from the development.

The Traffic Impact assessment includes commentary on the modal split of traffic in the area and the trip generation associated with the proposed development.


Traffic Impact Assessment - Most counts are now automated.

When considering the different modes of transport it is important to consider that  a small number of HGVs are likely to represent a higher percentage increase, as opposed to a small number of cars the affect of which is diluted within the often high numbers of trips that are generated by cars on most roads on a day to day basis.

Odour Impact Assessment & Odour Management Plan - Tiverton

Odour Impact Assessment  & Odour Management Plan - Tiverton



SWEL were engaged to provide supporting planning documents for a broiler breeder chicken shed near Tiverton, Devon. An odour impact assessment uses an atmospheric model to gauge the diffusion of an odour plume, plotting modelled odour concentrations on a grid, this grid is then used to create contours.

An odour impact assessment was required to assess odour impacts from the proposed shed which was to house 36,000 chickens. This may seem a large number but by today's standards this s a relatively small shed, sheds of 300,000 chickens are not uncommon.


Typically it is necessary to statistically manipulate results and give a US 95 or US 99 value for odour concentration derived balancing of model out puts and wind direction etc. but in this instance it was not necessary, worst case scenarios were modelled and found to be within accepted limits.

An odour management plan was also produced,  this is an operational document and is to be used by the site operator during the operational phase of the broiler breeder sheds. Odour control in large scale chicken sheds involves controlling  diet, watering and ventilation rates amongst other things.

Flood Risk Assessment - Exmouth

Flood Risk Assessment - Exmouth


If you find out that your site is in Flood Zone 3a this does not mean that you will not be able to build on / develop the site. There will be more paper work, and you may have to wait some time for the Environment agency to decide whether your site is in fact suitable, but in 90% of cases Zone 3a will not pose as an insurmountable barrier.


Such was the case with a site in Exmouth, near Exeter, Devon where an infill building plot, was partially within flood zone 3a. It was quickly established that a variance in ground elevation was the cause of this  incursion, and that likely ground raising associated with the proposed develop would effectively place the proposed dwelling above flood water levels.

Sunlight & Daylight Assessment - Hackney (N1)

Sunlight & Daylight Assessment - Hackney


SWEl have just sucessfull completed a sunlight & daylight assessment for an unusual retrofit project in Cazenove (Hackney) London.


The project invloves the install of a further two stories on top of an existing building the design is modern and well considered to reduce daylighting impacts, with a tiered design with width decreasing upwards.



The surrounding buildings were subject to considerable overshadowing prior to the development, and as such only minimal reductions in enjoyed light were acceptable.

Sunlight & Daylight reduction post project were within limits set in the relavent guidance, and as such the project with minor alterations was recommended to proceed.
