25
Tonne Raft, Loch Etive, Scotland
Measuring 12m x 14m this raft
has 140 square metres of hanging space and is capable of holding
400 mussel droppers and a wet weight of mussels of 25 to 30
tonnes.
This raft is made from the best materials for a long maintenance
free working life. Two buoyancy pontoons support the hanging
rafters and provide a safe non-slip loading and work area. Other
design features include an unsinkable buoyancy system, heavy
duty mooring points and attachments, easy transportation and
assembly. All steel components are hot dip galvanised to BS729
and each raft is supplied with a recovery ladder and life ring.
The raft can easily be fitted with predator nets to prevent
bird predation.
Material Specification
All steel to European Standard EN 10025 S275. All joists hot
rolled to BS4360. Galvanising to BS729 or DIN 50976 minimum
size coating of 110 microns. All fixing bolts hot dip galvanised
M88 high tensile. Flotation unit cases are rotationally moulded
in PE with a minimum wall thickness of 6mm and subsequently
filled with a closed cell polyurethane foam. |

35
Tonne Raft, Loch Etive, Scotland
Measuring 14m x 14.5m this raft
has 160 square metres of hanging space and can hold up to 22
hanging rafters. A maximum carrying capacity of 35 to 40 tonnes
is recommended. The buoyancy supplied with the raft is usually
tailored to customer requirements. As with the 25 tonne raft,
this model is constructed from the best quality materials and
utilises the longest currently available steel beams to maximise
the usage of space and minimise the cost. This raft has three
buoyancy pontoons supporting the steel joists and is assembled
on site using high tensile galvanised nuts and bolts. The raft
provides a safe and stable work platform which can withstand
conditions in semi-sheltered sites experiencing wave heights
of 1.8 metres SWH, above this and stock loss may become a problem.
Other design features include; unsinkable closed cell PU filled
buoyancy units, six heavy duty mooring points, emergency recovery
ladder and life ring, easy transportation and assembly. The
raft can easily be fitted with predator nets to prevent bird
predation.
Material Specification

Mussel
Lines , Scotland
On some sites, long lines may be
more suitable than rafts. If predation by ducks is not an issue
then the long line system is very cost efficient but may require
larger more sophisticated items of equipment to handle the stock.
Our long line float system has been tried and tested over many
years. We offer two different sizes of float, 300 litre or 400
litre. Both are made from UV resistant polymers, are dark grey
or black in colour to minimise visual impact and can carry two
leadlines. |
