They have been called “Vacuum cleaners of the sea” and are
aluminium catamarans built under Bureau Veritas supervision, using simple
patented techniques to collect oil without using any chemicals.
Operating Principle
On engine start-up, a water flow is created between the twin hulls and
floating waste is sucked in. This flow is separated into two layers, the
lower layer discharging clear water via the propeller in the stern.
The surface layer carrying floating waste and hydrocarbons is first passed
through a wire mesh basket to collect floating debris. The basket is emptied
into a storage container on deck. The hydrocarbons are captured by an
integrated oil interceptor and stored. The cleaned surface water is discharged
at the stern.
Hydrocarbons are drawn in by the turbine effect of the propeller, such
that the oil layer is sucked in whether the vessel is moving forwards,
astern, or is stationary. The vessels can work in confined spaces, between
boats in a marina, or moving along a dock wall, due to the rollers in
the four corners of its structure.
There is now a family of vessels, from the 6.6 metre long Cataglop L
for small ports and marinas, through Cataglop (7.5 metres) and the Cataglop
XL (9.2 metres, capable of 6 knots), all road trailer transportable.
The latest addition to the range is the Workglop range (10.6 to 12.8
metres), able to provide wind farm and offshore platform support as well
as pollution clean up, with its deck crane.
In addition there is the Spillglop family (18 - 24 metres) for major
offshore spills and able to work in conditions up to force 6. These can
tow floating flexible oil storage tanks to allow large amounts of oil
to be collected. The system is far more efficient than traditional boom/skimmer
methods and the vessels can also work in heavier sea states and at higher
speeds.
