Sweep

Marine debris trash boom - The Ocean friendly trash remover

Combatting Marine Pollution with the Sweep – series will result in a much cleaner shoreline and reduce the plastic
in the water significantly. The concept is well proven within the Oil Spill Combat industry when recovering heavy
fractions of oil/tar balls.
Experience has shown that it is important to have puncture resistant guide booms creating the opening of the
system. DESMI is using two sizes: Ro-Boom 650 and Ro-Boom 1000 as guide booms. The guide boom 650 is 2
sections, each with 3 air chambers. The guide boom 1000 is 2 sections, each with 5 air chambers. The actual collection
part of the Sweep series consists of an entrance net connected to the two guide booms. The entrance net
is again connected to one or more trawl bags recovering the floating debris.

Advantages

The other end of the guide booms has tow bar and towing rope connected to one or two towing boats. If towing
with two boats, it is important to ensure good and constant communication between the boats. With one boat
operation there are two possibilities:

Having the boat equipped with a Jib with a length of typically 5 – 8 meters giving a corresponding opening
of the Sweep
Using a Ro-Kite which will allow an opening of up to 20 meters – will normally require a boat minimum 12 – 15
meters in length with keel and some 150 hp
