1 S-type dipperdredger "PUSHING DAISIES with BA 900 excavator 1

2 Pushing Daisies, an S-type Donge Dipperbarge dredger with BA 900: - A large dipperbarge with high breakout capacity up to 24 m. - An unique Backacter 900 installed, especially designed for dredging purposes. - Machinery space located inside the hull of the dredge. - Can work in sea-states till max. 2.5 metres. - The ideal tool for heavy, accurate dredging jobs. - Equipped with spares and self-contained for maintenance and repairs at remote sites. - "Deep Sea" hull and a bow being adapted to deep sea towing, on own keel, world-wide. - Large deck surface. - Self manoeuvrable with 2 x 500 kw HRP thrusters. - Home base: Singapore. Dredge characteristics Dimensions : x x 4.00m. Classification : Bureau Veritas: Dipperdredger Deep Sea, assisted propulsion Spuds : - 3 stabilising spuds: 1400 x 1400 mm. - basic length approx. 32 m. - weight about 65 tons each - fixed spuds. Miscellaneous - 2 x HRP thrusters, 2 x 500 kw. - the latest dredging instrumentation, with an accuracy of 5-10 cm. The bucket. The De Donge buckets with its Eurdo teeth, made of a.o. manganese, are generally recognised for the fact that the teeth hardly wear. Special pick points for rock dredging are available. Due to the high power up to 100 tons, the bucket is normally full. The capacity of the BA 900 combined with its high discharge height is the reason that big splitbarges can be used for this productive dredger. Dredging rock in Santos, Brasil 2

4 Pushing Daisies with its BA900 is regarded as one of worlds most modern dipperdredgers. All winches are placed underdeck in spacious winchrooms, each winch has 65 tons tractive capacity (4x reefed) and double brake capacity. A view on the 100% closed upperstructure of the BA 900, which prevents any entry of seawater, as well as preventing oil to leak in the water. The main engine and hydraulics are watercooled which produces low oil temperatures. This contrary classic (land) excavators which have open uppercarriages. Engine Room (under construction) all machinery is installed in a spacious environment. Machinery checks and maintenance can be done during excavation; which is obviously better compared to conventional excavators, which have the powertrain in the open uppercarriage. 4
