General
Originally the vessel was built in 1982 by the East-German VEB Schiffswerft
Neptun as a navy supply vessel. In 1998 the vessel was lengthened and converted
into a general cargo vessel.
In 2002 the vessel was purchased by the Dutch company Schotsman B.V. at
Terneuzen and converted to an aggregate dredger by Shipyard Boer, named
'Schotsman'.
The dredging equipment installed consists of a single trailing suction pipe
arrangement at starboard side at main deck level, a static sieve mounted on
the fore deck connected to a closed launder with four hydraulically operated
doors to load the hopper during trailing and two barge loading pipes mounted
on main deck level at port side.
The vessel is equipped with four hydraulically operated bottom doors and a
drainage system for de-watering the load of sand in case of unloading by
shore based grab cranes.
