Fig: Bilge plates covered with burlap and ready to load grain
It is customary to cover bilge well cover strainer plates with burlap and cement around the perimeter, or there may be a bolt down system. Some cargoes, such as zircon, andalusite, titanium slag or chrome ore are contaminated by cement or cement dust. In these cases, the burlap should be positioned using marine tape. Kraft paper can be considered for certain cargoes to prevent dust and silt.
