have been synthesized into a set of proposed design criteria and re- 
quirements for construction and installation of a DWF suitable for off- 
loading containerized and roll-on roll-off (RO/RO) cargo from a modern 
cargo ship. Where requirements are known they have been specified. 
These specified requirements are intended to be used as guidance and may 
be changed as more information on the proposed system is gathered. Where 
requirements are either not known or are uncertain a discussion of the 
uncertainty is included. 
1.4 Methodology 
The DWF concept will allow construction in a modular or building 
block approach. Many simplifying assumptions have been made to allow 
this modularity and to permit simple adaptation of the modules to a 
specific site. The assumptions have been made on the side of conserva- 
tism. Exceptions to this are noted in the text. 
1.5 Installation Sequence 
The DWF scenario begins with Figure 1, loading of equipment aboard 
the barges. Figure 2 depicts the transfer of the barges to the heavy 
lift ship. In Figure 3, the heavy lift ship has been ballasted down and 
the barges are being loaded aboard. Figure 4 shows the heavy lift ship 
fully loaded with 3 barges and their equipment, ready for transport. 
Upon reaching the forward site the ship is ballasted down and the barges 
floated off, see Figure 5. Construction of the facility may proceed 
either parallel to the beach as in Figure 6 or perpendicular to the 
beach as in Figure 7.
