Conclusion: The technology of enduring and sustainable marine 
structures indicates a modularized floating platform of large 
scale, constructed primarily of prestressed concrete elements 
and configured for hydrodynamic stability within a critical 
range of sea states. 
Observation: Structural engineering literature is rife with 
evidence of the suitability of reinforced concrete as a dur- 
able and economical construction material for the ocean envi- 
ronment. This has become particularly evident with the devel- 
oping technology of prestressed concrete. Eberhard Lemcke of 
Bechtel Civil Inc., in his report of design studies on the 
technical feasibility of floating structures suitable for 
aircraft operations and industrial uses, such as for warehous- 
ing or fishing industries, found prestressed concrete to be a 
superior alternative (Item 11, Appendix E). Lemcke's analysis 
of alternative steel and concrete decks supported on buoyant 
cylindrical concrete columns favored the concept of steel 
decks for load bearing, weight distribution and economical 
considerations. Bechtel was given the assignment to perform 
their study in August 1984 by Kumagai Gumi Co., Ltd. of Tokyo 
in anticipation of placing a single-point moored commercial 
airstrip in Tokyo Bay. 
Conclusion: Performance of modularized ocean basing systems 
can be demonstrated as significantly superior in terms of 
cumulative logistic throughput on a daily basis over that of 
present U.S. capabilities for projecting military force 
assuming a dearth of proximate foreign basing assets. 
Observation: In terms of daily useful availability of Cumula- 
tive Logistic Throughput, the superiority of MOBS over Basing 
System II (without MOBS) varies between 20% and 28% during the 
90-day ramping-up period. This is depicted in the Third-World
