In phase I methanol plantship (MPS) work sponsored by the Department of Transportation in fiscal years 1985 and 1986, the contractor identified uncontested methane sufficient to operate 130 MPSs for 20 years, each being of 3,000-short tons per day (2,722-t/d) capacity; demonstrated by analyses and by ship model tank tests that long-term efficient methanol plant operations can be conducted in at-sea environments; and showed that the economics of MPS operations are competitive with land-based plants. Part I of phase II (FHWA-RD-92-085) assessed the impact of new permitting and environmental legislation on the design and operation of the MPS. The impact of new laws and regulations are measurable. Design and construction costs will increase when design changes are made in order to meet new allowable pollutant release rates; operating costs will increase in order to implement a program that meets new planning, monitoring, and reporting requirements. MPS operability, however, was found to be unaffected by new statutes and changed regulations. New parametric analyses concluded greatest economy of scale at 3,000 short tons per day (2,722 t/d). Research of the MPS design efforts of other similar projects discovered no basis for discontinuance or change of development efforts or plans. Part II of phase II confirmed that the MPS can address economically, without consequence to production rates, natural gases with impurity levels in excess of 25%; a useful methane supply, cost, and composition was confirmed at several sites of interest. MPS design changes to enhance operability and product quality were accomplished; the MPS specification and quotation assembly drawings were detailed to enable refined cost estimation of the MPS to -5% to +15% accuracy. Costs were determined for the preparation of an MPS "go to construction" bid package, for detailed design of the MPS, and for construction/installation of the MPS.
