The concept was advanced as a means of developing natural gas reserves in remote offshore areas. Such a floating plant would convert natural gas into the liq- uid, methanol, at the production site for transshipment by tankers. In a joint announcement, the firms said they have been pro- ceeding since March 1976, with a study on a plant of 2,200-tons- per-day capacity. "This study, which is almost complete, con- firms that a floating plant is technically feasible and more eco- nomical than land-based construc- tion," they stated. Their research stemmed from earlier studies performed sepa- rately by Conoco and the Jap- anese group. Conoco's studies, initiated in 1972, sought devel- opment of methods to develop gas fields too remote or too small to justify pipeline installations to shore. Studies by the Japanese group in 1974, based on a 1,000- ton-per-day plant, "obtained sat- isfactory results as to its tech- nical and economic possibilities." The joint study covered deliv- ery systems to the plant, the question of converting a used tanker or building a new barge, detailed design of plant and ves- sel, transportation of methanol products, and potential methanol utilization. The group listed three key ad- vantages : where pipeline con- struction is uneconomic such a plant could be transferred from field to field; it could be built to exacting specifications in a ship- yard, avoiding potential delays and the difficulties and higher costs of building a facility in a remote offshore area; and it would obviate the need for large investments in harbors, roads and related shore facilities. Both Conoco and the Mitsui group are considering the possi- bility of making more definitive studies, especially of aspects not considered in detail in the study. True or False?
