Permea Maritime Protection Wins Order For World's Largest Membrane Nitrogen System A Norwegian manufacturer of membrane nitrogen systems, com- bustion inert gas systems and hy- drogen recovery systems, Permea Maritime Protection, a division of Air Products A/S, has received a contract to supply what is report- edly the world's largest nitrogen generation system using mem- branes. The system is designed to generate 1,800 Sm3/h of nitrogen with a maximum oxygen content of 0.8 percent and will be installed in the Troll Onshore Gas Treatment and Recompression Plant, located at Kollsnes in Oygarden, 50 km northwest of Bergen, Norway. The contract was awarded by A/S Norske Shell, development operator for Troll Project, phase I. "This contract is very promising for the forthcoming use of mem- branes in large nitrogen systems," says Arne Tag, offshore sales man- ager of Permea Maritime Protec- tion. "After thorough evaluation the client finds today's membranes to be technically sound." The Troll membrane system will be manufactured to the Troll Project standards in Kristiansand, Norway, and is scheduled for delivery in Sep- tember next year. Permea Maritime Protection has built more than 30 nitrogen systems to offshore standards and some 130 for shipboard use. The company's latest offshore delivery was the ni- trogen system for the Troll Olje plat- form.

Ericsson developed the model for Inmarsat, which is planning to in- troduce the Inmarsat-P global, digi- tal hand-held phone service using an advanced satellite system in the 1998-2000 time frame. Inmarsat is the London-based international mobile communications satellite operator. The model Inmarsat-P was pre- sented by Ericsson at the CNIT in La Defense, Paris, on the closing day of the Second Inmarsat Inter- national Conference and Exhibition on Mobile Satellite Communications.

Inmarsat M can transfer data and fax as well as voice, but is particu- larly useful for telephone service. Although suited for all maritime communication, Inmarsat M could become the preferred choice for smaller craft, including the fishing fleet, currently not using satellite communication because of the costs. Inmarsat M covers most of the globe, including the Indian Ocean. The Atlantic Ocean is served by Brit- ish Telecom, and by the interaction of Singapore Telecom, full coverage of the Pacific Ocean will be reached by mid-1994.
