Delivery of the self-propelled pipelay/derrick ship Sea Troll, which Blohm & Voss are building for the French/Norwegian company Sea Troll A/S of Oslo, is planned for late 1976. Her design is based on that of the ETPM 1601 (which has completed a year's operation in the North Sea), but she has pipelaying machinery of increased capacity, together with a third tensioner winch. The article gives an outline description of Sea Troll's communications installation, one of the most comprehensive ever fitted to a vessel of this type and consisting of radio communications, automatic telephone exchange, command intercom, public address (which also serves for general alarm), communal aerial, fire alarms, closed-circuit TV monitoring, and entertainments systems. These systems were all supplied by United Marine Electronics A.S. The radio station will be the most advanced in the Norwegian Merchant Marine, and will have four simultaneous RT and three telex circuits. All the transmitters (MF/CT and HF) are housed in a special room, with remote control from the radio control-room; this arrangement is an innovation in Norwegian ships. The article includes further information on the transmitting and receiving equipment, including the arrangement of the many antennae. Bridge equipment includes two VHF RT transceivers, an MF radio-telephone for ship-to-ship work, and a VHF transceiver for ship/helicopter communication. Other equipment mentioned includes a radio direction-finder and an MF radio beacon.
