T/NSSQ 015-2022 Design Requirements for the Centralized Alarm Control and Monitoring System of Semi-Submersible Ships
T/NSSQ 015-2022 The design requirements for a semi-submersible ship central alarm control and monitoring system
Basic Information
Scope
Scope: This document is applicable to the design of the centralized alarm control and monitoring system for semi-submersible ships with DP-2 symbols and AUT-0 automatic additional markings. Note 1: DP-2 symbols refer to semi-submersible ships equipped with dynamic positioning systems, which can automatically maintain their position and heading within specified environmental conditions and operational ranges after a single failure (excluding the loss of a single or multiple compartments). Note 2: AUT-0 automatic additional markings refer to semi-submersible ships where the propulsion system is remotely controlled by the bridge control station, and the engine room, including the engine room control station (room), is periodically unmanned. Main technical content: This document specifies the design basis, design principles, overall design requirements, detailed design requirements, and design verification for the centralized alarm control and monitoring system of semi-submersible ships.
