Example of tests and procedures after modifications and non-conformities see 5. An alarm should be initiated if any computer fails or msd not ready to take control.
Permanente link 1 General 1. This document remains valid until The transfer should be smooth and within acceptable limitations of the operation. DP-operation instructions see 4.
For equipment classes 2 and 3, at least three position cirrc systems should be installed and simultaneously available to the DP-control system during operation.
Redundant computer systems should be arranged with automatic transfer of control after a detected failure in one of the computer systems. Permanente link Preamble These Guidelines for vessels with dynamic positioning systems have been developed to provide an international standard for dynamic positioning systems on all types of new vessel. For equipment class 1, loss of position may occur in the event of a single fault.
In every case the Administration concerned should fully guarantee the completeness and efficiency of the surveys and testing. For equipment class 3, the back-up DP-control system should be in a room separated by A. Beschrijving Guidelines for vessels with dynamic positioning systeems. For equipment class 3, a single failure includes: These Guidelines for vessels with dynamic positioning systems have been developed to provide an international standard for dynamic positioning systems on all types of new vessel.
Initial survey which should include a complete survey kmo the DP-system to ensure full compliance with the applicable parts of the guidelines. The performance of position reference systems should be monitored and warnings provided when the signals from the position reference systems are either incorrect or substantially degraded. Such connections should be kept to the absolute minimum and made to fail to the safest condition.
Any such vessels should, however, comply with safety requirements which, in the opinion of the Administration, are adequate for the service intended and are such as to ensure the overall safety of the vessel.

Annual survey should be carried out within three months before or after ino anniversary date of the initial survey. During DP-operation this back-up control system should be continuously updated by input from the sensors, position reference system, thruster feedback, etc. Bus-tie breakers should be open during equipment class 3 operations unless equivalent integrity of power operation can be accepted according to 3.
Any active component or crc generators, thrusters, switchboards, remote 64 valves, etc. This analysis should verify that the thrusters msv in operation after the worst case failure can generate the same resultant thruster force and moment as required before the failure. For operations which will take a long time to safely terminate, the consequence analysis should include a function which simulates the thrust and power remaining after the worse case failure, based on manual input of weather trend.
To achieve this philosophy the requirements have been grouped into three equipment classes. If questions are raised regarding the content, the original version of the regulatory framework as published through the official channels prevails. Else, the Administration or coastal State may decide the equipment class for the particular operation. The power system may be run as one system during operation, but should be arranged by bus-tie breakers to separate automatically upon failures which could iml transferred from one system to another, including overloading and short-circuits.

The annual survey should ensure that the DP-system has been maintained in accordance with applicable parts of the guidelines and is in good working order. Permanente link 3 Functional requirements 3.
