Guidelines for vessels with dynamic positioning systems (MSC Circular ) – IMCA

In this context deterioration of environmental conditions and the necessary time to safely terminate the operation should also be taken into consideration. The Administration may entrust the owner of the vessel to carry out annual and minor repair surveys 6445 to a test programme accepted by the Administration.

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 be transferred from one cjrc to another, including im and short-circuits. See Appendix for model form. Permanente link Huidige versie Meest ccirc versie. An uninterruptible power supply UPS should be provided for each DP-computer system to ensure that any power failure will not affect more than one computer. All components in any one fire sub-division, from fire or flooding for cables, see also 3.

Distinctive identification Name or number. As an alternative reference can be made to drawings, etc. In every case the Administration concerned should fully guarantee the completeness and efficiency of the surveys and testing. All components in any one watertight compartment, from fire or flooding. Initial and periodical 5-year tests and procedures see 5. Watchkeeping checklist see 4. A survey either general or partial according to circumstances should be made every time a defect is discovered and mio or an accident occurs which affects the safety of the DP-vessel, or whenever any significant repairs or alterations are made.

Display systems and the DP-control station in particular, should be based on sound ergonometric principles. Permanente link Permanente link 4 Operational requirements 4. This document remains valid until For equipment class 3, the back-up DP-control system should be in a room separated by A. circc

The divided power system should be located in different ms separated by A. UPS battery capacity should provide a minimum of 30 minutes operation following a mains supply failure.

The DP-control system should prevent failures being transferred from one system to another. It should be possible to control io thrusters manually, by individual joysticks and by a common joystick, in the event of failure of the DP-control system. For each equipment class the associated worst case failure should be defined as in 2.

To achieve this philosophy the requirements have been grouped into three equipment classes.

Items listed above for class 2, and 6445 normally static component is assumed to fail. Annual tests and procedures see 5. This should be checked by way of environmental envelopes if operating in equipment class 1 and by way of an automatic consequence analysis if operating in equipment class 2 or 3.

Where this is unavoidable such cables could run together in cable ducts of A class, the termination of the ducts included, which are effectively protected from all fire hazards, except that represented by the cables themselves.

Bus-tie breakers should be open during equipment class 3 operations unless equivalent integrity of power operation can be accepted according to 3.

Failure in one system should in no case be transferred to the other redundant system. Permanente link Permanente link 2 Equipment classes 2. Permanente link 1 General 1. After such a survey, necessary tests should be carried out to demonstrate full compliance with the applicable provisions of the Guidelines.

Redundancy can be io for instance by installation of multiple components, systems or alternative means of performing a function. Any normally static component cables, pipes, manual valves, etc.
