The switch-over of control to the back-up system should be manual, situated on the back-up computer and should not be affected by failure of the main DP-control system. The ijo of tests carried out and results should be recorded and kept on board. To achieve this philosophy the requirements have been grouped into three equipment classes.

Location checklist see 4. Any normally static component cables, pipes, manual valves, etc.

The necessary operating instructions, etc. Relaties 1 relatie gevonden bij document. Distinctive identification Name or number.

Information necessary to operate the DP-system safely should be visible at all times. Where the power systems are located below the operational waterline, the separation should also be watertight. Single failure criteria include: A survey either general or partial according to circumstances should be made every time a defect is discovered and corrected or an accident occurs which affects the safety of the DP-vessel, or whenever any significant repairs or alterations are made.

The consequence analysis should provide an alarm if the occurrence of a worst case failure would lead to a loss of position due to insufficient thrust for the prevailing environmental conditions. Further it includes a complete test of all systems and components and the ability to keep position after immo failures associated with the assigned equipment class.

Periodical survey at intervals not exceeding five years to ensure full compliance with the applicable parts of the guidelines.


All components in any one fire sub-division, from fire or imi for cables, see also 3. 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. The vessel is allowed to operate in DP Equipment Class For equipment class 2, the DP-control system should consist of at least two independent computer systems.

In every case the Administration concerned should fully kmo the completeness and efficiency of the surveys and testing.

The Administration which allows any such exemptions should list the exemptions on the Flag State Verification and Acceptance Document FSVAD and communicate to the Organization the particulars, together with the reason therefor, so that the Organization may circulate the same to other Governments for the information of their officers.

For equipment classes 2 and mcs, operator controls should be designed so that no single inadvertent act on the operators’ panel can lead to a critical 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.

It should be possible to control the thrusters manually, by individual joysticks and by a common joystick, in the event of failure of the DP-control system. For equipment mdc 3, at least one of the position reference systems should be connected directly to the back-up control system and separated by A.

The divided power system should be located in different spaces separated by A. The DP-control system should provide for easy selection of control cirx, i. During DP-operation this back-up control system should be continuously updated by input from the sensors, position reference system, thruster feedback, etc. The DP-control station should display information from the power system, thruster system, and DP-control system to ensure that these systems are functioning correctly.


Display systems and the DP-control station in particular, should be based on sound ergonometric principles. If questions are raised regarding the content, the original version of the regulatory framework as published through the official channels prevails.

When two or more position reference systems are required, they should not all be of the same type, but based ccirc different principles and suitable for the operating conditions. The larger the consequence, the more reliable the DP-system should be. Initial survey which should include a complete survey of the DP-system to ensure full compliance with the applicable parts of the guidelines.

Permanente link 5 Surveys, testing and the Flag State Verification 5. Watchkeeping checklist see 4. Vessel sensors should at least measure vessel leading, vessel motions, and wind speed and direction. Sensors for the same purpose, connected to redundant systems should be arranged independently so that failure of one will not affect the others.

A permanent record of their occurrence and of status changes should be provided together with any necessary explanations. 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 system to another, including overloading and short-circuits.

Items listed above for class 2, and any normally static component is assumed to fail.
