Preamble These Guidelines for vessels with dynamic positioning systems have been developed to provide an international standard for dynamic im systems on all types of new vessel. Permanente link 5 Surveys, testing and the Flag State Verification 5. A permanent record of their occurrence and of status changes should be provided together with any necessary explanations.

All components in any one watertight compartment, from fire or flooding.

Position reference systems should be selected with due consideration to operational requirements, both with regard to restrictions caused by the manner of deployment and expected performance in working situation.

The Administration may entrust the owner of the vessel to carry out annual and minor repair surveys according to a test programme accepted by the Administration. In every case the Administration lmo should fully guarantee the completeness and efficiency of the surveys dirc testing. For equipment class 3, the DP-control system should consist of at least two independent computer systems with self-checking and alignment facilities.

The divided power system should be located in different spaces separated by A. Member Governments are also invited to use the proposed model form of flag State verification and acceptance document set out in the appendix to the Guidelines.

Initial survey which should include a complete survey of cird DP-system to ensure full compliance with the applicable parts of the guidelines. Further it includes a complete test of all systems and components and the ability to keep position after single failures associated with the assigned equipment class. Initial and periodical 5-year tests and procedures see 5. Permanente link 1 General 1. The equipment class of the vessel required for a particular operation should be agreed between the owner of the vessel and the customer based on a risk analysis of the consequence of a loss of position.


Periodical survey at intervals 6645 exceeding five years to ensure full compliance with the applicable parts of the guidelines. Permanente link Permanente link 4 Operational requirements 4. For equipment classes 2 and 3, operator controls should be designed so that no single inadvertent act on the operators’ panel can lead to a critical condition.

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. Taking into account that dynamically positioned vessels are moved and operated internationally and recognizing that the design and operating criteria require special consideration, the Guidelines have been developed to facilitate international operation without having to document the dynamic positioning system in detail for every new area of operation.

Annual survey should be carried out within three months before or after each anniversary date of the initial survey. For equipment class 2, the DP-control system should consist of at least two independent computer systems. Distinctive identification Name or number. Location checklist see clrc.

The thruster system includes: For each equipment class the associated worst case failure should be defined as in 2. For equipment class 2, a loss of position is not to occur in mec event of a single fault in any active component or system.

This imp 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. Normally static components will not be considered to fail where adequate protection from damage is demonstrated, and reliability is to the satisfaction of the Administration.

Redundancy can be achieved for instance by installation of multiple components, systems or alternative means of performing a function. Ga direct naar Inhoud of Menu. The consequence analysis should provide an alarm if the occurrence of a worst case failure would lead to a loss ccirc position due to insufficient thrust for the prevailing environmental conditions. Daar kan niet mee worden vergeleken. The Administration may, however, entrust the surveys and testing either to surveyors nominated for the purpose or to organizations recognized by it.

Items listed above for class 2, and any normally static component is assumed to fail. Relaties 1 relatie gevonden bij document. Further an annual test of all important systems and components should be carried out to document the ability of the DP-vessel to keep position after single failures associated with the assigned equipment class.


Sensors for the same purpose, connected to redundant systems should be arranged independently so that failure of one will not affect the others. The type of tests carried out and results should be recorded and kept on board. The transfer should be smooth and within acceptable limitations of the operation. When an equipment class 2 or 3 DP-control system is fully dependent on correct signals from vessel sensors, then these signals should be based on three systems serving the same purpose i.

For operations which will take a long time to safely terminate, the consequence analysis should include a function which simulates the thrust and power icrc after the worse case failure, based on manual input of weather trend.

The position reference systems should produce data with adequate accuracy for the intended DP-operation. Such connections should be kept to the absolute minimum and made to fail to the safest condition. Failure in one system should in no case be transferred to the other redundant system. UPS battery capacity should provide a minimum of 30 minutes operation following a mains supply failure. 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.

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. Geldig vandaag Dit onderwerp bevat de volgende rubrieken.

Display systems and the DP-control station in particular, should be based on sound ergonometric principles. I,o normally static component cables, pipes, manual valves, etc.

See Appendix for model form. For equipment classes 2 and 3, the DP-control system should include a software function, normally known as ‘consequence analysis’, which continuously verifies that the vessel will remain in position even if the worst case failure occurs. It is important that it is possible.
