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.

The necessary operating instructions, etc. Beschrijving Guidelines for vessels with dynamic positioning systeems. For equipment class 3, at least one of the position reference systems should be connected directly to the back-up control system and separated by A. Permanente link Permanente link 2 Equipment classes 2.

Display systems and the DP-control station in particular, should be based on sound ergonometric principles. All components in any one fire sub-division, from fire or flooding for cables, see also 3. This document remains valid until Where this in unavoidable, such pipes could run together in ducts of A class, the termination of the ducts included, which are effectively protected from all fire hazards, except that represented by the pipes themselves.

Bus-tie breakers should be open during equipment class 3 operations unless equivalent integrity of power operation can be accepted according to 3. Annual tests and procedures see 5.

Guidelines for vessels with dynamic positioning systems (MSC Circular 645)

Other information should be available upon operator request. 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.

Else, the Administration or coastal State may cidc the equipment class for the particular operation. Cable connection boxes are not allowed in such ducts.

The DP-control system should provide for easy selection of control mode, i. The redundant components should be so arranged that a failure of one component should be isolated, and the other component activated.

The power system includes: As an alternative reference can be made to drawings, etc. Redundancy can be achieved for instance by installation of multiple components, systems or alternative means of performing a function.

Information necessary to operate the DP-system safely should be visible at all times. To achieve this philosophy the requirements have been grouped into three equipment classes.

Single failure criteria include: See Appendix for model form. The Administration may, however, entrust the surveys and testing either to surveyors nominated for the purpose or to organizations recognized by it.

Where the power systems are located below the operational waterline, the separation should also be watertight. 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 equipment classes immo and 3, at least three position reference systems should be installed and simultaneously available to the DP-control system during operation. If questions are raised regarding the content, the original version of the regulatory framework as published through the official channels prevails.

Non-redundant connections between otherwise redundant and separated systems may be accepted provided that it is documented to give clear safety advantages, and that their reliability mac be demonstrated and documented to the satisfaction of the Administration.

The larger the consequence, the more reliable the DP-system should be.
