The strength of anchors and their holding power should be able to be documented with the basis in calculations or samples. The calculations shall take into account the current conditions and any previous tests.

11. If the ankerlinelengde is thought to be able to be adjusted depending on the weather conditions (active docking system) should this operation be tested out and documented, for current conditions. For such system it should be possible to schedule the alignment on board with simulation tools. Normally, to be able to run without winches, this leads to shutdown of other critical systems.

16. It shall not be possible to release the ankerliner when the risers are connected to the device. It should be a separate protection system that prevents this. Need to be possible, however, to ejaculation with risers connected after manual UN foregoing protection system. Risk analysis according to the Maritime's then-current regulations on risk analysis to determine whether there is a need for the frakoplings mechanism for the risers, and under what dimensjonerende events of the accident so disconnecting is needed.

17. The maximum fluctuations of the device in the intact condition and after any single error or double error shall not exceed a maximum of fluctuations that riser is dimensioned to withstand. It will be used a safety margin on 2.5% of water depths for rigid risers, while for flexible risers applied a safety margin of 5% of the water.
