Synthetic rope mooring

Synthetic (polyester) fibre-rope mooring service life

Ask Deckhand to screen a polyester fibre-rope mooring for service life — fatigue, creep and minimum tension — to the fibre-rope guidance.

Run it on Open Deck

What you can ask it to do

  • Screen a polyester fibre-rope mooring for fatigue, creep and minimum-tension limits.
  • Estimate service life and flag the governing failure mode.
  • Apply the fibre-rope stiffness behaviour (upper/lower bound) to the check.

Questions

Why are fibre-rope moorings checked differently?

Polyester rope has non-linear, time-dependent stiffness and creep, so service life is governed by fatigue, creep and minimum-tension limits rather than a single break-load check. Guidance such as API RP 2SM applies.

What does Deckhand report?

A service-life screen with the governing mode — fatigue, creep or minimum tension — and the assumptions on rope stiffness bounds.
