Metoda za određivanje pomaka sidra (1), navedena metoda uključuje sljedeće korake: (a) određivanje početne pozicije sidra; (b) određivanje pomaka sidra: i. mjerenjem brzine sidra putem senzora brzine, posebno ultrazvučnog Dopplerovog senzora brzine ili senzora brzine temeljenog na obradi slika, ii. mjerenjem barem još jedne mjerne veličine povezane sa sidrenjem radi određivanja pomaka sidra (1), iii. određivanjem je li sidro u mirovanju ili pokretu, pri čemu se vrijednost dodatne mjerne veličine uzima u obzir pri donošenju odluke, iv. tijekom intervala kada se smatra da je sidro u pokretu, integrirajući vrijednosti brzine tijekom vremena kako bi se odredio pomak sidra(1).
2. Metoda prema zahtjevu 1, dodatno uključuje sljedeće korake: (a) ignoriranje i/ili odbacivanje vrijednosti brzine sidra izmjerene tijekom intervala kada se smatra da je sidro u mirovanju, i/ili (b) isključivanje senzora brzine, posebno privremeno prekidajući napajanje senzora brzine ili stavljanjem senzora brzine u stanje mirovanja ili stanje niske potrošnje energije u kojem se, posebno u usporedbi s normalnim stanjem rada senzora brzine, troši i/ili pruža smanjena količina energije senzoru brzine.
3. Metoda prema zahtjevu 1, dodatno uključuje korak korekcije integracije vrijednosti brzine temeljem vrijednosti brzine sidra izmjerene tijekom intervala kad se smatra da je sidro u mirovanju.
4. Metoda prema jednom od prethodnih zahtjeva, gdje korak mjerenja barem još jedne mjerne veličine uključuje mjerenje vibracija sidra, mjerenje sile koja djeluje na sidro putem sidrenog kabela (3), mjerenje podvodnog tlaka na lokaciji sidra i/ili mjerenje udaljenosti između sidra i fiksne referentne točke, posebno mjerenje udaljenosti između sidra i plovila (2), i/ili mjerenje nagiba ili orijentacije sidra.
5. Metoda prema jednom od prethodnih zahtjeva, dodatno uključuje korak aktiviranja senzora brzine kada mjerenja putem pomoćnih senzornih sredstava ukazuju na to da je ispunjen unaprijed određeni uvjet, posebno kada izmjerene vrijednosti podataka dobivenih putem pomoćnih senzora premaše unaprijed određeni ili prethodno podešeni prag.
6. Metoda prema jednom od prethodnih zahtjeva, gdje korak aktivacije senzora brzine uključuje prijelaz senzora brzine iz isključenog stanja, stanja niske potrošnje ili stanja mirovanja u normalno stanje napajanja, u kojem se preferirano troši nominalna količina energije od senzora brzine, osobito ponovnim povezivanjem ili uspostavom napajanja senzora brzine.
7. Metoda za praćenje pouzdanosti sidrenja, metoda uključuje sljedeće korake: (a) Određivanje pomaka sidra (1) prema jednom od navedenih zahtjeva od 1 do 7, i (b) generiranje upozoravajuće poruke ili signala ako pomak premašuje unaprijed određeni alarmni prag.

10. Sustav sukladno zahtjevu 8 ili 9, gdje pomoćna senzorna sredstva uključuju jedinicu za detekciju vibracija konfiguriranu za primanje podataka o brzini od sredstva za dobivanje podataka o brzini i za mjerenje vibracija, posebno intenziteta i/ili amplitude vibracija, sidra izvlačeći podatke o vibracijama iz podataka o brzini.
11. Sustav prema jednom od zahtjeva 8 do 10, dodatno uključuje sredstva za prikazivanje (22) konfigurirana za prikaz, posebno putem grafičkog prikaza, pomaka i/ili apsolutnog kretanja, npr. apsolutne vrijednosti pomaka, sidra, posebno kao funkcije vremena, sile, položaja, udaljenosti, dubine i/ili orijentacije.
12. Sustav prema jednom od zahtjeva od 8 do 11, konfiguriran za generiranje upozoravajuće poruke ili signala ako pomak, posebno apsolutna vrijednost pomaka, premaši unaprijed određeni alarmni prag.
