1. A walk-to-work system for allowing personnel and/or equipment to move between a vessel and a wind turbine, wherein the walk-to-work system comprises:
a gangway system comprising:
a height adjustable elongated pedestal having a first elongated pedestal end mountable onto a deck of the vessel, the height adjustable elongated pedestal comprising: a first pedestal part and a second pedestal part height adjustably coupled to the first pedestal part, and
a gangway rotationally coupled to the height adjustable elongated pedestal at a height Hg from the first elongated pedestal end such that the gangway is radially extending at a length Lg from a center axis of the height adjustable elongated pedestal,
an elevator system positioned with a radial offset from the gangway system, the elevator system comprising:
a height adjustable elongated elevator having a first elevator end mountable onto the deck of the vessel,
the height adjustable elevator comprising: a static elevator part and a displaceable elevator part height adjustably coupled to the static elevator part,
a drive system configured to displace the displaceable elevator part relative to the static elevator part along the elevator's height,
an elevator car movably connected to the height adjustable elevator, wherein the elevator car is configured to be elevated up to the same height as the gangway for allowing access between the elevator system and the gangway system, and
a lifting device configured to move the elevator car of the height adjustable elevator.
