Ships Correctable Stairs
Scope of Work: To design and fabricate a 20-mtr set of aluminium correctable stairs for the disembarkation of Oil tankers at Townsville Wharf.
Key Elements:
Design and certify in accordance with ISO7061
Allow operating angle of 45Deg+
Be mobile for manual positioning on the wharf
DWW were engaged to design a method allowing staff to disembark vessels at the Townsville wharf, with a wharf width restriction of 20-mtr. The restricted width meant that a gang-plank couldn’t be used (max 30deg incline) so a set of self-correcting steps were design to operate at 45deg+ incline.
Basically as a ship rises and falls with the tide level and ballast amounts the stairs self-correct to always provide a level step for safe use, that conforms with ISO7061.
