(54)	OBSTRUCTION FOR USE WITH SECURITY BULWARKS, PERIMETER PROTECTION SYSTEM AND METHOD OF PROTECTING A PERIMETER

(57) In one aspect, the present invention provides an obstruction (80A, 80B) for positioning in a recess (90) between an adjacent pair of security bulwarks (1a, 1b, 1c, 30) mounted outside a perimeter railing (20) of a vessel or marine installation. The obstruction comprises a rear end (81) for positioning towards the perimeter railing, a front end (83) for positioning away from the perimeter railing, and a top side (82), an underside (84) and a pair of opposing lateral cheeks (85a, 85b) separating the front end (83) from the rear end (81). In addition, the obstruction comprises a connection facility (87, 88) for connecting the obstruction to at least one of the perimeter railing and the adjacent pair of security bulwarks. The top side (82) slopes downwardly from the rear end towards the front end during use of the obstruction between an adjacent pair of security bulwarks, so that a hand of an unauthorized potential boarder placed on the top side (82) of the obstruction will tend to slide off it in a seaward direction. The invention also provides a perimeter protection system (800A, 800B) comprising such an obstruction (80A, 80B), and a method of protecting a perimeter of a vessel or marine installation using such an obstruction.
