Abstract: A tubular installation apparatus (1) including a lay tower (2) mounted to a support structure (4). The lay tower (2) is configured to lower a tubular section along a firing line (L) extending along the lay tower (2). A magazine (3) is removably mounted to the lay tower (2) and configured to be pre-loaded with a plurality of tubular sections. A feed mechanism (23, 25) is configured to feed one or more tubular sections from the magazine (3) to the firing line (L) of the lay tower (2) for connection to the end of a catenary.

Abstract: A subsea clearance apparatus (1) includes a chassis (2), fore and aft skids (3, 4) spaced along a principal axis (P) of the apparatus (1), and a pair of flanks (22a, 22b) with a plurality of tines (5) depending from the flanks (22a, 22b). The tines (5) are spaced transversely with respect to the principal axis (P) and pitched toward the fore of the apparatus (1). In use, the chassis (2) is spaced from the seabed (S) by the skids (3, 4) as the apparatus (1) is propelled therealong such that the tines (5) engage and deflect away from the principle axis (P) obstructions which are larger than a predetermined size and which protrude by a predetermined amount from the seabed (S).
