<p>An overtrawlable protection envelope (E) for a subsea structure (F, T) which is connected to the seabed wherein the envelope (E) is anchored by connecting it to the subsea structure (F, T) which it is to protect. The envelope (E) may be defined by four legs (3, 14) pivotally deployable from folded positions to deployed positions during installation. Each leg may include separate upper and lower portions (3, 14) when used to protect a two-part structure such as one comprising a flowbase (F) and a tree (T). The legs may also have telescopic parts (4, 15).</p> |
