EFFICIENT OPEN WATER RISER DEPLOYMENT |
摘要 |
<p>A riser for use in subsea operations that is parked subsea deployed as needed onto wellheads disposed proximate where the riser is parked. A base anchored into the seafloor provides a pedestal for parking the riser. The riser emits a beacon signal so it can be located when needed. When parked, the riser can be kept in a vertical orientation by a buoyancy module mounted on an upper portion of the riser. A workboat, or other vessel, attaches to the parked riser and positions it onto a designated wellhead. An extension connects the riser to platform or other vessel above the sea surface.</p> |
