A subsea drilling template |
摘要 |
<p>A subsea drilling template (20) is adapted to be lowered onto a seabed (22) by a drill pipe (24). The template (20) comprises a template base (28) and arm(s) (30) having a releasable clamping assembly (42) for releasably connecting the template (20) to the drill pipe (24). The clamping assembly (42) is adapted to be clamped to the drill pipe (24) during lowering of the template (20) and release from the drill pipe (24) when the lowering is completed. This allows drilling to commence immediately after the template has been positioned and therefore a single trip is all that is required to the seabed.</p> |
