Abstract

A water-borne vessel for deploying a self-standing riser system is provided, wherein the vessel hull is configured to receive, transfer and deploy components of a self-standing riser system. The vessel hull includes at least a landing platform, a component transfer means, and a deployment platform suitable for deploying the riser components into associated surrounding waters. Various means of assisting the process whereby self-standing riser components are loaded onto the vessel and stored; transferred from receiving to deployment platforms; and deployed from the vessel into surrounding waters are also considered.

Claims

1. A water-borne vessel for deploying a self-standing riser system, said vessel comprising:

a vessel hull configured to receive, transfer and deploy components of a self-standing riser system, wherein said vessel hull further comprises a landing platform, a transfer means, and a deployment platform.

2. The water-borne vessel for deploying a self-standing riser system of claim 1, wherein said landing platform further comprises a hoisting means.

3. The water-borne vessel for deploying a self-standing riser system of claim 1, wherein said landing platform further comprises an intake port for flooding said receiving platform.

4. The water-borne vessel for deploying a self-standing riser system of claim 1, wherein said transfer means further comprises means for transferring self-standing riser components from said receiving platform to said deployment platform.

5. The water-borne vessel for deploying a self-standing riser system of claim 4, wherein said transferring means further comprises a securing means for securing said components during transfer from said receiving platform to said deploying platform.

6. The water-borne vessel for deploying a self-standing riser system of claim 1, wherein said deployment platform further comprises a receiving means for receiving self-standing riser components transferred from said receiving platform.

7. The water-borne vessel for deploying a self-standing riser system of claim 1, wherein said deployment platform further comprises a securing means for securing self-standing riser components received from said transferring means.

8. The water-borne vessel for deploying a self-standing riser system of claim 1, wherein said deployment platform further comprises a hoisting means for hoisting self-standing riser components received from said transferring means into a deployment position.

9. The water-borne vessel for deploying a self-standing riser system of claim 1, wherein said deployment platform further comprises a deployment means for deploying self-standing riser components from said deployment platform into associated surrounding waters.

10. The water-borne vessel for deploying a self-standing riser system of claim 1, wherein said water-borne vessel further comprises a storage area for storing self-standing riser components placed upon said vessel.
