Abstract
A spread mooring arrangement is provided for use in deep water (greater than 200 meters) when it is advantageous to maximize the clearance between shuttle tankers (20) used for product off loading and the anchor legs associated with a spread mooring of the permanently moored tanker (10). Mooring insert tubes are provided at the bow and stern of the vessel. Bow mooring lines (30) extend from the sea floor through an opening of the bottom of the hull of the vessel and via a bow mooring insert tube (100) for securement on a chain pull-up deck (15). Stern mooring lines (40) extend from the sea floor through an opening in the bottom of the hull of the vessel and via a stern mooring insert tube (120) for securement on a chain pull-up deck (15). Space is available on one side of the vessel for a porch (65) for securement of production risers (70), work over risers and control umbilicals, thereby providing flexibility of the use of the vessel for the circumstance where production methods for the oil field change during its leftime or where other fields need to be coupled to the vessel with risers.

PATENT APPLICATION
TITLE: DOUBLE POINT MOORING SYSTEM
BACKGROUND O>= TH[,~ INVENTION
Cross Reference To Related A~~lication This application claims the priority filing date of U.S. Provisional application 601051,959 filed 07/08/97.
Field of the Invention This invention relates in general to mooring arrangements for vessels and in particular to a spread mooring arrangement for a permanently moored storage vessel to which a shuttle tanker is tied up along side during product transfer.
Description of the Prior Art A shuttle tanker tied up beside a permanently moored storage tanker needs clearance between its hull and the anchor legs of the storage tanker.
There are many permanent mooring arrangements for storage tankers yet, a possibility exists for shuttle tanker entanglement with anchor legs of the permanently moored vessel, especially if anchor legs are secured mid-way between its stern and its bow or if anchor legs are secured mid-way between its stern and its bow or if anchor legs extend from the deck via the side of the vessel.
Identifrcation of Objects of the Invention it is an important objective of the invention to provide a mooring arrangement for permanently mooring a storage tanker in deep water (greater than 200 meters) which substantially prevents the possibility of entanglement of the shuttle tanker with the anchor legs of the storage tanker.
Another object of this invention is to provide a spread mooring at the bow end and the stern end of the vessel to allow large shuttle vessels to be tied up alongside the storage vessel in moderate environments for offloading of hydrocarbon product without the potential to entangle the permanently installed anchor legs of the storage vessel Another object of this invention is to provide a double point mooring system for large vessels to be tied up together in moderate environments for offloading product from one vessel to another while providing space on the side of the storage vessel for the securement of production risers, work over risers or control umbilicals.
SUMMARY OF THE INVENTION
In shallow water, spread mooring systems have been used. The anchor legs of such spread mooring systems have normally been deployed from a top deck of the vessel from its sides, bow or stern. Placement of such spread anchor legs is likely to cause entanglement of a shuttle tanker when it is maneuvered for tying up the side of the storage vessel.
According to the invention, a double spread mooring system is provided, one at the stern, the other at the bo~ni of the storage vessel for deep water (greater than 200 meters) applications. Such placement of anchor legs away from mid-way between stern and bow provides a certain level of clearance of a shuttle tanker tied up to the side of the storage vessel. The bow and stern anchor legs enter the vessel not from the deck of the bow or stern or from its sides, but rather from beneath the vessel via a mooring insert tube through which anchor chains are pulled in from winches on the deck of the vessel. Because the anchor legs approach the vessel from the bottom of its keel, a further level of clearance is provided for deep water applications, which substantially insure that a shuttle tanker will not become entangled with the anchor legs.
BRIEF DESCRIPTION OF THE DRAWINGS
The various objects and advantages of this invention will become apparent to those skilled in the art upon an understanding of the following detailed description of the invention, read in light of the accompanying drawings which are made a part of this specification and in which:
In the Drawings:
Figure 1 is a plan view of a permanently moored vessel with a double point mooring arrangement according to the invention with a shuttle tanker tied up along its side;
Figure 2 is a cross sectional view taken along sections lines A-A of Figure 1 which illustrates anchor legs at the stern of the vessel entering a mooring insert tube of the vessel; and Figure 3 illustrates the mooring insert tube of the mooring arrangement of the invention.
DESCRIPTION OF THE PREFERRED
EMBODIMENT OF THE INVENTION
A plan view is presented in Figure 1 of a permanently moored storage vessel 10 having a shuttle tanker 20 (shown fully loaded) tied up along its side for loading of product. Rubber fenders 50 protect the vessels from damage while being tied to each other. Flexible hoses 60 provide product flow paths from the permanent storage vessel 10 and the shuttle tanker 20.
The storage vessel 10 is moored to the sea bed by a double spread mooring arrangement comprising anchor legs 30 at the bow and anchor legs 40 at the stern rather than a single anchor leg pattern connected mid-way between bow and stern. The anchor legs are terminated at the sea floor by anchors. Such anchors may be of any of several known types in the art of mooring systems. Anchor legs 30 may include lengths of chain and wire or synthetic rope as well known in the art of mooring systems.
Anchor legs 30 at the bow are secured to vessel 10 by entering at a bottom end of a bow insert tube 100 which is placed on the longitudinal center line of the hull of the vessel and extends from the vessel deck 15 (or a chain pull-up deck) to the keel of the vessel. Each anchor leg 30 is pulled in and secured to the chain pull-up deck 15 of the vessel 10 by a double drum winch 17. Likewise, anchor legs 40 at the stern are secured to vessel by entering at a bottom end of a stern insert tube 120 which is similar in construction to tube 100. Each anchor leg 40 is pulled in and secured to the chain pull-up deck 15 of the vessel 10 by a double drum winch 19. Different chain pull-up decks may be used under certain circumstances.
10 Figure 2 illustrates the two vessels 10 and 20 in a cross-section view along lines A-A of Figure 1. Because anchor legs 40 enter the insert tube 120 from beneath the permanently moored vessel 10, rather than from its side or the top of its bow or stern, and because the anchor legs 30 and the anchor legs 40 are connected to storage vessel 10 at its bow and stern, not mid-way between bow and stern, the shuttle tanker 20 has sufficient clearance from anchor legs 40 and anchor legs 30 to insure that there will not be entanglement.
The section view of Figure 2 further illustrates a riser porch 65 provided along the side opposite that to which the shuttle tanker 20 is tied up. Riser porch 65 provides a structure where production risers and control umbilicals 70 may be run and secured to the permanently moored vessel 10. Such riser porch 65 may be provided mid-way between stern and bow.

BRIEF DESCRIPTION OF THE DRAWINGS
The various objects and advantages of this invention will become apparent to those skilled in the art upon an understanding of the following detailed description of the invention, read in light of the accompanying drawings which are made a part of this specification and in which:
In the Drawings:
Figure 1 is a plan view of a permanently moored vessel with a double point mooring arrangement according to the invention with a shuttle tanker tied up along its side;
Figure 2 is a cross sectional view taken along sections lines A-A of Figure 1 which illustrates anchor legs at the stern of the vessel entering a mooring insert tube of the vessel; and Figure 3 illustrates the mooring insert tube of the mooring arrangement of the invention.
DESCRIPTION OF THE PREFERRED
EMBODIMENT OF THE INVENTION
A plan view is presented in Figure 1 of a permanently moored storage vessel 10 having a shuttle tanker 20 (shown fully loaded) tied up along its side for loading of product. Rubber fenders 50 protect the vessels from damage while being tied to each other. Flexible hoses 60 provide product flow paths from the permanent storage vessel 10 and the shuttle tanker 20.
The storage vessel 10 is moored to the sea bed by a double spread mooring arrangement comprising anchor legs 30 at the bow and anchor legs 40 at the stern rather than a single anchor leg pattern connected mid-way between bow and stern. The anchor legs are terminated at the sea floor by anchors. Such anchors may be of any of several known types in the art of mooring systems. Anchor legs 30 may include lengths of chain and wire or synthetic rope as well known in the art of mooring systems.
Anchor legs 30 at the bow are secured to vessel 10 by entering at a bottom end of a bow insert tube 100 which is placed on the longitudinal center line of the hull of the vessel and extends from the vessel deck 15 (or a chain pull-up deck) to the keel of the vessel. Each anchor leg 30 is pulled in and secured to the chain pull-up deck 15 of the vessel 10 by a double drum winch 17. Likewise, anchor legs 40 at the stern are secured to vessel by entering at a bottom end of a stern insert tube 120 which is similar in construction to tube 100. Each anchor leg 40 is pulled in and secured to the chain pull-up deck 15 of the vessel 10 by a double drum winch 19. Different chain pull-up decks may be used under certain circumstances.
10 Figure 2 illustrates the two vessels 10 and 20 in a cross-section view along lines A-A of Figure 1. Because anchor legs 40 enter the insert tube 120 from beneath the permanently moored vessel 10, rather than from its side or the top of its bow or stern, and because the anchor legs 30 and the anchor legs 40 are connected to storage vessel 10 at its bow and stern, not mid-way between bow and stern, the shuttle tanker 20 has sufficient clearance from anchor legs 40 and anchor legs 30 to insure that there will not be entanglement.
The section view of Figure 2 further illustrates a riser porch 65 provided along the side opposite that to which the shuttle tanker 20 is tied up. Riser porch 65 provides a structure where production risers and control umbilicals 70 may be run and secured to the permanently moored vessel 10. Such riser porch 65 may be provided mid-way between stern and bow.
Advantageously, the riser porch placed to the side of the permanently moored vessel 10 provides a large area for the combination of risers for production, re-injection or control umbificals. This allows great flexibility and adaptability for the installation of such equipment in the event that production methods for the oil field were to change during its lifetime or in the event that adjacent production wells were to be required to be serviced by the vessel 10.
Figure 1 illustrates that a large deck space 16 is available for production processing equipment even where two mooring insert tubes 100, 120 are provided.
Figure 3 illustrates an anchor leg 30 being spooled onto the vessel by a drum winch 17. Each mooring insert tube assembly 100, 120 is welded into an existing tanker 10 structure, typically at an intersection of longitudinal and transverse bulkheads. The internal diameter of the mooring tubes may be three meters, for example. Typically four anchor legs per tube are provided as illustrated in Figures 1 and 2. This arrangement maintains the integrity of the tanks of the vessel and provides a way to introduce mooring loads into the tanker.
The drum winches 17, 19 are preferably double drum winches to facilitate the hook up of the anchor legs 30 or 40 as the case may be. A
chain-wire-chain anchor leg arrangement is illustrated in Figure 3, but of course other arrangements may be provided.

Although, the preferred embodiment of the double point mooring arrangement of Figures 1-3 is for a shuttle tanker 20 to be tied up along the side of the permanently moored vessel 10, the arrangement may be used for offloading systems at the bow and or stern of the vessel to better facilitate off loading. The same advantages of providing large clearance distances between the anchor legs 30, 40 and the off loading shuttle vessel reservoirs are achieved.
