Description

BACKGROUND OF THE DISCLOSURE

1. Field of Disclosure

The present disclosure relates to a vessel for transporting Liquefied Natural Gas (LNG), petroleum products, such as Marine Gas Oils (MGO), hydraulic fluids, distillates, bio-fuels, lubricants, water and performing cargo delivery over water, and, in particular, on the ocean, lakes, bays, sounds and inland waterways.

2. Description of the Related Art

LNG may be transported across the sea and along inland waterways using specially designed water-going vessels, including self-propelled vessels and barge that may be combined tugs (such as an Integrated Tug-Barge (ITB) or an Articulated Tug-Barge (ATB)). Typically, LNG transport vessels are designed to carry LNG (for hire by others) as their sole cargo. Thus, an LNG transport vessel is unable to resupply another vessel with non-LNG supplies, such as MGO, hydraulic fluids, distillates, bio-fuels, lubricants, and water. One or more additional vessels, trucks or other delivery methods are required to supply a vessel with non-LNG supplies.

Typically LNG transport vessels are designed to be compliant with regulations for their transport medium. LNG transport vessel may be designed for compliant operation as sea-going vessels or as inland waterway vessels.

Substantial cost is incurred by using two vessels to resupply a vessel in need of LNG and additional supplies. Involving two resupply vessels with a vessel to be resupplied requires coordination and timing of the resupply operation to prevent downtime and avoid conflicts. What is needed is a single vessel that can resupply the needs of the vessel requiring resupply. Additionally, most LNG transport vessels are designed for operation at sea. What is needed is a LNG transport vessel that is configured to deliver various cargos for both sea-going, lakes, bays, sounds and inland waterway operation.

DETAILED DESCRIPTION OF THE DISCLOSURE

Generally, the present disclosure relates to a water-going vessel for transporting LNG and at least one other cargo. Specifically, the present disclosure is related to transporting LNG and at least one other cargo, where the vessel is a barge configured to interlock with a tugboat, and where the cargo is a material required for resupply of a water-going vessel. The novel vessel is configured for “bunkering” operations (such as the resupply of consumables, fuel for propulsion or auxiliaries (e.g., generators)) to other vessels under weigh or at anchor. In addition, the vessel is configured for “re-provisioning” to other vessels for MGOs, hydraulic fluids, distillates, bio-fuels, lubricants, water, stores or groceries. The vessel may be configured for performing “midstream fueling,” provisioning of engineering equipment and supplying “stores” for other consumables when operating on inland waters. The present disclosure is susceptible to embodiments of different forms. There are shown in the drawings, and herein will be described in detail, specific embodiments of the present disclosure with the understanding that the present disclosure is to be considered an exemplification of the principles of the present disclosure and is not intended to limit the present disclosure to that illustrated and described herein.

A versatile transport-delivery vessel may be configured for operation on water to transport LNG and to deliver supplies as additional cargo. This additional cargo is not configured to be used or consumed by the transport-delivery vessel. The additional cargo is configured for at least one of: bunkering, re-provisioning, and midstream fueling of another vessel as would be understood by a person of ordinary skill in the art with the benefit of the present disclosure. The versatile transport-delivery vessel may include one or more LNG tanks and one or more additional tanks configured to carry the additional cargo. The cargo may be stored in one or more tanks or compartments. The one or more of the tanks may be integrated with the hull of the versatile transport-delivery vessel. One or more of the tanks may be separate from the hull. In some embodiments, the additional cargo may be resupply cargo. Herein, “resupply cargo” is cargo that is used for resupplying operational consumables in a lake, sound, bay, inland or ocean going vessel. For instance, resupply cargo may include, but is not limited to, one or more of MGO, hydraulic fluids, distillates, bio-fuels, lubricants, and water.

The versatile transport-delivery vessel may include a barge section and a tug section. Each of the two sections may be configured to mate with the other to form a locking connection. Other configurations, such as a self-propelled single vessel is also contemplated. In the tug barge configuration, the locking connection may be rigid (as in ITBs) or allow for some movement (as in ATBs or Push Boat & Barge or Tug and barge on tow line). The preferred embodiment is an ATB configuration. Both of the sections may be configured to comply with Det Norske Veritas (DNV) certification (or other classification societies) and Jones Act requirements for water vessels. Both of the sections may also be configured with a fully loaded draft that is compliant with inland waterway requirements. In some embodiments, the fully loaded draft of the sections is at or under 9 feet and 6 inches. The LNG transport-delivery vessel may be configured to comply with overall length, beam, and channel requirements for transit on US Inland Waterways (including, but not limited to, GIWW, Mississippi River, and Ohio River). The overall length and beam are configured for transit through lock structures, bridges, overhangs and channels along US Inland Waterways. The LNG transport-delivery vessel may have an aerial draft that is under the lowest aerial clearances for GIWW, Mississippi River, and Ohio River.

In some embodiments, the tanks 150 are integrated with the hull 115. The number of tanks 150 is shown as two, however, more than two tanks 150 may be included in barge 105. In some embodiments, a single tank 150 may be disposed on the barge 105. The additional cargo containment 160 may include one or more tanks or compartments. As shown here, the additional containment 160 may be integrated into the hull 115. In some embodiments, the containment 160 may include one or more of MGO, hydraulic fluids, distillates, bio-fuels, lubricants, and water. Here, the containment 160 includes a port MGO tank 163p, a starboard MGO tank 163s, a port fuel oil tank 165p, and a starboard fuel oil tank 165s. FIG. 6B shows a side view of barge 105 from FIG. 5. FIG. 6C shows a front view of barge 105 from FIG. 5.

FIG. 7 shows a cutaway view showing the starboard side of the barge 105. The starboard fuel oil tank 165s and the starboard MGO tank 163s are shown integrated in hull 115 below the level of the deck 117 near the recessed area 110. The location of the additional cargo compartments 160 near the second end 102 is exemplary and illustrative only, as the additional cargo compartments 160 may be located anywhere on or in the barge 105.

In operation, the additional cargo stored in the compartments 160 or non-integrated tanks 180 may be moved from the vessel 100, 400 to a second marine vessel. The additional cargo may be moved by pumping of the additional cargo (if pumpable) through umbilicals or hoses between the marine vessels, by crane offloading, or by manual offloading of the additional cargo as would be understood by a person of ordinary skill in the art.
