Benefits of technology

[0017]It is possible to arrange seating for passengers in an outside area, such as on deck, but preferably the supply vessel has a deckhouse arranged with seating for at least 5 passengers. The transfer to the off-shore facility may take place in rough weather, and then it is an advantage to seat the passengers sheltered within the deckhouse. For some offshore sites it is an advantage if the supply vessel can transfer more persons per voyage, so in a preferred embodiment the deckhouse is arranged with seating for at least 10 passengers.

Problems solved by technology

The considerable distance between the offshore facility and the shore results has as a result that it takes time to transfer perso

first embodiment

[0032]In the first embodiment the supply vessel has the following main particulars:

Length overall22.00 mBreadth12.00 mDepth to upper deck 4.50 mDraught (free sailing) 2.00 m

[0033]The deadweight at summer draught may be at about 35 t.

[0034]The supply vessel has two hull sections 8 interconnected by a deck structure 22 and a deckhouse 9. The deckhouse has a lower part 21 with a passenger main saloon provided with a plurality of passenger chairs, such as 12 chairs. Next to the saloon the deckhouse has a lavatory, and the saloon may be provided with galley corner with dishwasher and cooking facilities. In an upper part 20 the deckhouse is provided with a bridge having at least a forward 18 and an aft 17 maneuvering position with skipper chairs, echo sounder, vhf radios and radar or other navigational and safety equipment.

[0035]In the bow the supply vessel is provided with a fender 16 at the middle of the bow. The aft deck has a tug layout. A towing winch 11 is located just aft of the de...

second embodiment

[0043]In the second embodiment the supply vessel has the following main particulars:

Length overall23 mBreadth12 mDepth to upper deck4.50 mSpeedabove 20 knotsBollard pull25 tTowing winch30 tTugger winch3 tPassengers12Crew4Propulsion engines2 × 1100 hp

[0044]A propulsion engine 29 is arranged in each hull section 8, and via a propeller shaft 32 the propeller 31 is driven by the engine. The propeller may have adjustable pitch, and is located in a propeller nozzle 33. Each engine room is provided with ventilation air through air intakes 34 and 35. Each engine can deliver a power of 1100 hp.

[0045]The stern roller 10 located in a central location aft of the towing winch can be a fixed curved surface in the hull of the vessel, which curved surface allows the chains, wires or other equipment handled by the tugger winch and the towing winch to roll over and along the surface when entering or leaving the vessel. The stern roller can also be a circular cylindrical body mounted at the stern with...

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority based on Danish Patent Application No. PA 2012 70745 filed on Nov. 30, 2012, the contents of all of which are incorporated herein by reference in their entirety.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not Applicable.REFERENCE TO A MICROFICHE APPENDIX[0003]Not Applicable.BACKGROUND OF THE INVENTION[0004]The present invention relates to a supply vessel equipped with passenger seating for transferring service personnel to and from an off-shore facility, said supply vessel having a transfer speed of at least 16 knots.[0005]Supply vessels of this kind are used for transferring personnel from shore to an offshore facility, and from this facility back on shore. Some offshore facilities are unmanned and require service at intervals, such as three to four times per year. When repairs are to be performed, equipment needs to be sailed out to the offshore facility.[0006]Offshore facilities...
