Abstract
A sea going vessel, particularly adapted to serve as a supply and servicing ship for off-shore drilling platforms by fulfilling towing, anchor handling, and cargo carrying functions, wherein the propulsion and steering equipment is positioned in the forward portion of the vessel, a keel fin is provided underneath the aft portion of the hull, the deck house is located at a substantial distance aft from both the bow and the steering and propulsion equipment, the towing and anchor handling equipment is located aft of the deck house, and the cargo carrying space is located forward of the deckhouse.
Claims3
A sea going vessel, particularly adapted to serve as a supply and servicing vessel for off-shore drilling platforms through the capability of fulfilling with one ship towing, anchor handling, and load carrying functions, comprising:
- an underlying hull structure,
- propulsion and steering means which are positioned in and underneath the forward portion of the hull structure,
- a keel fin positioned underneath the aft portion of the hull structure,
- towing means positioned on the aft portion of the hull structure,
- the relative positioning of propulsion and steering means, keel fin, and towing means provide enhanced maneuverability of the vessel and its towed load,
- a deck house with bridge positioned in the aft portion of the vessel forward of the towing means and at a substantial distance abaft the bow and the propulsion and steering means, the positioning of said deck house providing improved protection from the seas impinging upon the bow and improved visual surveillance of all exposed decks of the vessels,
- cargo carrying space positioned forward of the deck house and the towing means thereby avoiding interference between the cargo and the aft running towing cable, said cargo carrying space extending a substantial distance forward of the deck house in proportion to the length of the vessel, said cargo-carrying space comprising a weather deck wherein said weather deck is positioned at a greater elevation above the water line than the elevation of the towing means, said difference in elevation providing improved protection from the seas of the cargo loaded atop the weather deck while enhancing maneuverability by locating the towing means closer to the water line.
