American Patriot Bulk Transport LLC offers shippers the most cost efficient and “Green” ocean bulk transportation available in the market place. A patented features on the vessel is the wave piercing bow structure that reduces fuel consumption approximately 20% from conventional ship hull designs. Additionally, the deckhouse is designed to perform the function of a sail by reducing air resistance in head wind and increasing it in following wind. CFD simulation on the deck house shows the difference in power consumption between this innovative design and a conventional house to be 800 kW on average in 25 knot steady wind. Ocean ATB Bulk Vessel
In October 2015, American Patriot Bulk Transport LLC (APBT), conducted model testing in Potsdam Germany of the ATB Hull Form created by Naviform Consulting and Research Ltd.
The ATB design, owned by American Patriot Holdings LLC (APH), is planned to be built as a dry bulk carrier utilizing the tug design and the barge hull form modified for dry bulk cargoes and self-unloading equipment with cargo capacity between 40,000 - 50,000 DWT, depending on charterers final requirements.
The vessel will be dual fuel (LNG and MGO) and capable of underway transit speeds greater than 13 knots in a sea state up to 5. The planned design includes a diesel electric plant consisting of four (4) Diesel generators (2880 KW ea.) driving two (2) main azimuthing drives and a bow pump, allowing the vessel to safely dock and un-dock under its own power without the need for assist tugs.
The design has a patented bow structure which contributes to the vessels speed by dampening pitch, and significantly dampens the relative motion between the barge and the tug. The relative motion reduction of more than 50% is a major benefit in reducing crew fatigue.
The vessel will be geared with discharge capacity from the latest technology in self-unloading equipment with a minimum discharge capacity of up to 5,000 MT per hour. The design also includes built in washing capacity to facilitate cargo changes.
This State of the Art hull design is expected to service existing customers relying on efficient transportation of fertilizer, coal and pet coke, as well as new customers with significant demand for solid fuel transportation commencing in early 2021.
