The LCTC (Large Car and Truck Carrier) MV Tulane is designed for worldwide transportation of rolling cargoes, including cars, High & Heavy rolling cargoes on wheels and tracks (e.g. vehicles used in construction mining and agriculture) roll trailers and, to some extent, breakbulk cargoes (e.g. rubber in crates, steel coils, pipes).
The vessel is arranged with 13 decks for cargo, engine room aft, wheelhouse forward and living quarters in one tier on the upper deck. The mooring decks are arranged on deck 7. The cargo holds are constructed with one row of pillars in general, except for two pillars in the aft part, and a longitudinal pillar spacing of 10.80 m.
The vessel is constructed with two watertight decks (deck 5 and 8) and one gas tight deck (deck 10). Watertightness is ensured by the stern ramp. Watertight closing of deck 5 and 8 is by means of a hoistable ramp and covers.The ship’s rescue boat is arranged in a recess (a pocket) in the ship’s port side, on deck 8, for safe and fast lowering. The wheelhouse is totally enclosed with overhanging bridge wings for enhanced control.
The vessel is equipped with a fuel-saving Rolls-Royce Promas spade rudder integrated with the propeller by a propeller cap and rudder bulb.
Cargo Hold Arrangement & Capacity
Heavy cargo units can be loaded on deck 1, 3, 5 and 8. Deck 2, 4, 6, 7 and 9 are divided into liftable sections to accommodate a variable cargo mix efficiently. These deck panels are hoisted and lowered by two mobile deck lifters.
Cargo can be loaded and discharged over a wide and strong stern ramp.
Access to lower cargo holds by means of fixed ramps. Access to upper cargo holds by means of liftable ramps.
Tank Arrangement and Capacities
Water ballast can be carried in the double bottom, wing tanks forward and the forepeak and aftpeak tank. To improve stability, the ship carries fixed ballast in one double bottom centre tank.
The vessel is powered by one electronically controlled slow speed, two stroke main engine and propelled by a single fixed pitch (FP) propeller. All engines comply with IMO Tier II requirements to NOX emissions.
Main and auxiliary engines comply with reduced NOX emission limits stipulated by IMO Tier II. Major electricity consumers such as the main cooling sea water pump to be frequency controlled with energy saving system.
