Transport Trimarans "Transtrims"
 

As is known, the nautical term "trimaran" as a rule means a sports vessel, which has two floats attached to its sides to make it more stable on water. The design of the offered "transport trimaran" radically differs from the early known constructions. Instead of side floats are placed the side hulls of an appropriate displacement tonnage, equipped with high-capacity marine engines.

From this moment the nautical term "transport vessel - trimaran" implies a principally new sea transport vessel, navigation features of which have changed as follows: the vessel becomes practically unsinkable; buoyancy, maneuverability, controllability and course-keeping qualities of the vessel at wide speed range are improved; the vessel is able to slew practically on a spot; inertial distance is reduced etc. For centuries people have been considering vessel just as a ship, which can transport cargo or passengers on condition that its bottom is waterproof. If its bottom is not hermetic, the incoming water will sink the ship. The design of the transport trimaran - transtrim radically broadens our past conception of a vessel and its capabilities.

These are the trimarans able to load and unload sole loaded floatation systems weighing many thousand tons - barcons, using locking method and through the opening fore and stern hold leaves, through the opening bottom leaves of the hold. The constructions have been worked out, where the transtrim's central transport hull is detached and placed for unloading, and the so-formed "temporary" catamaran at the near-by quay is connected to a similar already loaded hull, and then the trimaran departs to a port of destination.

Another design presents a trimaran, the middle transport hull of which is made of two separate parts. The smaller part with the engine is connected with the side hulls. And the bigger part is the transport hull, which is attached to the smaller part. There will be various designs of the detachable middle hull. But all of these designs will provide an opportunity to perform loading and unloading all along the area of the upper deck, but not through deck hatches as in existing constructions of ships (i.e. the deck will be a removable or a sliding etc.). So becomes possible simultaneous and parallel work of optimum handling machinery over the open sections of the trimaran transport hull. At the same time there will be an opportunity for building all types of containers for various purposes (to fit design of the transport hull). The barcons of every type will allow reducing of handling operations to one-step stowage of a barcon inside the vessel.

Transport trimarans - "transtrims" - will fundamentally change structure of seaports. The territory of seaports will be considerably reduced, since the need in cargo transhipment will decrease sharply. Most of cargo will be unloaded directly off the wheels (of motor vehicle or railway transport) into the barcons and detachable hulls of the transtrims moored at a quay. All this will have a beneficial effect on the competitiveness of sea cargo transportation.

Applying inter-hull hydrofoils in the transport trimarans will allow adjusting the draught of the vessel, and will add to its ability to pass through shallow water and earlier inaccessible sea canals. Transport trimarans of "river" and "river-sea" type have good prospects in reviving inland water transportation. The destruction of the shoreline with the waves formed by the ship hull and screw propeller is one of the main problems impeding the growth of speed of river transportation. Applying the river transport trimarans solves this problem, since the obtained engineering solutions solve it. And the detachable transport hull or its part saves the vessel from idle time.

As it is seen from the above-stated, the sea cargo transportation by transport trimarans will become more profitable compared with the cargo transportation by ordinary ships. In case of intensive construction of transport trimarans, sea transport will successfully compete with other types of transport in the 21st century.
