       RESTRICTIONS TO THE EFFICIENCY OF HANDLING                                                  CONTAINERS


In 2013 the first of a new fleet of the world’s largest container ships, the “triple E”, completed its first voyage carrying an estimated 18,000 teu.

In 2021 there are many container ships afloat and on order which carry 24,000 teu.  But these are never filled with fully loaded containers.  The maximum has proven to be closer to 20,000 teu.

The economies of carrying this quantity of containers in one ship are apparent but must have to be counter balanced by multiple adverse factors :


Port access -insufficient draught

Port congestion

Canal and river access restricted

Dock size and facilities require costly expansion

Quantity and size of dockside cranes

Accessibility to any one selected container mis-loaded

Flexibility of different cargos

Time - double/treble handling and cost of loading and unloading




Loaded shipping containers are transported from the source of the cargo by sea

or by road to the Technomax docks, which are built at 90 deg to the shoreline

with several straddle cranes serving each dock. So trucks and trains will

line up parallel to the barge.  This layout also facilitates unloading from a barge

onto a train or onto a truck or onto the land to await transfer or storage.


Standard containers, full or empty, are loaded into a barge – basically a large empty steel box  of  c. 40,000 cubic metres - by straddle cranes at the  Technomax docks. 

The barges, which are autonomous, self-powered and fitted with ballast tanks, are driven into a semi-submersible Technomax ship,  which can be anchored a distance away in deeper water or off-shore. 

Barges are powered by re-chargeable electric cells.

The barges are floated in through the stern doors of the unique semi-submersible

Technomax ship, which has patented design features : the hull’s cribbing

matching that on the barge and the locking mechanism securing the barges

to the hull..

A barge is totally versatile because it can be designed to hold an almost unlimited range of types of cargos or of bulk goods, vehicles, pleasure boats etc


There are many options for the barge size – the most used are :-


Barge #B   360 teu            Barge #D   720 teu


The  #1 Technomax ship is 950 ft LOA -100 ft beam  

               8 x #B  = 2,880 teu  or  4 x #D = 2,880 teu

The  #2  Technomax ship is 1,190 ft LOA  - 160 ft beam

              20 x #B  = 7,200 teu  or  10 x #D = 7,200 teu

The  #3 Technomax ship is 1,430 ft LOA – 250 ft beam

              36 x #B  = 12,960 teu  or  18 x #D =  12,960 teu


The #1 Technomax ship - 2,880 teu  can navigate the old Panama Cana

The #2 Technomax ship - 7,200 teu   can navigate the new Panama Canal

The #3 Technomax ship – 12,960 teu  can navigate the Suez canal


These Technomax ships can navigate across every ocean.


A Technomax ship can carry a mix of barge sizes depending on their

overall weight and on their destination ports.


The operation of Technomax ships is close to carbon zero

and will contribute to meeting the IMO emission targets & regulations

  • powered by one or more alternative fuels, such as LNG or hydrogen

  • augmented by solar panels fitted on the top deck

  • wind power from Flettner rotary sails


Technomax ships will be data driven - fully equipped with all the latest

digital systems to monitor power (and crew) and to control navigation,

to ensure JIT arrival at each destination.

Each ship will be constructed with technologically advanced materials.


The Technomax ships can cross the ocean possibly faster than existing

container ships. Their annual days usage is greater because

a Technomax ship will not be moored at each port for several days.


At one or more destinations the ship will semi-submerse to float out some

or all the barges, which will motor to one or more ports.

If necessary, a barge can be used as for temporary floating storage

at the source port or at a destination port, saving land space.

Once emptied, the ship can float-in loaded barges. which are

waiting off-shore,  and set sail again within an hour or so of arrival

and set sail to another port or return to the port of origin.
