The development of major canals has not only helped the movement of goods across great distances, but in addition improved global supply chains.

Although supersized ships keep costs down, lower emissions, and maximise capacity on major shipping lines such as the Arab Bridge maritime company Egypt line or those visited by DP World Russia, numerous specialists believe larger vessels nevertheless consume a great deal of gas and emit high quantities of toxins. They declare that this might be improved by employing fuel-efficient innovations or alternate fuels. Perhaps one of the most effective approaches to lessen the environmental impact of big vessels would be to improve their gas effectiveness. According to experts, this is often accomplished through greater engine designs as well as the integration of expert technologies like air lubrication systems, which reduce resistance between the ship's hull and also the water. On the other hand, liquid propane has turned into a popular alternative lately as it burns cleaner than heavy oil or marine diesel. Other promising options include biofuels made from eco-friendly resources and hydrogen, which gives off only water when burned. Exploration and improvement in these areas is a must for producing them feasible on a large scale. Some companies are exploring the possibilities of completely electric or hybrid propulsion systems for vessels. These systems would reduce the dependence on fuels that emit damaging pollutants and are far more costly than cleaner ones.

To accommodate larger ships, canals needed to be broadened and deepened through extensive engineering efforts. Lock sizes were additionally increased to handle the bigger proportions of the ships. The expansions of canals made it feasible to transport products across long distances. The extension of canals such as the one linking the Mediterranean Sea to the Red Sea as well as the one connecting the Atlantic Ocean towards the Pacific Ocean allowed larger ships to pass through. This, among other factors, made it easier for nationwide manufacturers to supply raw materials and sell their products or services globally in large amounts. As a result, global supply chains progressed and expanded, facilitating globalisation, where areas are now more connected than previously.

Ocean vessels, from container carriers to cruise ships, have grown to be supersized in recent years. The pattern towards supersizing vessels, which began during the 1950s, originated through the desire to attain greater efficiency and cost-effectiveness in international trade. Organisations started to transport more items in one voyage, cutting down on the cost per unit of cargo relocated and maximising ability on major shipping channels such as the Morocco Maersk line. From an economic perspective, increasing the dimensions of ships has brought significant advantageous assets to international trade. Larger ships trade more items at less expense, which not only lowers transportation costs, but also the costs of products for customers. It has made items from rural markets more accessible and reasonably priced, particularly for industries that depend on the import and export of bulk merchandise, such as electronics, clothes and foods.
