Sea freight, also known as ocean freight, is one of the longest established forms of transporting goods internationally. It’s also one of the most economical. While air freight is favoured for time-sensitive shipments, sea freight is still the first choice for many businesses and individuals looking for a cost-effective solution.

Sea freight services were revolutionised by the introduction of containerisation after the Second World War—loading ships with standardised containers allowed a greater volume of cargo per vessel and removed the need for warehousing.Today, the majority of sea cargo is transported in either TEU (twenty foot equivalent unit) or FEU (forty foot equivalent unit) containers.
