Dry Bulk Vessels

Dry bulk carriers are designed to transport non-liquid bulk cargo. They are responsible for transporting raw materials around the world. They have open cargo holds and are usually equipped with specialist cargo handling equipment.

Tanker Vessels

Tanker ships are designed to transport liquid cargo. They have multiple compartments to carry different liquids simultaneously and are constructed so they don’t cross-contaminate. They are responsible for delivering necessary supplies of essential products globally including oil and chemicals.

Container Vessels

Container ships are designed to transport standardised cargo containers. The containers are stacked onto the ships and carried to ports worldwide. These ships are categorised by their capacity which can range up to 20,000 TEUs (twenty-foot equivalent units). These ships have revolutionised the way goods are transported by sea and are easily transported to trucks or trains.

Breakbulk Vessels

Breakbulk vessels are vessels in which transport cargo or goods that cannot fit inside regular cargo bins. They are usually transported in bags, boxes, crates, barrels or palettes. These vessels are usually Ro-Ro vessels or Lo-Lo vessels.

Heavy Life/Project Cargo Vessels

Heavy Life vessels transport goods or equipment that are tedious to break down or are oversized. The vessels are equipped with the cranes and necessary equipment to load and unload these goods. Best vessels to transport these goods are Multi-Purpose or Heavy-Life vessels.

Offshore Vessels

Offshore vessels are specifically designed for serving operational purposes such as oil exploration and construction. These vessels can also provide necessary supplies to the evacuation and construction units that are located at sea as well as the movement of crewing personnel to and from the operational areas.
