Feeders are small to medium-sized container vessels that connect local ports with transshipment hubs so that containers can be loaded onto or distributed from deep-sea mainliner container vessels. They are also the workhorses for intra-regional trade, ensuring smooth trade flows within regions. Some feeder vessels are equipped with loading gear, making them less dependent on port infrastructure. The increasing adoption of global “hub-and-spoke” networks, where large vessels only call at major hubs, has created growing demand for feeders to ensure that cargoes reach their final destinations.

Crude oil tankers transport large quantities of crude oil and dirty oil products worldwide between global production hubs and consumption hubs. More specifically, these vessels are typically employed on medium- to long-haul routes and transport crude oil from oil fields and rigs to refineries for processing. All crude tankers have double hulls to reduce the risk of oil spills and to deliver a safe and efficient transport service to support the global energy networks. Crude tankers are among the largest vessels across all commercial shipping segments. Vessel types vary from smaller Panamaxes and Aframaxes to Suezmax tankers. The largest VLCCs (very large crude carriers) can carry up to 300,000 tonnes of oil.

LNG carriers transport liquified natural gas between exporting hubs to consumption areas with regasification capacity. LNG is widely used in numerous industries, for domestic heating and in power plants producing electricity. It is the preferred bridge solution for the energy transition and plays a vital role in energy security. In order to transport natural gas in liquid form in LNG carriers, it needs to be cooled to -163 degrees Celsius, at which point it liquifies and decreases in volume by 1/600th. LNG carriers are highly specialised vessels with membrane cargo containment systems that can maintain ultra-low temperatures during transit.

Offshore wind service operation vessels (“SOV”) ensure cost-effective maintenance and operation of wind farms. These sophisticated vessels are equipped with DP2, a dynamic positioning system, enabling them to remain in exactly the same position constantly irrespective of the wind and sea conditions during operations. The vessels can accommodate more than 40 service technicians in single outside cabins for up to two to three weeks with comfortable living conditions. The technicians can safely transfer to work on the turbine towers via state-of-the-art motion compensated gangways. The vessels also have state-of-the-art anti-roll systems to negate motion sickness for personnel, as well as battery hybrid propulsion and, increasingly, shore power connection.

Short sea RoRo (roll-on/roll-off) vessels are specialised vessels designed for the efficient transportation of wheeled cargoes, such as cars, trucks and trailers, which can be driven directly onto and off the vessels' decks, hence the name roll-on/roll-off. Their carry capacity is measured in lane metres (LM), representing the length of lanes available on the deck for vehicles. These vessels operate primarily on regional routes with a highly diverse mix of freight. Short-sea RoRo vessels play a crucial role in regional economies and are often viewed as part of the regional infrastructure. The efficiency and versatility of these vessels make them a vital component in intermodal transportation and an environmentally friendlier alternative to land-based transport, especially over longer distances.
