VESSEL REVIEW | Hav Leiti – Multi-purpose cargo carrier with self-discharging and advanced monitoring systems

Royal T Shipyards in the Netherlands recently delivered a new dry cargo vessel ordered by Faroe Islands-based Navigare Shipping.

Hav Leiti is the first unit in a new series of four vessels designed and built by Royal T Shipyards for the same owner.

The newbuild has a steel hull, an LOA of 89.98 metres (295.2 feet), a beam of 15.45 metres (50.69 feet), a draught of 6.55 metres (21.5 feet), a depth of 8.81 metres (28.9 feet), a deadweight of 5,880, and a gross tonnage of 3,984.

Built for maximising bulk and project cargo loads

Royal T Shipyards said the series has been designed to maximise cargo capacity while minimising fuel consumption and emissions.

Particular attention was given to the optimisation of the cargo hold, which was specifically tailored to Navigare Shipping’s operational requirements. With a cargo hold capacity of approximately 278,000 cubic feet (7,870 cubic metres), the vessel will be capable of carrying a wide variety of bulk cargoes, aggregates and project cargoes while maximising cubic efficiency.

A key feature of the vessel is its electrically-powered self-discharging system. The integrated electric excavator allows efficient cargo handling while significantly reducing local emissions and noise levels during port operations.

Configured for low-emission operation

The ship is equipped with a diesel-electric propulsion system consisting of four 380kW generators that drive a nozzle-housed, fixed-pitch propeller to deliver a service speed of 10 knots. According to Royal T Shipyards, this configuration will provide excellent manoeuvrability, low fuel consumption, and a high degree of redundancy.

The propulsion concept will also support efficient operations throughout the vessel’s trading profile while ensuring compliance with IMO Tier III emission standards.

A 102kW generator is also available for emergency use. Diesel fuel is fed from tanks with a total capacity of 169 cubic metres (37,200 gallons). During port visits, particularly in Northern Europe, the ship will utilise a shore connection for electrical power, thus reducing reliance on the generators.

The vessel is fitted with a dedicated multi-input shore power transformer, specifically designed to accept various shore power configurations found in ports throughout Northern Europe. The builder said this will enable emission-free cargo operations whenever suitable shore power facilities are available.

Additional environmental measures include a sewage treatment plant suitable for environmentally sensitive operating areas, including the Baltic Sea region, and preparations for future alternative energy solutions.

Systems permitting remote monitoring from both onboard and onshore

The vessel’s electronics suite includes a complete alarm and control package supplied by Marble Automation. The installation covers tank readings, unattended machinery space (UMS) automation, and a ballast and bilge control system.

The UMS setup allows integration of additional third-party signals and equipment into the central alarm system. This gives the crew a clear and complete overview of all machinery spaces without needing to be physically present at all times.

The ballast and bilge control system, combined with the valve system, will handle automated management of water transfer and bilge operations. By connecting the pneumatic valve system directly into the Marble control setup, the operator gets full control from a single interface, reducing the need for manual intervention.

The alarm system also feeds into the onboard VDR, ensuring that all alarm and monitoring data is recorded continuously. Beyond the onboard systems, the setup is built to share data with remote monitoring parties such as ship managers, owners, or technical superintendents.

An emergency telegraph will meanwhile ensure direct and fast communication between the bridge and the engine room.

Hav Leiti has already commenced operations for Navigare Shipping. The remaining vessels in the series are currently under construction and will be delivered in 2026 and 2027. All are being built in compliance with Bureau Veritas class requirements.
