Floating Harbour Transhipper

Transhipping safely & efficiently

SEATRANSPORT'S logistics has a successful track record in dust-free transshipment vessels has focused on a total weather and environmental solution for the 21st century. Traditionally for bulk shipment, large storage sheds had to be built on prime waterfront land areas equal to the capacity of an export vessel. Then large expensive jetties would be built out to deep water, these jetties are also expensive to remove at the end of the mine’s life.

Most transhipment methods are generally restricted to sheltered in-shore or coastal waters, but dust and moisture limits are common problems. Additionally, most transhipment methods are restricted to a maximum wind speed of around 20 to 25 knots, are also restricted to wave heights 2 to 2.m and are limited by the size of their feeder vessels, the current wind and wave conditions.

SEATRANSPORT have focused on small harbour solutions with shallow draught feeder vessels. Designed for shallow harbours, we used quad screw stern landing vessels (SLVs). In this video we illustrate the operation and capabilities of SEATRANSPORT'S floating harbour transhiper – a compelling operational and environmental solution for the 21st century.

Stern Landing Vessel vs
conventional Landing Craft

In this video we explain the benefits of utilising a Stern Landing Vessel (or SLV) for heavy lifts in remove areas and unprepared beaches in comparison to Conventional Landing Craft (CLC) vessels.
  • CLC vessels have poor head sea capability. With an SLV the shape of the ship’s bow is designed to withstand large seas.
  • SLVs have a greater profile of the GZ curve.
  • SLVs have a greater range of visibility from within the wheelhouse.
  • When beaching, the hull of a CLC is effected by the shore’s suction effect which then leaves the propellers to work inefficiently in reverse in order to debeach. With an SLV the stern gear is completely protected from the shore’s suction effect allowing it to beach and debeach with ease.
  • The accommodation space of an SLV is completely separated from machinery space – unlike CLCs which often have machinery below the wheelhouse.
  • SLVs have no ballast, allowing them easier propulsion and handling.
  • SLVs have a finer hull shape with a higher sustainable speed.
  • SLVs have cargo deck spray protection.
  • SLVs allow access to bottom plating when beached.

LOCATION: Queensland, Australia
VESSEL TYPE: Transhipper

In this video we explore Northern Queensland’s Century Zinc Mine alongside the 110m Bulk Transhipper, the MV WUNMA.

This transhipment vessel was designed to move heavy materials – this particular vessel tasked with the exportation of lead zinc concentrate by transferring its cargo from the min to handymax ships located 10nm offshore.

The MV WUNMA has an overall length of 110m, a breadth of 21m and a depth of 7.8m with a cruising speed of 10 knots.

MV SeaLink


In this video we explore Fresh Creek in the Bahamas along with SEATRANSPORT'S MV SeaLink ferry.

The SeaLink ferry design was built to manoeuvre easily and quickly in shallow waters while carrying up to 32 vehicles and 250 passengers. With a cruising speed of 18 knots, the SeaLink is an efficient way to travel to any Bahamian destination.
