CARGO VESSELS / WORKBOATS
Stern Landing Vessels
STS has developed, refined and proven a Stern Landing Vessel (SLV) design offering a superior alternative to conventional landing craft cargo vessel designs intended for coastal shipping operations.
Commercial applications for the SLV are similar to conventional landing craft; however the SLV design has overcome the primary problems associated with conventional landing craft, including:
- Poor head sea capability due to bluff bow ramp, dramatically reducing speed
- Poor visibility due to bow ramp
- Crew discomfort and fatigue due to location of accommodation directly above machinery spaces
- Inadequate power available when de-beaching due to propellers working inefficiently astern, and the need to overcome the forefoot suction effect
- Poor stability due to the low profile GZ curve, low freeboard and shallow deck edge immersion resulting in limited deadweight capacity
- Required ballast due to high block coefficient and poor stability
Incorporating a shallow ‘V’ hull with two side pods, off-centre shafts and a beaching protection aft skeg arrangement, the SLV is now a finely tuned design that has evolved into a commercially and operationally unbeatable landing craft design.

Pusher Tug / Barge (ATB)
World’s first STS quad screw catamaran tug, ideal for shallow winding rivers and open sea conditions. Tank tested in 2009 and proved 30% better than monohull tugs of the same power, pushing barges up to 15,000 DWT.
