Stern Landing Vessels
•Sea Transports Solutions Stern Landing Vessels (S.L.V.) have
carved a niche into the small ship market, opening significant
opportunities for builders and operators of passenger, utility,
container, roro, bulk, AHTS and PSV vessels.
•The S.L.V. was a result of Sea Transport Solutions focussing on
possible answers to the operational problems of conventional
landing craft and to produce a vessel suitable for multi purposes.
Conventional Landing Craft
Problem Area No. 1:-
Poor Head Sea Capability
•Having a bluff bow , waves in excess of 600mm
(2 feet) start to cause slamming, jarring of the
whole structure and spray enshrouding the cargo
and the wheelhouse…….,
and the speed will drop dramatically
Conventional Landing Craft
Problem Area No. 2:-
Poor Visibility
• The bow ramp in the stowed position creates a blind sector in
the wheelhouse visibility. As most of these craft operate in
coastal, inland and shallow areas, this of course is a problem in
close quarter navigation. There are many recorded instances of
groundings due to this fact, and running into windsurfers &
small fishing boats at anchor has also occurred.
Conventional Landing Craft
Problem Area No. 3:-
Wheelhouse on top of Machinery
• The machinery space below the wheelhouse is just a source of
noise and vibrations which makes life unpleasant for those
onboard. For the crew, this can lead to lack of concentration and
fatigue, particularly on extended voyages.
Conventional Landing Craft
Problem Area No. 4:-
Beaching and Debeaching
• While trying to debeach, the traditional landing barge
frequently encounters difficulty, particularly where the
bow has grounded. This encompasses:1. Propellers working inefficiently (ie. in reverse).
2. Problematic loading of heavy equipment & large trucks.
3. Bottom suction to sea bed in low draft, soft soil areas.
Conventional Landing Craft
Problem Area No. 5:-
Lack of Deadweight
• The stability of a box shape barge is quite limited due to:
1. Low profile of the GZ curve.
2. Small freeboard, & shallow deck edge immersion 4-5degrees.
3. Free surface of numerous below deck flat bottom tanks.
• The stated total deadweight (dwt) of these vessels in most cases includes
below deck liquid cargoes.
“On deck” dwt is frequently as low as 45% of the total dwt.
Conventional Landing Craft
Problem Area No. 6:Loss of Ramp
• Constant pounding of the bow ramp may
loosen securing fixtures and drop the ramp.
• Once the ramp submerges with the vessel
underway the forces generated will fold the
ramp under the vessel and tear it off.

THE
S O L U T I O N ???
• In 1984, S T S established the criteria for an SLV.
1. Good head sea capability.
2. Ability to beach & debeach with ease.
3. Good visibility from the wheelhouse.
4. Accommodation clear of machinery space
5. Finer hull shape with a higher sustainable speed.
6. Cargo deck spray protection
7. Less free surface in tanks.
8. Access to bottom plating when beached
9. Elimination of the suction effect
10. Total protection of the stern gear
The Solutions is
the
Stern Landing Vessel
The S.L.V. incorporates a shallow “V” hull with two side pods, offcentre
shafts & a beaching/protection/aft skeg arrangement.
• The Stern Landing Vessel is now a fine tuned design that has evolved to
be a commercially & operationally unbeatable landing craft design
suitable for multi purposes.
