Field of Invention
The present invention relates to stowage arrangement for fixed shore beams used
onboard vessels. More particularly, the present invention is an improved arrangement in
locking and arresting the shoring beams preventing any flooding from door & hatch.
Background Art
The shoring beams were secured vertically, as shown in Fig. 1 and Fig.2, on-board
during the trials, using the simple groove system. During its trials in rough seas, due to the
heaving motion & pounding of the vessel, a few locking plates of the stowages turned open,
letting the shoring beam to topple down on the deck.
When an alternate solution of securing the locking plate on either sides using nuts &
bolts were implemented, the NBCD school submitted an objection, reasoning that during
emergency, the sailor may need spanners to release the shoring beams.
(a) Vertical securing, as shown in Fig. 1, while released, usually drops on the
deck, with a thump, usually damaging the deck gradually. Horizontal stowage
stays in position, unless heavy rolling or heaving, even after releasing the
securing.
(b) Lifting & shifting the shoring beam from the deck takes more effort than
lifting it directly from a raised stowage arrangement.

Drawbacks of the Existing Design
1. With the groove system, the securing arrangement opens up during rough
seas & pounding.
2. With the double side bolting system, it takes spanners & more time to release
the shoring beams.
3. While stowed vertically, it takes more strain to shift it for locking.
Object of Invention
To construct a design (of stowage for shoring beams) which takes less strain for
arresting during emergency & to have a robust securing method to prevent toppling of the
shoring beams during rough seas & pounding.
Summary of invention
Therefore such as herein described there is provided a stowage arrangement for
shoring beams comprising of a doubler plate; two Locking plates including hole and bell-
curve groove on opposite ends; angles with a plurality of bolt, nuts, butterfly nut and
washer; two Locking plates on either sides of the shoring beams, with said plates on the
inner edge of the said plates; wherein the said locking plate's goove side to be fastened with
a butterfly nut over a bolt welded to the angle; wherein the said locking plate's hole side to
be fixed to the angle with bolt & nut, and the goove side to be fastened with a butterfly nut
over a bolt welded to the angle with horizontal stowage of the shoring beams.

Detailed Description
As shown in Fig.3 and Fig.4, the fixed Shoring beams are used onboard vessels to
lock & arrest flooding from door & hatch. The shoring beams are to be stowed close to the
respective hatch/door. The beams are to be accessed readily for arresting a hatch or door
with potential chances of flooding. The stowage arrangement for shoring beams, uses a flat
bar with a bell curve-groove & butterfly nut for securing the shoring beam in horizontal
alignment.

On either sides of the shoring beam, on the inner edge of the rods, the angle, locking
plate arrangement is fixed. It is a swing type locking plate, swing around the bolted point.
The locking plate is swung closed to fix over the welded bolt & fastened with the butterfly
nut & washer.
While releasing the shoring beam, the butterfly nut on the either sides are turned to
loosen & the locking plate is swung open. Shoring beam can be lifted by holding the rod
hooks. Further, in the horizontal securing as shown in Fig.5, wherein the free space on the
bulkhead, at heights more than a metre from the deck, can also be used for stowage. Thus,
utilizing the area more optimally.
1. The shoring beam is stowed horizontally.
2. Four nos. of doublers & angles of appropriate sizes (65 x 65 x 5 - 50mm
wide) are fixed in the arrangement as shown in the figure.
3. The angles are placed on the inner sides of the shoring beam rods, so as to
arrest the movement on the shoring beam while secured.
4. A locking plate, made out of a flat bar, is cut with a bell curve groove on one
end & a hole for bolts on the other end.
5. The hole side is fixed with a SS nut & bolt where the tail end of the bolt is tack
welded to arrest the nut from slipping out.
6. On the groove cut side, the bolt head is welded to the angle, while the bolt
protrudes outside the locking plate.
7. A butterfly nut with washer is used on the tail end, with a tack weld on the tail
end to arrest the nut from slipping out.

8. The bell curve groove will be placed on the bolt & tightened with the butterfly
nut.

The concept, design and method of fabrication & fitment of stowage arrangement of
shoring beams in the said work resulting in simplification work, and increased safety. The
invention can be applied on both naval ship and merchant vessel construction.
Advantages and Uses of Invention
(a) The motion of the shoring beams are arrested completely during rough seas
& pounding.

(b) Removal of the shoring beam for emergency execution takes lesser time &
lesser strain.
(c) No tools such as spanners are required for releasing the shoring beams. It can
be released with bare hands.
(d) Unlike the vertical stowage design, shoring beams can be stowed one above
the other with a minimum spacing.
