(3) If the protrusion exceeds the maximum allowed, each case is to be studied separately and

Art. 27 - Ballast Water:

Vessels in ballast must fill spaces intended to be used for carrying ballast water in such

Art. 28 - Searchlights:

Before transiting the Canal, the vessel should be provided with a searchlight (projector)
complying with the following conditions and specifications:

(1) It should be placed on the bow in the axis of the vessel and show the Canal clearly.
(2) Specifications are as follows:
a) Minimum range of radiation of single beam 1800 m. ahead (Brightness of 1 LUX

approx, at the atmospheric transmission factor T = 0.85).
b) The power of the lamp must give a luminous intensity of single light beam not less than

3 x 10 (3 million) candles, which is equivalent to a high efficiency incandescent lamp
of:

1 - 2000 watt for vessels up to 30000 SC.G.T.
2 - 3000 watt or a halogen lamp of 2000 watt for vessels over 30000 SC.G.T.
3 - Or any kind of lamps which that fulfills the specifications, under item (2) above and

to be of the non-explosive type.
c) The drum and stand should be of high corrosion resisting material and can be operated

both horizontally and vertically.
d) The front glass must be of hardened type and can stand rapid cooling.

e) The reflector must be in two halves of precise ground glass mirror of highest quality or
of polished aluminum having at least 95% the reflective capacity of the glass mirror.
f) The two halves of the reflector can be brought together (zero position) to make a single

reflector light beam and can be parted to give two separate light beams each of 5 degree
at least on the horizontal level with adjustable dark sector from 0 to 10 degree.

g) The searchlight drum must be watertight (pressure test 0.25kg/cm), with degree of
protection IP55.

h) Gastight searchlight (according to the classification rules) for the vessel’s having
electric appliances within the dangerous area , and provided with a vent out of which a

1 ) Containers on Containerships are not considered as deck cargo.
2 ) Specially built vessels and barges carrying drillers or bulky deck cargo to be studied each separately. (see item
