Utility Hoods.
Protect connection points or "utility risers" projecting above deck or bullrail from
snagging of mooring lines by pipe rails or concrete hoods, as shown in Figure 4-
8. Alternatively, when the bullrail is wide enough, employ hinged utility covers
like the one shown in Figure 4-3. For convenience of the users, the risers should
not face away from the ship, and should be adequately sized for ease of
operation.

Wearing Course.
Generally, a wearing course is not needed for concrete deck structure. However,
for precast concrete decks, an asphalt concrete or cement concrete wearing
surface may be utilized to provide a slope for drainage. For ballasted decks and
for solid (filled) type construction, a wearing course is necessary. For these
applications, asphaltic concrete is preferred over cement concrete as the former
is easier to repair and maintain and better tolerates substrate movement.
