Desmountable galvanized floor grating,anti-slip type bolted to metallic profiles
frame in correspondence of the pump room and of the side cofferdams.
Dripping-pans under each motor with drainage to the oily bilge tank.
Fuel and oily bilge tanks of structural type,with manholes,flanged
penetrations and dripping-pans with coaming shall be positioned in a raised
position to supply a slight positive head to the fuel feeding lines.
Pad eyes above all machineries for maintenance and debarkation.
Inside the pump room one shelving for storage and one working table with vice
shall be installed.
Ballast tanks equipped with sounding pipes of at least 2" diameter heading to a
recessed stainless steel/bronze terminal positioned on the deck at side.
Pipes schedule 80 for the pipes and for the penetrations (hot galvanized after
the prefabrication) with construction details such that the galvanization will
not be damaged by the installation.
Fuel tanks served by visual gauges of approved type by the Classification
Society for hydrocarbons.
Level gauges for ballast tanks shall be of capacitive type,with upper head in a
suitable box under the Main Deck,watertight,with bolted cover flush with the
deck.Electric wire from the box to the Pump Room shall be laid down inside a
metallic conduit,galvanized type and watertight.
Alternative type (air bubble) may be considered.
Oily bilge and sludge tank shall be arranged with sounding pipe in Pump Room
above grating with approved type valve and pedal for open/close.
Ballast manifolds shall be equipped with not immersed shut off valves
separating the system in three sections (port,centre and starboard) each one
separately connectable to the suction and delivery manifolds of each one of the
two pumps and to the sea chests.
