1.1. Insulation of Marine Piping and Equipment

Sea Water SystemsThe pipes on main deck shall be insulated against freezing.

Sanitary and Utility WaterCold water

In order to avoid freezing of the safety shower and eye bath water supply pipe on upperdeck, where water does not circulate continuously through the pipes, electrical heat tracingshall be used.For water supply, at all times of the safety shower and eye bah on upper deck,which does not circulating continuously through the pipes and avoid freezing is used electricheat tracing. For Pp ipes located in the Engine Room and Accommodation do not require insulation, it isnot required to be insulated, ambient temperature is 5-45C and 20-24C.

Hot waterFor Tt he system of hot water supply , have water is circulating continuously through thepipes to maintain a minimum temperature of 60C , consequently, personnel protectioninsulation shall be used. and is used for insulated personnel protection .

Deck washIn weather conditions where freezing may occur, the system is supplied with drain valvefitted at the lowest point, where water could be completely drained.

Water coolingWater cooling system is arranged both on upper deck and in the engine room. Water cooling

pipes on upper deck shall be insulated against freezing. For The pipes that are inside theEngine Room, no heat tracing or freezing and insulation is foreseen required as ambienttemperature is over the freezing limit . The ambient temperature inside E.R being over thefreezing limit and pipes on upper deck will be insulated.

Compressed Air, Tank Vent and SoundingThese pipes Normally these pipes do not normally come into contact with liquid, either insideor outside, so insulation is not required. and it is not necessary to be insulated these pipes .

Steam, Boiler & Exhaust Gas SystemInsulation must be fitted around steam piping to lower surface temperature below 50C, tor educe the risk of fire in machinery spaces.

Washing Water TankThe operating temperature for washing water is 40-65C, and after washing the tanks thepipe will be is empt yied .

FIRE FIGHTINGThe fire fightingfirefighting take-of f branches of ND 3" to 8" should be heat loss protectedwith insulation for pipes below 3" insulation and electrical heat tracing (anti-ex for zone 1, ii

b/t3) shall be provided.The pipes on deluge valve skid outlet are normally empty and no freezing protection isrequired

Open Drain SystemRequirements for insulation and heat tracing of open drain lines are not foreseen, as theopen drain lines will be self drainedself-drained . However, heat-tracing insulation should beprovided if the effects of freezing are identified as being critical. Liquid seals can freeze andblock drainage. Heat tracing and insulation of liquid seals will be required if constant flowcannot be achieved.
