The concept of this Deck Operating Manual is to provide information totechnicallycompetentshipsofficers,unfamiliartothevessel,inaformthatisreadilycomprehensible,thusaidingtheirunderstandingandknowledgeofthespecific vessel.Special attention is drawn to emergencyprocedures and firefightingsystems.
Themanual consists of a number of parts and sections which describe thesystems and equipment fitted and their method of operation related to aschematicdiagramwhereapplicable.
The valves and fittings identifications used in thismanual are usually thesameasthoseusedbytheshipbuilder.

The response of the ship may be different from the listed above if any of the followingconditions upon which the manoeuvring information was based are varied:
1) Calm weather: wind 10 knots or less, calm sea. 2) No current. 3) Water depth twice the vessel's draught or greater. 4) Clean hull. 5) Intermediate draughts or unusual trim.
At slow speed the transfer and advance is about the same as half speed, the speedsare proportionally less and the times proportionally greater.

Shutting down the System
a) Shutoffallindividualtanksteamandcondensatevalves.
b) Open drain valves to prevent a vacuum formingwhich coulddrawinoilthroughanypipedefects.
c) Close drain valves when the coils have reached ambienttemperature, in order to prevent ingress of sea water duringheavyweather.

b) Isolate thedefective tankheatingcoiland insertblanks in thesteaminletandcondensateoutletlines.
c) Proceedtoheatthetankusingtheothercoils.
Testing the Coils
The modern materials and the continuous welded construction used in theheating coils tend to offer reliable service. Routine testing by checking thecondensate outlet when putting the system into use will normally suffice.However, pinholes candevelop atwelds and loosepipebrackets can causefretting.
Ifcontaminationoccurs,testthedefectivecoilatthenextpossibleopportunity.This is carriedoutbyapplyinga freshwaterhydraulic testoncoilwith theoutletvalveclosed,enteringthetankwhenitisgasfreeandlocatingtheleak.
