Abstract: According to the regulations, the fixed water mist fire extinguishing type can be used in the class A machine room and the cabin of the ship, but most of the existing ships are scattered to set up their own separate systems, resulting in many problems such as multi-equipment configuration, complex management, heavy maintenance workload and high cost. This paper briefly introduces the high-pressure water mist fire extinguishing integrated system of a drilling amp; production ship, which can provide protection for multiple areas and simplify the configuration of fixed fire protection system for the entire ship with good environment, in order to promote its application in the field of ships.
Key words: high-pressure water mist fire extinguishing system;" integration; control principle;" fire fighting
1" " "引言
大洋深水鉆采船舶作為一個特殊作業(yè)船舶,相較于普通的鉆井平臺具有機動性好、遠航能力強等優(yōu)點。但鉆采船空間有限,設(shè)備艙室、人員居住處所、實驗室、公共處所繁多。在選擇固定式滅火系統(tǒng)時,需要滿足SOLAS公約或相關(guān)法規(guī)要求,同時與實際條件相匹配。據(jù)分析對比,如船舶A類機器處、住艙等處所集成采用固定式水霧滅火系統(tǒng),可以節(jié)省材料,簡化系統(tǒng)布置,降低后期維護成本[1],且水霧釋放對大氣環(huán)境不會造成污染。
某鉆采船總噸位33 000 t,船長180 m,使用全回轉(zhuǎn)電力驅(qū)動,設(shè)有DP3動力定位,配員180人。該船配置一套高壓水霧滅火集成系統(tǒng),供全船人員居住處所、公共場所、A類機器處所及其他機器處所滅火。下面簡要介紹其系統(tǒng)組成,工作原理和各區(qū)域系統(tǒng)設(shè)計布置與控制原理及其優(yōu)化設(shè)計。
2" " "系統(tǒng)組成
高壓水霧系統(tǒng)主要由水源、高壓泵組單元、儲能單元、區(qū)域釋放閥、噴嘴、控制系統(tǒng)與聲光報警系統(tǒng)組成。
