Chapter 5CHAPTER 5MACHINERY AND SYSTEMS1 Machinery and piping systems1.1 General1.1.1 Machinery and piping systems essential for the dockoperation are to be constructed and installed, as far asapplicable and practicable, in compliance with the requirementsof Part C, Ch 1 of the Rules.Arrangements to discharge ballast water are to be providedin such a way that at least two pumps may be used to draineach tank which may be flooded.2 Electrical installations2.1 General2.1.1 The components of the electrical installation are tobe constructed and installed in compliance with therequirements of Part C, Chapter 2 of the Rules.Parts constructed in compliance with national or internationalregulations for industrial installations will be speciallyconsidered.In this last case particular attention is to be given to theenvironmental conditions anticipated for the dock operations,and to the precautions taken for maintenance.2.1.2 The testing of the electrical installation is to includethe following phases:• inspection and test of components• check of the arrangement of components• final test of the installation.3 Documentation to be submitted3.1 General3.1.1 Documents and details relating to machinery andsystems required in Part C, Chapters 1 and 2, as far as reasonablyapplicable, are to be submitted to RINA forapproval.22 Rules for floating docks 2010
Chapter 6CHAPTER 6FIRE PROTECTION1 Application4 Fire extinction1.1 General1.1.1 As stated under [1.1.2] of Chapter 1, the requirementsof this Chapter 6 are not applicable for the purpose ofclassification, except where RINA carries out plan approvaland surveys relevant to fire protection statutory requirementson behalf of the flag Administration. In such cases,fire protection statutory requirements are considered a matterof class and therefore compliance with these requirementsis also verified by RINA for classification purposes.2 General2.1 Foreword2.1.1 The requirements for fire protection of the floatingdocks defined in this Chapter do not consider the liftedobjects.2.1.2 Equipment listed in [2.2] of Section 1 of RINA Rulesfor fire protection, detection and extinction for the issue andmaintenance of statutory certificates other than SOLAS certificatesis to be type approved by RINA.3 Structural fire protection and meansof escape3.1 Structures3.1.1 Caissons, pontoons, side walls, bulkheads, decksand deckhouses are to be made of one of the materials indicatedin [3] of Chapter 4. However, deckhouses, walls andinternal divisions may also be made of other suitable materialprovided that they are fitted, whenever necessary, withadequate fire insulation so that, in case of fire in suchspaces, the structure is prevented from collapsing. Alternativebut equivalent solutions will be specially considered byRINA.3.2 References3.2.1 The requirements of items [1.1.4] to [1.1.7], [1.3],[2.1.2], [2.1.3] and [2.2] of Section 3 of RINA Rules for fireprotection, detection and extinction for the issue of statutorycertificates other than SOLAS certificates are to beapplied.4.1 Water fire-fighting system (fire main)4.1.1 Generala) All docks are to be provided with fire pumps, piping,hydrants and hoses in compliance with the requirementscontained in this item [4.1].b) Docks with lifting capacity less than 200 t are to be providedwith at least one fixed hand pump.c) Docks with lifting capacity equal to 200 t or above butless than 1000 t are to be provided with at least onepump operated by mechanical energy and one handpump.d) Docks with lifting capacity equal to 1000 t or above butless than 2000 t are to be provided with not less thantwo independent pumps operated by mechanicalenergy, preferably arranged on each side of the dock.e) In addition, for docks with lifting capacity of 2000 t andabove, in case a fire in a compartment might put all thefire pumps out of service simultaneously, an independentemergency pump is to be provided.The capacity of the emergency pump will be determined ona case-by-case basis.The emergency pump is to have independent sea waterintake and connection to the fire main and is to be locatedin a promptly accessible area which is not likely to be cutoff by a fire in the area of the main pumps.A valve suitable for cutting off the connection between themain pumps and the fire main is to be fitted.Such valve is to be located in a promptly accessible positionoutside the main fire pump room.Where fire-fighting installations that may be used promptlyare available ashore, the emergency pump may not berequired.4.1.2 Hydrants, hoses and nozzlesa) One hose every 30 m of length of the dock is to be fittedon board; hoses are to be distributed along the docksides.In any case, not less than 6 hoses are to be fitted onboard docks with capacity equal to 1000 t or above andnot less than 4 hoses on board docks with smallercapacity.The hoses required for machinery and auxiliary boilerrooms are not included in the above-mentioned numbers.b) The number and location of hydrants are to be such thatat least two jets of water not coming from the samehydrant, one of which is from a single length of hoseRules for floating docks 2010 23
