requirements with relevant appropriate references to various international codes and standards which are. applicable to the design and installation of offshore service modules. Offshore service modules are designed to perform temporary services on offshore installations and may be. placed on different offshore installations and units in different national waters. This standard for certification applies basic requirements from other DNV GL rules and standards to offshore. service modules and has been based primarily on recognised practices for the offshore industry It is. intended that the standard will be suitable for global usage It should however be noted that some shelf. or flag states may have stricter or other requirements than those given in this standard. Modules designed and manufactured in compliance with DNV 2 7 2 are intended to meet the basic. requirements of SOLAS MODU code and DNV Offshore Standards relevant to the functions of the equipment. and as applicable at date this standard was issued All subject to adequate installation of the equipment. when located on the offshore installation which is out with the scope of this standard. DNV DNV GL and associated logos are registered trademarks of DNV GL AS and may not be used without. prior permission of DNV GL, 1 1 Relationship with other standards codes and regulations. 1 1 1 The International Maritime Organization IMO, The requirements in the SOLAS Code apply for Offshore Service Modules utilised on ships and certain. floating offshore installations The requirements in the MODU Code apply for offshore service modules. utilised on floating offshore drilling units including jack up installations This applies irrespective of the time. such modules are installed and used, DNV 2 7 2 is intended to meet the basic safety requirements of SOLAS and MODU code with regard to. escape provision fire detection and fire protection. 1 1 2 DNV Rules for Classification of Ships DNV Offshore Standards. Offshore service modules that are installed on a DNV GL classed offshore Installation may be subject to. classification requirements either in main class or other class notations DNV 2 7 2 includes the basic. requirements of these documents for main class items when applied to temporary installations DNV 2 7. 2 is not intended to replace certification to the DNV Rules for Classification of Ships DNV Offshore Standards. for permanently installed equipment or conversions Equipment needing type approval or product. certification or type approval certificate as defined in DNV Rules for Ships or Offshore Standards shall be. certified in accordance with the relevant rules standard prior to commissioning and use in a DNV 2 7 2. When equipment is located on a DNV GL classed offshore installation it is required to be assessed by DNV. GL to ensure any aspects which interface with a class systems have been correctly installed and to ensure. that general safety principles have been adhered This considers the location integration of the equipment. and confirms that relevant installation and hook up requirements specified in the DNV GL product certificate. have been satisfied It is not the intention of this standard to address the requirements for commissioning. on a DNV GL class unit these remain the responsibility of the vessel offshore unit owner manager. 1 1 3 Relationship to previous revisions of this standard. This revision has been published to provide additional information and clarifications on a limited number of. existing requirements as presented in the May 2013 edition with the intention of simplifying the. implementation of these requirements Minor typing errors have also been corrected in this revision. Design assessment and certification to the previous revision of this standard shall not be conducted six. months following release of this revision, Standard DNVGL ST E272 Edition February 2016 Page 7. SECTION 2 GENERAL,2 1 Objective, The objective of this standard for certification is to set requirements for offshore service modules focussed.
on the safety impact to the offshore installation upon which the equipment is installed. When installed and used on floating offshore installations service containers are subject to the regulations. applicable to an offshore installation i e IMO MODU SOLAS Class flag state and national regulations. When offshore service containers are installed and used on fixed offshore installations national regulations. will apply, It has been recognised that individual interpretations of all the various codes and standards may sometimes. lead to conflicting requirements This standard for certification intends to prescribe solutions which will. provide an equivalent level of safety as the codes and standards referred to throughout this document. Certification by DNV GL provides a document which may be presented to users of the module to document. its technical standard and safety performance The certificate also defines conditions for transportation to. and installation on an offshore installation,2 2 Definitions. Accommodation space, Those used for public spaces corridors lavatories cabins offices hospitals cinemas games and hobbies. rooms pantries containing no cooking appliances and similar spaces Public spaces are those portions of. the accommodation which are used for halls dining rooms lounges and similar permanently enclosed. Guidance note, The term cabins relates to sleeping areas Offices are considered as spaces for paperwork administrative tasks only Facilities for. office work incorporated into the same space as low voltage control monitoring equipment or laboratories without an internal source. of release would not be considered an office accommodation space. e n d of g u i d a n c e n o t e,Category A machinery space.
All spaces which contain internal combustion type machinery used either for main propulsion or for other. purposes where such machinery has in the aggregate a total power of not less than 375 kW or which contain. any oil fired boiler or oil fuel unit and trunks to such spaces. Certified safe equipment, Certified safe equipment is equipment certified by an independent national test institution or competent. body to be in accordance with a recognised standard for electrical apparatus in hazardous areas. Essential safety system, Module integrated systems including required utilities which are provided to prevent detect or warn of an. accidental event and or mitigate its effect This may include. fire and gas detection systems,shutdown systems,PA GA systems. supplies from emergency power or UPS sources,fire protection and extinguishing system. Extreme location, Areas which are out with the range of locations defined for Mid point location.
Doors walls or dampers which will maintain a pressure differential between adjacent areas the allowable. leakage rate will not exceed 0 5 m3 m2h at 50Pa, Standard DNVGL ST E272 Edition February 2016 Page 8. Important services, Services provided by the module to the offshore installation which are critical to the safety of the offshore. installation or modules that prevent protect or mitigate from the effects of an accidental event Examples. may include accommodation units emergency generator units well intervention equipment. Low flame spread,A surface which in accordance with the IMO Fire. 1 1 2 DNV Rules for Classification of Ships DNV Offshore Standards Offshore service modules that are installed on a DNV GL classed offshore Installation may be subject to classification requirements either in main class or other class notations DNV 2 7 2 includes the basic
