For engines with rated power less than 300 kW, the product certification need only be based on the applicableelements of design approval in [2] and workshop testing in [4] and [10] . For dual-fuel and gas-only engines,see [1.1.2].The requirement for product certification may be waived for diesel engines with rated power less than 300kW when the engine is type approved.Table 1 Certification requiredObjectCertificate typeIssued byEnginePCSocietyCertification standard*Additional description*Unless otherwise specified the certification standard is the Society's RulesFor general certification requirements see Pt.1 Ch.3 Sec.4.For a definition of the certification types see Pt.1 Ch.3 Sec.5.1.1.11 Engines manufactured under licenseFor each engine type manufactured under licence, the licensee shall submit the following documents forapproval:— comparison of all the drawings and documents as per Table 2, where applicable, indicating the relevantdrawings used by the licensee and the licensor— all drawings of modified components, if available, as per Table 2 together with the licensor's declaration ofconsent to the modifications— a complete set of drawings or list of approved drawing shall be put at the disposal of the local inspectionoffice of the Society as a basis for the performance of tests and inspections.1.1.12 Definition of engine typeThe type specification of an engine is defined by the following rer's type designationcylinder borestrokemethod of injection (direct, indirect)valve and injection operation (by cams or electronically controlled)fuels which can be used (liquid, dual-fuel, gaseous)working cycle (4-stroke, 2-stroke)method of gas exchange (naturally aspirated or supercharged)rated power per cylinder at rated speed as well as mean effective pressure, see [2.1.6]method of pressure charging (pulsating pressure system or constant-pressure charging system)charge air cooling system (with or without intercooler, number of stages)cylinder arrangement (in-line, vee).1.1.13 Engines driving generators in electric propulsion systems shall be equipped with sensors andmonitored as propulsion engines (Table 10) and with safety actions according to Table 11.Rules for classification: Ships — DNVGL-RU-SHIP-Pt4Ch3. Edition October 2015Rotating machinery - driversDNV GL ASPage 9Part 4 Chapter 3 Section 11.1.10 Certification requirementsEngines shall be delivered with a product certificate according to Table 1 that is based on the applicableelements of design approval in [2], testing and inspection in [3] and the workshop testing in [4].

1.2.1 GeneralDrawings, data, specifications, calculations and other information shall be submitted as applicable accordingto Table 2, Table 3 and Table 4, except for items covered by a valid type approval.1.2.2 Design modificationsFollowing initial approval of an engine type by the Society, only those documents listed in Table 2 to Table 4which embodies design modifications shall be resubmitted for approval.1.2.3 Approval of engine componentsThe manufacturers shall request approval from the Society for exhaust gas turbochargers, torsional vibrationdampers, crankcase relief valves etc, see [11] for more information.
