EXAMPLE 2 Vehicles, communication systems and appropriate tools. 4.2 Competence The qualification of competent persons involved in the design, construction, operation and maintenance of a gas infrastructure, or parts of it, shall be in accordance with the characteristics of the pipeline system they are working on. These characteristics include, but are not limited to the following: SIST EN 12007-1:2013
Pressure relationships MOP a (bar) TOP ≤ MIP≤ STP/CTP > 5 < P ≤ 16 1,2 MOP 1,30 MOP MIP 2 < P ≤ 5 1,3 MOP 1,40 MOP MIP 0,1 < P ≤ 2 1,5 MOP 1,75 MOP MIP P ≤ 0,1 1,5 MOP 2,50 MOP b MIP a These relations are only valid when DP = MOP. b When gas appliances, tightness tested at 150 mbar, are directly connected to installation pipework, the MIP downstream of the regulator shall be limited to 150 mbar.
MOP shall be equal to or less than the design pressure of the system, including its components. The maximum set value of the active pressure regulator in the working stream shall not exceed MOP. NOTE Where MOP is less than DP, the pressure relationships given in Table 1 may be related to DP.
EXAMPLE Where DP is equal to 0,1 bar and MOP equal to 0,075 bar TOP can reach 1,5 × 0,1 bar and MIP can reach 2,5 × 0,1 bar. For information on specific pressure settings reference should be made to EN 12186 and EN 12279. 7.4 Pipeline sections 7.4.1 General Pipeline sections shall be supported, anchored or buried in such a way that, during their lifetime the pipeline sections will not move with respect to their installed position, except for the foreseen permitted displacements. Submerged pipes shall have enough own weight or outside loading during the construction and operation phases to guarantee horizontal and vertical stability. The pipe wall thickness selection should be based on sufficient resistance to internal pressure and also the forces expected during handling and transportation. Additional measures should be provided as necessary to protect the pipe against third party damage, these measures include, but are not limited to the following: increased depth of cover; a control zone along the pipeline route; increased wall thickness; additional mechanical protection; and increased frequency of surveillance. SIST EN 12007-1:2013
EXAMPLE 3 Insertion into an existing pipe. In the planning and laying of underwater crossings the geological conditions of the ground should be known and appropriate precautions taken. EXAMPLE 4 Possible mobility of the waterway bed. EXAMPLE 5 Loading or anchoring the pipework to counteract buoyancy effects. The depth of pipework below or on the bed of the waterway shall be chosen to protect it from any foreseen activity in the use of the waterway. EXAMPLE 6 Anchoring of vessels. The position of pipework crossing major waterways shall be clearly marked. 7.4.7 Limiting interference from external causes 7.4.7.1 General The risk of interference with the gas infrastructure by other buried plant, ground movement, trees, other structures or traffic should be minimized at the design stage considering the guidance given below. Safe operating and liaison procedures shall be agreed between the pipeline operator and relevant third parties.
EXAMPLE 1 Other utilities. EXAMPLE 2 Highway, bridge, waterway and rail authorities. SIST EN 12007-1:2013
EXAMPLE 2 Precaution: soil replacement / applying casing / choosing suitable pipe material. SIST EN 12007-1:2013
Suitable protection shall also be given to metallic sleeves used for plastic gas pipes. The use of steel sleeved crossings should be minimized as they can cause adverse effects on cathodic protection systems. When steel sleeves are used, they shall be designed such that: a) they are capable of withstanding external loads; b) the gas pipe is easily installed; c) cathodic protection of the steel gas pipe can be provided if necessary; d) they can be sealed effectively or
filled with a suitable material to minimize water circulation and thus reduce the oxygen supply to a minimum; e) the gas pipe is provided with an adequate and suitable support and provision is made, especially at the extremities of the sleeve, to avoid the possibility of contact between the gas pipe and the steel sleeve; f) adequate supports shall be provided considering operating and test conditions.
7.9.5 Sections of gas mains and services made of steel installed in the open air shall be externally protected.
EXAMPLE By painting, electro-plating, coating or another appropriate method. 7.9.6 Sections of gas mains and services made of steel shall be electrically insulated from adjacent metal structures or works except when electrical connections are intended for the corrosion protection system. 7.9.7 Cathodic protection shall be provided for buried gas mains and services made of steel where such protection is considered necessary. Its purpose is to ensure that at all times and at all points in the gas mains and services the potential relative to the ground will be sufficiently negative to protect the gas infrastructure from corrosion. 7.9.8 The design of cathodic protection systems shall take account of the effects of possible stray currents, especially from electric railways and other sources. 7.9.9 When steel or other metallic pipework is installed close to any existing cathodic protection system or in an environment where stray currents can occur special care shall be taken in order to avoid electrical interference. NOTE It is beneficial to liaise with the operators of adjacent cathodic protection systems. SIST EN 12007-1:2013
8.3 During the laying of gas pipelines special precautions should be taken to minimize the disturbance to adjacent drainage networks and other buried installations. 8.4 Inconvenience to road users caused by construction, maintenance or operation of the system should be minimized by appropriate techniques. EXAMPLE By the use of trenchless technology. 8.5 During construction all reasonable measures shall be taken to avoid damage to trees and other vegetation. Above ground parts of the gas infrastructure such as regulating and measuring stations should be designed and located in order to reduce environmental impact as far as reasonably practicable. 8.6 All unwanted materials or waste shall be disposed of properly in an environmentally friendly manner. 9 Transportation, storage and handling of materials 9.1 Care shall be taken during the transport, handling and storage of pipes, fittings and other items to avoid damage to the materials and ensure the safety of personnel. 9.2 At all stages damage and distortions to the materials should be avoided and the effects of environmental factors should be minimized. All materials should be stored under appropriate environmental conditions and shall be used within any specified constraints. EXAMPLE Expiry date or UV degradation limits. 9.3 Full attention shall also be given to the general safety of all personnel, members of the public and to adjacent property at all times during handling operations. 9.4 For safety reasons only the correct equipment shall be employed where mechanical handling is necessary and manual handling shall be undertaken by competent persons within their weight limit capabilities. Handling equipment shall be visually checked before use. 9.5 Particular details for transporting, storing and handling the materials for each kind of system are given in EN 12007-2 and EN 12007-3. 10 Construction 10.1 General The safety of personnel engaged on gas supply works and of members of the public shall be ensured during the whole period of the works. Considerations shall be given to the needs of the elderly or disabled. After transport, storage and handling and before assembly on site, the condition of pipes, their coatings, and fittings shall be checked. Before assembly and laying, all pipes and fittings shall also be checked for unwanted obstructions or blockages. Gas mains and services lines shall be laid only by competent persons using the appropriate equipment necessary to complete the work in conformance with the relevant standards. SIST EN 12007-1:2013
