EN 13121-4:2005 (E) 4 1 Scope This document gives requirements for delivery, installation and maintenance of GRP tanks and vessels in accordance with prEN 13121-3. 2 Normative references Not applicable. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 delivery delivery includes loading, transportation and off-loading of the GRP tank or vessel at the site designated by the purchaser 3.2 installation installation includes the preparation of the support(s), erection or placement on the supports and fixing the tank or vessel, inspection and tests before commissioning 3.3 bedding material bedding material for flat-bottomed tanks, pliable during installation and load bearing before commissioning 3.4 screed hard setting material to correct minor surface irregularities 3.5 transporter organisation in charge of the transport of the tank/vessel from the place of loading to the place of storage or instal-lation 3.6 installer organisation in charge of installing the tank/vessel in its place of use 4 Delivery 4.1 General If the manufacturer considers that the requirements of this document are insufficient for the loading and the transpor-tation of the GRP tank or vessel for the purposes of any particular delivery, he shall provide the necessary additional information. NOTE A recommended check list of those items which should be verified is given in Annex C (informative). 4.2 Low temperature effects The possible effects on the material properties of the GRP tank or vessel of ambient temperatures experienced during transportation shall, as far as possible, be taken into consideration, especially temperatures less than 5 °C. SIST EN 13121-4:2005

EN 13121-4:2005 (E) 5 4.3 Pre-delivery check A pre-delivery check shall be made to ensure that:  the appropriate inspection certificate is available;  the tank/vessel is correctly identified;  the tank/vessel is in its as-released condition;  all branches are blanked with either service blanks or temporary covers. NOTE To avoid damage to the GRP tank or vessel during delivery, temporary bracings should be used. 4.4 Storage If, after unloading, the GRP tank or vessel cannot immediately be installed in its final position, it shall be stored as

follows: a) Wherever possible the GRP tank or vessel shall be stored in the design orientation i.e. vertical tank or vessel shall be stored (supported and anchored) vertically. If it is not possible to store the item in their operational

orientation it may be stored otherwise with special considerations on supporting and anchoring. The use of saddles or supporting timbers with wedges may be necessary. b) The storage area shall be level and free from protrusions or ridges to avoid point loading. The GRP vessel or tank shall be located in an area remote from vehicular traffic or suitably protected from traffic. Consideration shall be given to movements due to wind on the empty item and temporary anchors shall be provided. 4.5 Lifting devices Where the lifting device will make direct contact with GRP surfaces, synthetic fibre flat webbing slings shall be used. The minimum width of the slings shall be 80 mm. 4.6 Loading The GRP tank or vessel shall be lifted and handled in a suitable manner according to the state of the art; appropriate manners are shown in the examples in Annex A (informative) and Annex B (informative). The lifting devices shall be attached to the GRP tank or vessel in correspondence with the design of the tank or

vessel. All lifts shall take into the consideration the site and atmospheric conditions, especially wind. All lifts shall avoid any impact. Loading details shall be recorded.

NOTE This may be done by e.g. using the form given in Annex C (informative). 4.7 Transportation Loads occurring during transport shall be considered to ensure that undue stress, local loads and abrasion are not imposed on the GRP tank or vessel. The GRP tank or vessel shall be secured by webbing slings or ropes. NOTE At the destination and before off-loading the GRP tank or vessel should be visually inspected. The results of inspec-tion should be recorded, e.g. using the form Annex C (informative). SIST EN 13121-4:2005

EN 13121-4:2005 (E) 6 5 Installation 5.1 General The manufacturer shall advise the methods of installation of the GRP tank or vessel. NOTE 1 The installation should be carried out by trained personnel only. NOTE 2 The details of installation should be recorded, e.g. using the form given in Annex D (informative). 5.2 Pre-installation checks A pre-installation check shall be made to ensure that: a) supporting structures or foundations are suitable for the installation; b) supporting structures or foundations are within the specified tolerances; c) if necessary, the item is protected from flotation. Pre-installation details shall be recorded, e.g. using the form given in Annex D (informative). 5.3 Preparation of installation location 5.3.1 Requirements for installation surfaces The supporting structure shall meet the requirements of the manufacturer of the GRP tank or vessel. 5.3.2 Preparation for support and erection of tanks or vessels 5.3.2.1 Flat-bottomed tanks or vessels a) Installation on flat and even surfaces The foundation shall be flat and level within 2 mm/m with an overall maximum deviation of 5 mm. Flat-bottomed tanks/vessels shall be erected vertically with a maximum deviation of 0,5°. b) Installation using a bedding material On uneven foundations or in case of uneven tank or vessel bottoms, a fresh bedding material of a sufficient

thickness shall be used to ensure contact between the foundation and the bottom. NOTE The bedding material, e.g. cement screed, polymer concrete, sodium/potassium water glass sand mixtures and

bituminous sand mixtures, rubber, bitumen felt should be laid shortly before erection ensuring that any orientation marks are visible. The bedding material should be covered to prevent adhesion to the tank/vessel. c) Installation on piers or beams Installation on piers, beams or gratings shall be in accordance with the design. 5.3.2.2 Horizontal tanks/vessels Saddle supports shall be as designed. NOTE The saddle support should be installed with a tolerance of ±1 mm/m separation. SIST EN 13121-4:2005

EN 13121-4:2005 (E) 7 5.3.2.3 Circumferential skirt supported vertical tanks or vessels The tank or vessel shall be installed vertically with a maximum deviation of 0,5°. The alignment may be achieved by placing suitable load-bearing shims, on either side of the anchor bolts. Any gap between the skirt and the supporting structure shall be filled with a load-bearing infill before commissioning. 5.3.2.4 Tanks or vessels with supporting legs Tanks or vessels with supporting legs shall be installed vertically with a maximum deviation of 0,5° and securely

anchored to the supporting structure. The legs sh
