3.0 Construction

3.1 Anchoring in the foundations

3.1.1 Anchor bolts

see Annex 2, Fig. 1 see Annex 2, Fig. 2

The anchor bolts are generally supplied by the foundation manufacturer.

However, delivery by the steel construction manufacturer can be agreed upon on request.

The dimensioning of anchor bolts is according to the agreement made in Petrom OMV Standard J 1001, Pt. 1.3 (as a rule, as part of generating the foundation static calculations) and must be checked by the contractor when generating the steel construction static calculations.

To simplify the support assembly, the base plates are provided with overlarge holes.

Anchor bolts with a diameter less than M 20 must not be used, except for fixing steps, ladders, etc.

3.1.2 Adhesive anchors and masonry bolts

see Annex 2, Fig. 3

For fixing steps, light plinths and light support constructions on foundations.

3.1.3 Anchor plates (connections to concrete structure)

see Annex 2, Fig. 4

The anchor plates are part of the concrete structure supply.

The size and thickness of the anchor plate, the number, length and diameter (and the weld bead thickness) of the anchoring iron in the concrete, are be taken from the static calculations for concrete or steel structures – guidance drawing.

On the steel structure drawing, the centre-line and the top edge of the anchor plate is taken from the foundation drawings.

3.2 Structural connections

Workshop connections must be implemented in agreement with the total economic cost planning for the project, preferably in welded form.

Imbinarile sudate pe santier vor fi pastrate la un numar minim.

In zonele cu mai mult de 5 % deformare al rece (de exemplu tesirea) sudura nu este acceptabila.

Legaturile de preluare momente sau legaturile principale (ex. colturile cadrelor etc. ) vor fi realizate prin sudura sau cu suruburi numai de inalta calitate (suruburi HV ).

Nodurile sau colierele vor fi realizate cu cel putin 2 suruburi M 12, daca nu este prevazuta nici o alta specificatie din calculele statice.

Legaturile cu mai multe suruburi si transferul momentelor mari de torsiune (colturi de cadru, racorduri de presiune etc.) vor fi executate conform EN 20 286 cu pasuire. Imbinarile cu suruburi cu cap ingropat vor fi realizate numai prin folosirea a 75 % a tensiunii admise, in functie de grosimea tablei si numai pentru constructiile usoare.

Pentru pozitionarea niturilor si a suruburilor, normele SR EN sunt obligatorii.

In cazul constructiilor solicitate dinamic gaurile vor fi debavurate.

Definitia zonlor periculoase va fi data de catre responsabilul de proiect al PETROM / OMV , in colaborare cu departamentele de protectie a muncii si pompieri.

3.7 Siguranta la coborare

Pentru platforme si postamente ale aparatelor si coloanelor vor fi montate sigurante de coborire in mod obligatoriu, fara exceptii.

Protectiile de coborire vor indeplinii urmatoarele conditii de baza:

-Inchidere automata pin forta gravitationala sau cu arc;

-Imposibil de deschis inspre directia de urcare;

-Imposibilitatea detasarii neintentionate;

-Potrivite pentru preluarea aceleasi sarcini orizontale ca si palierul la care duc;

-Constructie care sa nu necesite lucrari de mentenanta.

Siguranta de coborire:

Sisteme cu inchidere proprie de siguranta: Anexa 2, Fig. 31 – Fig. 34

Usa pivotanta de siguranta cu cu inchidere cu arc:Anexa 2, Fig. 35

Plase si cosuri de prindere:

Model preferat: bara de siguranta cu inchidere proprie: Anexa 2, Fig. 31

Sigurantele de coborire realizate din lanturi sunt interzise fara exceptie

3.8 Macarale, carucioare de macara si brate rotative

Proiectarea macaralelor si a carucioarelor pentru macarale are loc conform specificatiilor proiectului. Profilul de cerinte pentru specificare si masurare va fi stabilit de catre liderul de proiect PETROM / OMV , in functie de indicatiile de functionare. Se vor stabili sarcinile nominale.

When selecting the railing form, pay special attention to the free finger space on the hand railing

Design details for railings: Annex 2, Fig. 26 to Fig. 30

In special dangerous locations (e.g. rectangular branching of a traverse route from a step etc.), the railing must be equipped with a second knee rail to Form C acc. to DIN 28 017 in the hazardous area.

The hazardous area must be defined by the PETROM/ OMV project manager, together with the Safety and Fire Protection Department.

3.7 Descent and fall protection

For platforms and landings on equipment and columns, fall protection must be provided for all ladders, without exception.

Descent protection must have the following basic features:

-Self-closing by gravitational or spring force

-Cannot be opened up towards the ladder

-Unintentional raising not possible

-Capable of withstanding the same horizontal load as the connected railings

-Maintenance-free design, as far as possible

Descent protection:

Independent safety bracket: Annex 2,Fig. 31 to Fig. 34

Independent descent doors with sping force: Annex 2, Fig. 35

Guard nets and cages:

Preferred design: Independent safety bracket: Annex 2, Fig. 31

Descent protection using chains is forbidden under any circumstances

3.8 Cranes, crane trolleys and swivel arms

The planning of cranes and trolleys is according to project-specific requirements. The requirements profile for specifications and dimensioning must be determined by the PETROM/ OMV project manager according to the operational specifications.

The working loads must be defined.


Bratele rotative Dimensiunile necesare ale tevilor vor fi calculate in functie de sarcina nominala indicata. Sarcina calculata a bratului rotativ = 2,5 x sarcina nominala

Petru masele a, b, c, d, si e vor fi preluate valori de pe constructia metalica respectiv de pe desenele de recipienti.

Model preferat: DAVIT : Anexa 2, Fig. 36 si Fig. 37

Swivel arms

The required pipe dimensions must be calculated according to the specified working load. Calculated load of the swivel arm = 2.5 x working load

Dimensions a, b, c, d, and e must be taken from the steel structure or equipment drawing.

Preferred design: DAVIT:
