2. OIL & GAS

2.1 Standards x CAE

The design rules of an offshore structures are based on analytical methods, but the

FEA´s applications are growing up. Bureaus like DNV, API, BS, ASME have been introduced

FEA in their standards improving accuracy of a calculation and solving multi physics

problems as well.

2.2 Industrial Valve - Brazilian Standard NBR 15827

NBR 15827:2007 describes the rules for homologation of "Industrial Valves For

Exploration, Production, Refining and Transport of Oil Products". This Standard specifies

the requirement projects and essays of the following valves: check, gate, globe, ball,

butterfly. Introduction of FEA based on the methodology described on Design by Analysis –

ASME - Chapter 2007 Section VIII, Division 2, is an innovation. This Standard contains

criteria to design according to plastic collapse, local failure, buckling and fatigue life.

NEP joined this process making consultancy services, applying training courses and

checking calculations as the Certifying Consultant of Bureau Veritas and SGS.

2.3 Fracture Mechanics

2.3.1 Damaged Structures Study

Determination of the stress intensity factor, integral J and studies about damage

mechanics following standards.

Figure 5 – Pipeline Crack FEM Model

2.3.2 ECA

Engineering Critical Analysis (ECA) checks a damaged structure, mostly concerned

with welding failure. This method determines a maximum failure size allowable to maintain

a stability of the structures. ECA follows the standards BS 7910 and DNV 101.

2.4 Pipeline Repair

2.5 Calculation of Flange

A flange was calculated following ASME VIII Division 2, verifying a local and a global

plastic strain and a ratcheting effect. The linearized stress transformation is used to make a

classification of the stress according to primary or secondary stress.

Figure 7 - Calculation of a Flange According ASME VIII D2

2.6 Intensification Stress Factor - Calculation of Joint Flexibility

This study calculated the intensification stress factors of not usual diameters of pipeline

connections. These parameters are included on flexibility studies. Different loading

conditions in-plane and out-of-plane indicated on standards are applied to calculate the

factors under internal pressure.

2.7 High Pressure Hose

High pressure hoses are components of umbilical cable manufactured for offshore

industry. The hoses are composed of textile reinforcement layers (Kevlar®), nylon,

polyurethane and steel carcass.

This work proposed different models for representing the layers, the contact between

them and calculates the pressure and fatigue strength of this assembly. At the end of hoses

are plugged steel connections by crimp or swaging process which can produce some

damage in a textile layer. This work introduces different models of failure in Kevlar®.

2.8 Modules of FPSO

A design of topsides structures assembled on the deck of the FPSO (Floating,

Production, Storage and Offloading) Platform to withstand the equipment for processing an

extracted oil is indicated by the DNV (Det Norske Veritas) and API (American Petroleum

Institute) offshore standards for structures. A typical FPSO contains around 18 modules,

each one composed by structure and equipment, as heavy as 3,000 tons, measuring about

20 m each side. Hundreds of different loads and load combinations - especially given by the

environmental data - material properties and boundary conditions are key inputs for analysis

of any structure.

The structure should be in accordance with various design criteria: installation and in-

place conditions. The installation conditions are composed by three different analyses:

hydrotest, design transit condition and lifting. The in-place analysis: static, design operation

condition (DOC) and extreme condition (DEC), damage (DAC), blast, fatigue and the

assessment of the flare tower. The structural analysis were executed on CAE software

package developed by DNV (Genie/Sestra).

Page 12: Engineering Consulting Nucleus and Technology … Consulting Nucleus and Technology Research NEP 2 Contents List of Figures ..... 4 ... Joints of Offshore Structures Calculation.....

12

The design of these structures requires a number of revisions due to the constant

equipment changes and information updates from other disciplines that contribute to the

construction of the platform.

This work reported the structural calculation of FPSO´s Modules covering oil

processing modules, gas compression modules, power generation modules etc., piperack,

and laydown areas. It was executed all calculations on primary, secondary and tertiary

structures, fatigue life and blast.

Figure 11 - Module of FPSO

This work was developed in an association with the Oceânica Engineering Consultancy

and Projects Ltda and the Brazil Shipyard (EBR/ Toyo-Setal Group).

2.9 Analysis of Joints on Modules and Pipe Rack - FPSO

This work developed an evaluation of a fatigue life of offshore structures (modules,

pipe rack) joints. Stress intensification factors were calculated according to DNV-RP-C203

standard, using local model built in shell finite element. This work was developed for the P66

and P74 platforms of Petrobras.

2.10 Weight Optimization of Metallic Structures

The FPSO (Floating, Production, Storage and Offloading) platforms are improving and

increasing processes and oil & gas extraction capacity. As a result, the overweight is

becoming a problem to the stability and the storage capacity of ships. This study did a

multidisciplinary approach about weight optimization.

The main target is to reduce the weight of the structure of the modules that withstand the

processing equipment. These structures, easily weigh one thousand tons.

Figure 13 - Module of FPSO

This work proposed three approaches: material exchange of metal for plastic, usage of

recent DNV´s Recommended Practice Based on Non Linear Methods (DNV RP-208) and

optimization of mass by using specific software.

Plastic Polymers - Plastic material has advantages: high stiffness-weight ratio, recyclable,

low corrosion and wide range of mechanical properties modifiers (glass fiber,mineral). There

are drawbacks: variations of mechanical properties regarding temperature, high creep, and

processing variables - fiber orientation, welding lines, warping and voids. This project uses

composite honeycomb sandwich panels for the floor and a high performance polyamide

resin for the structure. The Finite Element Analysis (FEA) was performed to compare the

results between steel and the equivalent of the stiffness of the plastic structures.

DNV RP-208 – The nonlinear criterion defines a plastic strain limit for the structure. This limit

permits an increase in the loads. FEA was carried through comparing the linear - Allowable

Stress Design (ASD) - and the nonlinear criteria.

Optimization – Applying optimization software based on parametric and topology techniques

may be determining lightweight structures according to the design criteria.

A pilot project in reference to the structure of a compressor skid was executed to apply

the methodology. The results show that all approaches have a potential to reduce material

weight.

The exchange of plastic material shows a competitive cost/weight ratio with an equivalent

Page 14: Engineering Consulting Nucleus and Technology … Consulting Nucleus and Technology Research NEP 2 Contents List of Figures ..... 4 ... Joints of Offshore Structures Calculation.....

14

performance compared with steel.

Figure 14 - Skid Displacements

The application of nonlinear criteria is ready to be put into practice. The nonlinear criterion

becomes possible for the skid´s structure to withstand loads four times more than the linear

criterion.

Optimization using parametric techniques permits the final structure to be at least 20%

lighter than the original structure. Topologic studies can even improve the results.

This work was developed in an association with the Oceânica Engineering Consultancy

and Projects Ltda.

3. MINING

3.1. Crushing Tower

A crushing tower portable is a new concept to improve an equipment mobility in Carajas

Iron Mine.

and a crusher. This structure was calculated on basis of static and dynamic loading. The

simulations were executed on the following situations: starting / stopping run and steady-

state conditions.

3.2. Iron Mineral Hopper

This equipment transports the mineral from the vibrating screen to the conveyors belt.

Eventually, stones were thrown (> 4 ton) against the hopper. This work carried through the

calculation to sizing the beams, plates, anchoring screws and proposes new reinforcements

for the structure to withstand an impact of the stones.

3.4 Rail Road Track - Ties

This project proposed a development of ties to railroads tracks according to the

American Railway Engineering and Maintenance-of-Way Association (AREMA) standard.

The first part were carried out optimization analysis following the cross sections. Comparison

between the optimal sections and commercial sections were performed. The second part is

foreseen the execution of simulations "in situ", modeling the realistic loads and soil/ballast.
