POWER PLANT PRESENTATION 2016

SUMMARY OF MAJOR INTERVENTIONS ON DESIGN AND SUPERVISION OF POWER PLANTS

It has been followed by interventions of different complexity, at Unimar TPP inAmbarli (TR); Bandirma Natural Gas Combined Cycle Power Plant, 936.5 MW (TR);Aliağa Thermal Power Plant, 350 MW (TR); Mesaieed (Qatar) ; Bekirli Coal-firedThermal Power Plant - 2x600 MW (TR); Al-Khalij Thermal Power Plant, 4x350 MW(Libya); El Ain El Sokhna Supercritical Thermal PP - 2x650 MW (Egypt); SamsunCombined Cycle Power Plant, 870 MW (TR); Atlas Iskenderun Coal-fired Thermal PowerPlant - 2x600 MW

Apart earlier interventions on the design of marine pipelines and intake structures, a “full immersion” in the power plant sealine design and supervision started with the Sugözü - 2x605 MW Power Plant in Turkey

The presentation does not include all other sealine projects, ie. outfalls, pipelines for desalination plants and collateral activities, which are covered by a more general presentation of Avanzini Middle East.

AMBARLI, UNIMAR THERMAL P0WER PLANT (2005)

Construction of new tapered diffuser, removal of the existing one and connection of the new one to the main line.

Contractor: STFA (TR)

The need of the substitution of the original diffuser with a new one to be connected to the main GRP pipeline ND2500 was originated by updated thermal discharge requirements

While the construction of the new diffuser on piling did not present in itself particular problems, the removal of the old from the main line and the connetion of the new was “space and time limited”


It was requested to perform the connection respecting the existing alignment and executing the intervention in less than 12 hours to ovoid the interruption of the production.

The SOW was the study, together with the client’s and contractors engineering team, of the necessary connection tolerances and of the pipe spools and accessories to compensate such tri-dimensional tolerances

A combination of GRP short spools and of tailor-made steel bolted Compression Couplings, designed with ±200 mm longitudinal insertion tolerance and ± 3° allowable angular deflection has been used to compensate the installation misalignment.

The arrangement permitted the realization of the tie-in in ≈8 hrs, practically without disturbance to the TPP operation.

MESAIEED A (QATAR) 2009LAND SECTION OF INTAKE LINE GRP ND 1800

ND 1800, 6 km long intake line on land under water table level

The request of expertise had two main aspects. The first was the peer-review of the main calculation

aspects, i.e. hydraulics, deflection, ovalization etc. and the analysis of the possible tolerances.

The second aspect was the analysis of the leaks which appeared after backfill and of their repair with internal lamination using a technique and

materials proposed by the pipe supplier.

With a few exceptions, all measured data of gap, deflection and ovalization were well within the design limits.

In a dewatered pipe, the system is acceptable and has proven leakproof.

GRP ND 3500, 450 mm long intake line with a 90m semi-buried diffuser at -35m

The SOW included several stages• The coordination and assistance in the field to the

surveyor and assistance in the reporting• Hydraulic and diffuser calculations and outline

design • Preparation of the documents for the Ministerial

approval

• Analysis of the seismic profiles to define the safest route and choice of

the centre line


After the choice, it was studied a safe stabilization system along the 27% slope.

The risk was not only the sliding downwards of the pipe, but also the eventual settlement.

The solution was found by using 6 lateral marine lugs and pipes with anti-sliding ribs.The upper bend was connected with a steel compression coupling permitting a ±3° angular deflection and the lower one was anchored by a thrust block.

POWER PLANT PRESENTATION 2016[SOKHNA 2]

The second part of the SOW has been the peer review of the design “for construction”, the evaluation and assessment of the installation method, a part time installation control and the verification of the pipe joints .

POWER PLANT PRESENTATION 2016[SOKHNA 3]

The pipes were connected across the joint with marine lugs. Part of them were kept tight and part released after installation.A 16mm gap inside and a maximum 0.5° was specified at each joint by the client. However, the couplings tightness had been tested in the factorywith a 63mm gap and 1.2°at 9 bar without leaks.

The measure of gaps in different stages of installation brought to an animated discussion and to the definition of limits agreed between client, pipe producer and contractor and accepted by us.The study about the tolerances was the most interesting part of the supervision.

The values of gaps in 4 points at each couplinghave been recorded immediately after each pipe’s installation and after the completion of 100-120m sections before the backfill. Only minor changes due to local settlements have been found and eventually corrected,


After the examination of the geometric parameters with the pipe supplier, it was presented to the client a revision of the acceptable values (after backfill) proposing 90 mm gap and 0,9°as “safe”. In theory, larger gaps could be exceptionally accepted, provided that the position of the gasket from the coupling edge was at least 25mm (defined as “gasket not visible”)

[SOKHNA 4]

It must be noted however that the value of tolerances depend from the diameter, the geometry of pipe spigot and of the double bell coupling.

The comparison of the values “before and after” demonstrated that with the enhanced safe value of the tolerances only 3% of the joints needed a repair, mostly due to the displacement of the gasket.
