INSTALLATION OF A METAL STRUCTURE UNDERNEATH C-31B HIGHWAY’S RACK, TARRAGONALocation: Catalonia, SpainCustomer: REPSOL PETRÓLEO


Given REPSOL’s commitment towards local administrations af-fected by its activity, the company decided to create an actionplan named “Integral Coastline Protection Plan” which inclu-des a number of improvements aimed at renewing their assetsand minimize the risk of possible leaks on the right bank of theFrancolí river, aerial rack, dock and Casablanca platform.

The improvements will consist in the installation of a metalstructure underneath the rack on its passage through C-13BHighway.

The purpose was to improve the existing infrastructure. Thissystem will gather possible leaks and drain storm water wi-thout interfering with the highway’s own drainage system andclearance area.

The works were as follows:

Urbanization of a land plot, currently used as a par-•king lot, by paving it and building sidewalks. The lot’stopography, slope and drainage were kept unchan-ged thus preventing its flooding. A cabin was built toserve as a security gate, provided with water, electri-city and septic tank.New access road for heavy vehicles and sidewalk for•pedestrians. The road has traffic on both directionsand a 15 m parking area. Changes were also perfor-med on the fences by installing control access gatesfor heavy vehicles. The southern area of the lot willhave a turnstile for pedestrian access control.

Both the urbanization and the construction of the road inclu-ded the following works: paving, signaling, sewerage and po-table water supply networks, public lighting, energy supplyand fire fighting systems.

STUDY OF ALTERNATIVES. 3RD OVOID PIPE RACK BENEATH C-31B HIGHWAY IN TARRAGONALocation: Catalonia, SpainCustomer: REPSOL PETRÓLEO


There are two ovoid pipe racks beneath C31-B highway, from Tarragona to Salou. One carries REPSOL’s PETRÓLEO pipe rack andthe other was left empty. REPSOL uses the ovoid to monitor and perform maintenance operations but its extension meant that se-curity and maintenance personnel could not access it. The purpose of this work was then to define and estimate a third rack alter-native next to the existing ones, allowing the passage of vehicles and its surveillance and monitoring.

The scope of the works was as follows:

Compilation of available plans of the area in study, from various sources, providing a reliable basis to conduct the study•and a photographic survey to facilitate the understanding of its current state;Consultation with Generalitat de Catalunya’s (The Autonomous Government of Catalonia) roads service;•Study of 5 alternatives, graphical representation and budget estimate.•

ADMINISTRATIVE PROJECTS. REHABILITATION OF A LOW DENSITY POLYETHYLENE INDUSTRIAL PLANT IN TARRAGONALocation: Catalonia, SpainCustomer: DOW CHEMICAL IBÉRICA


The project aimed to establish Dow’s best technology to high pressure reactors, which basically consisted in dividing the ethylenefeed to the reactor in two (50/50), and have 4 catalyst injections instead of the current 2. To add two new catalyst injections itwas necessary to build two new deposits (mixing and injection) and 3 new injection pumps. In addition, the reactor’s length hadto be increased by adding input tubes. The cooling water network had to be modified to optimize the transfer of heat.

A new telomere system was also added. The telomere is currently stored in a carbon steel deposit and a new stainless steel tankand pump injection shall be installed.

The project also included replacing the extruder’s motor, from direct to alternating current, hence requiring the construction ofa storage facility to host a drive and a transformer. The changes improved the plant’s capacity in 15%. The works consisted in:
