The largest LEWA chemical injection package

In 2015, LEWA completed its largest package to date: The LEWA chemical injection package for use on Brazilian floating production storage and offloading unit (FPSO) weights 715 tons and measures 21.3 x 21 x 11 meters. This ambitious project represents a large challenge to our engineers. The LEWA giant has been implemented in more than 7,500 engineering hours. LEWA once again confirmed their one-of-a-kind expertise as the global leader in pump manufacturing and system integrator with this special solution.

Chemical Injection Package for offshore application on a FPSO.

Pump manufacturer and system integrator LEWA designed and produced the biggest chemical injection module in the company’s history. The huge package is designed and manufactured by LEWA subsidiary in Singapore. The customer's requirements as well as the organizational and logistical effort for this project were very demanding.

For the ambitious and experienced LEWA experts, it was a big challenge, which they could cope with flying colors. 2015, the giant was completed: The Chemical Injection Package is used on a Brazilian FPSO. A FPSO is a colossal production ship for oil production, storage and loading.

Enormous dimensions

With dimensions of 21.3 x 20 x 10 meters and an estimated weight of 715 tons, the chemical injection module surpasses all previous packages designed by LEWA. All together, there are three levels present in the module. 40 diaphragm pumps and 40 IRCDs can be found on layer 1, layer 2 houses 18 tanks (210 m³) and a GFK tank (5 m³). The platform on layer 3 contains 27 individual tote‐tanks.

High-quality components

40 diaphragm pumps, 40 IRCDs, 18 storage tanks, and over 3,000 instruments, valves, and more than 3,500 meters of piping and tubing were installed. The components were selected extremely carefully to ensure a safe and efficient operation of the package.

World's most advanced diaphragm pump technology

The technological centerpieces of the giant Chemical Injection Package are more than 40 LEWA diaphragm and process pumps according to API 675 standard. LEWA is the leading manufacturer of diaphragm pumps with the world's most advanced pump head technology. Coupled with the 40 IRCDs, the pumps allow the precise and targeted injection of chemicals in more than 120 points.

Unique engineering expertise

LEWA has a comprehensive know-how in the field of applications in the oil and gas industry. In order to offer a perfect solution for our customer, more than 7,500 engineering hours were needed to realize the giant package. In 2010 and 2012, LEWA already integrated two custom packages on FPSOs – one with three and one with two levels, each with a total of 36 pumps.

Involvement of our customers in the engineering process

The complete module has been modeled with a plant design management system in 3D and validated by the EPC to avoid potential weaknesses in the different phases of package engineering and to ensure that the design meets all requirements to the operator's complete satisfaction.

Ergonomics and safety

The arrangement of the components is not only compact, but also ergonomically operable, thus there is no health risk for the operators. The handling of the components is made possible by ten overhead monorails and a davit for a weight of one ton. LEWA designed and installed a complete water spray extinguishing system and light fittings with explosion protection. As prescribed by the NORSOK S2 standards for working environments, access and exit paths were generously dimensioned, despite the limited area.


Compact arrangement

All equipment for the nine- and seven-headed pump systems had to be placed on minimum space in order to realize a compact solution for the extremely limited space available on the FPSO.

Compliance with technical standards and requirements

The pumps and pipelines were made of special titanium materials to be resistant against highly corrosive chemicals. The storage tanks made of fiber compound materials were designed according AMSE-RTP-1 standard. In accordance with the Brazilian NR standards, special color codes were used for the identification of basic, acidic and neutral chemicals.
