Wilhelmsen Technical Solutions (WTS) has won an order from Brazil’s national oil company, Petrobras, to deliver its maritime protection inert gas generator (IGG) systems to be equipped on floating production, storage and offloading (FPSO) vessels serving deepwater oil fields in Oslo, Norway.

Under the deal, Wilhelmsen will deliver eight dual-fuel maritime protection IGG systems to Petrobras through its contracting partner EEP, to be equipped on four very large crude carriers (VLCCs).

The dual-fuel IGG systems can operate both on marine diesel oil / gas oil and natural gas, and they will be installed the four VLCCs which are being converted to FPSO vessels.

According to WTS, marine diesel oil or heavy fuel is burnt to produce inert gas with oxygen content of 2% to 4% and later the gas is entered into the scrubber part, where it is cooled and cleaned by sprayed seawater before being distributed to the deck area.

The company expects to deliver the eight dual-fuel units between December 2013 and September 2014.

"The equipment is designed to last for the lifetime of these vessels."

The IGG equipment will be installed onboard the vessels in the Estaleiro Inhauma dry-dock where the conversion of the VLCC hulls is scheduled to be carried out.

Following the conversion, the FPSOs will be operated in the deepwater pre-salt Santos Basin fields, 200km south of Rio de Janeiro.

Wilhelmsen Technical Solutions managing director of maritime protection, Steinar Andersen, said: "For Petrobras, the equipment is designed to last for the lifetime of these vessels and makes extensive use of stainless steel to ensure durability."

In May 2012, Petrobras signed a $1.7bn deal with a consortium of Brazilian industrial construction companies Odebrecht, OAS and UTC Engenharia for the hull conversion of a VLCC, as part of the plan to convert four VLCC carries vessels into four oil platforms; P-74, P-75, P-76 and P-77.
