Key Personnel
Pierre Guerin
Director, France
About
Pierre is the director of the 2H France office. He is based in the south of France and splits his time between there and Paris. He is responsible for management of the Paris office and global growth of the company’s engineering services for the renewable energy sector. Guerin came to 2H in April 2021 with over 20 years’ experience in marine renewable energy, in particular, offshore wind, shipbuilding and oil and gas. Most recently he spent 5 years managing the development of renewable energy projects for Bardot Ocean. He also has an impressive 10-year track record of regional and international expansion projects from Principia where he focused on floating structures, coastal and naval defence engineering.

Pete Simpson
Director, Brazil
About
Pete is currently the director of 2H Offshore’s office in Rio de Janeiro, Brazil. Pete graduated with first-class honours in mechanical engineering from Cardiff University, UK, and joined 2H in 2002. After two years working at 2H’s office in Woking, he spent a year working as part of a 2H team within Saipem’s offices in Paris on the Kizomba B Project and then moved to Brazil in October 2005. During his time at 2H, he has developed extensive experience in freestanding riser systems in the Kizomba B project, SCRs on the P-55 FEED and also on the BSR system installed by Subsea7 in the Sapinhoá and Lula-NE fields offshore Brazil. He shares the management of the 2H office in Brazil with technical manager Roberto Alvim.

Seawater cooling systems are a technology being using in offshore energy production to improve power generation and reduce emissions. They will reduce up to 90% of CO2 emissions for air conditioning and up to 25% for electricity production for fossil fuel power units.
2H is currently applying its extensive experiences in risers and pipelines to design sea water intake solutions that cool down power units generation and significantly reducing CO2 emissions. The technology is based on steel or polymer risers bringing sea water from deep sea to the surface power unit. Water is used to replace the air cooling of the production system. Deep sea water captured is between 5°C to 15°C at water depths of up to 1000m. The performance of the cooling unit increases in ultradeep water.
