Overview

Olowi field development - inlet heaters and interstage heaters

Allards International Ltd undertook the thermal design, mechanical design, engineering, expediting, procurement, fabrication, and testing and inspection of the four inlet heaters, together with the two interstage Heaters - shell and tube heat exchangers.

These heat exchangers were designed for operation on the topside of the Fred Olsen Knock Allan FPSO, operating in the Olowi field in offshore Gabon.

Within a timeframe of less than eight months for supply, Allards International completed the ship motion and acceleration analysis, thermal and mechanical design followed by procurement and fabrication of the six heat exchangers.

The heat exchangers were supplied painted, ready for insulation to be applied on site. The company delivered the completed package, which was exported to Dubai in the United Arab Emirates for integration into the topside module.

The Olowi Field Development is a joint operation involving Fred Olsen Production a/s and CNR International. The heat exchangers were supplied to the Norwegian process systems company responsible for the development of the Knock Allan topside.
