At the beginning of 2005, Modec Tokyo (www.modec.com) commissioned Resinex to supply two Pem 21 x 2550 deep-water buoys for the Bongkot FSO2 project in Thailand. The buoys with 4,300 kg net buoyancy and 75 metres of operational depth were studied by Resinex for offshore high pressure resistance and high hydrodynamics.
The double countering cone-shaped form which was chosen enabled the satisfying of both requested requirements.
