In 2007 personnel from Orwell Offshore, in conjunction with personnel from PDC Ltd and Smit International undertook the re-certification of the S2 saturation diving system prior to its deployment onto the MSV Havila Harmony for subsea completion work at the Puffin Field.

The scope of work included preparing as-built documentation for Class approval, identifying items which did not comply with statutory requirements and taking remedial action.

A number of personnel then followed the system offshore to assist with the diving operations.
