As part of construction work at the Puffin Field, the project needed an HRV – Hyperbaric Rescue Vessel – to act as standby vessel to the DSV Havila Harmony during the tie-in work.

Prior to start up, the vessel additionally was to be fitted with an ROV to provide further subsea work capability during the final testing and commissioning of the wells.

Naval Architects from Orwell Offshore undertook the design modifications to the vessel to accommodate the ROV deck (originally designed and installed on the Pacific Worker). They designed a static A-Frame which could be used in conjunction with the onboard winches to recover the hyperbaric rescue chamber in the event of an emergency.
