Thome Offshore and Tasik Toba Subsea have jointly won Offshore Support Journal’s Safety Award for 2021 for their work in achieving the world’s first Infectious Disease Mitigation-Arrangement (IDM-A) notation from ABS
The notation was awarded to dive support vessel (DSV) Southern Star. Achieving the IDM-A notation was the result of months of collaborative efforts between the ship manager and shipowner together with charterer Shelf Subsea, to ensure the vessel complied with detailed engineering and procedural requirements for the management of infectious diseases, including Covid-19. These arrangements are designed to prevent infectious diseases entering the vessel, to contain any disease in the event of an outbreak, and to have contingency plans in place to evacuate any serious cases for treatment.
The engineering controls included installing a dedicated isolation facility, modifying the HVAC system and exhaust air routes, changing sink taps to hands free and segregating the citadel by transmission-proof doors. Procedural controls included a ship-specific outbreak management plan, and strict controls on quarantining and testing for joining and departing crews.
Accepting the award at an in-person ceremony at the Annual Offshore Support Journal Conference in London, Thome Group business development manager Torbjørn Lie said, “Becoming the first vessel in the world to achieve this infectious disease mitigation notation from ABS demonstrated a clear commitment to the safety of our crew and other stakeholders. I am really pleased that the hard work and close collaboration by both companies has been recognised with this award from OSJ.”
Also present at the ceremony was Tasik founder and chief executive John Giddens, who commented, “Winning the OSJ safety award is the icing on the cake for the teams that were involved in developing the procedures, plans and documentation needed to gain this class notation. The collaboration between Thome and Tasik has given confidence to all those interested parties that the highest possible standards of safety are being maintained, above and beyond any national and regional requirements.”
Southern Star has recently been undertaking subsea construction work on the Thai-Malaysian border with Shelf Subsea and maintained incident and Covid-free operations. The vessel will shortly mobilise for subsea work in Myanmar.
The DSV boasts DP-3 dynamic positioning systems, 300-msw saturation diving system, twin air diving systems, two remotely operated vehicles and a 150-tonne SWL active heave-compensated subsea crane, with 120 on board.
“The implications of an onboard outbreak of an infectious disease on any vessel are a real and present threat,” said Mr Giddens. “For a ship with divers who may be confined for weeks at time in a high-pressure environment, the potential problems are exponentially magnified.”
