On 2 Jan 2014, Divetech Marine announced the successful underwater and surface reinstallation of six Rolls-Royce azimuth thrusters on Transocean's Deepwater Millennium drillship in Singapore.
Divers and coordinators from Divetech Marine liaised closely with Transocean's thruster manager and staff from Kim Heng Marine and Offshore to secure and reinstall six Rolls-Royce azimuth thrusters.
Divers from Divetech Marine rigged and connected strand jack anchors in the water and on deck for the refurbished azimuth Rolls-Royce thrusters to facilitate the reinstallation process.
Despite currents of up to 3 knots at Raffles Reserved Anchorage, divers remained in the water with the help of magnets and monitored the reeling in of strand jack anchor wires to ensure that the thruster lifting process was without hiccups. After thrusters were installed, divers then disconnected the strand jack anchors.
Divers also conducted in-water video inspection on the all thruster seating rings, O-rings, as well as sealant compounds to ensure that no obstructions were in way of these thrusters that might compromise their performance.
For increased safety of divers, two separate sets of air panels, air banks and five KMB bandmasks mounted with CCTV cameras and underwater lights were prepared on site to ensure that divers could perform non-decompression dives with minimal risk of decompression sickness. Having two sets of equipment also allowed for diving operations to be carried out continuously without any loss of time to the client.
