PACC Offshore Services Holdings (POSH) reported its semi-submersible accommodation crane vessel CIMC Gretha successfully completed its annual survey, five-year FMEA proving trial and load test of offshore mast cranes in Singapore
Commenting on the certification on social media, POSH said the “significant feat” was completed safely and ahead of schedule “thanks to the support of our POSH crew, owner representatives OC/CIMC, class surveyors ABS and MWS Aqualis, third-party service providers and contractors.”
“After years of operating at a maximum capacity of 600 tonnes, our two Huisman offshore mast cranes (OMCs) are now certified to carry [their] full capacity of up to 1,800 tonnes. This notable milestone follows the rejuvenation of CIMC Gretha’s thrusters last year, which was one of the industry’s largest maintenance projects,” wrote POSH.
Built in 2012, CIMC Gretha underwent the overhaul of its six massive 3,800-kW Thrustmaster TH5000ML azimuth thrusters in Curacao in 2020. The maintenance was complicated by lockdowns in Curacao due to Covid-19. Supported by owner representatives from Ocean Challenger and POSH crew on board the vessel, the work involved divers, technicians and engineers from CIMC Raffles, Stone Marine UK and Subsea Global Solutions Caribbean.
The DP3 semi-submersible accommodation crane vessel has a length overall of 138 m, beam of 81 m, deck space of 2,000 m2 and deck strength of 10 tonnes/m2. With its two Huisman OMC cranes- which have a tandem lift capacity of 3,600 tonnes, dynamic positioning class 3 capabilities and accommodation for 618 in single- and two-person cabins, CIMC Gretha is designed for decommissioning and heavy construction activities.
DP technology and testing will be discussed in depth during Riviera’s European Dynamic Positioning Conference virtual event on 24 March 2021 - use this link for more details and to register for this virtual conference
