Hansa Heavy Lift has moved subsea equipment to assist with the development of the Offshore Cape Three Points (OCTP) Integrated Oil & Gas Development Project off the coast of Ghana.
The consignments included vertical reels, a horizontal carousel loaded with flexible products, Steel Flying Leads (SFL) loaded on cassettes, a Flowline End Termination (FLET) sled, Subsea Isolation Valves (SSIV), and a variety of other subsea equipment.
The task involved mutliple voyages for the shipping line's heavy lift ships, HHL Rhine and HHL Richards Bay, which transported the cargo between the ports of Panama City, Florida; Nymo, Norway; and Takoradi, Ghana.
The first voyage included multiple reels and a carousel, all loaded with umbilicals and flying leads, which were transported from Panama City to Takoradi onboard HHL Richards Bay.
One of the HHL Rhine's voyages saw it carry subsea hardware from a facility in Eydehavn, Norway with the cargo discharged in Takoradi.
HHL Richards Bay undertook two other voyages, one returning empty reels and other miscellaneous equipment from Takoradi to Panama City; the other included more reels loaded with umbilical products transported from Panama City to Takoradi.
Tom Kroeger, project engineer, Hansa Heavy Lift explained that the large number of consignments meant that the ships' crews had to overcome very tight stowage with precise positioning. "This was particularly the case for the 500-tonne carousel on deck, which needed to be stored in a specific position to cover all supporting girders of the hatch cover to ensure sufficient loadspreading."
"This was a challenging operation that required meticulous planning as well as operational flexibility by our marine crews," said Steven Neuendorff, director, Head of Americas, Hansa Heavy Lift. "We had to accommodate changes in the loading and discharge sequence, and to the offshore installation sequence in order to meet the customer's specific requirements.
