German Heavy Lift and Project Cargo specialists Hansa Heavy Lift, recently completed a project for the movement of subsea equipment for the Offshore Cape Three Points (OCTP) Integrated Oil & Gas Development Project located off the coast of Ghana in West Africa.
A total of four voyages were needed to complete the project using the HHL heavy lift vessels HHL Richards Bay and HHL Rhine. Each vessel shipped the cargo between the ports of Panama City, Florida; Nymo, Norway; and Takoradi, Ghana.
Hansa Heavy Lift Head of Americas Director, Steven Neuendorff said, “This was a challenging operation that required meticulous planning as well as operational flexibility by our marine crews,”
“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.
“To achieve this level of flexibility, efficient communication between key project personnel and marine crews was required throughout the project; from pre-planning to execution.”
This consignment of cargo comprised of Subsea Isolation Valves (SSIV), a horizontal carousel loaded with flexible products, vertical reels, a Flowline End Termination (FLET) sled, Steel Flying Leads (SFL) loaded on cassettes and various other subsea equipment.
Project Engineer for Hansa Heavy Lift, Tom Kroeger said about the project, “Due to the high amount of cargo units, crews had to overcome very tight stowage with precise positioning,”
“This was particularly the case for the 500-metric 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 load spreading.”
Kroeger added as everything had been prepared well in advance and due to strong cooperation with all parties, all engineering operations had run “particularly smoothly”.
Hansa Heavy Lift specializes in cargo classed as super heavy lift handling cargo over 900 metric tonnes and offers best-in-class engineering solutions with a strong focus on subsea, oil and gas, as well as the offshore wind farm sectors.
