Marlim Sul Helideck Removal and Replacement
An oil tanker collision severely damaged the starboard aft side of the Marlim Sul, a floating production storage and off-loading vessel
owned by SBM Offshore. Harris Pye Engineering removed and replaced the helideck while the vessel was in production off the coast
of Brazil. The firm designed, fabricated, and installed the new helideck, as well as designed a temporary cradle and bumper for the new
pancake supplied by another company.
Harris Pye used a 3D scanner system together with Bentley Cloud Worx and Bentley Pointools to quickly gather information needed to
perform the work. The main structural design software used was STAAD.Pro. It allowed Harris Pye to quickly model the temporary cradle
and the part of the deck where it was installed, reducing time and costs for the USD 5 million project.
Innovation in Offshore Engineering
Guodian United Power Technology Co., Ltd. (United Power) launched an offshore energy utilization project to develop tidal current and wind
energy. The CNY 5. 3 billion Phase 1 includes an experimental prototype tidal current energy project off the coast of Zhoushan, Zhejiang,
China, and a wind turbine project offshore of Leting, Hebei, China. Preliminary planned capacity is 300 megawatts, and overall planned
capacity is 4,400 megawatts.
Guodian United Power used SACS to design the foundation and support structures. The three-pile jacket-type tidal current set weighed
700 tons. SACS performed modeling, hydrodynamic force calculation, and analysis of working conditions. For the six-pile jacket-type wind
turbine set, SACS performed strength analysis, modal analysis, and fatigue analysis. Calculations for 459 fatigue working conditions took
only 30 hours, saving labor and material costs.
