MOTION ANALYSIS MARS TLP HULL

Project Summary

In 1995, the 14,500 t MARS TLP hull was transported from Taranto, Italy, to the Aker Gulf Marine yard in Corpus Christi, Texas, by the semi-submersible heavy-lift ship MIGHTY SERVANT 2. For the transportation of the hull, initially two possible configurations were studied:
1. TLP hull loaded straight onto the ship;
2. TLP hull loaded diagonally onto the ship (the configuration ultimately selected, see photograph below).

For the structural and fatigue analysis of the TLP hull, detailed ship motion responses were provided for a number of sea states and the full range of wave directions from head seas to stern seas.

■	Modeling of the TLP hull for the hydrodynamic analysis;
■	Merging of the TLP hull onto the heavy-lift ship in 2 configurations:

Mars TLP hull arrives on Mighty Servant 2

MARS TLP safely arrived on the MIGHTY SERVANT 2

■	Calculation of the motion/acceleration responses for a range of sea states/wave headings.

•	square stowage, with centerline TLP hull in line with centerline ship and all 4 columns overhanging;
•	diagonal stowage, with 2 columns on ship centerline and 2 columns overhanging;
