- 1. FEA AND HAND CALCULATION OF WERT, PLP, PARKING FRAME AND BANANA PLATE Strength analysis performed for various units, each with own purposes FMC Technologies awarded Rambøll to perform strength analysis of various units, such as WERT, Pig Loop Porch, Parking frame, Banana plate according to relevant standards. WERT: It is used for various configurations with different lengths and weights. Typical unit are Pig loop Porch (PLP), Triple Porch and Hogs configuration units. Evaluation of lifting for WERT with PLP structure was conducted for this particular unit, acc. to DNV 2.22 Lifting appliances. PLP: The scope of work for PLP structure was to analyze when subject to force during lifting, impact loading, landing during installation and stability against tipping in accordance with DNV 2.7-3 operational class R60 to achieve the requirement from NORSOK R002, which is the strictest criterion. Parking Frame: Parking frame are used for lifting/handling and transportation of WERT unit. There was six analysis considered and developed to understand the structural integrity of the unit. They are identified as follows: Evaluation of lifting Resistance of impact loading Transportation analysis sea fastening Forklift analysis of Parking Frame Stability against tipping Drop test analysis (Explicit Dynamic Analysis) Banana Plate: The Banana Plate has been designed by FMC Technology. The structure is a lifting device used for adjustment adjustment of sling used for the lifting of WERT and various configurations as Pig Loop Porch, Triple Porch and Hogs. The analysis performed for the banana plate consider the strength capacity of when subject connected between two slings Services provided FE Analysis with strength calculation in Mathcad.
