Crane Pedestal Grillage Design and Engineering By TWD for Jack-Up Barge

Jack-Up Barge’s JB 117 platform is currently working off the West African coast of Northern Senegal.

Before leaving Rotterdam for Senegal in November last year the jack-up crane platform was fitted with a crane pedestal grillage designed and engineered by TWD.

The TWD Team conducted a wide range of analyses including critical structure fatigue analysis and stability analysis of underdeck structure to ensure safe operations of the crane. Based on the result of the analysis, TWD delivered an ingenious design of grillage that allows relocation of crane pedestal on deck.

The JB-117 is a MSC SEA-3250 self-elevating unit and built in 2011. It’s registered with ABS. The leg length is 80m and has a maximum pay load of 2,000t and in addition has a crane capacity of 1,000t.
