Jumbo has just completed the shipment of the heaviest, tallest and the largest diameter Transition Pieces (TPs) the company has ever transported.

These TPs were shipped for client Jan De Nul Group in cooperation with brokers Multi Marine Chartering BV from Laem Chabang to Taichung, where they will form part of Taiwan’s Formosa 1 Phase 2 Offshore Wind Farm (OWF).

The Formosa 1 OWF will have a total capacity of 128MW once built and commissioned. Phase 1 of Formosa 1 features two Siemens 4MW demonstration turbines, the first ever wind turbines to be installed off Taiwan.

The Formosa 1 Phase 2 is owned by Formosa I Wind Power Co Ltd, a partnership of Ørsted (35%), JERA (32.5%), Macquarie Capital (25%), and Swancor Holding (7.5%).

In advance of the shipments, Jumbo coordinated the fabrication of 12 grillages which act as individual secure holdings on deck for each TP.  After installing the grillages on board Jumbo Kinetic, the vessel set sail to Laem Chabang to set the project in motion.

The TPs were carefully secured to the grillages on board the Jumbo Kinetic by her specialised team and then moved in three shipments from Laem Chabang to Taichung. In total 20 TPs with a diameter of 7.8m by 30m high and a weight of 462 tonnes each were shipped.

For this project, the Jumbo project manager, engineers, vessel manager, commercial, procurement, crewing, QHSE, technical departments, crew and port captains worked closely with the broker and our client to ensure the loading and discharge operations were successfully and safely executed on-time for all three shipments.

The added complexity of the height and weights of the TPs meant that smart and accurate logistical and operational planning and engineering were required.
