Heavylift / Breakbulk
A juggernaut sails the high seas
A 91 m and 880 t splitter destined for a Mexican refinery was recently shipped out of the Indian port of Mumbai. Comprehensive extra measures needed to be taken to ensure the smooth management of the multimodal transport task. A special vehicle concept designed for the transportation of heavylift shipments proved to be rather helpful in the process.
Exceptional freight consignments are regularly shipped through the Indian port of Mumbai. This year the country’s most important maritime hub saw yet another heavylift task carried out, when an overly-long splitter destined for a refinery in Mexico was handled in the hub. The project was organised by Boxco Logistics, and saw the use of a Scheuerle-Kamag K25 self-propelled modular vehicle.
The journey started at the manufacturing plant of Isgec Heavy Engineering (formerly the Indian Sugar and General Engineering Corporation), in the industrial town of Dahej in the state of Gujarat in western India. Transporting the splitter, which weighed in at an impressive 880 t, had to be managed together with the haulage of a 380 t quench water tower and a 250 t demethaniser, along with all of their accessories.
The transportation of the columns from the Isgec plant to the port of Adani was a challenge, as the splitter measured 91 x 9.5 x 9 m. Various civil works measures were required, such as the widening of certain roads and removing obstacles, including dividers and light poles. These were naturally carried out prior to the commencement of the transportation task proper.
Electrical line shutdowns were arranged with the local electricity boards. The transportation was carried out in just four days, in coordination with the local police forces. The entrance wall to the port of Adani had to be razed, in order to allow the convoy onto the premises. On-site transportation at the port, especially of the 91 m splitter, also posed quite a challenge, due to narrow passages.
The schedule for the shipment of the equipment from Dahej came on the verge of the monsoon rainy season. The derrick barge Triton Vision, towed by the 30 t bollard pull MT Canara Progress, was chosen to complete the task of sea transportation from the waters of the Narmada river delta in the Gulf of Khambat to the port of Mumbai. After engineering the required stowage plan, executing the jetty civil works and ramp construction the barge arrived at Dahej jetty under tow by smaller tugs, due to low draft conditions in the Narmada basin. After stowage of the cargo, sea fastening was carried as per the pre-calculated procedures.
To Mumbai by bollard pull barge
Once the cargo and fastenings had been surveyed, the barge loaded with the refinery equipment was hauled by the smaller tugs to the Dahej anchorage, where it was handed over to the MT Canara Progress. The vessel then transported the loaded barge up to the port of Mumbai. Upon arrival and alignment of the barge at Mumbai, delashing was carried out based on the works and rigging plan. The Scheuerle-Kamag K25s deployed at Dahej were also used to successfully carry out the roll-off operations at Mumbai port. The Roll Dock Sea arrived at Mumbai to load the columns on board.
The two smaller columns were lifted on board by the vessel hook, but the splitter was too large and heavy for the same procedure. A feasible option was to roll the column on to the ship using the Scheuerle-Kamag K25 self-propelled modular transporter.
