ZPMC Crane Services has completed a tricky project that required it to modify and deliver two cranes from Charleston, SC to Saint John, New Brunswick in 60 days.
ZPMC Crane Services, the U.S. service division of ZPMC North America Inc. completed the 60- day contract in just 45 working days. According to ZPMC Crane Service’s Regional Vice President Ed Johnston, ZPMC’s global fleet was a key element that made the project possible.
“DP World recently executed a 35-year agreement with the Port of Saint John that required the delivery of two additional STS cranes ready to go to work January 14, 2017,” said Johnston. “DP World located suitable cranes in Charleston, SC that were on the market. Coincidentally, our team had delivered these cranes when they were new in 1998 and had installed articulating bogies on them in 2004, so we were already familiar with them.”
The scope of work DP World required included weighing the cranes, installing new cab washing platforms, removing waterside spacers from the legs to accommodate the new dock elevations, machining the gantry wheels to match their rails and delivery to Saint John, New Brunswick, Canada.
The contract was awarded on August 31, with work scheduled to take place over September and October, which timed with the availability of ZPMC’s ship Zhen Hua 14, which was scheduled to offload new cranes in Charleston. “When bidding the job, one major advantage we could offer was the ability to utilise ZPMC’s own ship that could handle the extreme 28-foot tides in the Bay of Fundy,” said Johnston.
The crane modifications were competed in Charleston prior to loading, with the Zhen Hua 14 standing by. On October 7, five weeks into the project, the Zhen Hua 14 was ordered out to sea to take it out of the path of Hurricane Matthew, idling the project for 10 days until the ship could return. Despite the set back, Johnston’s crew loaded and sea-fastened the cranes, made the six-day trip to New Brunswick, and offloaded the first crane on November 1.
Saint John’s massive tides meant unloading had to be competed very quickly. The first crane was offloaded on a rising tide in 35 minutes using the ship’s specialised gear,”and the second in only 28 minutes. The cranes are scheduled to go into service on January 14, 2017.
“STS crane relocations are complex projects, demanding the highest levels of technical expertise and team work,” said DP World’s Manager, Engineering & Maintenance Joel Werner. “Modifying these existing cranes, together with safely relocating them, was a critical component to the successful startup of operations in Saint John. ZPMC Crane Services demonstrated an excellent understanding of the critical technical considerations and delivered the cranes safely within the required timeline. The depth of knowledge and ability to overcome challenges was demonstrated many times by Ed Johnston and the ZPMC team.”
