deugro Korea, in collaboration with its divisions in Japan and the UAE, has delivered 15,500 tonnes of subsea cables from Japan and Norway to a cable-laying vessel in Abu Dhabi.
deugro, against a strict project schedule, provided an all-in-one service solution for its client Samsung C&T (SCT). Altogether, deugro shipped 700 km of MRC, DC400 kV and FO cables, along with static tanks. deugro identified and chartered suitable heavy lift vessels capable of accommodating both the oversized static tanks and the high-volume cable consignments. The company managed ocean transportation and vessel inspections, coordinated all contract parties, and provided comprehensive scheduling and technical support. The project concluded with the successful delivery and dismantling of the static tanks.
“To start the installation process and minimise the overall cost of the project, the cables needed to be delivered quickly and on time. Scheduling, precise preparation and smooth project execution were therefore paramount,” said Jong-Yub Han, sales and business development manager operations at deugro Korea.
MRC cables, which measured 140 km, were loaded in a 20-day operation directly from a barge to the heavy lift vessel UHL Falcon at the port of Osaka, Japan. Tasked by the consignee, all requirements from the maritime warranty surveyor (MWS) were met on time so that the installation of tanks, the spooling operations, and a timely departure from the port were met.
“The biggest challenge arose from a short-notice requirement by the consignee’s MWS to record acceleration data during the sea voyage to the UAE,” added Han. “Since no measuring system was installed on the UHL Falcon, we quickly rented a motion monitoring system and had it hand-carried to Osaka for immediate installation on the vessel.” According to Han, deugro chartered UHL F-900 vessels for the following two shipments, which were already equipped with their own motion monitoring systems.
280 km of DC400 kV cable were spooled directly from the pier at the port of Hitachi in Japan, split evenly between the UHL Force and the UHL Fierce. The remaining 280 km of FO cable were collected by the heavy lift vessel BBC Austria from the port of Rognan, Norway. Two empty FO cable baskets had been loaded at the port of Finneid, Norway, and transported to the port of Rognan prior, where they were then spooled into the cable containers for final voyage to the UAE.
At Abu Dhabi port, the 140 km of MRC cable and 280 km of DC400 kV cable were transloaded via spooling from their respective vessels onto the installation vessel Isaac Newton, which – via the pier – was anchoring alongside. The 280 km of FO cable were unloaded by vessel crane, stored at the pier and later loaded onto the installation vessel using a mobile crane. Once all the cables were successfully delivered, the static tanks were disposed of at Abu Dhabi port.
Earlier this month, HLPFI reported that deugro had followed up its scope of work for Ineos Project One.
