(CIS) Extreme Conditions and Beach Landing
Heavy-lift specialist Mammoet has transported a cargo of vital compression equipment to the remote Sakhalin-2 project in Russia.
The challenging breakbulk project required delivery through extreme conditions to the east coast of Sakhalin Island in the Yuzhno-Sakhalinsk region.
“The initial schedule for the load-in to the island was 17 days, but Mammoet completed it in five. This successful execution helped us win additional scope for the installation of the three heaviest items at the OPFС site and transportation of the nine heaviest items to the installation area, so we are very happy with our efforts. We will now be able to adopt this same approach to projects with similar challenges in the future,” said Dmitry Matsiborko, project manager at Mammoet.
Onshore Processing Facility Compression
The delivery for one of the biggest oil and gas projects in the world include 22 pieces of equipment for the onshore processing facility compression (OPFC) site which could only be accessed by transportation barges passing through the volatile Sea of Okhotsk.
The remote island lacked a sheltered port capable of withstanding the weight of the gas production equipment creating further challenges for the move. To counter this, Mammoet devised a solution that involved a three-stage temporary beach landing.
“The beach landing had several special requirements. It needed to be strong enough to carry the weight of the load, with an added focus on stability to counteract the extreme wind and sea conditions. The nearest settlement was over 100 kilometers away, so the smallest details required extensive preparation,” Matsiborko added.
Temporary Beach Landing
To achieve the complex discharge procedure, each of the 22 items were individually transferred from the transportation barge to an intermediate barge and from there to the temporary beach landing facility and finally to the beach.
“The existing docking bay couldn’t withstand the 500-tonne three phase inlet separator, so it was built a 200-meter temporary beach landing facility, which for environmental reasons was dismantled after the execution of works so the beach could be fully restored to its initial condition,” Mammoet said in a statement
Headquartered in Schiedam in the Netherlands, Mammoet provides a range of services from transportation and logistics planning to heavy lift and crane rental.
