Mammoet-Giant move 333 pin piles for Greater Changhua 1 & 2a OWFs
Mammoet-Giant Taiwan has been going full speed ahead with its scope of work on the Greater Changhua 1 & 2a offshore wind farms. Besides currently transporting 333 pin piles for the project, the joint venture is also supporting Heerema Marine Contractors (HMC) with the load-in and load-out of equipment and supplies for the working vessel: transport and temporary storage for offshore equipment and maintenance of the two pin pile hammer heads, weighing 700 ton each.
Currently over a year and half into heavy transportation work, the team is ensuring all pin piles are transported on time to meet the target dates for HMC, despite having to face weather disruptions. The team has overcome this challenge by increasing the wind speed limitation of the crane and by setting flexibility in work hours, adhering to the international offshore wind standards of Quality, Health, Safety and Environment.
An increase in wind speed limitation helps to create a longer window of time for each load-out operation. This enables efficient use of available time to transport the maximum amount of pin piles within a given period.
Mammoet’s team has adjusted the working times being used throughout the project so far, to complete the work flexibly while ensuring the morale of the team stays positive. As such, Mammoet has been able to ensure that all pin piles have been delivered on time and meet the customer’s target dates.
An element of sustainability is also factored into this project. Specifically, the team is using a paperless system to record all required aspects of safety-related issues, e.g. toolbox briefings, training records and pre-operations daily checks.
For example, this paperless system allows the team to save up to around 20 pages of A4 paper, which would otherwise be used for daily toolbox briefings and pre-checks of on-site equipment. This approach further provides efficiency for the customer as staff are now able to review the records at any time.
Mammoet-Giant has been working on this project since mid-2020 and is expected to complete all heavy transportation work by the end of 2022. The Greater Changhua 1 & 2a Offshore Wind Farms are Taiwan’s first large-scale projects of their type. The wind power generated will have an installed capacity of 900 MW once completed and will be enough to provide clean energy to one million households in Taiwan.
