Conductor Installation Services Ltd (CIS), an Acteon company, has completed a complex pile-driving operation in conjunction with construction of a major gas production and processing development in Australasia. Working in the jungle, CIS performed a challenging series of pile-driving operations in order to form the foundations of three new bridges, a jetty and two wharves.

Five million man hours without a lost time incident

The CIS hammer services crew of four commenced the first phase of the pile-driving operation, which was associated with construction of two wharves on a river. With one of its 90 kJ hydraulic hammers located offshore on a barge in depths to eight meters (26 feet) and a second positioned onshore, the CIS crew operated the two hammers simultaneously. By doing so, CIS efficiently drove 12 x 48-inch abutment piles and 116 x 18-inch ground support piles to ensure that the new wharves would be built on solid foundations.

Following completion of the wharf pile-driving phase, CIS went on to drive 30 x 18-inch and 18 x 48-inch bridge support piles as part of the construction of three bridges. Once again, CIS drove the bridge support piles with pinpoint accuracy with the aid of surveyors and the hydraulic hammer on the piling crane. All piles were successfully driven to their specified target depths without a single Lost Time Incident (LTI). Overall, the companies working on the construction operation collectively contributed five million man hours throughout the duration of the operation.

A challenging operation

Operating for the first time in this particular area of Australasia, the operation proved to be a challenge. “This operation was unique, especially in view of the logistics of working simultaneously both offshore and onshore in the jungle,” said Andy Penman, Group Managing Director of CIS. “However, because we invested such a great deal of care and attention to the strategic planning process, the operation was carried out as planned. I also attribute our success to the reliability of our equipment, the experience of our crew and the excellent working relationship it shared with the customer and all parties involved. The fact that the entire operation was completed on time without a single LTI illustrates that safety continues to be a top priority,” he added.

To support the operation, CIS drew upon the technical expertise of its personnel located at the company’s base in Singapore.

The range of services provided by CIS supports the Acteon Group’s commitment to linking subsea services across a range of interconnected disciplines. CIS is a member of Acteon’s Conductors, Risers and Flowlines division.
