Pile-driving specialist gears up in nearshore marine construction industry
CIS, an Acteon company that installs conductors and piles for the oil and gas and nearshore marine construction industries, announced that it has completed a major pile-driving operation in conjunction with construction of a new $240 million state-of-the-art phosphates terminal in Jordan. The terminal is purpose-built to export and handle upwards of six million tonnes of rock phosphate in bulk annually. It is located in the South Port section of the New Port of Aqaba, and features storage facilities, off-loading systems and handling and ship-loading equipment.
CIS performed a series of pile-driving operations to form the foundations of the new terminal, which features a new dry bulk export jetty, and dust and spillage control facilities. The storage plant, load transfer building, and berthing maritime terminal for exporting phosphates are located onshore. Offshore, the complex is comprised of a 190m-piloted berthing area with two parallel-to-coastline structures that support two loading bays, two mooring dolphins, an access bridge and two bridges that connect the structures.
Working nearshore poses unique challenges
With one of its S-150 hydraulic hammers situated offshore on a crane barge in depths of up to 23 meters (75.45 feet) and a second positioned onshore, the CIS crew operated the two hammers simultaneously. As a result, 16 piles measuring Ø914mm (36 inches) were driven to a maximum penetration of 25 metres (85.02 feet) to ensure that the essential onshore facilities would be built on solid foundations.
Following completion of the pile-driving phase carried out as part of the construction of the onshore portion of the jetty approach, CIS began working on the offshore construction phase. This involved driving 149 jetty support piles measuring Ø914mm (36 inches) as part of the construction of berthing structure and three bridges. Again, CIS drove the jetty support piles with pinpoint accuracy with the aid of surveyors and the hydraulic hammer on the piling crane. Every pile was safely driven to its intended target depth without incurring a single Lost Time Incident (LTI). All 165 piles were driven safely and efficiently, well within the requisite timeframe for completion.
Keys to success
Operating for the first time in Jordan, the operational aspects of the job were challenging. “The logistics of working simultaneously onshore and offshore was in and of itself a challenge, compounded by the extremely high temperatures in Jordan. To address this, our engineers dedicated a great deal of time to developing a highly detailed pile-driving plan, with complete guidance on coordinating the onshore team with the crane barge. This detailed plan was finalised well in advance of the scheduled start date, paving the way for completing the job on schedule,” said James Chadd, Managing Director of CIS.
“The success of the operation should also be attributed to the experience of our crew and its meticulous attention to executing that plan to the letter. Plus, maintaining clear communications with the customer and all parties involved. The entire operation was completed on time without a single LTI and this illustrates our ability to work safely and efficiently. We look forward to executing many more pile-driving operations, as we gear up to expand our activities in this dynamic and challenging market,” he added.
To support the operation, CIS drew upon the expertise of its personnel and state-of-the-art hammer equipment based at the company's global headquarters in Great Yarmouth, England.
CIS, an Acteon Company, provides pile and conductor installation services associated with construction projects for the nearshore marine and civil markets, and oil and gas industry, respectively. Founded in Great Yarmouth, England in 2005, CIS has built an impressive track record of successful operations carried out around the world. Since then, CIS has not incurred a single lost time incident (LTI). CIS has been awarded the Gold Medal for Occupation Health and Safety for 10 consecutive years, resulting in a President's Award from the Royal Society for the Prevention of Accidents (RoSPA) in 2019. It is the highest award for safety in the United Kingdom. Learn more at www.c-i-services.com.
Acteon solutions for marine construction
Acteon customer-focused solutions offer a high degree of flexibility, exceptional service quality, and fresh thinking across the life of a field, from marine renewables, marine construction, asset integrity and decommissioning. Each solution may be based on complete pre-packaged integrated services or combined elements from more than one existing or bespoke integrated service. To reduce the total cost of ownership of critical marine and subsea infrastructure across the lifecycle of projects, the Acteon field life service team typically project manages integrated services that address complex challenges by combining a wide range of Acteon and third-party expertise. They are often offered on innovative commercial terms, which may share risk and reward.
For Marine Construction, Acteon installs marine structures from the seabed to surface across civil (for example, ports, harbours, jetties, bridges, masts and beacons) and resource (LNG, metals, minerals) markets. The integrated service also features site survey and investigation to marine civil structure construction, including full foundation “design and install” to operations and maintenance asset integrity offerings, such as structural and cathodic protection monitoring, marine growth control and seabed surveys.
Acteon provides a range of industry-leading products and services supplied by its operating companies to support subsea projects during any phase of the life of a field; solutions that create and manage the delivery of fully integrated services to answer complex, customer-specific challenges of any scale or complexity; and strategic innovations that answer unmet long-term or industry-wide needs. The Acteon field life service team delivers Acteon solutions and strategic innovations in collaboration with customers and partners through conventional or new commercial models.
