Capacity enhancement for deep water operations ENGINEERING SOLUTIONS AND CAPABILITIES THE CHALLENGE THE SOLUTION Operations are taking place in much deeper waters and in more diverse locations, Aquatic built a 50te tensioner (AQTT-10E-50 DUAL) that can be used individually or and when umbilicals or cables are deployed in deeper water, the holdback tensions paired with another 50te tensioner to achieve almost double the capacity of a single generated are much greater than in more shallow sites. tensioner. The dual tensioner system has a special manifold which was developed to Technip Norge AS contacted us to see if we had a tensioner for hire with 85Te outboard tension capabilities. Our response was to explore an innovative approach and so Aquatic s in-house specialist engineering team quickly identified that it would be possible to design a solution that combined two 50 tonne tensioners. allow two machines to work in tandem. It operates from a single power pack which provides hydraulic power into the tensioners equally through this manifold, taking multiple inlets or outlets into one. The manifold diverts the hydraulic fluid into two equal streams so that both tensioners operate at the same flow rate and pressure., ensuring a fully balanced operation. www.aquaticsubsea.com
THE OUTCOME Working closely with Technip to fully understand their needs, Aquatic was able to develop an innovative piece of equipment in response to a commercial need. The client was involved with the testing, both at Aquatic s operational facility in Peterhead and on its own vessel in France. As with all Aquatic s equipment fleet, the modular nature of the AQTT-10E-50 DUAL s design enables it to be broken down very simply into component pieces and packed inside a standard container for transportation by road and/or sea. AQUATIC TECHNIP Aquatic, an Acteon company, continues to develop a strong global reputation for its ability to lay flexible and semi-rigid product on the seabed. With wide experience of off- and onshore installations, transpooling and recovery and decommissioning, Aquatic develops and leverages innovative technology to extend its capabilities to match clients expectations.

Subsea installation services in the South China Sea INVENTORY AND SKILLED RESOURCE IN THE ASIA PACIFIC REGION THE OPPORTUNITY THE PROJECT Aquatic Asia Pacific Pte Ltd successfully tendered to provide services for installation contractor China Offshore Oil Engineering Co. Ltd, the company s first Contract with COOEC. The project took place in the Lufeng and Panyu oilfields, South China Sea for a period of two months, completing in August 2012. The equipment hired from Aquatic was the AQPR-02C-290Te reel hub drive system and the AQTT-10B-40Te four-track tensioner system. Aquatic Asia Pacific has its own fleet of equipment mobilising out of Loyang yard, Singapore making it cost effective and timely for clients in the Asia Pacific region. The project was a typical offshore flowline of 300mm O/D and 447mm O/D and riser installation; Aquatic supplied offshore personnel as well as the equipment for deploying the flexible riser on board the Nanhai Sheng Kai floating, storage and offloading unit (FSOU). This FSOU has been in service since 1992, well beyond its planned 12-year life-span and the field s operator, China National Offshore Oil Corporation Ltd (CNOOC) is extending the FSOU s operational life by another 15 years by upgrading and relocating its mooring system to the Lufeng oilfield. www.aquaticsubsea.com
THE PROJECT (CONTINUED) THE OUTCOME The subsea installation phase of the project finished ahead of schedule due to the The negotiations that took place prior to the project, combined with the positive reliability of Aquatic s equipment and the expertise of Aquatic s personnel. Also feedback Aquatic received following its completion, demonstrates that Aquatic has involved in this project with Aquatic were Acteon sister-companies InterMoor, who begun a new and positive relationship with a key Chinese customer. provided all mooring related activities, Offshore Installation Services, who provided vessel management support and offshore personnel; and 2H Offshore who provided riser installation engineering. The overall project also finished ahead of schedule due to the experience of the teams involved. This project is seen as a further re-inforcement of the strategic aspirations Aquatic has for the Asia Pacific region, as the global development and growth of the business moves apace. UNRIVALLED EXPERIENCE Aquatic is globally renowned for laying and retrieving flexible and semi-rigid products on while Aquatic s own extensive range of equipment includes powered-reel drive systems, the seabed and has proven ability in shallow and deep water, and extensive experience tensioners and storage reels. This kit is modular in design, making it highly flexible, of off- and onshore installations, transpooling, recovery and decommissioning. From able to be dismantled and easily transported by road or sea in standard containers to its custom-built workshop and yard facility, clients are offered a complete storage, anywhere in the world; for clients this means faster, more cost-effective mobilisation inspection and management service for spare pipeline and umbilical products and reels and demobilisation, an essential component of success for any commercial project.

Umbilical engineering and installation PROVIDING TAILORED SOLUTIONS BASED ON THE UNIQUE REQUIREMENT OF OUR CLIENTS THE CHALLENGE THE SOLUTION Aquatic had bid on providing a tensioner and powered reel drive system for an Aquatic arranged for a sample 10m of the umbilical product to be sent to its specialist umbilical installation off the north-west coast of Angola. There was a question raised operations facility at Peterhead, UK and tested it on the specified two-track tensioner. by Aquatic, just prior to mobilisation, over the original customer lay analysis. Did It looked as if the flexible product, being fragile in nature and yet heavy in payload, the precise coefficient friction for the flexible product being used for equipment to would deform on this equipment. The pull tests also imitated the ocean conditions support the umbilical installation actually match the detailed report from the umbilical of the South Atlantic. By refining the lay analysis, a four-track tensioner was swiftly manufacturer? Discovering last minute information is a common issue that can arise requisitioned from a forth-coming project, which then replaced the originally preferred when there is a considerable time period between requests for tender, bid and project two-track tensioner. execution. www.aquaticsubsea.com
THE OUTCOME Aquatic s attention to detail and experience in project management meant that this key issue which could have resulted in additional delay and therefore cost to the client, was detected prior to mobilisation. The correct equipment was sent to offshore Angola and then returned to Peterhead to be serviced, before being sent out for its next planned booking. Aquatic s diligence and logistical ability enabled two clients to receive the same piece of kit, without compromising either project. The team successfully avoided project delays on the umbilical installation, that would otherwise have gone awry. UNRIVALLED EXPERIENCE Aquatic is globally renowned for laying and retrieving flexible and semi-rigid products on the seabed and has proven ability in shallow and deep water, and extensive experience of off- and onshore installations, transpooling, recovery and decommissioning. From its custom-built workshop and yard facility, clients are offered a complete storage, inspection and management service for spare pipeline and umbilical products and reels while Aquatic s own extensive range of equipment includes powered-reel drive systems, tensioners and storage reels.
