Posted on 09.09.2016 - 14:37 EDT in PRODUCT NEWS by DT_Amanda

•       The world’s leading mass flow excavation provider has launched the SP12000 as part of its range
•       SP12000 is the world’s most powerful hydraulically-driven mass flow excavator
•       Tool will be operated for clients by an expert team on large scale excavations utilising the same precision capabilities as its other market-leading tools

The world’s leading mass flow excavation business, James Fisher Subsea Excavation – part of James Fisher and Sons plc, has brought the world’s most powerful tool to the market to support clients with large scale excavations.
The SP12000 produces more than 6 tonnes of thrust at full power and a significant volume output of 12,000 litres of water per second, making it ideal for large seabed preparation projects, sandwave clearances, freespan rectifications and large diameter pipeline trenching.
James Fisher Subsea Excavation’s expert team, who have the most in-depth knowledge and understanding of mass flow excavation worldwide, recently completed an extensive re-engineering project on the SP12000. Advanced hydrodynamics and improved efficiency have been combined to give an excellent flow regime, which produces the cleanest cut trench possible by a mass or controlled flow excavator. Despite its size, the fully-controllable SP12000 is also capable of smaller-scale, precision excavation.
This new technology is also being applied to the company’s existing extensive fleet of mass flow excavators, also known as controlled flow excavators, around the world.
Graham Murdoch, technical director of James Fisher Subsea Excavation, is part of a team that has been responsible for the successful completion of more than 400 projects over a period of 18 years. He said:
“We already had the most diverse and well-proven range of mass flow excavators available. Adding the SP12000 to our range means we can support our clients on an even wider range of projects. The ability to match different tools to any given workscope allows us to provide the most time and cost-effective solutions available for projects worldwide.
“The SP12000 is a massive step forward in mass, or controlled, flow excavation. It has immense power with the capability to provide large-scale clearance and trenching, but it retains the precision and controllability to be as safe and exact as our other market-leading tools. This is a real game changer for our clients who have large-scale requirements.
“The technological advances we have developed during this engineering phase have already started to be transferred to our other excavators with the benefits being realised on recent projects for our clients.
“James Fisher Subsea Excavation has brought together the mass flow excavation industry’s most experienced personnel, from those operating and maintaining the tools, through to the office-based engineering and support staff to our senior management team. We have a proven track record of using our in-depth knowledge, expertise and innovative approach to address the needs of our clients and deliver the strongest results thanks to our stringent standards.”
James Fisher Subsea Excavation’s fleet of tools provide a non-contact form of excavation that eliminates the risks associated with other excavation methods, especially around complex subsea assets. Further enhancing its capability, the tools have the additional benefit of real-time sonar imaging, enabling precision excavation in confined areas, as well as for large cable or pipeline scopes.
James Fisher Subsea Excavation has a total of 28 spreads which, alongside the SP12000, include the established ‘T’ tools, the innovative TwinProp and the SP single prop range. This represents the largest and most diverse fleet of mass or controlled flow excavators in the world, which ensures customers are provided with a tailored solution to their project requirements. It operates from strategic hubs in the UK, UAE, Singapore, Venezuela, USA, Brazil, South Africa, China and Mexico.
James Fisher Subsea Excavation’s equipment is used for applications including pipeline and cable trenching, deburial, rock dump dispersal and seabed clearance and preparations. The mass flow excavators are ideal for moving materials such as sand, silt and mud, drill cuttings, clay and rock dump.
