Seanamic Integrated Subsea Intervention Systems

With growing demand for deepwater well intervention, the offshore services industry is grappling with the competing demands of ever more challenging projects against a background of tighter budgets. The industry is ripe for innovation. Leaner, more integrated intervention systems that ‘raise the bar’ for subsea intervention performance and cost-of-ownership, are now offered by the Seanamic Group.

Specializing in surface to seabed systems, the Seanamic Group is headed by former Wellstream International Plc CEO, Alasdair MacDonald. “The technical challenges of deepwater intervention are well documented, not least of which is the cost of rigs and vessels to undertake this work. With budgets under scrutiny as never before, we anticipate significant market demand for integrated, lightweight portable systems, which will support deepwater fields facing increasingly complex issues—as opposed to one-off solutions. Our aim is to provide operators and contractors with these integrated systems.”

Surface to Seabed
The Seanamic Group comprises Houston-based, Umbilicals International (UI) and Scotland-based Caley Ocean Systems with further companies to join in due course. Formally HL Technologies, UI designs and manufactures custom dynamic thermoplastic subsea umbilicals and cables for harsh environments. Caley Ocean Systems has over 40 years offshore handling systems experience that includes deepwater lowering and IWOCS deployment systems, saturation diving and A-frame ROV and manned submersible LARS. Flexible, modular, high performance offshore handling systems are its trademark.

“There is a critical mass of maturing subsea wells and architecture in place, that is set to drive an increasing demand for well intervention services,” notes Gregor McPherson, sales director at Caley. “Portability, rapid mobilization and the ability to use vessels of opportunity have been the guiding principle of Caley handling systems for a number of years.”

According to MacDonald, setting the standard for surface to seabed systems is about offering a leaner, more integrated subsea intervention system. “Many companies talk about offering integrated systems but only at a fairly superficial level. Our aim is to drill down into the engineering to achieve unprecedented levels of integration that translate into industry-leading performance.”

Integration and Customization
Seanamics’ focus on manufacture and engineering gives it the edge. “Customization has long enabled the oil and gas industry to meet ever more demanding subsea challenges. Our proposition is that Seanamic looks at the client’s requirement from the surface to seabed as a whole, defining the level of customization required for optimum performance based on our knowledge and experience,” explains McPherson.

An example of Seanamic’s approach is its IWOCS deployment system, combining Caley’s engineering with UI’s umbilical design. Colin Zak, CEO, Umbilicals International, explains. “Working together with the client, we’re able to design and manufacture the umbilical and jumper so as to fully optimize the mechanical capability of the intervention deployment system and its performance subsea.”
