The Koso Kent Introl Subsea Team

The specialist team helping to solve increasingly tough subsea challenges

Subsea Oil & Gas production is a specialist subject by anyone’s standards. So when operators are designing processes that push the boundaries of previous experience, exploring options in deeper, colder and more distant fields - they want to talk to people who understand the challenges, and who can help to devise safe, effective valve solutions.

Under the direction of KKI’s Technical Director Dr Jonathan Lodge, a subsea expert himself for more than 25 years, the Koso Kent Introl subsea team is made up of such experts. Each brings not only knowledge of subsea valve solutions, but also a wider understanding of surface choke and control valve technologies. They are specialists in fluid dynamics and the regulation of flow and pressure. Their insights into life of field challenges, such as cavitation and erosion, are vital.

David Johnson
Choke Valve Business Manager

David heads up the subsea team and is a specialist in severe service subsea choke and control valve applications.

David’s career began as an apprentice at Blakeborough Valves. He gained his experience at Taylor Valves, Keystone Yarway, and Vetco Gray – as well as from two periods at Kent Introl totalling more than 15 years, where he now heads up the team responsible for both subsea and surface choke applications. His experience in an impressive array of subsea projects is invaluable to the team.

Jonathan Walker
Engineering Product Manager, Subsea

Jonathan has responsibility for the engineering management of all subsea commissions, including research and development, testing and qualification. Jonathan is also responsible for developing KKI’s IWOS solution (intervention work over system) in conjunction with KKI’s external running tool development partner, Subsea 7.

Jonathan’s working life began with a mechanical engineering apprenticeship at Hopkinsons. He also worked for Vetco Gray, Dril-Quip Europe and Aker Kvaerner in Aberdeen before returning to Yorkshire, first to Cameron and then to Kent Introl for a second time, in 2010.

Jonathan has a wealth of specialist experience that allows him to understand subsea system control processes from end-to-end; vital in his current role.

Simon Tattersall
Global Subsea Product Sales Manager

Simon manages KKI’s global subsea customer base, researching changing requirements and market demands. He is a technical specialist, contributing to solution design and liaising with customers during implementation, as well as providing aftermarket support.

Kent Introl is in Simon’s blood – he is the third generation of Tattersall to work at the firm. His career began with an apprenticeship in mechanical engineering, and he later joined Kent Introl in 1995, undertaking a number of roles.

A move to SPX Process Equipment was followed by a return to Kent Introl as severe service manager, before joining the subsea team.

Martin Lynn – Chief Applications Engineer

Martin has worked at Kent Introl since 1980. By the early 1990s, he helped develop subsea solutions, specifically with regards to actuators and PR2 testing. As the demand for deeper water applications grew, he also contributed to the design of tool retrievable options.

Today, Martin’s role is primarily in the preparation and execution of special testing procedures, covering pressure, fugitive emissions and flow capacity, including for Kent Introl’s recent 1 million-step PR2 test.

Preparing for the future

The team is looking ahead to the industry’s increasingly challenging demands: for intelligent well systems, electrically-operated subsea choke valves and subsea trees and the like.

But the most immediate need is to provide solutions that will help to extend the life of existing fields, focusing on aspects such as the subsea separation of oil, gas, water and sand.

KKI’s unique breadth of experience in surface choke and control valves translates into innovative solutions that seek to eliminate compromise within the wider application. For instance, the team’s expertise in developing trim technologies to manage greater pressure drops across chokes is of great benefit in this environment.

With a Senior Design Engineer under recruitment the team is now, more than ever, ready to tackle the increasing demands of operators.
