Island Patriot Undergoes Thruster Upgrade And 10 Year Vessel Class Survey


As a part of StimWell’s dedication to the continuous improvement of the vessel and its systems, the Island Patriot has seen a number of improvements since her introduction in 2010. The most notable of these improvements were undertaken during the vessel’s scheduled docking in the Fayard Shipyard in Odense in July of 2015, where a bulbous bow and additional bow tunnel thruster were installed.

The bulbous bow, which was prefabricated by Fayard A/S, was designed and constructed to replace the existing bulb and accommodate the additional tunnel thruster.

The installation of the additional bow tunnel thruster raises the vessel’s Environmental Regularity Number (ERN) to 99/99/99/98, resulting in a marked improvement in station keeping abilities (refer to table). The upgrade enforces the vessel’s capability of operating in the toughest conditions, offering our clients the benefit of a significant reduction in non-productive time.

Following dry dock, and as a part of StimWell’s Management of Change Process, the vessel went through a rigorous Testing and Commissioning Programme. The project was considered a resounding success by all involved, with the first successful treatment post dry dock being completed in early September of 2015.


In addition to the thruster upgrade, the following key additions /modifications were made to the vessel while in dry dock:

  • Addition of a 7th SPM TWS 2250 high pressure frac pump (skid mounted for additional flexibility), providing 14,000* HHP and 15,000** psi working pressure
  • Installation of a new, purpose built, fully integrated, GOES fracturing control system
  • 10 year vessel class survey and certification
  • Installation of a RO process plant capable of generating 20 m3 of fresh water per day, allowing for more stimulation materials to be carried
