In the Splash Zone environment, typically +/- 20 meters above or below sea level, (IRM) inspection, repair & maintenance services, have traditionally relied on vessel based, ROV or Diver supported operations. While these types of operations are generally carried out quite successfully in the subsea sector, they have proved difficult, if not impossible in the splash zone, where the effect of strong wind and wave and tidal conditions make traditional subsea techniques generally impractical. The core business of Ocean Tech is to operate Splash Zone ready tools and techniques, many using standard ROV tools & tooling, deployed from stable work platforms in the splash zone, using T4 Schilling robotic ROV arms, as found on most work class ROV’s.

This presentation will demonstrate the types of operation currently being carried out in the splash zone, using a range of recent case histories from both North Sea and International Operator assets. The case histories will illustrate, not only standard cleaning and inspection techniques, but also state of the art inspection using “acfm” sensors for nodal weld crack detection on platform jackets. Much of this work is being transformed by the use robotic techniques to enhance the work of skilled ROV operators. In addition, we will also show how Ocean Tech installed “I” & “J” tubes in a remote offshore location, without the use of vessels, divers or ROV’s resulting in considerable savings for the Operator. No Vessels, No Divers, No ROV’s ……..No Problem!
