Fall pipe ROV –Rockpiper

A revolutionary step in the field of SRI thanks to the introduction of integrated survey ROV technology Rockpiper


Significant operational efficiency gains achieved by direct post-survey capabilities

One significant cost driver in rock-installation operations is the inability of a rock-installation ROV to perform an immediate post-process survey. Rock dust kicked up during rock-dumping prevents the survey equipment from operating properly. As a result, a rock-dumping vessel is required to re-run its track and perform a separate post-process survey. Alternatively, an inspection ROV, including crew, can be deployed. Either way, a very costly matter.

Our client Boskalis approached Seatools with a proposition for the omission of this cost driver: the integration of a survey ROV that follows the main ROV at a specific distance, and performs a direct post-process survey. An exciting engineering trajectory followed, during which Seatools brought the proposed concept to life. The result is a highly automated fall pipe ROV that integrates a survey ROV. The survey ROV features full DP functionalities, and can dock and undock fully automatically.

Project scope
  • Full-fledged fall pipe ROV system, including integrated survey ROV and delivery of training simulator
Project duration
  • 11 months
  • Boskalis

Able to perform a direct post-dump survey, the rock-dumping vessel does not need to re-run its track to perform a post-survey, leading to a reduction in required vessel time and major cost savings. How can we enhance the economics of your operations?

Features & Specifications

  1. Integrated survey ROV for immediate post-surveys

    The main ROV is equipped with a survey ROV that is able to (un)dock itself automatically. In order to perform post-process surveys, the survey ROV positions itself at a fixed relative position behind the main ROV. The result is major cost saver: the survey ROV eliminates the need to perform a separate post-process survey.

  2. Automated precision rock-installation

    Like our fall pipe ROVs, the Rockpiper ROV comes with a large degree of process and navigational automation. This includes functions such as auto-depth, auto-heading, auto-swing, and auto-track. Thanks to the ROV’s high degree of automation, a highly complex subsea task can be performed by a single operator.

  3. ROV simulator for operator training

    Thanks to the ROV simulator supplied by Seatools, operators gain proficiency faster and can experience abnormal system performance in a safe environment.
