Kawasaki completes verification tests for close-range AUV inspections

Kawasaki Heavy Industries has completed verification tests for the close-range inspections of a subsea pipeline by an autonomous underwater vehicle (AUV) off the coast of Awaji Island, Hyogo Prefecture.

With a focus on the growing demand for pipeline maintenance in offshore oil and gas fields, Kawasaki has been developing an AUV called SPICE (Subsea Precise Inspector with Close Eyes) equipped with a robot arm for performing subsea pipeline inspections.

During verification testing, SPICE executed a close-range inspection process which involved deployment at sea to locate and perform tracking operations on a subsea pipeline, after which it returned to its docking station for recovery.

These tests were part of a series of tests required to verify autonomous operation capabilities, and conducted with the support of the Joint Technological Development Support Program for Offshore Oil and Natural Gas Fields, which is supported by DeepStar and The Nippon Foundation.

SPICE’s verification tests entailed inspections of a mock pipeline used to simulate a real subsea pipeline, located off the shore of Awaji Island in Hyogo Prefecture.

The tests succeeded in verifying the performance of SPICE’s autonomous robot arm control and sensor-equipped close-range inspection unit to track the pipeline while the AUV maintained stable travel, and represent a major step forward along the company’s path to commercialization.

Kawasaki will continue to carry out verification tests using equipment fitted with various inspection sensors in reflection of actual market needs, while simultaneously pursuing classification-society certification for its AUV.
