ROV HAKUYO 2000 (Remotely Operated Vehicle) |
HAKUYO 2000 is the result of extensive field experience with more 5,000 hours of operation.
Its progressive program spanning more than 10 years and encompassing 2 previous remotely operated vehicles owned by SNK OCEAN CO., LTD.
Each successive vehicle incorporated new ideas and technological advances
where these advances would improve either performance, reliability or maintainability
without compromising any of these three fundamental requirements.
This in turn means improved operational capability and less downtime for
the customers.
