SUBSEA TECHNOLOGY I
n the realm of marine and off shore operations, the
deployment of remotely operated underwater vehicles (ROV) is pivotal. A critical aspect of their functionality hinges on the eff iciency and safety of the equipment used, particularly the hooks for lifting and manoeuvring tasks. RUD, a major manufacturer in this sector, has worked with one of the world’s leading subsea construction and remote intervention companies to develop an ROV Hook that stands out for its innovative design and operational eff iciency.
BACKGROUND AND
DEVELOPMENT The inception of the RUD ROV Hook was in response to a customer request, aiming to tackle specifi c problems associated with
conventional ROV hooks. Traditional hooks were prone to two major safety issues: unintentional opening or ‘shedding’ and accidental snagging due to protruding parts. These issues were not only operational hindrances but also posed signifi cant safety risks in deep-sea operations.
DESIGN INNOVATIONS RUD’s approach involved rethinking the conventional hook design. The key innovation in the company’s ROV Hook lies in its outward- opening latch, a strategic design choice to combat the shedding issue. Additionally, the hook’s overall design was streamlined to reduce snagging risks. The product’s ease of operation was a central focus, with the aim of enhancing safety and operational eff iciency.
OPERATIONAL EFFICIENCY A notable feature of the hook is its one-handed operation capability. This design allows for quick and secure attachment and release, a crucial factor in operations where time and precision are of the essence. The integration of a reliable locking system, activated by a trigger mechanism, ensures that the hook remains securely closed

EXTENDED VERSIONS AND ADAPTABILITY Following the initial version and based on qualifi ed user feedback, RUD introduced an extended version of the hook featuring a twin-trigger mechanism. This addition provides a two-stage securing process, further enhancing the safety and versatility of the hook. The availability of diff erent load capacities, including the original 10t and an expanded 25t version, allows for a broader range of applications in underwater lifting and manoeuvring tasks. The ROV Hook represents a
considerable advance in the fi eld of ROV operations. Its design and
functionality address the critical safety and eff iciency challenges previously encountered with traditional hooks. The product’s ease of use, coupled with its robust locking mechanism, makes it a valuable tool in the arsenal of deep-sea operations, off ering enhanced safety and operational eff iciency. As the industry continues to evolve, tools such as the ROV Hook play a crucial role in enabling safer and more eff icient underwater operations. For further technical details and
specifi cations, interested parties should consult RUD’s off icial documentation or contact their technical support team.
