Efficient Subsea Operations with CAN-Parking Technology in the Norwegian Sea

Efficient field development is crucial in the offshore oil and gas industry, where rig costs often represent a significant portion of total expenses. Innovative solutions that reduce rig days, streamline operations, and enhance safety are in high demand. Neodrill's CAN-parking technology is proving to be one such solution, demonstrating significant cost savings and operational efficiency in subsea environments.

What Is CAN-Parking Technology?

CAN-parking is a robust subsea well foundation solution developed by Neodrill.

Initially designed to improve well foundation installation, the CAN technology

has evolved to serve additional applications. CAN-parking provides a secure and

efficient platform for handling heavy subsea equipment, such as Christmas trees

(XTs) and Blowout Preventers (BOPs), streamlining their storage and

deployment processes.

Recent Installation in the Norwegian Sea

On November 27, two CAN-parking units were installed on a greenfield site on

the Norwegian Continental Shelf (NCS). These units, positioned near a subsea

manifold template, will facilitate the wet parking of XTs. By pre-parking the XTs

in good weather conditions, the installation phase becomes less dependent on

rig availability, reducing delays caused by adverse weather and minimizing

operational risks.

The benefits of wet parking XTs on CAN-parking units include:

• Eliminating BOP re-runs: Avoiding the need to retrieve and re-run the

BOP between XT installations saves significant rig time.

• Reducing onboard equipment: Keeping XTs off the rig reduces equipment

and space requirements, lowering offshore service crew numbers and

associated safety risks.

• Enhancing operational safety: Minimizing crew and equipment

interactions offshore decreases environmental, health, and safety (EHS)

risks.

Proven Benefits from Previous Projects

The CAN-parking technology has previously been used on brownfield sites with

impressive results. In one instance, a Horizontal XT (HXT) was removed from a

well slot and temporarily stored on a CAN-parking unit. The BOP, serving as a

running tool, facilitated the operation. This approach allowed the BOP to return

to the well slot for a sidetrack operation while the parked HXT underwent a

health check using a subsea Workover Control System. Once the sidetrack was

completed, the HXT was reinstalled, bypassing the need for onshore retrieval

and maintenance.

Key benefits observed in this project included:

• Significant rig time savings.

• Reduced equipment handling and maintenance requirements.

• Enhanced safety from fewer rig-based operations.

A Sustainable Future for Subsea Operations

After completing their use on the current greenfield site, the CAN-parking units

will be relocated and reused at other fields, bypassing the need for onshore

transport. This operational flexibility underscores the sustainable nature of

CAN-parking technology, offering both environmental and economic advantages.

Looking Ahead

Neodrill’s CAN-parking technology continues to provide value for offshore

operators, enabling safer, faster, and more cost-effective subsea field

developments. As more operators adopt this solution, Neodrill anticipates

further innovation and applications for the technology.
