Locks down leaks fast and easy
Norclamp Padlock is a lightweight, patch‑style subsea repair clamp designed for rapid sealing of localized pipeline damage.
The clamp is installed without the need for heavy lifting equipment, using a simple cylinder mechanism to close around the pipe, followed by torquing a single bolt to activate the seal.
Once engaged, the integrated patch is driven directly onto the defect area, creating an effective localized seal rather than a full 360° enclosure.
Its low weight, simplified installation, and ability to accommodate multiple pipeline sizes make Norclamp Padlock a highly efficient solution for quick interventions, particularly in situations where crane use is impractical or access is limited.
Recommended applications
Urgently required repair solution for smaller active leaks.
- Pin holes
- Pitting
- Small girth weld defects
- Defect area — very short
- Sealed
Key benefits
- Fast installation within hours using only a torque tool – no crane or lifting equipment required
- Cost-efficient with short lead times due to simplified manufacturing
- Ideal for EPRS applications, enabling rapid response when time is critical
- Compact and lightweight design for easy storage and immediate availability onboard vessels
- Unified design for diver and ROV installation, reducing operational complexity
- Interchangeable inserts allow one clamp body to fit multiple pipeline sizes, minimizing inventory and cost
- Simple, robust, and versatile design suitable for a wide range of applications
- Rental options available, eliminating upfront CAPEX for contingency equipment
- Pre-deployed rental solution on IRM vessels, enabling immediate installation upon leak detection
- Enhanced operational readiness with instant leak response capability—reducing downtime, environmental impact, and regulatory risk
