Topsides & Hulls

Weight & Space Optimization

Offshore Piping Connectors

Reducing offshore structural loads by up to one million pounds per platform.

1. Offshore Topsides

Offshore platforms and FPSOs leave no room for connection failures. Taper-Lok connectors are used where weight limits, tight spaces, and zero leak tolerance all apply at once. Replaces bulky ANSI/API flanges.

2. Weight & Space Savings

Taper-Lok cuts flange weight by up to 80% against ANSI flanges. Pipe runs sit closer together, opening space for equipment and future tie-backs. Less structural support is needed.

3. Seal Technology

Wide-area metal-to-metal seal covers up to 20 times the contact surface of competing designs. The seal is self-energizing—pressure pushes it tighter, not looser.

4. NORSOK L-005

CofferLok meets the stringent NORSOK L-005 standards for compact flanged connections in offshore service, providing the documentation and confidence required for North Sea and international projects.

5. Valve & Vessel Work

Works equally well on valves, pressure vessels, nozzles, and skid equipment. Standardizing on one compact flange type simplifies inventory and reduces training requirements.

6. Real-World Tolerance

Taper-Lok's wide-area seal has enough contact depth and surface to bridge minor imperfections and still hold a reliable seal, avoiding unnecessary delays due to minor handling damage.

The Advantage

Why Choose Taper-Lok Topsides?

Flange leaks on offshore platforms cost more than just downtime. Taper-Lok and CofferLok get rid of the gasket entirely, replacing it with a self-energizing metal-to-metal seal that holds firm through pressure spikes and vibration.

The connectors are up to 80% lighter than ANSI flanges, handle pipe misalignment without rework, and work across topsides, hull piping, and FPSOs without needing different solutions.

Common Questions

Offshore FAQ

Where can these be used offshore?

Across topsides, hull piping, FPSOs, jacket structures, and subsea spools. They connect pipe to pipe, pipe to valve, and pipe to vessel—covering most connection points on a platform.

How do they ensure leak-free performance?

The metal-to-metal seal is self-energizing. When pressure builds, the seal contact increases rather than relaxing. Thermal swings and vibration do not change this behavior.

Can they replace ANSI/API flanges?

Yes, on both new build and retrofit projects. Pressure and load ratings match or exceed standard flanges. The physical footprint is smaller and the weight savings are immediate.

How do they improve safety?

Removing gaskets removes the most common leak point. Fewer leaks mean fewer hydrocarbon release incidents, fewer unplanned shutdowns, and a safer environment for personnel.
