Riser clamp
Riser clamps provide secure attachment support for cables, pipelines and umbilicals running vertically along platform structures.
Item link
Riser shim
The riser shim provides support to bare riser joints in critical areas, installed at intervals to assist handling and stacking while matching buoyancy external geometry for consistent riser configuration offshore operations.
Item link
Riser storage wedge
Riser storage wedges enable secure stacking of riser joints in dockside storage environments.
Item link
RiserGuard
RiserGuard provides complete protection for bare riser joints and external lines during handling, storage and drilling operations, reducing impact damage during running, retrieval and storage in offshore drilling environments.
Item link
Stackable RiserGuard
The stackable RiserGuard provides complete protection for bare riser joints and external lines during handling, storage and drilling operations.
Item link
Stop collar

Benefits

Stable storage and riser containment system

Grommets provide centralised support and containment for riser joints during dockside storage. Using u-shaped polyurethane cradles and stacking wedges, they enable safe modular stacking of drill riser buoyancy modules without increasing external profile or compromising stability.

Centralised support
Provides centralising of riser joints and associated lines, ensuring stable positioning within storage racks and reducing movement during dockside handling and stacking operations.
Stable stacking
Riser bay stacking wedges and cradles enable secure stacking of drill riser buoyancy modules, improving storage efficiency and structural stability within modular racking systems.
Low profile
Does not increase external profile of riser assembly, allowing efficient storage while supporting compatibility with existing dockside handling and storage infrastructure systems.
