A Track Record you can depend on

With thousands of drill riser buoyancy elements maintained, modified and managed over a 12 year history, we are the premier global repairer

Drill Riser Buoyancy is costly equipment intended to last 20 years. Potential down-time or rejection of riser joints with impaired fitments can result if this equipment is not properly maintained in fit-for-service condition. Buoyancy is unfit for service if it is cracked, broken in multiple pieces, missing major sections, contains deteriorated buoyancy material or has suffered water ingress.

Riser Readiness

We conduct services in field locations where our customers have limited personnel and support. In these situations, we provide a turn-key solution by undressing riser joints, repairing buoyancy and then redressing riser joints to be ready for load-out and return to the rig.

We also carry out buoyancy swop-out, which entails readying the desired number and depth of riser joints, providing reporting regarding damage observed and providing a reliable basis for future budgeting.

Modifications & MPD

Buoyancy frequently requires to improve performance, safety or usability, including for the adoption of MPD or 20K riser capability by the Drilling Contractor.

This can include modification of the main channels order to accommodate a different aux line configuration, installing MUX clamp windows or retrofitting retention strap and tensioner recesses or VIV-suppression improvements.
ProFloat offers seamless engineering and implementation of bespoke modifications through onsite installation and ProFloat proprietary modification techniques.

This work is provided as a stand-alone service or as a part of on-going repairs. The output is a product which is more suited to the Drilling Contractor’s needs.

01

Readiness Reporting

Insight into the depth readiness of a riser string's buoyancy, detailing the elements requiring repair to fulfill contractual depth obligations.

02

Repair Reports

A detailed overview of the work scope conducted per buoyancy element, together with traceability management and COS.

03

Uplift Reports
