Data and safety

By ensuring damaged fitments are attended to promptly and compliantly, riser joint relegation due to damaged fitments and other safety concerns can be alleviated.

Bouyancy Repairs

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.

ProFloat has developed a best-in-class repair method over 10 years of service, seeing us keep thousands of pieces of equipment in service.

We have technicians trained in all categories of repair across all OEMs of drill riser buoyancy.

Combining this expertise with specialized products and materials intended for rigorous offshore use, we provide a repair quality, speed & flexibility which is difficult to match.

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.

Parts & Spares

ProFloat are an OEM and suppliers of various auxiliary equipment required for dressing riser & specialized joints.

Riser Guards (Riser joints, Telescoping joints) (OEM)

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.

UPLIFT™

ProFloat provides critical information relating to the repairs or modifications undertaken. These aspects are critical to compliance with future regulation:

Readiness reporting:

This specialized reporting process gives Drilling Contractors insights into the depth readiness of their riser string’s buoyancy, by detailing the number of elements requiring repair to fulfil contractual depth obligations.

Repair Reports:

Following repair, we provide detailed overview of the work scope conducted per buoyancy element, together with traceability management and COS.

Uplift Reports:

We provide detailed uplift reporting indicating weight, volume and expected uplift per buoyancy element following repair. This serves in calculating riser string hook loads – an important consideration during ambitious well depths.
