Topside inspection and underwater inspections in lieu of drydocking (UWILDs) enable customers to meet class and regulatory requirements without interrupting operations.

Inspection Campaign Management

Inspection and Maintenance Planning

To help drilling contractors and operators comply with class and regulatory mandates, we provide customized, in-depth inspection and maintenance planning. We offer a single-source solution for platforms, FPSOs, and other structures seeking class- or risk-based inspection and maintenance planning.

Working closely with customers, we plan for operations from inspection to maintenance during in-service periods such as active drilling operations, between-well windows, or while producing. We are experienced in complying with the inspection mandates of the American Bureau of Shipping (ABS), Det Norske Veritas Germanischer Lloyd (DNV GL), Bureau Veritas, and Lloyd’s Register.

Topside Inspection Services

Through our Asset Integrity division, we provide risk- and reliability-centered services that enable customers to make informed decisions about critical offshore infrastructure. Our service capabilities range from inspecting a single component at an approved test laboratory to developing and implementing asset integrity management systems.

At any stage of an asset’s life cycle, we use proven workflows and data-driven QA/QC processes to rapidly and cost-effectively provide support. We offer integrated topside inspection services covering maintenance, corrosion, structural integrity, external coating, insulation, and condition monitoring management.

Our services include general and advanced non-destructive testing (NDT), lifting gear certifications, and dropped object prevention scheme (DROPS) planning and inspection.

To best meet riser inspection requirements, our proprietary process enables simultaneous inspection and cleaning while the risers remain in service. By enabling inspection subsea, we reduce the expense, time, and risk associated with transporting risers to shore for inspection and storage. By contracting Oceaneering for riser inspection, customers can keep risers in service on a vessel for up to 10 years without removing float collars.

Spectrum ROV

Subsea Inspection Services

We perform UWILDs to assess the integrity and condition of critical offshore assets—from platforms to FPSOs. With industry-leading technologies and proven processes, we enable customers to remain on-hire while inspections are underway. Planned periodic surveys no longer entail planned work stoppages.

To achieve superior control and effectiveness in all water depths, we either use our existing ROV onboard the drilling rig or deploy our small-footprint, light work class Spectrum ROV. As needed per customer requirements, we are also capable of mobilizing larger ROV systems and vessels for deepwater inspection, maintenance, repair, or drilling support.

On FPSOs or drilling rigs, our smaller ROVs can enter flooded ballast tasks to perform close-up visual inspection, ultrasonic wall thickness measurements, and cathodic protection gauging. Ultrasonic thickness (UT) gauges enable us to measure metal thickness and corrosion without having to remove protective coatings on internal potable water tanks, vessel hulls, ballast tanks, and submerged infrastructure. Cathodic protection gauging is used to determine the level of anode corrosion and expected anode life.

The use of ROV technologies helps us decrease HSE risk, by reducing personnel on board (POB) requirements, and minimize interruptions to customer operations. When necessary to complete specialized tasks, we are also capable of deploying certified divers and International Marine Contractors Association-approved diving packages.

Our custom UWILD tooling enables us to perform maintenance operations at the same time as class- or regulatory-based inspections. Combining scopes enables us to mobilize once for what would otherwise be a two-deployment scope. Our tooling portfolio includes a float cam, which allows for valve inspection without the need to remove functioning valves. We also have the ability to use our dual-isolation plug, which allows for the replacement of valves simultaneous to the ongoing UWILD process, saving time and money for our customers.

For older assets, or those requiring subsea NDT, we deploy a magnetic crawler integrated into the inspection ROV—the crawler performs alternating current field measurement (ACFM), pulsed eddy current, UT, or an NDT method that is specific to the required inspection. This use of the crawler and its ability to attach to an asset with magnetic tracks eliminates the heave and pitch of the ROV and movement of the asset. This capability translates to a more effective, time-saving subsea NDT process.

Global Data Solutions

Our extensive experience on drilling rigs and with remote operations enables us to perform our services with fewer people due to our real-time data transmission capability. We reduce POB requirements, yielding safer, more efficient, and cost-effective operations. Using our shore-based monitoring capability, we can remotely pilot ROVs, position a vessel, and provide a real-time conduit through which an inspector located onshore can view the inspection as it progresses.

Furthermore, where today’s vessel monitoring systems are complex and frequently do not communicate with each other, we offer applications that provide a clean dashboard of an asset’s condition in real time. These data are monitored and only information that indicates a change in condition is sent ashore, limiting the data transmitted and lowering costs charged to the asset.
Lastly, our technical team develops sensor packages that are easily installed and can be added to existing or newly developed condition monitoring systems. These sensors—which track vibration, heat, acoustics, cathodic potential, and more—can be placed in a mudroom, on a pump, in a BOP, or in the derrick. We are capable of designing a bespoke system that is tailored to the customer need.
