Chopsaw [Data Sheet]
Oceaneering chop saws were designed for seamless ROV cutting operations and have applications in severing pipelines, in removal of scrap or salvage, or other offshore tasks where a cost effective and efficient cutting tool is required.

Suitable for use with ROVs of opportunity, the chop saws are available in various sizes, can be functioned in a manipulator for small diameter cuts or supported by integral flotation for large diameter pipeline or jacket member removals.

Pipe Grapple [Data Sheet]
The Pipe Grapple Tool is designed to accommodate pipes up to 18 inches in diameter. The tool is deployed by downwire and is driven by hydraulic cylinders. The grapple can be equipped with an intuitive software package which gives the topside user real time data on the jaw position. Custom sizes can be built to client specifications.

FBE/Weldseam Removal Tool [Data Sheet]
Oceaneering’s FBE & Weldseam Removal Tools remove the factory weld seam and pipe coating during repair operations. Through experience and testing, Oceaneering has been able to adapt this tool to function on a variety of coatings including FBE and PTFE (plastic) up to 3/16in thick. This tool is designed to integrate with any ROV of opportunity which can provide serial communications and 24V supply to the onboard 5 station hydraulic valve pack. Operation of the tool is run by DTS personnel on surface via laptop/software controls. Standard designs are available for 10in to 24in.

Mechanical Pipe Lift Frames [Data Sheet]
Oceaneering’s Mechanical Pipe Lift Frames (PLF) are capable of lifting up to 24in pipeline 84in off the sea floor to facilitate repair and inspection operations. The mudmats fold (as shown) to reduce deck space requirement on the vessel and increase stability in the water column during deployment. Standard mudmats are designed for 25 psf or higher soil strengths at rated PLF loading. Custom mudmats, clamp configurations, and load ratings are available upon request.

Pig Launcher and Receiver [Data Sheet]
The Pig Launcher and Receiver (PLR) was designed to meet customer requirements for field commissioning operations. The PLR is easily modified to function as a pig launcher if required. The PLR may be configured through any range of operating pressures. All valve operations are Remotely Operated Vehicle (ROV) operable based upon DTS’s extensive experience with ROV tooling.

Pre-Measurement Tool [Data Sheet]
The Pre-Measurement Tool (PMT) is a hydraulically operated, taut wire measurement system capable of replicating the subsea condition between an export or flowline jumper hub and a manifold or tree hub. Through a series of hydraulic functions via a Remotely Operated Vehicle (ROV), operators can take repeatable measurements of the distance, elevation, and azimuth between subsea hubs. Jumper fabrication follows with the measurements from the PMT and takes place on the vessel deck or at the fabrication yard.

Simple to operate and easy to maintain, the PMT is a cost-effective alternative to high- cost acoustic measurement systems. PMT packages have been utilized successfully on subsea developments in the Gulf of Mexico throughout the 1990’s and are now also in use for numerous West African Developments.

Flowline Plug [Data Sheet]
Oceaneering’s Flowline Plugs include a packer-type seal and carbon steel slips for mechanical holding. The Flowline Plug also incorporates a mechanical locking mechanism which consists of large Belleville springs and a threaded inner body to ensure mechanical force remains on the seal and slips after Remotely Operated Vehicle (ROV) hydraulics are removed. This allows for the plug to be left in the pipeline during other ROV operations.

Go-No-Go Gauges [Data Sheet]
Oceaneering’s Go-No-Go gauges are used to ensure API maximum ovality tolerance is not exceeded prior to installation of a connector. This operation is critical to the proper sealing of many grip and seal type connectors. By using this tool, considerable time can be saved in the event the pipeline has been damaged in a way which will impede slips and/or packers from seating properly.

Midspan Straightness Gauge [Data Sheet]
Oceaneering’s Midspan Straightness Gauges are used to ensure API maximum bend tolerance is not exceeded prior to cutting a pipeline for repair. This operation is critical to the proper alignment and sealing of many grip and seal type connectors. By using this tool, potential repair sites can be evaluated before losing valuable days stripping coating and preparing ends for grip and seal connectors.

Pipe End Prep Tool [Data Sheet]
Oceaneering’s Pipe End Prep Tools are designed to remove burrs from the ID and OD edges of a cut pipeline. The prepared pipe end is less likely to damage packer seals during grip and seal repair clamp installation, or pigs in future cleaning operations. The
low hydraulic flow requirement makes these tools ideal for any Remotely Operated Vehicle (ROV) of opportunity. Various sizes of the pipe end prep tool have already been designed and built for pipe ranging from 10”- 24”. Customized versions are also available.

Subsea ROV Winch [Data Sheet]
The Subsea ROV Winch has a lightweight and compact design for easy handling. The winch has 28,660 lbs. pull and it can be operated without any need of wires from the surface. The Subsea ROV Winch is an independent tool without any mechanical or hydraulic connections to the ROV.

The winch is parked in a standard API 17D Class 4 interface.
