Ongoing improvements in 3D printing are helping PMI explore new ways to provide engineered solutions that meet customers’ needs. PMI is improving quality control, prototyping crucial components, and experimenting with designs that will reduce assembly time by taking advantage of 3D printing’s additive manufacturing technology.
“The PMI engineering team has used additive manufacturing to make solid three-dimensional objects from a CAD (computer-aided design) file for several years. Because fabrication materials are improving and becoming more cost-effective, we are investigating more ways we can apply the technology,” says Terrence Mathis, PMI Manager, Engineering-Cable Protection.
Engineering team members are managing small projects to improve mold fabrication, potential part casting, compression dam manufacturing, and more.
Analyzing tolerances and variations to improve quality assurance
PMI is using 3D printing to test engineering tolerances of manufactured parts, such as plugs and rings used in a variety of applications. The time needed to measure internal and external features of parts, and ensure their proper fit, can add hours to the quality control process and affect product yields. Also, it can add time-consuming iterations to production if changes occur late in the design cycle.
“Some complex parts have over 20 features that can take four or more hours to inspect,” Mathis says. “Different tools may be needed to measure each section. Depending on the production quantity, it can add a lot of time. Through tolerance optimization, PMI has the potential to improve manufacturing time and reduce cost.”
Prototyping components that customers need to remain operational
Many of PMI’s field-installable products incorporate helical gripping rods as part of the kit. At times, it is necessary to reterminate a PMI product—sometimes while out on the ocean–to replace helical rods affected by excessive corrosion, or to refurbish the cable connector.
PMI manufactures the DAM/BLOK™ electrical splice kit as a full-ocean depth pressure splice for cable connections. However, there are over 100 existing DAM/BLOK electrical splice kit designs, not including splice kits that can be custom designed for customers. Despite the degree of customization, each kit includes several crucial components, including precision precast compression dams.
Currently, PMI is testing compression dams to ensure it prevents outside seawater as well as leak water within the cable from passing through the splice to the electrical connection. This is especially important at increasing ocean depths.
Developing designs that reduce assembly time
Customers who purchase PMI’s DYNA II cable hangers benefit from its tool-free installation and multiple degrees of freedom, which allow spreader rope loads to pass through with minimal effect on the lead-in and umbilical cables. Like many PMI products, DYNA II can be custom engineered into several configurable kits and accessories.
A collar assembly is just one of the components in a typical DYNA II configuration. PMI is using 3D printing to develop a new standardized collar to be used on legacy and new systems. The prototype collar is 3D printed in a wax resin, which is then cast in stainless steel. The collar serves a build-measure-learn function while saving tooling costs as PMI works to create an improved collar that benefits its customers.
Thinking outside the box to increase development speed
“Our customers turn to us for engineered solutions that include design, fabrication, and testing of subsea tow cables, hardware, assemblies, and protection,” Mathis says. “With a 3D printer, we’re able to take advantage in low-volume situations to revolutionize our development, design and replacement parts in ways that benefit our customers.”

Cleveland, OH— PMI Project Engineer and Marine Energy Specialist Tyler Burger shares his thoughts on the future of cable maintenance and repair in offshore wind farms with Windpower Engineering and Development in the article “The future of cable maintenance and repair in offshore wind farms.”
The third of four Ramform Titan-class vessels, the Ramform Tethys, was celebrated in a naming ceremony at the Mitsubishi Heavy Industries Shipbuilding Co. yard in Nagasaki, Japan today.
PGS’ two first Ramform Titan-class vessels, the Ramform Titan and the Ramform Atlas were delivered in 2013 and 2014 and have delivered beyond expectations on all aspects, especially within safety, efficiency and productivity.
The Ramform Tethys, and the Ramform Hyperion, will be even better due to small modifications of equipment handling on the back deck and an increase in engine power to 26 400 kW from 23 040 kW on the first two Ramform Titan-class vessels.
“With the increased power output and the back deck modifications we are enhancing the Ramform Titan-class acquisition platform further. Productivity, safety, stability and redundancy are the key benefits of these vessels. Their ability to tow many streamers gives high data quality with dense cross-line sampling and cost efficient acquisition with wide tows,” says Per Arild Reksnes, EVP Operations.
The Ramform Tethys is the most powerful and efficient marine seismic acquisition vessel in the world, and along with the Ramform Titan and Ramform Atlas, the widest ships ever at the waterline.
The design dovetails advanced maritime technology to the imaging capabilities of the GeoStreamer® seismic acquisition technology. Her 70 meter broad stern is fully exploited with 24 streamer reels: 16 reels aligned abreast and 8 reels further forward, with capacity for 12 kilometer streamers on each reel. With such capabilities the Ramform Tethys has tremendous flexibility and redundancy for high capacity configurations. Increased work space and advanced equipment handling mean safer and even more robust operations. The Ramform concept design is made by Roar Ramde.
She carries over 6 000 tons of fuel and equipment. She will typically tow a network of several hundred thousand recording sensors over an area greater than 12 square kilometers, equivalent to nearly 1 200 soccer pitches, or 3.5 times Central Park.
For PGS and its clients, more rapid deployment and retrieval of equipment, as well as greater operational capacity will translate into faster completion of surveys and increased uptime in marginal weather. The period between major yard stays is also extended by approximately 50%.
The Ramform Tethys sets the new standard for seismic operations for the next 25 years.
Jon Erik Reinhardsen, President and CEO of PGS states in a comment: “The Ramform Tethys further strengthens our fleet productivity and together with the other Ramform Titan-class vessels will enhance our competitive edge. In the current challenging market environment we also experience more demand for our best capacity and Ramform Tethys will add to PGS ultra-high-end value proposition.”

The launch of the Ramform Titan class marine seismic data acquisition ships by Petroleum Geo-Services (PGS) mark a new era of subsea oil and gas exploration. The second of these vessels, the Ramform Atlas was launched in January, 2014. The Ramform Titan and Ramform Atlas are designed and built by PGS to be the most powerful and productive of their kind using the latest marine and electronic seismic technologies.
Every detail of these vessels was evaluated based on optimum productivity and safety including the cable management systems used to deploy and attach up to a 24-streamer array system. The towed streamers consist of several thousand recording sensors over an area greater than 3,000 acres (12 km2), or 3.5 times the size of New York’s Central Park.
The engineers at PGS have chosen the latest proven technologies available throughout the Ramform Titan-class ships, including the new PMI Dyna-Hanger II and Dyna-BSR cable management systems. These systems provide significantly higher load capacities to accommodate the demands of extreme towing loads caused by wider streamer arrays. As a bonus, the major components of both systems can be installed, or removed, in just minutes without special tools or extensive personnel training to increase on deck productivity and reduce downtime.
The Dyna-Hanger II cable management system uses exclusive patent pending designed symmetrical suspension arms with tool-less features and helical rods. It is designed with a hinged collar that snaps around the housing and is secured with just a quick-release pin. A specially designed housing prevents the attachment point from shifting on the lead-in cable while the collar design enables the cable to rotate freely under tension. It is capable of accommodating loads up to 100% of the cable’s rated breaking strength.
The Dyna-BSR bending strain relief system provides cable bending and abrasion protection, while enabling rotation of various cable attachments. It replaces traditional slip-on bending strain relief systems that use a one-piece body design. Instead, the Dyna-BSR patent pending two-piece system can be installed or removed at any time during deployment or retrieval procedures. It is designed with a reinforced polyurethane, two-part shell to provide added strength and flexibility. A unique fastener system quickly secures the shells together. In total, the system offers graduated stiffness to protect cables from off-axis loads through a wide range of angle combinations by maintaining a safe minimum bend radius.
“Everything on the Ramform Titan class was chosen for its contribution to our primary goals of providing optimal seismic productivity and crew safety,” according to Sverre Olsen, Technical Manager at PGS. “Every sub-system we have, builds on the total system to achieve our goals. PMI systems were chosen because they continue to meet PGS productivity and higher load requirements.”
“The successful PGS installation is a result of our conversations with customers about their challenges then developing cable hardware and support services to meet their needs,” said Bob Schauer, president, PMI industries. “We are focused on unmatched support for our customers. Whether it is easy-to-use hardware, engineering support or comprehensive cable testing services, we listen and then perform.”
