Bas Coppes Appointed Director of Salvage & Wreck Removal

February 6, 2017

Bas Coppes has joined the senior management team at Global Diving & Salvage, Inc., aiming to guide the global growth of the marine services company. Coppes will be based out of Global’s Houston, Texas office and will be focusing on salvage and wreck removal operations worldwide.

Coppes brings two decades of salvage and offshore experience to the organization, having managed an extensive number of salvage, wreck removal, and offshore projects across the globe.

“In my role as president of Mammoet Salvage Americas, I worked with Global extensively over the last ten years,” Coppes said. “Global was, without a doubt, the key to success on the high profile salvage of the SSV Jupiter 1, Robson Bight, and USAT Brigadier General M. G. Zalinski. For me, this is the next step in uniting our extensive experience under one roof. I look forward to pushing the limits on smart solutions in the salvage industry on a global scale.”

“I am very pleased to welcome Bas to Global,” said David DeVilbiss, Vice President of Casualty Response at Global. “He is well known in the industry and a natural fit for our can-do culture.”

A Closer Look at Global's Logo

January 23, 2017

If you look closely at the gold diving helmet in the center of the Global Diving & Salvage logo you might notice that there’s something missing. It’s a subtle, slight mistake that – 35 years ago – fit the vision original owners Thom Davis and John Graham had for the company.

The helmet in the logo is missing a wingnut and a stud. The company’s current President and CEO Devon Grennan has never gotten a straight answer on if that mistake was purposeful or not, but joked that maybe, “it just made sense not to have it because the guys themselves were a little bit of a loose nut themselves.”

At the time, the founders were mostly single guys leaving well-paying jobs to start a dive company without much startup capital. But, what they lacked in funding, they made up for with a long-term vision.

“I think that kind of entrepreneurship and that kind of belief in yourself sometimes looks like you’re crazy to the outside world and other times like you're on the right track,” Grennan said. “I think they thought that the missing wingnut was a good reminder of that.”

So, while Grennan doesn’t know the exact origin of the wingnut omission, it fits the company’s humble beginnings – a tribute to a tradition that endures to this day.

Other aspects of the logo provide a peek into the history of the company and the industry. For instance, the helmet; Global was started at a time when people were transitioning from the heavier helmet pictured (a Mark V) in the logo to a lighter, fiberglass one.

So, why did Davis and Graham want to showcase an older helmet? In addition to paying homage to the history of diving, “they wanted something that was bold and recognizable,” Grennan said.

Just under the helmet in the logo, there is a thick black line, tracing above the blue waves below. That line symbolizes oil.

“Back in those days there were a lot more oil spills to respond to,” Grennan said. “Responding to an actual marine oil spill was a pretty common event back in the late ’70s, early ’80s. They wanted to nod to the fact that they did oil spill clean up as well, which is why they have the black wave line above the blue water.”

Completing the logo are latitude and longitude lines, forming the frame of a globe that circles the rest of the image. While the company had humble beginnings, adding “global” to both the name and imagery was a testament to the bold vision of what the founders’ believed the company could create.

“We are very fortunate that they didn't call themselves Seattle Diving, Harbor Island Diving, or Puget Sound Diving because we would have had to change the name a long time ago,” Grennan said.

Looking back on that original image, only one thing has changed throughout the company’s 35 years. Where it used to read: Global Diving & Salvage, Inc., only one word remains – Global. The company has grown over the years, but Global remains true to its roots.

“That fact that the logo is in a globe shows we are not confined by specific region or area and we will go where the work is, but it reminds us and our clients we have that go-anywhere attitude to take care of business,” Grennan said. “We still want to tie back into who we are, where we came from and where our roots are in both commercial diving and the fact that the water is there and the oil on top of it recognizes or gives precedence to the marine services that we do in addition to commercial diving.”

Everything about Global’s logo is intentional, from what was included to what was left out, and it continues to be a point of pride for past and current employees. “It really set the vision for the company 35 years ago, one we have been able to realize,” Grennan said. “Our employees take pride in working for a company with strong roots. We are a company that can and does respond globally.”

Salvage & Wreck Removal: Answering the Call Anytime, Anywhere

December 23, 2016

Global’s service offerings have expanded significantly since our initial focus on diving operations in 1979, but one of our founding capabilities - salvage and wreck operations - continues to be a success through the completion of hundreds of projects around the world. While every call is unique, our team brings quick response, thorough planning, and determination to each project.

With decades of experience in dealing with complex operations involving numerous challenges, our staff is extremely skilled and knowledgeable. While every project is unique with its own set of challenges, Global is ready to respond 24/7 whatever the problem. “The process starts immediately,” says David DeVilbiss, VP of Marine Casualty Response. “We find out the facts and start doing research on location, tides, and what resources we have near the area.”

Salvage and wreck operations involve intricate planning and adherence to strict environmental and insurance requirements. We work with local suppliers across the world stocked with a wide range of containment and recovery equipment.

As soon as our team is notified of an emergency, a salvage/recovery expert is dispatched to the site. “90% of the time we can have someone anywhere in the world within 24 hours,” states DeVilbiss. “If the client is on site, we always meet with them first, or local Coast Guard, naval, or maritime authority when necessary.”

In addition to mobilization resources, Global maintains flyaway assessment kits called ‘go kits’ at strategic locations. With equipment including gas analyzers, hand-held depth tanks, radios, and recording devices at the ready, seasoned pros can hit the ground (or water) running with everything needed to gather vital site information.

Aside from salvage and wreck, our specialists also handle all aspects of marine casualty operations, including those above the surface. Even with hundreds to thousands of projects completed over the years, no two projects are the same. Our team is adept at navigating the complex organizational requirements, as well; securing local permits, insurance needs, and efficiently managing environmental and political concerns. Our on-site personnel expedite administrative tasks, helping to minimize loss and expenses for clients who may already be facing financial hardships. DeVilbiss explains, “At the end of the day, I like to think that we have made somebody's life better.”

For immediate, expert advice and response to sunken vessels and other marine casualties, call our 24-hour, international toll-free line at 1-800-441-3483 to speak with a local expert in your region.

Preserving Puget Sound’s Maritime Past and Future

November 22, 2016

At Global we’re proud of our historical ties to the Puget Sound’s maritime industry and are devoted to protecting the history of the region. We have been a supporter of Puget Sound Maritime (PSM) for more than a decade. PSM’s mission is to create appreciation of the Puget Sound region’s maritime past in order to better understand the present. Global co-founder, Tim Beaver, was the driving force behind Global’s association with the organization.

After many years of involvement, Beaver decided to step aside and asked if Frank Immel, Global's Business Development Account Executive would get involved. “I have a passion for the maritime industry and the historical involvement it has played in the region,” says Immel. The organization undertook an effort to become more current and relevant, ‘today becomes tomorrow’s history.’ Immel assumed the role of President in 2014.

Founded in 1948 as a non-profit, PSM is now housed in the Museum of History & Industry (MOHAI) in Seattle. Artifacts from Global, as well as Beaver’s own personal collection are on display at the MOHAI. The organization maintains and promotes interest in the region’s deep maritime history. Puget Sound’s maritime sector is a major driver of commerce throughout the Pacific Northwest. Seattle is one of the west coast’s main ports, facilitating trade and travel for the world. It’s also home port to trawlers fishing the Alaskan seas. The society preserves the region’s maritime past with an archive featuring more than 60,000 photos, thousands of ships plans (including the entire Ed Monk Jr. collection), numerous ship models, artifacts, logs, and documents.

Under Immel’s leadership, one of the society’s chief initiatives is educating the region’s youth about maritime career opportunities. Approximately 40-50% of tug and ship captains will soon retire. As the pipeline of experienced hands narrows, the need for tradesmen at all levels will become increasingly vital. PSM has partnered with Youth Maritime Training Association with the aim of educating students, as well as adults looking for a new career, about all the industry has to offer as an exciting, fulfilling option in lieu of or after college.

Global proudly supports PSM and its efforts to preserve the region’s maritime past to better understand its present, as well as attract the youth needed to drive its future. For more information, visit the society’s website at

Renee Gowdy Receives Global's Yoke Award

October 25, 2016

Once a year, we take a moment to recognize a single Global employee who best represents the “Global spirit” by their willingness to shoulder the load. We are pleased to announce the 2015 winner is Renee Gowdy, our Estimating Group Manager in the Marine Construction division.

On her nomination, it noted that Renee has always been willing to step in and assist wherever and whenever necessary. She takes great pride in Global, which is reflected in everything she does. Her attention to detail and standard of excellence sets the bar for those working with her. Renee’s attitude and approach to her job is an excellent example of what we mean by the “Global spirit.”

The origin of the Yoke award stems from Global’s earlier years when we all did more with less (just like today). We wanted to find a way to recognize our employees for their hard work, going above and beyond, and pitching in to help get a job done. So we bought a goat yoke on eBay for $60, sanded the paint off it, and secured it to a board. Funny how traditions start.

Global Achieves 10,000 Dives on a Single Project

October 17, 2016

Global Diving & Salvage, Inc. has surpassed a major industry milestone; performing 10,000 successful dives on a single project at Olmsted Locks & Dam in Illinois. Tom Cameron, a long-time diver with Global, performed the 10,000th dive.

Wade Miller, Marine Construction Manager with AECOM for the Olmsted Dam Project, said, “The Global team has done an exceptional job. This accomplishment is such a strong statement regarding their professionalism and commitment to performing their work safely.”

Global has been working at Olmsted since 2009 providing a variety of dive-related services. Olmsted is a significant, ongoing undertaking. The new locks and dam system will replace two outdated locks and dam systems on the Ohio River, greatly reducing tow and barge delays through one of the busiest US inland waterways. Thousands of man hours put in by the United States Army Corps of Engineers (USACE), AECOM, and Global constitute essential work toward the completion of this enterprise; one that will span a quarter of a century and provide efficient passage up and down the Ohio River.

“This is a monumental achievement for everyone involved,” said John Graham, Director at Global. “This milestone demonstrates our diligence and commitment to safety in carrying out all of our operations; from a simple tug survey to a long-term project such as this.”

Global Receives Tesoro's 2016 Shared Value Award

October 3, 2016

Global Diving & Salvage, Inc. has received Tesoro’s 2016 Shared Value award. This award recognizes Tesoro’s service providers for significant improvements in working with and creating value for Tesoro and its key stakeholders.

Global was one of 13 service providers recognized by Tesoro amongst their wide-ranging supplier network. Specifically, Global was recognized for their preventative booming operations at the Anacortes, Washington refinery over the last nine years. Gary Mattson, Tesoro Superintendent, stated, “Global has provided safe, reliable service since the implementation of the pre-booming requirements. However, their true value is found in the ways in which they evaluate the issues Tesoro struggles with and the ways they contribute. Global has consistently acted in the best interests of Tesoro.”

Devon Grennan, CEO of Global, remarked, “On behalf of Global, I extend my appreciation to our Anacortes personnel along with their Tesoro peers who have made the marine operations at the dock safe, efficient, and environmentally sound. It is a testament to our employees’ values that they look out for the best interests of our clients while performing their work.”

Honesty & Integrity Hold Deeper Meaning

September 22, 2016

Back when Global was first founded in 1979, there were no video systems to provide clients with an opportunity to see things through the eyes of the diver beneath the surface of the water. In those early days of the company, each client had to trust that Global was working in their best interest. If Global co-founder, John Graham, was called to inspect the running gear of a tugboat, he had an obligation to the client to provide a truthful assessment.

“The diver would have to come back with his mental notes, describe the situation to the client and then be asked whether the client should dry dock the boat,” said Devon Grennan, Global’s CEO and President.

That relationship between Global and its clients provided the foundation upon which the company built its reputation. Grennan has explained that there is a deeper meaning within Global’s core values of honesty and integrity. Those two words are at the heart of every employee and at the heart of every project. Honesty and integrity are ingrained in the culture.

The quality of being honest is defined as, “honorable in principles, intentions, and actions; upright and fair.” Therefore, in order to have a truly honest culture, not only do Global employees have to hold honesty as a core principle in their own lives, but they need to act with moral intentions at all times on the job. It is a high standard to hold of your work force, but an important standard at the core of Global’s success. It's helped us earn and maintain the trust of clients.

“Global divers had to give honest perspective and provide solutions with integrity, because those opinions usually came at an expensive price to our clients,” Grennan said. “We carry this same approach toward our work with us today.”

Global has grown to become an international marine services provider and the largest provider of marine construction and support services in the United States because of the longstanding history of honesty.

“[We need to] be mindful that we hold ourselves to a higher standard than simply getting the work done: we execute our work in a manner that we can stand behind,” Grennan said.

Honesty, integrity and trust are not values unique to Global, but based on the way the company was built, the deeper meaning found in those ideas will always be a pivotal part of everything we do.

Global Technical Services

August 25, 2016

As our operations have expanded to take on larger, more-complex projects, the need for internal training has also grown; as well as our need for skilled Quality Assurance (QA) and inspection personnel. Global Technical Services (GTS) was created to provide our customers with turnkey solutions for these industry needs.

“We do things at a very competitive rate without sacrificing quality,” says Billy Christensen, Operations Manager. “In our industry, integrity is huge. We pride ourselves on quality, consistency, safety, and efficiency.”

Three Decades of Underwater Excellence

July 20, 2016

Founded in 1979, Global started as a group of six dedicated, independent divers, all with the goal to make a living doing what they loved. Today, the company is the largest provider of marine construction and support services on the West Coast. We’ve come a long way by delivering on the toughest jobs and remaining true to our passion for diving, performance, and safety.

Prior to Global’s founding, the diving and salvage industry was primarily composed of freelance two-man teams - a diver and tender. As shipyards grew in the Pacific Northwest, the need for formalized marine-services companies grew as well. The passing of the National Environmental Policy Act of 1969, which mandated that companies clean up maritime oil spills, also meant business was booming.

To meet this new demand, several outfits formed, including Seattle-based Crowley Environmental Services (CES). It was here that Global’s founders -- John Graham, Greg Harem, Thom Davis, Mark Niccoli, Norm McCullum, and Joe Antounucci – first met. “Crowley has to be credited with teaching us much of what we learned,” says Thom Davis. “It was a great company to work for.”

The founders discussed starting their own diving company for nearly a year. Within CES, they were already essentially running their own business, and calling their own shots. Once decided, they moved forward quickly. Greg Harem was elected company president over drinks at a lounge at Seattle-Tacoma International Airport, minutes after returning from a dive job. So they dubbed their newfound company Global Diving & Salvage.

After a trying first year, Global established itself as a reliable crew of skilled, determined professionals. One invaluable customer was Dave Anderson, dockmaster at Todd Pacific Shipyard, who met the Global team while they were with CES. Impressed by their ability to safely complete any job, whatever the hour or conditions, he made them his single call for his diving needs. “These guys learned so quickly,” Anderson says. “They knew what I wanted before I even knew what I wanted.”

As our reputation has grown, so have our equipment resources, service offerings, and customer base. Today we have four regional offices across the U.S. Our crews work around the world, completing major construction projects, cleaning up oil spills, and salvaging vessels. All projects are preformed with the highest dedication to crew safety and performance excellence. We also provide ship husbandry, training, non-destructive testing, QA inspections, and marine consulting services to public and private organizations across the globe.
