Fleet
Quite simply, PGS has the most flexible fleet of high-capacity streamer vessels in the world. Crewed by highly experienced personnel, there is virtually no limit to the survey style and parameterization pursued by our vessels.
From specialized technologies aimed at specific marine environments, such as obstructed or hazardous environments, to super-efficient regional surveys, PGS leads the seismic industry. Since about 2001, PGS has pioneered and grown the High-Density 3D (HD3D) seismic market for streamer operations, exploiting the combination of optimal data sampling and optimal survey efficiency.
Backed by innovative pre-survey planning capabilities, comprehensive acquisition and processing QC technologies, and a global network of processing centers, PGS prides itself on its performance and HSE record.
At the same time, we are aggressivly seeking to continually improve those performance and HSE records, using focussed R&D efforts, transparent operating methods, and the dedication of our personnel.
Ramform Vessels
Ramform Sovereign (launched in 2008)
The new vessel is 16 meters longer than the previous Ramforms with significantly higher acquisition and transit speed, 25 percent longer endurance, and 60 percent higher production capacity compared to the existing Ramform fleet. The Sovereign is easily the most powerful seismic ship in the world and features many new innovations, including the world’s first roll compensated helideck, steerable sources, dual workboat capacity and unique gear handling systems. The range of technologies employed promises to make this the new benchmark for 3D, 4D and wide azimuth acquisition – in terms of productivity, efficiency, safety and data quality. Read more
Ramform Vanguard (launched in 1999)
Launched in the spring of 1999, the Ramform Vanguard was the last of the six-vessel Ramform program. Read more
Ramform Victory/Shigen (launched in 1999)
Another of the "V" class ships, the Ramform Victory holds the industry record for the largest spread ever deployed, towing 16 streamers on a HD3D survey in the North Sea in 2001. The total spread comprised 72 kilometers of active in-sea streamer. Despite the enormous size of the spread, the stability of the Ramform is such that the vessel did not need to retrieve the in-sea gear from start to end of this four month project. The vessel was sold to the Japanese government in January 2008 and renamed to “SHIGEN”. PGS continues to be involved in the daily operation of the vessel. Read more
Ramform Viking (launched in 1998)
Built alongside the Ramfom Valiant, and launched three months later, the Ramform Viking has delivered equal performance standards in all environments. Read more
Ramform Valiant (launched in 1998)
This was the first of the 20 streamer "V-class" ships in the Ramform series. The Ramform Valiant holds the current world record for daily production with 111 square kilometers during 1998. Read more
Ramform Challenger (launched in 1996)
The second Ramform class vessel, the Ramform Challenger was the first vessel ever to acquire 2,000 square kilometers in 38 days, then first to do the same in a single month. Today, she regularly reports sustained average production of at least 50 square kilometers per day. Read more
Ramform Explorer (launched in 1995)
This boat launched the Ramform class and was the first ever seismic vessel to tow eight streamers, the first to acquire over 1,000 square kilometers in a month, the first to tow 12 streamers and the first to acquire 100 square kilometers in a single day. In 1998 the vessel towed industry's widest ever single-vessel spread: 1,350 meters. Read more

CONVENTIONAL Vessels
Many of the technical and design breakthroughs which characterize the Ramform class were prototyped on our classic 6 streamer vessels. These modern, high capacity seismic ships are a perfect complement to their Ramform counterparts.
Nordic Explorer
The Nordic Explorer was the first vessel to tow a five streamer spread in 1993, and was the vessel which pioneered multiple banks of streamer reels. She was the first ever high-tech vessel to work in West Africa, offering full onboard seismic data processing and a spread of more than four streamers for the first time in the area. It was the Nordic Explorer which first tied up next to the Norwegian research vessel Marjata in Bergen harbour, and noted the potential significance of the Ramform hull design for high capacity streamer operations. That moment of inspiration led to the six Ramform seismic vessels exclusively operated by PGS today. The Nordic Explorer has operated in the Asia-Pacific area since late 1996, and has been upgraded to six-streamer capacity. Read more
Pacific Explorer
Previously built as the Shell America, she was owned and operated by Shell prior to an extensive refit and upgrade in 1994. On launching the Pacific Explorer became the industry’s first ever six streamer vessel. With one of the most experienced seismic crews in the business, she has built a unique reputation for North Sea operations. Efficient use of limited weather windows, and maximizing production in shoal areas or in areas of strong tidal effects have become her hallmarks. Read more
Atlantic Explorer
As the industry’s second six streamer ship, the Atlantic Explorer became the first vessel to offer full onboard seismic data processing in 1994. Working in Angola during 1996, the Atlantic Explorer became the first six streamer vessel to acquire over 1000 square kilometers of data in a month. Read more
Orient Explorer
Towing four standard streamers, the Orient Explorer is based in the Asia-Pacific region. She is a part of a joint cooperation between DMNG, a Russian Geophysical Contractor, and PGS. Read more
