Overview
Grup Servicii Petroliere, commonly known as GSP Offshore or GSP, is a Romanian oilfield-services company established in 2004. It is a member of the privately held UPETROM Group, whose wider activities include onshore and offshore drilling, oilfield-equipment manufacturing and tourism. GSP focuses primarily on integrated offshore services for the oil and gas industry and combines drilling, marine transportation, offshore construction, well services, engineering, subsea work, hydro-technical construction and specialist training. The company’s offshore drilling fleet consists of seven jack-up rigs: GSP Atlas, GSP Prometeu, GSP Saturn, GSP Orizont, GSP Jupiter, GSP Fortuna and GSP Britannia. The rigs are cantilever-type units and have been subject to an equipment-modernization program. GSP has also operated multifunctional vessels, a medevac vessel and floating cranes, allowing it to provide marine support alongside drilling and construction capabilities. The company’s reported investment program included the acquisition and modernization of vessels and drilling rigs, with more than $500 million invested since its establishment according to the cited reference material. GSP’s offshore-construction activities include the fabrication and assembly of steel structures at the company’s dedicated shipyard facility. Its capabilities cover jackets, decks, accommodation modules and modular platforms, as well as related installation and project-support work. In subsea services, GSP has developed capabilities based on remotely operated vehicles, high-technology survey systems and saturation-diving equipment. These services include subsea installation, inspection, maintenance, surveying, saturation diving and underwater engineering. The company also offers well-services support, including well stimulation and workover planning and operations. Its offshore-wind offering extends the marine and construction platform into renewable energy, with services described as covering general contracting, fabrication, installation, logistics, maintenance and project management. Training is another part of the business. GSP Training Center was established in 2009 and provides courses related to drilling and maritime regulations. The center uses a DrillSIM-600 drilling simulator and launched a cadet program in 2010 for graduates in oil and gas, marine and mechanical engineering, hydro-technical and civil engineering, and electronics. GSP is also associated with the International Association of Drilling Contractors. Its quality, environmental, occupational-health and maritime-safety management systems have been described as audited and certified against ISO 9001, ISO 14001, OHSAS 18001 and the ISM Code by Germanischer Lloyd. The company integrated an SAP application in 2006, indicating an early effort to standardize and coordinate its operational systems. GSP’s positioning is that of an integrated offshore contractor rather than a single-service drilling operator. Its combination of rigs, vessels, fabrication, subsea expertise, well services, logistics and training enables it to participate across several stages of offshore energy projects.

History
Grup Servicii Petroliere was established in Romania in 2004 as an offshore-services company serving the oil and gas sector. From its formation, the business developed around the operation and support of offshore drilling rigs and expanded into a broader integrated-services model. It became part of UPETROM Group, a private business group with interests spanning onshore and offshore drilling, oilfield-equipment production and tourism. A significant element of GSP’s development was the accumulation and modernization of offshore assets. The company operated seven cantilever jack-up rigs—GSP Atlas, GSP Prometeu, GSP Saturn, GSP Orizont, GSP Jupiter, GSP Fortuna and GSP Britannia—and also used multifunctional vessels, a medevac vessel and floating cranes. Its stated investment program focused on acquiring assets and upgrading onboard equipment. The cited reference material reports investment of more than $500 million in vessels and drilling rigs from 2004 onward, although it does not provide a detailed annual breakdown. GSP broadened its activities beyond drilling. Through offshore construction, it fabricated steel structures such as jackets, decks, accommodation modules and modular platforms at its dedicated shipyard facility. Its engineering and marine capabilities supported construction, installation and other offshore project requirements. In well services, the company provided planning and operational support for stimulation and workover activities. It also developed subsea capabilities through remotely operated vehicles, advanced survey and saturation-diving equipment, enabling installation, inspection, maintenance, survey and underwater-engineering work. The company’s management and operational infrastructure also developed during its early years. GSP integrated an SAP application in 2006. It established the GSP Training Center in 2009, offering drilling and maritime-regulation courses supported by a DrillSIM-600 simulator. In 2010, the center introduced a cadet program aimed at graduates in energy, marine, mechanical, civil, hydro-technical and electronics disciplines. These initiatives complemented the company’s need for specialized offshore personnel and provided a formal training channel for technical entrants. GSP’s management systems were described as audited and certified by Germanischer Lloyd against ISO 9001 for quality, ISO 14001 for environmental management, OHSAS 18001 for occupational health and safety, and the ISM Code for maritime safety management. The company also became a member of the International Association of Drilling Contractors. These affiliations and certifications supported its presentation as a structured offshore contractor operating across drilling, marine, construction and subsea disciplines. Over time, GSP added offshore-wind services to its portfolio. The offering was described as a one-stop package covering general contracting, fabrication, installation, logistics, maintenance and project management. This represented an extension of the company’s offshore industrial capabilities into renewable energy, while retaining the marine, construction and project-coordination competencies developed for oil and gas. The available source material does not establish the company’s current fleet deployment, recent ownership changes, executive leadership or financial performance.
