Kvaerner is a specialised Engineering, Procurement and Construction (EPC) company. As a preferred partner for oil and gas operators, industrial partners and other engineering and fabrication contractors, Kvaerner is focused on delivering complete solutions to some of the world’s most demanding projects through reliable, effective and flexible execution models.
Kvaerner has extensive experience with delivering EPC-projects in remote locations such as arctic regions. For projects such as Sakhalin I & II, Kvaerner established a local construction site on the Russian coast. We trained and utilised local contractors and thousands of local employees, enabling a high degree of local content and exchange of technology, methods and best-practice HSE standards.
Kvaerner’s Condeep design for Gravity Based Structures (GBS) is the world’s most widely used solution for offshore oil and gas platforms based on concrete substructures. The GBS’s are installed on the seabed and are typically designed with ballast cells in the bottom part of the structure, enabling it to be horizontally and vertically moved and towed to site. This also permits float-over installation of topsides.
At remote locations, nearby pipeline connections are not always available. The cells in the lower part of the concrete structure can function as temporary oil storage where the oil can then be offloaded to shuttle tankers at regular intervals. The solution has proven to be reliable, cost-effective and provide the versatility needed to meet the challenges of each specific project.
As one of the world’s leading suppliers of floating oil and gas platforms, Kvaerner has extensive experience and capabilities for delivering concrete hulls.
Kvaerner offers concrete monohull solutions, such as the Condeep MonoFloater concept. This simple design allows for both cost-effective slip forming of the concrete hull, and deep draft of the hull, which provides buoyancy well below the wave zone. This ensures improved motion characteristics, especially in areas such as the Arctic, which are prone to extreme weather conditions.
Our documented experience shows the floating concrete platforms have excellent performance with respect to all key parameters, including motion characteristics, virtually no maintenance and minimal down-time.
