Around 40 percent of the global oil and gas recovery comes from offshore reserves. With the bulk of new discoveries also expected offshore, increasingly operators are turning to those fields that hold the biggest promise.
Among the most recent FPUs to come on stream are Armada Kraken Pte Ltd, a subsidiary of Bumi Armada Berhad, a Malaysia-based international offshore oilfield services provider and the Western Isles Development Project (WIDP), operated by Dana Petroleum. Other FPUs being supplied are set to operate in the Greater Stella Area, located in the heart of the Central Graben area of the Central North Sea and within the Mariner field, both on the UK Continental Shelf.
For the Armada Kraken FPU, ABB supplied medium and low-voltage switchgear, transformers, medium-voltage variable speed drives (VSDs), uninterruptible power supplies (UPSs) and electrical monitoring and control systems. All are packaged within a prefabricated e-house to protect from the extreme weather conditions encountered in the North Sea. ABB’s scope also includes the automation system, controlling process and marine systems that control the vessel’s routine operations, providing real-time feedback and diagnostic information to its operators.
The vessel was delivered to the oil company EnQuest UK, which began operations at the Kraken field in the East Shetland Basin of the North Sea earlier this year, (2017). The Kraken oil field is the biggest subsea oilfield project in the North Sea with an expected capacity of 140 million barrels of oil and a life of 25 years.
ABB technology and support contracts are being deployed across a series of major floating storage units (FPUs) that have, or will, come on stream within the coming months, tapping into the huge new production capacity in the North Sea.
The Western Isles Development Project (WIDP), operated by Dana Petroleum, comprises two oil fields in the Northern North Sea. ABB supplied wide-ranging equipment, including safety and automation systems (SAS), information management system (IMS), condition monitoring system (CMS) and operator training system (OTS).
The company’s electrical design engineers have optimized the equipment’s internal arrangements to minimize overall footprint. Equipment includes 11 kV and 690 kV switchgear, transformers, high voltage and low voltage VSDs and UPS. Tight integration of these systems is achieved by employing the latest communication standards, IEC61850, ProfiNET, and IED/relay technologies. Sixteen different telecommunications systems are supplied, including a public address system, entertainment, meteorological and a Global Maritime Distress and Safety System (GMDSS).
ABB is responsible for engineering, installation, commissioning and project management of the total automation, electrical and telecommunication package.
Kraken and WIDP North Sea FSUs will be supported by ABB’s extensive service teams and knowledge hub. Service contracts are available and range from integrated control and safety systems (ICSS) healthcare to bespoke VSD service agreements.
