Extracting oil and gas offshore is a complicated process carried out in a harsh environment. There are around 200 offshore installations, ranging from large structures standing on the seabed, where up to 200 people may work, to smaller floating production facilities that may employ as few as 30. Around 27,000 people are directly employed in oil and gas extraction.

The UK oil and gas extraction industry (referred to as ‘upstream’) covers the exploration, extraction and initial processing of oil and gas (hydrocarbons) from around the UK, both on- and offshore. The industry produces in excess of three million barrels of hydrocarbons a day and contributed over £30 billion to the UK economy last year. The centre of activity for oil and gas extraction is off the coast of Aberdeen, Scotland. Hydrocarbons are, however, produced in other areas of the UK such as the southern North Sea, from around offshore Humberside to Norfolk and Suffolk, and offshore from Liverpool and Morecambe Bays.

Most offshore sites have landfall locations around the coast to where the hydrocarbons are piped for further distribution or processing for export; others offload from the offshore facility to small tankers, which transport the cargo to various onshore terminals for onward transmission. The principal onshore production area is in Poole, Dorset, where the reservoir is under Poole Harbour but produced onshore using environmentally sound methods. There are other lesser-known onshore fields in the UK, such as that in Surrey.

The UK continental shelf is maturing so that its future ability to compete will depend on improvements in performance. This will, in turn, depend on greater collaboration to allow its output to be delivered with the resources available. The UK still has substantial and potentially recoverable reserves of oil and gas, but many current fields are declining, with fewer and smaller discoveries and many technical challenges. This makes the UK a high-cost province so, as other areas around the world open to international oil investment, competition for investment funds is becoming ever tougher.

Gas is delivered to beach terminals. It is checked for quality and energy content, and then enters 275,000 kilometres of steel pipelines, iron and polyethylene mains and services to supply the customers who use it. Complex arrangements govern the buying and selling of gas and its storage.

THE SECTOR AT A GLANCE

More than 6,000 companies are involved in the UK’s oil and gas industry, split into three main types:

1
operators own licences and are responsible for exploration and production

2
drilling contractors undertake drilling operations, and supply personnel and equipment

3
contract service companies undertake specialised support and maintenance roles.
 

The oil and gas industry and the Services

There is no direct relationship between the oil and gas industry and the Armed Forces. Nevertheless, many of the skills required and valued by employers are taught and practised by a number of people in the Services. Generalist skills, such as supervisory management, project management and administration, are sought after, as are all manner of specialists like engineers, divers and cooks. There are also fuel specialists in units, and a few people highly trained in fuel technology.

Working offshore

Working offshore involves two or three weeks on a rig or installation, followed by equal time at home. Everyone works shifts, normally of 12 hours’ duration. They work close to others in places where there is little space to spend time on their own. Working conditions are noisy and dirty; work is outdoors, and involves lifting and carrying heavy weights, and working with powerful machinery. Some of the jobs available are listed in the accompanying box.

JOB ROLES OFFSHORE

Searching

• Geologists locate possible sites and calculate how much oil is there
• Geophysicists map the substructure

Exploration

• Mud loggers (geologists) analyse mud, fluid and debris from an exploratory drilling
• Reservoir engineers assess oil reserves and drilling sites

Drilling

• Roustabouts are offshore unskilled manual labourers
• Roughnecks/floormen carry out the drilling operation under supervision
• Derrickmen work above the rig, handling the drill pipe sections
• Pumpmen assist derrickmen
• Assistant drillers co-ordinate the activities on the drill floor
• Drillers control the drilling team
• Toolpushers oversee the whole operation
• Rig superintendents are responsible for the operation
• Drilling engineers order the drilling programme

Well services

• Operations supervisors oversee the well crew’s activities
• Wireline operators maintain the well and the tools
• Coiled tubing operators use a tube to pump fluids into the well

Production

• Production engineers monitor wells and check efficiency
• Production operators manage the flow of oil
• Control room operators (barge engineers) manage the equipment that reports on production

General operations

• Offshore installation managers are responsible for offshore operations
• Radio operators control movement and communications
• Crane operators and their assistants load and unload cargo, and supervise teams
• Caterers feed and water the crews
• Stewards maintain and clean accommodation
• Divers inspect and maintain subsea structures, often using remote equipment
• Medics deal with minor complaints and major injuries
• Storemen order and hold equipment and supplies
• Mechanics and technicians

Business support

• This includes accounting, legal, IT and administrative roles

The industry is one of the largest employers of divers. Diving also requires life support technicians managing and controlling all aspects of a diver’s well-being in a decompression chamber between or after dives. ROV technicians man two types of ROV: work and inspection.

Entry requirements for the industry

• Minimum age of 18, but the preferred range is 21–30
• Minimum height of 1.63 m (5 ft 5 in)
• Physical fitness
• Not colour blind (for some jobs)
• Relevant employment experience (if possible) and good Services work record

All offshore workers must achieve the minimum industry safety training standards:

• introduction to the hazardous offshore environment
• working safely (including safety observation systems)
• risk assessment
• platform integrity
• permit to work (also called control of work)
• mechanical lifting
• manual handling
• control of substances hazardous to health
• working at height.

Completion of this programme is included on the individual’s Vantage card accreditation and, for this to be maintained, a refresher programme will need to be taken every four years. In exceptional circumstances, an individual who has not undertaken this training may be allowed to work offshore as a ‘green hand’ under the supervision of a mentor.

The current basic offshore safety induction and emergency training course modules are:

• Travel safely by helicopter to an offshore installation
• Live and work safely on an offshore installation
• Respond to offshore installation emergencies.

Follow-up training may include:

• Helicopter safety and escape
• Firefighting and self-rescue
• Emergency first aid.

People with degrees in geology, chemistry, engineering and logistics, and experience in project management, are highly prized. AS-levels or equivalent are required to enter as a technician, while GCSEs or equivalent will give people a start at craft level. There are a large number of N/SVQs to be gained, in subjects including:

• Bulk liquid warehousing
• Chemical, pharmaceutical and petro-chemical operations
• Forecourt operations
• Measurement processes (maintenance)
• Measurement processes (proving, prover)
• Nuclear decommissioning
• Offshore deck operations
• Offshore drilling operations
• Process engineering maintenance
• Processing operations: hydrocarbons
• Refinery control room operations
• Refinery field operations.

Working onshore

Work onshore encompasses a wide range of activities. Scientists and technicians work to produce improved fuels and more efficient energy; while engineers and construction workers build and maintain the plant and pipelines.

Energy supply is governed by complex and sophisticated ICT systems, so technicians, programmers, designers and trouble-shooters are involved. Transporting bulk fuels by road demands specialist transport, licences and safety qualifications.
