9. Field Operation

During gas and oil production the following input is required:

Human labour for the operation and maintenance of the FPSO and of the subsea infrastructure.

  • Supplies of food, equipment, fuel and chemicals (from local suppliers)
  • Electricity
  • Safety and Rescue
  • Inspection, Maintenance & Repair

Human force

The crew of the FPSO changes once every 4-6 weeks. This can done by helicopter or crewboat. The working hours on board will be 12 hours work, 12 hours rest, 7 days a week.

During the project workers with several skill levels are needed. For the use of medium or low skilled labour, local work force is preferred. In this way the project can contribute to the local economy and the expenses on labour force can be reduced. During the FPSO builting phase, temporary jobs are created for local manpower. Indirect labour is created as all these jobs have to be facilitated by local people.

In total the project will have a demand of approximately 200 permanently medium skilled workers, 500 low skilled workers for construction and additional 500 low skilled people to support.

Supplies of food, equipment and chemicals

For the oil and gas production, certain chemicals are needed (inhibitors, fuel, etc.). These supplies will be delivered by a platform supply vessel. The supply base will be at Vũng Tàu. It is important to have a good functioning PSV, with at least DP2 system and highly trained personnel so the chance of collision with the FPSO is minimal. A cost effective way for getting the supplies on board will be to make a contract with a company that offers such services.
A healthy and tasty meal is served four times a day, this will help crewmembers to remain healthy and motivated.


Power supply will mainly be done by using gas turbinesfuelled by the produced gas. TheFPSO is going to use 60MWe. This means two gas turbines of a total of 60 MWe will be installed. If one of these generators stops working, power is needed to control the valves so production can be safely stopped. For this purpose, two diesel generators with a capacity of 200 kW will be installed.

Safety and Rescue

One of the most important parts of working offshore is safety. Every action has to be done as safe as possible. Therefore, strict regulations are made so that the chance of accidents is minimized. More about safety and rescue can be found in chapter XXXX: HSSE.

Inspection, Maintenance & Repair

IMR is vital to ensure failure free production during the lifetime. A maintenance routine is applied to cover important building blocks of the FPSO. Elements that require regular IMR are:

  • Hull integrity (external + internal)
  • Paint System (external + internal)
  • Ballast System
  • Pipe works (Hydrocarbon, Ballast)
  • Pump System
  • Seals (risers etc.)
  • Tank Venting System
  • Deck Structures (walk ways, plating,)

 5.9. HSSE

HSSE is paramount to the project. The loss of lives is the biggest risk. There also other big risks, such as pollution of the environment. In history there have been many disasters that resulted in loss of lives and huge pollution of the environment. Bloom & Company wishes to prevent such disasters at any cost.
Personal Health
People with a weak personal health have a bigger risk of injury. For example someone with a very weak hearth has a much bigger chance of suffering a heart attack. Thorough medical checks shall be contacted before people can work on the project.
When an offshore worker dies caused by a personal health issue, this still influences the project. Although the cause is not a safety issue, the company’s involved in the project could still suffer reputation damage. On board of the FPSO will be a small infirmary to treat minor injuries. The infirmary should be easy accessible from the main deck. For larger injuries people should be flown by helicopter to the nearest onshore hospital. 
Worker Safety
Most accidents happen during working. Mostly minor incidents, but sometimes also larger accidents occur. Several studies show that up to 80% of the injuries are caused by human errors. This means that it is very useful to work on prevention. Workers will be trained in risk awareness, so that they are aware of risks they might take during working. Also, workers need to be made aware that a clean working space is a safe working space, the risk of stumbling is then minimized. Workers should always wear their safety equipment during working, such as safety shoes, coverall, glasses and hard hats.
Environmental loads
The bow of the FPSO will be connected to a turret. This allows the FPSO to weathervane. The South Chinese Sea is known for typhoons. When a typhoon of class III comes nearby, all offshore structures have to be evacuated. In this case, the FPSO needs to be disconnected and sailed to a safe place. For very high wind loads the equipment and/or mooring lines can be damaged.
The FPSO will have a crew of 50-70 people. These people are very close to a huge turret system and process facilities with highly explosive materials. When the FPSO suffers a big technical disaster, the accommodation should stay unharmed to protect the people. The accommodation is therefore placed at the stern of the vessel while the turret and flaring boom are placed at the bow. This way, the accommodation is as far away from potential hazards as possible. The disadvantage of placing the accommodation at the stern is that the ship has the highest movements at the stern. This can sometimes be uncomfortable for the people, but safety is more important.
Escape routes
The accommodation will always contain the highest number of people. Therefore, the stern of the vessel will contain the highest number of lifeboats to provide an escape route for the high number of people in the accommodation. The whole FPSO will contain the needed safety equipment, such as lifeboats, lifejackets and inflatable rafts. 
Some workers will get a special task during emergencies. During an emergency, they will communicate with each other to keep a good oversight of the emergency and the evacuation of the workers. They will also guide the workers to the lifeboats.
Fire fighting
When working with highly flammable and explosive products, an explosion or fire is a high risk. All the workers will get a basic fire-fighting course. A special team will be trained to cope with larger fires. The superintendent or captain will decide whether the fire is too critical to fight and when to evacuate the ship.
Oil spills are very common around the world. The impact on the environment, depending on the greatness of the oil spill can very big. This should be avoided and measure to content such event should be used. Also, other environmental impact, such as emissions, waste disposal and noise generation should be minimized. To this end, high end process facilities should be used and flaring shall be avoided. Moreover, monitoring of the endanger species and sensitive areas is very important in order to minimize the impact on the local ecosystem. 
B&C strives to be as sustainable as reasonably as possible. Energy efficient machines are used to lower energy usage. Energy usage is also decreased by using a tight schedule so that no unneeded energy is used. The use of paper should be minimized and waste should be separated for recycling.
