Engine features for offshore success
Going further safely
The extraction of subsea oil and gas is becoming ever more complex. Reliable propulsion systems are crucial to the safe advancement of every project.
The new frontiers are geological, technological, and economical. The wells are deeper and further offshore, the seas are heavier, the weather colder. These conditions increase the risk of accidents, spills, and fires. Paradoxically, the price of petrol is low, so operations have to be very carefully budgeted. The challenges are present at every stage, from exploration to well decommissioning.Offshore E&P equipment comes in many shapes and sizes, from gigantic production and storage vessels to the smaller drill ships, but it all has one thing in common: It always needs a continuous power supply that is safe, reliable, and efficient. Providing a good power fit for your needs is MAN Energy Solutions’ field of expertise.
The right power fit for offshore solutions
Very sophisticated technology is needed to extract oil and gas in remote, deep waters. Floating production storage offloading vessels (FPSO) and the newer floating liquefied natural gas facilities (FLNG) fulfill three key functions: Treatment of crude oil and gas, storage, and offloading. All three jobs require a continuous power source.
The combination of hydrocarbon processing and marine technology makes health and safety a key consideration for the people who work on FPSOs and FLNGs.
Further aspects to be taken into account are the adaptability of the vessels to different environmental conditions and emission regulations. A reliable source of high-output, high-availability power is critical. And so are costs. That’s why it’s a good idea to use surplus crude oil or waste gas from the wells instead of flaring.
A floating storage offloading (FSO) unit can stay moored at the site of the oil or gas well for years, using an offloading system to transfer the crude oil or gas to shuttle tankers for shipment to refineries. They have to comply with the strict health and safety regulations of the offshore oil and gas industry as well as the environmental legislation.
The success of an FSO project can be affected by many factors including political stability, the remoteness of the well, environmental conditions, and the changing price of gas or oil. In order to do its job effectively, an FSO needs a continuous power supply that is affordable, highly available, and reliable.
Drilling wells is dangerous enough on land, but doing it under water, in harsh weather conditions in remote locations can be extremely demanding. Drill ships and semi-submersible rigs are used for exploration and well development in water depths of up to 3,000 meters. Jack-ups are usually deployed in shallow waters. Whereas fixed rigs do not need propulsion power, drill ships generally also require power for dynamic positioning at the location where they are drilling.
Among the dangers they must avoid are the disconnection of drilling equipment and blowouts. Drilling equipment requires a robust and reliable power source, ensuring safety and efficiency with minimum maintenance. Electrical power generation systems have to be blackout-free and able to handle big and immediate load steps.Go to Four-Stroke diesel electric propulsion
Light well intervention vessels (LWIV) carry out maintenance and other kinds of work on wellheads such as removing debris and deposits or manipulating valves on Christmas trees. Their work results in better exploitation of underwater wells. Semi-submersible crane vessels (SSCV) are used for installing and removing heavy equipment and wells. Dynamically positioned LWIVs can perform light well interventions more cost-effectively than the larger drilling vessels and rigs.
The ships have to face up to harsh weather conditions and the demands of dynamic vessel positioning. In terms of power generation, these ships require efficient and robust GenSets that can handle big and immediate load steps, are quick in emergency start-up, and do not suffer from blackouts.
For decades, we have been investing extensively in the research and development of compression and power generation technologies. The result is a comprehensive product portfolio, unique in its depth and level of innovation. These are products built for the tough requirements of the oil and gas market. For total reliability, absolute availability and uncompromising efficiency.
Modular and standardized compressor package
Our single-lift package is a proven compressor solution for all applications. It is made up of pre-defined components, resulting in lower investment costs and shorter lead times. It offers reduced operating costs thanks to its unrivaled reliability and state-of-the-art condition monitoring. The highly efficient barrel-type compressor is driven by an electric motor or a gas turbine. Its robust design is suitable for exploration and production processes such as gas lift (EOR), gas injection and gas export. Inlet flow rates range from 200 to 230,000 Am3/h and discharge pressures go up to 800 bar.
