PG Marine – Supplier of Cargo Pumps and Systems to the Offshore Oil and Gas Industry

PG Marine works within the oil and gas offshore and maritime industry as a supplier of cargo pumps and systems. They offer systems engineering, integration and packaging based on world-class products and technologies.

Their patented PG-MAPS system can handle liquids ranging from effluent chemicals, through mud and slop to extreme masses such as drill cuttings. It is a simple, compact, energy efficient solution for supply vessels and drilling rigs.

Oil & Gas

Oil & gas operations are essential to the world economy, with many nations depending on them for their energy needs. The industry is facing significant challenges, including a shift from fossil fuels to low-carbon energy sources, as well as increased pressure for environmental sustainability.

Oil and gas production is a multi-stage process that involves discovering a resource, transporting it to a refinery and turning it into finished products ready for sale. The three segments of this process are known as upstream, midstream and downstream.

The industry requires effective managers who understand the complexities and pressures that come with the job. Innovative technologies are helping to transform the industry by improving safety and efficiency, for example by allowing companies to monitor their equipment remotely. New technologies also help to reduce operational costs, lower the risk of accidents and improve employee productivity. Examples include the internet of things (IoT) which promotes better field communication, electronic monitoring and more efficient data management.


The subsea segment of the oil and gas value chain involves installing equipment on the seabed to extract hydrocarbons. The equipment must be highly reliable to make a deep water field development economically viable.

Typically, subsea equipment includes a set of wellheads, risers and associated piping. Production from the wellheads flows to a subsea manifold, where it is commingled before being sent through a jumper to a subsea boosting pump station. The pumps provide the energy to send the produced fluids through flowlines and up to the FPSO deck for processing and storage.

Equipment manufacturers are continually reducing the cost of machinery installed on the ocean floor for deep water projects. They are doing so by streamlining material procurement, optimizing subsea architecture and simplifying equipment installation. These efforts have also lowered the engineering, procurement and construction (EPC) project cycle time to further improve the viability of subsea developments.

Well Intervention

Well intervention is a series of procedures performed on an oil or gas well to address challenges during or near the end of its productive life. Moving parts wear out, seals leak and formation pressures decline. To restore production, operators rely on specialists to perform these well operations.

Typically, these services involve lowering tools and sensors down into the well to repair or diagnose issues with the well. Typical tools are slickline, braided wireline and coiled tubing. These systems can clear a well of sand, paraffin or hydrates; run or retrieve subsurface control valves and gather downhole pressure, temperature and flow data.

Riserless light interventions, meanwhile, use monohull vessels with dynamic positioning capabilities and a subsea BOP to perform wireline and slickline operations without removing the wellhead from the marine riser. These types of operations are important for deepwater wells as expected production gains rarely justify the cost of a workover operation on an expensive offshore rig to remove and replace the completion hardware.

Cargo Handling

With a solid foundation in systems engineering, integration and manufacturing based on world-class products and technology, PG Marine has developed into a major player within cargo handling operations for offshore support vessels. The business can offer solutions ranging from the simplest electric-drive pump, through to fully integrated bridge-integrated computerised, frequency controlled or hydraulically driven systems.

In the oil and gas market, where large, ultra-deepwater tonnage is in demand, PG Marine has a strong focus on developing its own patented cargo systems that can meet demanding requirements. In 2007 this generated a significant portion of a 100 per cent increase in new orders compared with the previous year, and the company expects similar levels of growth this year.

During 2012, PG Flow Solutions received an order to supply a complete liquid cargo system for two multipurpose support vessel (MPSV) being constructed by Fujian Mawei Shipbuilding in China. The system includes pumps, mud agitators and hydraulic power packs.
