Amarinth deliver complex skid package on short lead time to Mariner


Amarinth delivers complex “plug-and-play” API 610 pump skid package for the Mariner Platform in the North Sea

Amarinth, a leading company specialising in the design, application and manufacture of centrifugal pumps and associated equipment to the Oil & Gas, petrochemical, chemical, industrial and power markets, has delivered a complex skid package with an API 610 OH2 pump for a water treatment package for a de-sanding application to be used on the Mariner platform in the North Sea.

The Mariner field is located 140km southeast of the United Kingdom Shetland Islands in a water depth of 110m and is ranked as one of UK’s largest undeveloped oil finds. The required skid package for the platform was constrained by an existing project which was already well underway. The specification was for a 3.6m x 1.5m skid to house the pump, seal support system and all associated pipework, monitoring and ancillary equipment. This all had to be contained within the skid footprint with hook-up and piping termination points to the platform already determined. Furthermore delivery was required in just 38 weeks.

The short lead-time led to an evolving scope to fit the specified duty and space constraints with Amarinth advising on the pump selection, packaging and design considerations to fit with the existing infrastructure. This involved complex pipework to stay within the footprint without generating excessive losses, ensuring no loads or movement was projected to the existing pipework on the platform and maintaining serviceability around the skid package.

Finite element analysis was used to evaluate the fixed pipe loads, ensure their structural integrity and make sure no loading would be passed through to the platform’s pipework. To prevent any movement being transmitted to the connecting pipework during start-up, operation and shutdown of the pump, a sliding baseplate was engineered using a PTFE layer in the baseplate, isolating the movement of equipment on the skid from the platform.

To protect the pump during low flow situations, a flow meter and low flow bypass control valve were incorporated and heat tracing was installed for frost protection. With all of the ancillary components such as terminal boxes, switches, flow meters and control valves that are usually placed off the skid having to be contained within the footprint, Amarinth used human factor software to position cable trays, gratings and walkways and simulate human movements to ensure operators and maintenance engineers could complete their tasks unhindered in and around the skid.

The final “plug-and-play” skid package, which also incorporated a unique lifting frame carefully designed for the stresses involved in correctly positioning the skid in the water treatment package on the platform, has just been delivered on-time.

Oliver Brigginshaw, Managing Director of Amarinth, commented: “Our willingness to look at the most demanding of problems, combined with our engineering agility to design bespoke skid packages on short lead times, ensured that we were able to deliver a pumping solution that met all of the challenging criteria for this water treatment package within the timescales required enabling the overall project schedule to be maintained for the end-user.”

Amarinth Pump Manufacturing

Amarinth is a carbon net zero organisation delivering world-leading expertise in the design, application and manufacture of centrifugal pumps and associated equipment for critical applications in many of the most arduous and hostile environments around the globe.

Founded in 2002, Amarinth has harnessed the skills, creativity and passion of people who have worked in the pump industry for decades, delivering bespoke API and ISO pumps primarily to the offshore and onshore oil & gas industries; nuclear and renewable energy generation; defence; desalination; process and industrial markets.

The company’s innovative approach, business agility and use of sophisticated computer applications enables it to deliver robust, reliable and sustainable pumping solutions on the shortest lead times in the industry.

Process pumps – API 610, API 685, ISO 5199 horizontal, vertical and in-line bespoke process pumps, including ones that are hydraulically and dimensionally interchangeable with the former Girdlestone and other obsolete pumps.

Skid packages and modules – Supplied with a variety of drives for applications including de-sanding, mixing, filtration and chemical injection and tailored for the oil & gas, water treatment and power generation industries.

Condensate recovery – Cutting-edge design providing low NPSH up to 98°C with variable speed drives to reduce cycle time and lower operating costs, available in stainless steel, galvanised or copper tanks for light or heavy industrial uses.

Seal support – Integrated pressurised and vented seal support systems designed and delivered to API 682 and ISO 5199 standards and specific site specifications and requirements, working closely with AES, Eagle Burgmann, John Crane and Protect System.

Spare parts – Critical spares for all Amarinth pumps and related components can be dispatched the same day, reducing potential downtime, and in addition components for the former Girdlestone and other obsolete pumps can be re-engineered often improving the performance of existing assets.

Services – A full range of pump related services, delivered from UK head office or on-site globally, onshore or off-shore, including full commissioning and start-up support; also strip, report and refurbishment of any pump regardless of manufacturer.

Amarinth operates globally from its base in Rendlesham Suffolk, United Kingdom and offices in the Middle East and Malaysia with a global customer base, including BP, Shell, ADNOC, NOV, ExxonMobil, Schlumberger, COSCO, EDF, GlaxoSmithKline, Saudi Aramco, Pfizer, Diageo, Kuwait Oil Company, AMEC, Fluor, LUKOIL, Halliburton, and Babcock.
