Modular Pump Skid Solutions for Offshore and Hazardous Areas
We have seen a significant increase in demand over the last ten years for compact and modular pump skid solutions, especially for offshore platforms. This trend reflects the growing need for innovative engineering approaches and highly adaptable designs. At Calder, we understand that every offshore project is different. Whether replacing aging equipment or introducing new systems to support platform electrification, our modular pump skid solutions are designed to overcome these constraints. By combining robust engineering with modular flexibility, we help operators minimize the complexity of new equipment installation on offshore platforms.
Calder’s Modular Pump Skid Experience
We have supplied bespoke, modular pump packages to suit a variety of applications and operating locations. This, coupled with our hazardous area expertise, demonstrates why offshore operators continue to look to Calder for their more demanding requirements.
- Proven delivery of skid packages for offshore pump packages for harsh and hazardous environments.
- Pump skid manufacturer with extensive experience of modular and compact pump skids and packages.
- Dedicated documentation team to ensure compliance.
- End-to-end project delivery: from detailed engineering to FAT, commissioning, and service.
Our customer required a modular, triple-pump skid package for an existing, platform in the Norwegian North Sea. The pumped medium is MEG (Mono Ethylene Glycol) and the unit is ATEX Zone 2 and NORSOK compliant. The platform is operational and both access and space are limited, thus presenting the design challenges on which we thrive..
A particularly interesting project was the design and manufacture of two heli-portable well service pump packages. The operating location was on land and was in an area only accessible by helicopters with a 3.5 tonne lift limit.
Not the usual design around access requirements, but a very interesting project is this road-going well service pump system. Built into a 40-ft container, the unit will be transported from one location to another by road. This stand-alone unit features a bulkhead to separate each half of the container into individual modules to allow a safe area section and an ATEX Zone 2 hazardous area section. The pump system is housed in the ATEX section. The safe area section houses a boiler to heat the process fluid to reduce viscosity and facilitate efficient fluid transfer..
This modular TEG pump skid for an FPSO is installed on an FPSO and operates in an ATEX Zone 2 hazardous area.
Included as part of this modular waste injection pump package project was a DA2 (Design Approach 2) Study to model and analyse the acoustics of the pump system and pipework..
Why Modular Pump Skids, Especially Offshore?
Over the last fifteen years, offshore operators have increasingly sought modular pump skids for projects with limited access. The drivers for this are twofold: replacement of existing equipment and the introduction of new.
Replacement of Existing Equipment
As platforms age, so does the machinery and this includes rotating equipment such as pump skids and packages. When platforms are built, installation plans allow pump packages to be introduced in sequence with further machinery following. Years later, sometimes decades, as pump packages near their end of life, replacement pump packages need to be installed. However, with so much machinery in place, access is limited. Thus, the requirement for modular pump packages has been increasing for a number of years.
Introduction of New Equipment
Platform electrification takes two forms. New platforms for which we have supplied many process pump packages. Then there are the platforms being retrospectively modified to operate purely on electricity. For these, we have built significant experience designing and manufacturing pump packages that are modular – tested at Calder, dis-assembled, and then re-built and commissioned on site.
Platform Decommissioning
Platform decommissioning has its own challenges. Limited deck space and often reduced crane lift capacity demand bespoke pump packages. However, modular skids are not always the answer in this application, rather the reduction in weight and size/footprint of units is necessary. In 2016, we developed OffshoreLITE – our range of lightweight and compact pumps, vacuums, and compressors to address this industry need.
