MEG Injection packages for FPSO

Design starts on two MEG Injection packages for FPSO

October 2019

Calder Ltd has won an order to design and build two subsea lean MEG injection pump units. These pump units will operate in an ATEX Zone 2 hazardous environment on a floating production, storage and offloading (FPSO) vessel, which will process gas, removing the heavier hydrocarbon components. The gas will then be transferred to a floating liquefied natural gas (FLNG) facility.

The units are electrically driven and feature API 674 plunger pumps. These pumps are of a vertical configuration that enables a substantial reduction in footprint. The units will operate at 286 barg with a flow rate of 38.5m3/hour.

The package design will undergo a Design Approach 2 study. Cyclical pressure pulsations in process fluids can create potentially damaging acoustical resonances. Design Approach 2 Studies model and analyse the acoustics of positive displacement pumping systems and their pipework to predict pulsations and vibrations in the system, either confirming that the equipment will operate within accepted parameters, or highlighting issues. It is becoming more common for customers to stipulate the requirement for a DA2 Study.

Each pump unit will be protected by a stainless steel environmental enclosure. These enclosures will feature a fire suppression system and will offer protection from the elements and noise reduction.

These medium voltage pump skids will undergo full, in-house testing in Worcester ahead of their despatch in 2020.
