Reservoir basket with integrated hose reel for barrier-testing a multiphase flow meter

A North Sea operator who had previously completed a similar operation with Envirent in 2022, came back for a reliable pumping solution to flush and barrier‑test a multiphase flow meter. Envirent converted a standard Center Pole Basket into a custom reservoir basket with an integrated hose reel.

The reel replaced loose hoses on deck and kept the operation tidy. The reel served as a spool for the injection hose, while a Dynaset 220 bar jetting unit handled cleaning and flushing – a high‑pressure jetter designed for subsea cleaning, supplied complete with lance and hoses. The team also installed a battery cannister and subsea display for monitoring.

Two technicians from Envirent joined the vessel and supported the client throughout the ten‑day campaign in August. A factory acceptance test was carried out beforehand to ensure the reel and modules worked as expected. The reservoir basket has a 1100L fluid tank and an ROV‑friendly pump system that reduces costs and HSE risk by removing surface equipment supporting both pumping and flushing operations.
