Title
(EN) RAPID DEPLOYMENT SUBSEA CHEMICAL INJECTION SYSTEM
(FR) SYSTÈME D'INJECTION DE PRODUITS CHIMIQUES SOUS-MARIN À DÉPLOIEMENT RAPIDE
Abstract
(EN)
A rapid deployment, subsea chemical injection skid assembly includes a non-buoyant skid lowered on a weight bearing line from a surface vessel. The skid carries a chemical injection pump, as well as at least one chemical tank in fluid communication with the chemical injection pump. The skid assembly may include a recirculation/mixing system to limit separation or solids drop out of chemicals arising from medium or long-term storage of chemicals in the chemical tank,. The skid assembly may include a seawater filtration system to supply seawater for mixing with chemicals prior to injection. The skid assembly is operable by a separately tethered remotely operated vehicle.
(FR)
Ensemble châssis d'injection de produits chimiques sous-marin à déploiement rapide comprenant un châssis non flottant abaissé sur une ligne de support de poids à partir d'un navire de surface. Le châssis porte une pompe d'injection de produits chimiques, ainsi qu'au moins un réservoir de produits chimiques en communication fluidique avec la pompe d'injection de produits chimiques. L'ensemble châssis peut comprendre un système de recirculation/mélange pour limiter la séparation ou la perte de solides de produits chimiques issus d'un stockage à moyen ou long terme de produits chimiques dans le réservoir chimique. L'ensemble châssis peut comprendre un système de filtration d'eau de mer pour apporter de l'eau de mer pour mélange avec des produits chimiques avant injection. L'ensemble châssis peut être actionné par un véhicule télécommandé attaché séparément.
