INTRODUCTION Engineering and fabrication of brine system for tanks 21 and 31. Purpose of project is to design and fabricate a DN65 piping that would be connected to the inlet manifold of Tank 28 and tank 31 for brine system injection into the tanks. Tanks are designed to connect to a single manifold via a DN250 removal spool. The removable spool is to be temporary dismantled to enable the connection of the new DN65 interconnecting piping spool at each inlet end for the two tanks. The piping shall be commingled at a TEE and routed to the discharge nozzle of a new centrifugal brine pump to be installed on the deck. The inlet of the pump shall be routed from the deck through steel penetrations that shall be provided to a new flange that shall supply the brine to the pump. A flanged spool on the supply line shall also be temporary dismantled to enable connection of a new spool that will link the pump and the brine supply line. Service: brine System Purpose:

piping spools for temporary injection of brine into crude storage tank.

Checklist Checklist Observation Recommendation Inspect existing piping and Tanks 29 and 31 are in confined equipment space. Access to tank is not easy. Review route

possible

piping Piping will be routed to make use of existing supports. Where there are not, new support would be constructed. Piping will pass through penetrations from deck to deck. Piping would be routed through 2 decks and two sections on same deck. Inspect Tie-in Point The removable spools where inspected. Evaluate existing support Few support, new ones need to for possible anchorage be constructed Take physical Confined space constraint. No measurements permit to work Collect documentations P&ID for tanks from company man Interact with company man
