APPENDIX B APPENDIX B: BULK TRANSFER PROCEDURES
Bl These procedures should be used prior to, during and after, any transfer offshore of
bulk cargo to or from the vessel.
B2 Prior to the start of operations, hoses should be visually inspected and doubtful lengths replaced. Slings and lifting points should also be visually checked and replaced if required. Hoses should only be lifted by a certified wire strop on a certified hook eye fitting. Hoses should be secured to the vessel by a rope lashing before disconnection from the crane. Further rope lashings at appropriate places will minimize 'kicking' of dry bulk hoses in particular.
B3 The following information should be requested by the Installation (or by the Master if bulk is to be transferred from the Installation to the vessel).
- Estimated pumping rate for each product.
(b) Length of warning/estimate of time required to stop.
-
Emergency stop procedure.
-
Confirmation that the lines can be drained back to the vessel's tanks where necessary.
B4 The Master should be provided with the following information:
-
size of hose
-
type of connection
-
length of hose available.
-
colour scheme in operation (hose and/or product).
-
maximum loading rate/pressure permitted.
-
quantities of each product required, the order in which they are required, and an estimate of the time at which they will be required.
B5 When the hose is connected and installation lines are set, the support vessel should be directed to start pumping at a slow rate. For dry bulk transfers, purge air should be utilized prior to bulk transfer to clear lines and prove connections.
B6 If all is well and no leaks are observed, the support vessel should be advised to increase pumping, up to the full delivery rate.
B7 When pumping has finished, both the installation and the support vessel should set their lines to allow the hose to be drained back to the vessel's tank. If the installation has a vacuum breaker fitted to the line, this should be used to aid draining. Lines may also be blown through with air, if available, to ensure that they are properly cleared. In suitable conditions the crane should also be used to lift the hose to aid draining.
B8 When the hose is disconnected, the end should be fitted with a suitable cap or blank.
B9 Every bulk liquid hose should, as far as practicable, be drained back to the vessel's tank(s).
