Example of Loadout by Dolly LINK SPAN BRIDGE FOR CROSS OVER TO BARGE Clearance between Link Span bridge and jetty shall be maintained 10-200mm along the loadout operation
Example of Loadout by Dolly POST LOADOUT PREPARATION a) Ground will be graded and compacted, any soft spot shall be cover by steel bearing plate b) Any obstruction in loadout route shall be cleared c) Barricated shall be provided along the loadout route d) SPMT shall be assembled to required configuration, function test, pressure test shall be done e) SPMT insert underneath loadout beam / loadout structure. Test lift and confirmed the pressure between 3 points suspension are acceptable, then fastening the cargo to SPMT if necessary. Computer programming for full steering of overall SPMT system (360 degree full steering) f)
Confirmed all grillage support on barge, corrected installed to the designate location, completed weld and NDE cleared.
g) Confirmed barge pre-ballasting in according to calculation and correct ballasting pump setting. h) Confirmed barge mooring i)
Confirmed actual tide level
j)
Confirmed the loadout certificate was obtained from MWS in view of approved for loadout operation
Example of Loadout by Dolly LOADOUT OPERATION a) Start Movement of loadout structure by jacking up the SPMT until the structure cleared from fabrication support. b) Re-confirmed the pressure for all 3 point suspension. c) Start movement from fabrication area to loadout jetty. d) Standby at loadout jetty, waiting the actual tide level. e) Once the actual tide level is meet to the planned in ballasting calculation then start cross over from jetty to barge. f)
Continue the loadout operation, the operation is divided into several steps and between each step necessary ballast changes have to be performed in the same magnitude as transfer of cargo load to barge and tide variation.
g) Ballasting / de-ballasting will be performed according to the pre-arranged ballasting program. h) Barge level as well as trim and heel shall be monitored continuously (shall be within 1% of barge length and width as per normal standard practice) i)
Control clearance between link span and jetty along the operation (10mm minimum, 200mm maximum)
Example of Loadout by Dolly LOADOUT OPERATION (CONTINUE) j)
Once the cargo move to it final position will be lowered down to its support, approximately half load will be transferred from SPMT to its support, then confirm the shimming requirement for all support locations and provide the shim if necessary before lower down fully and 100% load transfer to support.
k) After 100% lower down the cargo to support, SPMT will be retrieved back to shore and making to the end of loadout operation.

Platform Decommissioning Rig to Reef
Artificial Reef providing hard surfaces for encrusting organism such as spiny oysters, barnacles, sponges and corals. A food chain in what becomes a new new marine ecosystem for numerous types of fishes, sharks, sea turtles, spiny spiny lobsters and sea urchins. The fish populations around artificial reefs are so abundant that that many people enjoy going “Rig Fishing” Fishing” or sport fishing to take advantage of the easy catches.
