Project Description:
LAS BAMBAS 1 | 2
- 04 Square section metal barges, 6.0m x 4.0m x 2.0m, with ballast and venting system. Includes 16” – 200psi valves (Check and Butterfly), quick-opening hatches, hot-dip galvanized grating, railings, zinc anodes, M120 ballast pump and 01 discharge hose type 543, Ø-16”, 200 working pressure.
- 52 2m x 24” floats, for 16” HDPE discharge pipes. Each float located at an average distance of 7m.
- 20 sections of 6m x 1.5m floating walkways, together add up to a length of 120m of floating walkway for maintenance personnel access. Additionally, it allows access to the Conduit pipes and trays for the connection of power and control cables.
- 01 Floating Platform for personnel access and support for winches and anchors Central Electrical Panel (auxiliary equipment). This platform has winches for lifting anchors. The platform allows the parking of the barges at a defined point within the lagoon. The approximate dimensions are: 34m x 2m.
- Shallow Draft Crane Barge – 50 cm – Length 18m x Beam 12m x Depth 0.8m, with 200 HP outboard motor, with Cabin and Hydraulic Rudder. This barge has a Davit System with a load capacity of 5TM. It includes the vertical and longitudinal electric lifting system, as well as 180° radial rotation. Additionally, this barge has a 25Kw generator to feed the motors of the davit system and the ballast pump starter.
LAS BAMBAS-3
- 51 sections of 6m x 1.5m floating walkways, together add up to a length of 306m of floating walkway, which serve as access for maintenance personnel. Additionally, it allows access to the conduit pipes or trays for the connection of power and control cables.
- 03 Auxiliary Pontoons of 4.5m x 4m, which help to fix the walkways. Includes 02 1TM electric winches, with dead weights of 500Kg each. Together (walkways + pontoons) they add up to 201m in length.
- 196 2m x 24” floats for 16” HDPE discharge pipes. Each float will be located at an average distance of 7m. They will be used to keep the 04 sections of 200m each of additional HDPE pipe afloat.
- Electrical equipment consisting of 54 lights, 320m of conductor trays with 100mm lid with three 300mm levels.
- Power Cable (tetra-polar), Submersible, Type SHD-GC-8Kv, 1 AWG, in sections of 200m each, for 900HP motors, 4,160V (medium voltage).
