Pipe Layer, built in 2001 at Hyundai Mipo, Korea
with 50.687 grt and a length of 207 m
In August 2005 the “CSO DEEP BLUE” underwent a major dry-docking at Fincantieri’s Palermo shipyard for both classification survey and overhaul as well as to allow modification work on the pipe-laying system.
The modification work carried out by HATLAPA included the upgrading of the existing HATLAPA mooring system to allow spooling of pipe under extreme conditions.
This work included the following modifications:
- changing the rope drums from non split type to split type
- changing the original manually operated dog clutches to hydraulically controlled friction clutches
- converting the original manually operated spindle band brakes to hydraulically actuated band brakes
- upgrading the hydraulic power packs to provide high redundancy (including providing each winch unit with its own power supply
- installating a load control system (with sensors build in locally at the winches and at the strong points) incorporating full remote control to allow the mooring functions HOISTING/LOWERING, SPEED CHANGE, CLUTCH IN/OUT, BRAKE ENGAGED/DISENGAGED to be operated safely and easily with JOYSTICK CONTROL plus TOUCH SCREEN in the bridge.
In addition, the specialised vessel mooring using buoys made it necessary to provide so called strong points.
This significant upgrade ensures flexible, efficient and safe positioning during pipe laying.
HATLAPA’s good wishes attend the “CSO DEEP BLUE” on all her pipe laying courses!
