CHI(Guangdong) has completed the project of MARJAN, a series of semi-submersible offshore conversion project, with 5 chute conversions, 12 days ahead of schedule. In the process of undertaking the project, CHI(Guangdong) adjusted the resource allocation in a timely manner, which guaranteed the early delivery. This series of projects involve about 7,000 tonnes of steel structure, involving 3 vessels.

The MARJAN slipway project involves prefabrication, transfer and disassembly of 220 segments for 3 vessels. Before fixing the segments, the project team used the ultra-high pressure water robot to remove the paint, which, on one hand, eliminated the safety risk of fire, and on the other hand, increased the efficiency by about 20 times. The MARJAN slipway project lasted 270 days and achieved the goal of 300,000 man-hours without injury.

The total length of welded seams of MARJAN slipway series project is more than 130,000 meters, the total length of UT is more than 30,000 meters, with a pass rate of 99.2%; the total length of MT is more than 110,000 meters, with a pass rate of 99.96%.

Vessel “Xianghekou” is the largest vessel in MARJAN slipway project, with a single vessel capacity of about 3,500 dwt. CHI(Guangdong) undertook this project with 3 vessels and 5 modifications, and finally each modification was completed earlier than planned, which was highly praised by the shipowner.
