Offshore crane supports port construction at Incheon New Port

Incheon New Port, located just 40 kilometers west of Seoul, South Korea, is undergoing a major expansion as part of the Incheon New Port Stage 1-2 project. This development aims to increase the port’s capacity and upgrade its facilities to accommodate growing cargo volumes and larger container ships. Upon completion, the new container terminal is expected to boost the port’s handling capacity to five million TEUs by 2030, with the terminal anticipated to be completed by 2025.

Dredging and wharf construction underway

Gwan-Ak Co., Ltd. was appointed to carry out the dredging work and construction of the lower structure of Incheon New Port’s Stage 1-2 container wharf. Established in 1998, Gwan-Ak Co., Ltd. is a South Korean company specializing in a range of construction services, including underwater construction, dredging, reinforced concrete work, earthworks, scaffolding dismantling, and boring grouting. The company has been listed on the Korea New Exchange (KONEX) since 2015.

Offshore lifting operations from vessel

Sitting atop a barge in the Yellow Sea, Gwan-Ak’s SENNEBOGEN 6300 E plays a vital role in the construction of the container wharf. This towering offshore crane is engineered to lift and manoeuvre heavy materials with precision, enabling rapid assembly to maximize operational efficiency.

After the completion of the dredging phase, the crane's precise load handling capabilities are utilized. From offshore, the duty cycle crane lifts and positions heavy-duty concrete framework mould used to create the port apron. Once in their designated positions, the moulds are then assembled and filled with concrete. The crane operates for 8 hours a day, with work sometimes dependent on weather conditions.

As the largest duty cycle crane in our range, the SENNEBOGEN 6300 is a crane with high lifting capacities of up to 300-tons. This makes lifting the large concrete moulds a straightforward task. Its hydraulic lifting system and advanced control mechanisms ensure heavy materials are accurately and efficiently placed.

Proven track record with SENNEBOGEN

SENNEBOGEN sales and service partner, KILWOO Co. Ltd, recommended the SENNEBOGEN 6300 E to Gwan-Ak due to its load-bearing capacity, operational compatibility with the project’s requirements, and SENNEBOGEN's proven track record.

Mounted on a barge and equipped with a 2.5-meter pedestal mount and 46.7m length boom, this crane is Gwan-Ak’s first crane purchase for their own use. It was delivered in 2023 and assembled in South Korea. This marks a change from the usual practice in Korea, where offshore cranes are typically 20 to 30 years old, secondhand and often sourced from Japan.

“SENNEBOGEN duty cycle cranes are renowned for their high performance and reliability. With safe working loads of up to 300 tonnes, the SENNEBOGEN 6300 E is especially well-suited for heavy lifting operations,” says J.H. Choi, Sales Manager from KILWOO Co. Ltd,.“Additionally, the customer appreciates its easy maintenance and accessibility of spare parts.”
