Chinese ports have expanded their towage capabilities with newbuild tugs in response to larger ships entering their terminals
Many have turned to Jiangsu Zhenjiang Shipyard for newbuild tugs and the builder has responded with a series of new deliveries during October. It delivered five tugs and launched four more in the past 30 days ramping up production to meet growing domestic demand.
Zhenjiang Shipyard’s latest delivery in the Jiangsu province involved two azimuth stern drive (ASD) tugboats built for Fuzhou Port. These unnamed vessels, delivered on 28 October, each have overall lengths of 36.5 m, breadth of 10.2 m and depth of 4.6 m, bollard pull ahead of 51.8 tonnes and astern it is 47.4 tonnes. This comes from overall power of 2,942 kW, which gives each tug top speeds of 13.65 knots and endurance of 1,100 nautical miles (nm).
Their delivery came just a week after Zhenjiang Shipyard completed two other ASD tugboats for Ningbo Zhoushan Port Co. Yong Gang Xiao Tuo 7 and Yong Gang Xiao Tuo 8 each have 3,680 kW of power, generating ahead bollard pull of 64.5 tonnes and astern pull of 58.3 tonnes during sea trials. These ASD tugs, delivered on 21 October, have overall length of 41.4 m, breadth of 10.6 m and depth of 4.9 m, a top speed of 13.4 knots, endurance of 1,200 nm and a FiFi class fire-fighting system.
Zhenjiang Shipyard has history of building tugs for Ningbo Zhoushan Port after it delivered an LNG-fuelled tug for the port at the end of 2019.
Just before the start of October, Zhenjiang Shipyard built one more ASD tug for towage in Nanjing Port. Ning Gang 28 was handed over to the owners on 30 September. It has 2,646 kW of power that gives it a speed of 12.25 knots and endurance of 700 nm. It has an overall length of 36.6 m, breadth of 10.2 m and depth of 4.45 m.
In between, Jiangsu Zhenjiang Shipyard group launched and constructed several other tugboats, which will be prepared for delivery in 2021.
On 9 October, the shipyard launched ASD tug Yang Zhou Gang Tuo 4001 as the first vessel it is building for Yangzhou Port. It will have total power of 2,942 kW, similar to the two tugs delivered to Fuzhou Port on 28 October.
Zhenjiang Shipyard launched three ASD tugboats, each with 2,942 kW of installed power, on 30 September including Gang Xing Tuo 235 and 236 for Zhoushan Gangxing and Zhen Gang Tuo 4006 for Zhenjiang port.
Jiangsu Zhenjiang Shipyard group also completed assembly for two 3,676 kW, ASD and fire-fighting tugboats and laid the keel for two 1,912 kW ASD and fire-fighting tugs for Tianjin South Port.
On 16 October, Zhenjiang Shipyard started cutting steel on two ASD tugs, one for Zhangzhou Gulei Tug Co and the other for Xiamen Port.
This followed a quieter September, when the shipyard delivered just one tug, Cao Gang 29 to CaoFeidian Tug Ship Co. That 36-m ASD tug has 2,942 kW of power and ahead bollard pull of 46.5 tonnes.
