Seaway 7 says too soon to say if Alfa Lift delivery will be delayed

It was too soon to say whether a crane problem on a newbuild offshore wind heavy lift vessel would lead to a delay in delivery, renewable energy business Seaway 7 has said.

The Seaway Alfa Lift, which is being built in China by China Merchants Heavy Industry, is scheduled for delivery in 2022.

After the crane incident, Seaway 7 said in a stock exchange update that “we have been informed of an incident involving the folding A-frame on the main crane of Alfa Lift, currently under construction in China. No personnel have been injured and the unplanned movement of the folding A-frame is currently being investigated”.

As reported in IMN yesterday, the ship’s HLC 150000 main crane is manufactured by Liebherr in Rostock, Germany. It has a maximum lifting capacity of 3,000 tonnes at 30 metres, and has been designed specifically to install monopiles and jacket foundations for some of the world’s largest offshore wind turbines.

“The incident is a matter between the shipyard and crane vendor, and it is too early to indicate if this will have an impact on delivery schedule of the vessel,” Seaway 7 said in its update.

Seaway Alfa Lift is a dynamically-positioned, 48,000 dwt heavy lift transport and installation vessel for the offshore wind industry. The design was said to combine the benefits of a semi-submersible vessel with a high-capacity main crane, allowing heavy lift crane operations to be performed with the main deck submerged.

The vessel and crane was initially ordered by Oslo-based Offshore Heavy Transport (OHT). However, this year it combined with the renewables business of Subsea 7 to create Seaway 7, a pure-play renewables company.

In 2019 Alfa Lift was awarded a contract to transport and install foundations for the world’s largest offshore wind farm, the Dogger Bank Offshore Wind Farm, with work expected to take place in 2022 and 2024.

2021-built, Norway-flagged, 65,692 gt Alfa Lift is owned and managed by Offshore Heavy Transport AS.
