Solis Marine helps Jumbo prepare vessel in Covid-19 workaround

Jumbo Offshore partnered with Solis Marine to prepare its vessel Jumbo Javelin for the transport and installation works at the Yunlin Offshore Wind Farm in Taiwan, after the company’s engineering team itself was unable to board the vessel due to Covid-19. 

For the installation, Jumbo deploys its 144-metre DP2 offshore installation vessel Jumbo Javelin and to equip and prepare the vessel for the project requirements, several modifications and upgrades were required.

To manage this, Jumbo Offshore had assembled its Netherlands based team of in-house offshore professionals and contracted several suppliers and subcontractors who would travel to Singapore to perform the mobilisation. But then Covid-19 hit and the company’s team was unable to travel to Singapore, where the ship was docked for the preparations. 

To solve the issue, Jumbo Offshore approached Solis Marine in Singapore for local on the ground expert assistance.  As an Approved Essential Services Provider, Solis Marine is able to continue on-site operations in Singapore. 

For the mobilisation, Solis Marine provided a technical superintendent and mobilisation supervisor who worked closely with an electrical engineer who was locally contracted by Jumbo Offshore.

From the start of the project at the end of April 2020 until its successful completion in June, Singapore’s Covid-19 lockdown presented a series of challenges. A significant surge in coronavirus cases among foreign workers living in local dormitories led to a shortage of available welders, fitters and electrical engineers and the closure of most shipyards. 

Also, several specialist subcontractors in three other countries were unable to travel to Singapore meaning that local subcontractors with the necessary general exemption from the MTI had to be sourced and engaged.

Close co-operation and co-ordination with Jumbo Offshore’s Dutch team and its subcontractors based in the Netherlands, Denmark, the UK and Singapore, overcame multiple hurdles, leading to the successful mobilisation of Jumbo Javelin for the vessel’s assignment. 

The scope of work included, among other things, the positioning and installation of five Offshore Wind Transition Piece (TP) grillages, the onboard installation of Jumbo’s modular Fly-jib to enable the extension of the vessels crane’s lifting height with a lifting capacity of 700 tonnes,  and the installation of an additional six containerised generators, one switchboard container, two fuel containers and cable installations to provide additional electrical power to the vessel’s DP2 system.

Yunlin Offshore Wind Farm

Jumbo was awarded the contract for the Yunlin offshore wind farm last year by Yunneng Windpower, a Taiwanese subsidiary of WPD. Jumbo’s scope comprises the transportation of 40 monopiles, 120 monopile sections and 40 transition pieces, as well as the offshore installation of 80 transition pieces.

The 640 MW Yunlin offshore wind project is the first large multi-megawatt offshore wind project in Taiwan. It will be developed 8 kilometres off the Taiwanese west coast and will consist of 80 turbines of the 8MW class provided by Siemens Gamesa. The turbines will be installed by Boskalis.
