The project is part of Taiwan’s first large multi-megawatt offshore wind farm
As an approved essential service provider, Solis Marine has been granted a blanket exemption from the Singapore Ministry of Trade and Industry (MTI), which allows Solis to continue on-site operations during Singapore’s ‘circuit breaker’ measures. introduced to limit the local spread of Covid19.
When travel restrictions prevented Jumbo Offshore from deploying its Netherlands-based offshore team to Singapore to prepare for the mobilization of its heavy lifting crane vessel, Solis Marine was well placed to help Jumbo Offshore overcome a difficult set of challenges. and keep the project on track. .
Yunlin Offshore Wind Farm
Heavy-duty transport and offshore installation operator Jumbo Offshore has been awarded a contract for the transport and installation of wind turbine generator substructures for the Yunlin Offshore Wind Farm, a renewable energy project for the Taiwanese government.
The project is 73% owned by wpd and 27% by a consortium led by Sojitz Corp, which also includes Chugoku Electric Power, Chudenko Corporation, Shikoku Electric Power and JXTG Nippon Oil & Energy Corporation. Yunlin is located eight kilometers from the west coast of Taiwan. When completed, it will be Taiwan’s first major multi-megawatt offshore wind project.
Jumbo’s Challenge – Solis’ Solution
For transport, Jumbo Offshore deploys several vessels from its heavy transport fleet. For the installation, it deploys its 144-meter DP2 offshore installation vessel “JUMBO JAVELIN”, a dynamically positioned heavy lifting crane vessel.
To equip and prepare the vessel for the requirements of the project, several modifications and upgrades were necessary. To manage this, Jumbo Offshore had assembled its Netherlands-based team of in-house offshore professionals and engaged several suppliers and sub-contractors who would travel to Singapore to carry out the mobilization.
When Covid-19 safeguard measures were introduced preventing international travel, Jumbo Offshore approached Solis Marine in Singapore for local on-the-ground assistance.
As an approved essential service provider, Solis Marine is able to continue operations on site in Singapore.
For mobilization, Solis Marine provided a technical superintendent/project manager and a harbor master/mobilization supervisor who worked closely with an electrical engineer who was hired locally by Jumbo Offshore.
From the start of the project in late April 2020 until its successful completion in June, the Covid-19 lockdown in Singapore presented a series of challenges. A significant increase in coronavirus cases among foreign workers living in local dormitories has led to a shortage of available welders, fitters and electrical engineers and the closure of most shipyards.
In addition, several specialist contractors in three other countries were unable to travel to Singapore, meaning that local contractors with the necessary blanket exemption from MTI had to be sought out and engaged.
Close cooperation and coordination with the Dutch Jumbo Offshore team and its contractors based in the Netherlands, Denmark, UK and Singapore overcame many obstacles, leading to the successful mobilization of ” JUMBO JAVELIN” for his mission.
In the final stages of mobilizing ‘JUMBO JAVELIN’, Solis Marine has also assisted Jumbo Offshore in the leasing and mobilization of an Anchor Handling Towage Supply (AHTS) vessel which will assist ‘JUMBO JAVELIN’ on the project.
Managing the project on behalf of Solis Marine in Singapore was Captain Sjoerd Blomsma who said “Solis Marine was delighted to be appointed by Jumbo Offshore to assist in the mobilization of ‘JUMBO JAVELIN’ in Singapore for their upcoming project. . Thanks to close cooperation and teamwork, this was successfully achieved despite a difficult period of confinement.
Ad van Langeraad, Technical Department Manager at Jumbo, agrees wholeheartedly: “Solis has been a great help in maintaining a high degree of efficiency and finding solutions.”
Blomsma continued: “We have explored and applied alternative solutions where necessary, which means that the time lost on the project due to Covid-19 factors has been kept to a minimum. We wish Jumbo Offshore, the captain and crew of ‘JUMBO JAVELIN’, who contributed significantly to this successful mobilization, a safe and successful project ahead.
The main mobilization scope included:
- Positioning and installation of five Offshore Wind Transition Piece (TP) grids.
- Installation on board Jumbo’s Offshore Accommodation (JOA), additional lifeboats, life rafts, Fast Rescue Craft (FRC) and certification by Lloyds for ‘JUMBO JAVELIN’ to accommodate 72 additional offshore professionals for the duration of the offshore installation project .
- Installation on board, modification of the sling tackle and re-certification by Lloyds of Jumbo’s modular Fly-jib, allowing an extension of the lifting height of the vessel’s crane with an impressive lifting capacity of 700 t WLL.
- Installation of six additional containerized generators, one switchboard container, two fuel containers and cable installations as part of an electrical upgrade to provide additional electrical power to the vessel’s DP2 system.
- Extension of the ship’s working deck on the port and starboard stern.
- Installation of four anchor handling winches and their control system forming part of an extended anchor berth to enable the “JUMBO JAVELIN” to perform offshore installations where shallow water depths do not permit use of the ship’s DP2 system.
- Installation of a modular grout (cement) mixing and pumping station in the aft part of the hold.
- Provision of a grout bag storage area, including the installation of a wall barrier for safe evacuation passage and a forklift barrier to ensure safe operations.
- Installation and commissioning of a modular and motion-compensated telescopic access bridge (TAB), allowing access from ‘JUMBO JAVELIN’ to the TPs during installation.
