Dutch hefty lift company Hereema Marine Contractors has actually checked what it states is a cutting edge brand-new method of hefty training offshore using 2 dynamically-positioned vessels, 4 large cranes, and also a mixed lift ability of greater than 20,000 statistics lots.

The supposed “QUAD” training method was created internal by Hereema as a less complicated, less-costly method for mounting and also getting rid of extra-large topsides or coats offshore.

The very first examination of the method was effectively accomplished onOct 22 in the Gulf of Mexico making use of Hereema’s Thialf and also Balder, which are 2 of the biggest semi-submersible crane vessels worldwide.

For the examination, Thialf and also Balder operated in alongside raise a solitary tons utilizing their 4 cranes and also consolidated training ability of greater than 20,000 tonnes– consisting of Thialf’s 14,000 t lift ability and also Balder’s 6,400 t ability.

In the future, the complete ability making use of the QUAD method will certainly made higher with the arrival of the 20,000 t ability Sleipnir presently incomplete at Sembcorp Marine in Singapore.

“We are proud of the excellent test results with two dynamically-positioned vessels with four cranes working in parallel: Thialf and Balder, two of the world largest semi-submersible crane vessels, both owned and operated by Heerema. As soon as Sleipnir, the largest semi-submersible crane vessel ever built, is in full operation, we are ready to perform the ultimate QUAD lift using our two giants with a combined lifting capacity of Thialf’s 14,000 t and Sleipnir’s 20,000 t”, stated chief executive officer Koos-Jan van Brouwershaven of HMC.

The brand-new QUAD training technique and also modern technology was qualified global category culture DNV-GL. Hereema called the modern technology an a vital growth of HMC’s solutions as method to reduced general job prices.

“We are looking forward to this with great confidence,” included vanBrouwershaven “With our QUAD lifting method, we definitely enter a new era with more flexibility and efficiency throughout the entire process – from engineering, procurement and construction up to and including the commissioning and installation of the jacket and/or the topside – with lower project costs as a result.”
