Revolutionary Way of Lifting Offshore Successfully Tested
Heerema Marine Contractors (HMC) has developed a globally unique, innovative way of lifting that will redefine the boundaries of lifting operations offshore. This ‘QUAD lifting’ was tested successfully on October 22, 2018 in the Gulf of Mexico. The QUAD lifting enables HMC to integrally install and/or remove oversized topsides or jackets. This revolutionary innovation is an important expansion of HMC's services and guarantees unmatched lower overall project costs.
The unprecedented QUAD way of lifting is suitable for installing topsides on any type of foundation; from jackets to floaters. "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 mT and Sleipnir’s 20,000 mT”, says CEO Koos-Jan van Brouwershaven of HMC. “We are looking forward to this with great confidence. 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.”
The new QUAD lifting method was preceded by a thorough preparation with, in parallel, the certification process for this technology carried out by DNV-GL. Thanks to this QUAD lifting operation, topsides and jackets can now also be designed in a different way with more freedom for the engineers in terms of layout in relation to weight and dimensions. In addition, the QUAD lifting method offers the possibility to build the topside onshore as a total package including the commissioning. This results in substantially lower overall project costs.
Heerema Marine Contractors has signed a new contract to support the construction of a wind farm project, this time in Taiwan. Assigned by the Taiwan branch of Jan de Nul, Heerema will take on the installation of 21 jacket foundations (4 legged) for the Changhua project. The Changhua Taiwan Power Company Windfarm Phase 1 project is situated in Taiwanese waters and is a project of the Taiwan Power Company (TPC) and executed by a consortium of Jan de Nul and Hitachi. The installation will take place 8 km off the coast of Changhua county, at a water depth of 18 to 28 meters.

Dutch offshore contractor Heerema has been assigned to help build the first and largest commercial offshore wind farm in the United States. The prestigious 'Vineyard Wind LLC' project is the nation's first utility-scale offshore wind energy project. Situated 14 miles off the coast of Massachusetts, this project will generate clean, renewable, cost-competitive energy for over 400,000 homes and businesses, while reducing carbon emissions by over 1.6 million tons per year.

This week, Heerema’s newest vessel Sleipnir will begin her maiden voyage. Sleipnir, the world’s largest and strongest semi-submersible crane vessel (SSCV) was built in Singapore and will set course for Spain. The trip will take about 45 days. This unique vessel is the largest crane vessel yet built. It has the strongest pair of revolving cranes and also is the world’s first crane vessel with dual-fuel engines running on MGO and LNG, dramatically reducing harmful emissions.The last two days bunkering of LNG took place 12 miles off the coast of Indonesia. Since LNG is not yet obtainable worldwide, Heerema is the first to perform an LNG bunkering in this area of the world. Heerema has selected Dutch company Titan LNG to help in this undertaking. Titan LNG has chartered a ship commercially managed by Anthony Veder, also Dutch, thus resulting in a unique Dutch cooperation.
