From the 25^th of August to September 10^th 2019, JD-Contractor successfully salvaged all the remaining oil and “Ghost nets” from the old tanker wreck Lindenäs off the East coast of Sweden in the Baltic Sea. The operation was carried out in 70-metre water depths by means of both divers and ROV’s. The goal was to do this salvage operation in the most environmentally friendly, safe and efficient way as possible.

In the spring of 2019 Sea War Museum (SWM) together with JD-Contractor and US-based Global Expeditions Group (GXG) performed its first large joined wreck survey expedition to the Baltic Sea. Over a period of little more than two weeks, M/S Cable One covered more than 600 nautical miles in the Baltic Sea, documenting, 33 wrecks.

By the end of 2018 JD-Contractors A/S’s sister company JD Crafts A/S purchased the vessel Maersk Assister from Maersk Supply Services. The vessel has been renamed “Assister” and will be operated commercially by JD-Contractor A/S.

After using the first months of the new year to overhaul all equipment and machinery, the vessel was docked in the beginning of March for its main survey, repaint and overhaul of thrusters etc. This week a changed vessel emerged from the dock to begin its new duties, operating as a part of the JD-Contractor fleet. 

On the 8^th of January one of the 400 kV cables between Denmark and Sweden was taken out of service due to oil leakage from the cable. The 35-year-old cable uses a special oil as part of the cable insulation. The oil is very thin and dissolves over time but still should not be present in the marine environment. Therefore, Energinet immediately contacted JD-Contractor under the framework agreement in relation to contingency repairs of all subsea cables in Denmark. JD-Contractor swiftly deployed several vessels including diving vessels Cable One and Honte to locate and find the leak with divers.

 

Founder of JD-Contractor A/S and Sea War Museum Jutland, Gert Normann Andersen received an honorary membership of the Supporting Association Strandingsmuseum St. George.

On Monday, 9th of July 2018, a fault occurred on TDC cable connection between Rødvig and Rønne (Bornholm). The cable is a Fiber Optic Cable and initial TDR measurements positioned the fault to approx. 17 km from Rønne, in water depths of approx. 45 m.
As part of JDC's agreement with TDC, JDC was called in to do a cable repair spread with supporting tug, equipment and personnel for the exact fault location and subsequently to carry out the repair and re-burial of the cable with divers.

Every so often JD-Contractor participates in various archaeological expeditions. Some of those expeditions have now been documented in the book Oceans of Archaeology edited by Anders Fischer and Lisbeth Pedersen.

In the book you will find passages with archaeological expeditions carried out from our vessels Marcos and Victor using JD-Contractor diving systems.

Siemens Gamesa Renewable Energy A/S have built the Nissum Bredning Offshore Windfarm in Nissum Bredning, close to Thyborøn on behalf of the owners I/S Nissum Bredning Vind.

Siemens Gamesa Renewable Energy A/S awarded JD-Contractor A/S with the contract for the cable installation and pull in of the three inter array cables and the export cable as well as associated activities for the Nissum Bredning Offshore Project.

The project was carried out in three rounds with the HDD installation in May/June 2017, HDPE & Cable Installation in December 2017 and January/February 2018.

In April 2018 JD-Contractor together with Sea War Museum Jutland made the sensational discovery of the German submarine U-3523 from WWII.
The submarine was discovered during the continued registration of shipwrecks in the North Sea and Skagerrak.

Sea War Museum Jutland onboard our multipurpose survey vessel M/S Vina continues the elaborate mapping of all the possible wreck sites across the sea and it was when investigating such a possible wrecksite that we came upon the U-3523.

We have successfully registered and mapped more than 450 wrecks at sea and counting.

In a consortium with NOV Flexibles (a supplier of high quality flexible pipe systems), JD-Contractor A/S just completed the installation of two flexible flowlines incl. PLEM-systems. The two flowline systems were installed leading from the Client`s factory on shore to an offshore loading station in the Bay of Dakar (Baie de Goree). Innovative engineering and good cooperation between NOV and JD-Contractor once again proved to be a successful combination.

During an installation project in Senegal JD-Contractor’s Tug Bauge was called out for an Emergency towing of a General Cargo Vessel in distress. A fire on board the vessel had left the General Cargo Vessel “Nofit” drifting and unable to sail under own power.

In the afternoon of the 23rd of December 2017 Energinet suffered a fault on the transmission cable to Bornholm in the Baltic Sea. This was the third time in 12 years that the transmission cable for Bornholm was damaged by an anchor during the Christmas period. Luckily the effects of this “Christmas Curse” was remedied in record time as a result of the Emergency Repair Framework agreement Energinet upholds with JD-contractor. 

JD-Contractor assisted the Copenhagen Police with a prompt recovery of the Submarine Nautilus, that sank Friday under suspicious circumstances.

JD-Contractor has been awarded the contract for the cabling of the 28MW Nissum Bredning project in Denmark, where Siemens Gamesa will test a variety of its new offshore wind solutions.

JD-Contractor are among the first to implement the new ISO 9001:2015 and 14001:2015 standards.

The audit was carried out by Bureau Veritas at our sites in Kalundborg as well as Holstebro in March 2017. The audit was successfully completed with no non-conformities or observations.
