Blue Offshore supports its customers with worldwide installation, transport, storage, field jointing and repair solutions for subsea high voltage cable, array cable, flexible pipe and umbilicals. Our mission is to assist international customers with the development of the world’s oil, gas, wave, wind and tidal potentials.

Our solutions include the rental of innovative modular offshore deck equipment. Our full range of rental deck equipment consists of basket carousels and carousels, tensioners of 10 or 15 tonnes, reel hub drive systems up to 400 tonnes, reels, loading towers, roller highways and chutes. We can also provide tailor-made solutions.

The equipment can easily be installed on a wide range of vessels and barges or placed on the quayside. In addition, Blue Offshore supports vessel’s deck and equipment engineering, Finite Element Method calculations, sea fastening and stability analyses, project management and project engineering. We also provide offshore crew to operate the deck equipment during operations and to support mobilisation, hook-up, commissioning, maintenance and demobilisation.

Our basket carousels have a modular design and have variable product carrying capacities up to 5,000 tonnes for dynamic use and up to 7,000 tonnes for static use. The outer diameters of the basket carousels are 15m, 18m and 23m. Our basket carousels are Lloyds’ Register certified.

The basket carousels have an integrated grillage for sheerleg lifting or SPMT (de)mobilisation.
The grillage is strong enough to support lifting the basket carousel in one single lift during (de)mobilisations. We have developed a Lloyd’s certified 15m outer diameter basket carousel that can be lifted loaded with 1,000 tonnes of product. Also our loading towers can be lifted in a single lift. The basket carousels can be converted into reel type carousels.

Cost and risks are reduced due to the modularity of the equipment. It allows flexible product loading and installation schedules with an increased choice of product installation methodologies.

Our projects - Blue Offshore has several years of offshore experience with subsea product handling and installation activities:
>> NKT/Oceanteam requested Blue Offshore to provide a 23m OD - 10m height basket carousel for the onshore storage of NKT cables for the Hornsea Project.

>> Blue Offshore has supported Subsea 7 with the installation of a flexible pipe for ENI OTCP project by providing a modular system, consisting of a 18m OD – 6m height - 2,750 tonnes basket carousel, loading tower and associated equipment, mobilised on HLV SAL Frauke.

>> Saipem involved Blue Offshore in the Zohr 1 Field Development Project. We provided a basket carousel system for the transportation and installation of 3,700Te of offshore umbilicals. The original fill height of the basket carousel of 5.5m was increased to 8m fill height. Also the height of the loading tower was increased to match the height of the basket carousel. The loading arm has been adjusted for terminations handling. The loading tower assembly contains a 10Te tower tensioner with a pivotable upper track. These adjustments have resulted in an overhaul of the system now ready for the 21st century.

>> EMAS AMC (Chiyoda) contracted Blue Offshore to provide a rental 15m OD basket carousel, able to lift 1,000 tonnes of umbilicals, and related equipment. The equipment was used for the transportation, storage and installation of offshore umbilicals for Woodside’s Julimar Development Project. Installation took place with EMAS’ DP3 pipelay vessel Lewek Constellation. This project is a perfect example of the modularity of Blue Offshore’s equipment. Our 23m OD – 8m height basket carousel has been reduced to 15m OD – 4m height. We also provided support with (de)mobilisation, commissioning, umbilicals loading and offshore umbilicals installation

>> Blue Offshore provided Fugro/E.on with an 18m OD basket carousel with two partition walls and related equipment, such as loading tower and deck tensioner, to support the offshore installation of array cables for the Rampion Offshore Wind Farm Project. Again our equipment proved that the modularity concept works. Our 15m OD basket carousel was increased to 18m OD and from a height of 4m to 6m outer wall and 8m inner hub. A special loading arm column was engineered and fabricated to suit the deck layout of the installation vessel Fugro Symphony.

>> Jan de Nul requested Blue Offshore to provide a basket carousel for the temporary onshore storage of cables provided by LS Cables. The scope of work included the provision of a 23m OD basket carousel, loading tower, tower tensioner, 10 tonnes quay tensioner, quay chute, rollers, project management, project engineering, crew for cable respooling operations and an onshore storage quay side.

>> Blue Offshore has supported Subsea 7 with the installation of a flexible pipe for Statoil’s Oseberg Delta 2 project by providing a modular system, consisting of a 23m OD – 8m height - 5,000 tonnes basket carousel, loading tower and associated equipment, mobilised on Subsea 7’s flexlay vessel the Normand Oceanic. This flexible pipe had a weight of 355 kg/m and an OD of 0.489m.

>> Blue Offshore assisted NKT Cables for cable storage. Our provided equipment, mobilised on barge Stemat 92, included a 23m OD – 5,000 tonnes basket carousel, loading tower, 10 tonnes quay tensioner and associated equipment for cable loading, cable storage, cable transport and operational assistance during cable loading.

>> Blue Offshore has provided Norddeutsche Seekabelwerke (NSW) modular deck equipment consisting of two 10 tonnes tensioners for subsea cable jointing operations with the Nostag 10 cable lay barge and the ASV Pioneer cable lay barge for the Baltic 2 project.

>> In the period 2012-2015, Blue Offshore assisted Norddeutsche Seekabelwerke (NSW) with its Baltic 2 Offshore Wind Farm project. Our provided cable installation equipment, mobilised on the CLV Aura, included a 23m OD – 5,000 tonnes basket carousel, loading tower and 10Te deck tensioner for cable loading, cable transport and operational assistance during cable installation.

>> Blue Offshore assisted German offshore constructor TAGU with the replacing of 1,300m of subsea power export cable in the West of Duddon Sands Wind Farm field by providing a Reel Hub Drive System, 9.8m reel, deck tensioner and associated deck equipment. In addition to the specialised equipment, Blue Offshore provided project management services and operational assistance.

>> Blue Offshore has provided Stemat/VBMS with an 18m outer diameter basket carousel with grillage for offshore cable storage for the ABB Nordergründe project. Fabricated in just 10 weeks, the 2,200 tonnes capacity basket carousel provided VBMS with a flexible resource for storing, transporting and installing cable offshore.
