About This Project

Supply of LED Lights to Allseas, Heavy Lift Offshore Contractors

Voltacon was approached by Allseas, a multi-national company that lifts, installs, and removes enormous offshore structures and subsea pipeline. Allseas owns and operates a versatile fleet of vessels which have been responsible for setting new standards in the pipelaying industry. One such ship is Pioneering Spirit, the largest construction vessel ever built.

Voltacon was awarded one of the biggest contracts in the world to supply LED tube lights to three of Allseas’ vessels: Pioneering Spirit, Solitaire, and Audacia.

The Allseas Group

Allseas area global leaders in offshore pipeline installation, heavy-lift, and subsea construction. Experts in carrying out extensive and complex subsea construction projects, Allseas have their own state-of-the-art fleet of vessels. These specialised ships are designed, developed and built in-house for the single-lift installation and removal of large oil and gas platforms in deep waters, and to accommodate the equipment needed to install long pipelines for the oil and gas industries.

Tons of high power cables must be transported onboard for subsea installations. The fleet is responsible for the successful interconnection of continents and providing countries around the world with the energy they need to thrive.

Allseas’ Fleet of Game-Changing Vessels

The Allseas fleet includes:

Pioneering Spirit, the largest construction vessel ever built, which is designed for working with large oil and gas platforms and record-weight pipelines.

Solitaire, manufactured for massive deepwater pipelines and able to safely work in congested areas.

Audacia, which is exceptionally well-equipped for unconventional structures and can accommodate pipeline of any length and any water depth.

Lorelay, which represents a new generation of offshore pipe laying vessel, thanks to her large storage capacity and high transit speed.

Tog Mor, a shallow water pipelay barge.

Calamity Jane, a trenching support vessel.

The Challenge for Voltacon

Any offshore application for the Allseas Fleet is expensive – and can be logistically problematic. One of the key difficulties involves the ongoing and routine maintenance of basic essentials, such as lighting.

As well as the complications associated with supplying, repairing and replacing lights, other factors must be taken into account. Considerations include the harshness of the environment, the salty humidity of the air, and the extreme temperatures. On top of this, it is a requirement that lights on-board do not cause any distribution, both on the platforms and inside the ships.

The Solution

Voltacon designed and manufactured LED tube lights compatible with 230V and 110V AC voltage (50Hz/60Hz). The LED tube lights we supplied are extremely reliable and have a life expectancy of over 50,000 hours.

As a result, Allseas will reduce, or even eliminate, the maintenance cost associated with lighting on their vessels. The need to carry large amounts of spare parts is removed because the failure rate of Voltacon LED lights is extremely low: only 0.4 percent of the lights will fail in the next 10 years.

The Outcome for Allseas’ Vessels

Voltacon also replaced the emergency lights systems on the vessels, installing cutting-edge,  remote battery back-up. Now, 30 percent of the light fittings are equipped with lithium batteries and the life expectancy of the emergency lighting is increased to 10 to 12 years by using the lithium batteries.

Between 2017 and the first quarter of 2018, Voltacon supplied four of Allseas’ largest vessels with LED tube lights. By the end of 2018, the entire fleet will be lit by Voltacon LED lights.

Allseas has worked on more than 275 projects and to date, they have installed approximately 20,000 km of subsea pipeline. We are proud to be able to play our part in the success of the company and the future of international oil and gas industries.
