Audacia allseas heavy lift vessel LED Lights

Voltacon supplied LED lighting to Allseas, the offshore heavy lift and pipeline installation contractor, for retrofit across its fleet of construction vessels.

Allseas operates some of the largest offshore construction vessels in the world, including Pioneering Spirit, the biggest construction vessel afloat, along with Solitaire, Audacia, Lorelay, Tog Mor and Calamity Jane. These vessels lift, install and remove large oil and gas platforms and lay subsea pipelines in deep water. The fleet has installed approximately 20,000km of subsea pipeline to date.

The challenge

Lighting on offshore vessels has to cope with salty humid air, extreme temperatures and difficult logistics for supply and repair. Any failure or maintenance job at sea carries a high cost.

The solution

Voltacon designed and manufactured an LED tube compatible with both 230V and 110V AC (50Hz/60Hz), rated for a life expectancy of over 50,000 hours. The failure rate is minimal, with an estimated 0.4% of units expected to fail within 10 years, cutting the need for spare parts and maintenance callouts.

Voltacon also installed remote battery backup systems in place of the existing emergency lighting. Around 30% of the light fittings are now equipped with lithium batteries, extending their life expectancy by 10 to 12 years.

Results

Four of Allseas' largest vessels fitted with Voltacon LED lights in 2017
Entire fleet due to be lit by Voltacon LED lights by the end of 2018
Estimated total exceeding 10,000 individual light fittings
Failure rate of approximately 0.4% expected over 10 years
30% of fittings upgraded with lithium battery backup, adding 10-12 years to their service life
