Quel régime assurantiel ?
Assurances Terrestres vs. Assurances Maritimes
• Typology of offshore wind claims • CAR Claims statistics 2002 –2015 • OAR Claims statistics • Presentation of 5 example claims
LWI - Presentation
• Typical 500MW Offshore Wind Farm • ECV = EUR2.2bn • Cables = 11% of project Capex • EML = Loss of transformer platform

• 40% of Construction claims are cabling related • Cable claims amount to 83% of the total costs paid by Insurers • Poor workmanchip & mechanical damage is the prodominant cause of cabling
losses
CAR Claims 2002-15
• 57 of the last 60 offshore construction projects have experianced cable claims
• Cable claims account for 40% of the losses during construction and 83% of the costs:
• Avg claim: EUR 2,250,000 • Inter-array: EUR 1,250,000 – 3,750,000 • Export cable: EUR 7,500,000 – 25,000,000
• Vessel costs are a major contributor (EUR 100,000 – 250,000 p/day) for a CLB / Jack-
up
CAR Claims 2002-15
OAR Claims statistics
• Offshore wind relatively new industry, so portraying operational loss data requires a projected model.
• Majority of losses would relate to component damage or failure. Includes wear and tear.
• Increased Mechanical damage compared to electrical
• Less frequent and severe workmanship claims
• Defects may be latent, manufacturing or design orientated
• Not including BI
Claim example 1
Claim – circa EUR 4,200,000 Damage – 132kV Export Cable/joint Cause •Lifting frame was incorrectly hooked up to manoeuvring points and not lifting points •Manoeuvring points failed dropping the cable and frame
Lessons Learned •Operators were not familiar with the frame and its safe operation •The lifting points were not clearly colour coded which is good practice
Claim example 2
• Claim: circa EUR 24,000,000
• Damage: Failure of 132kV export cable near OSP
• Cause : lack of earthing on the offshore FOC end
• Lessons Learnt: clear responsibilities need to be defined, extensive electrical check list required
Claim – circa EUR 8,000,000 Cause •Small weather front which was un-forecast came through the area giving unexpected direction and wind speed. The barge was in survival position, but was not able to survive the almost-beam-on winds and swells from this unexpected system
Damage - Significant damage to Export cable & Plough Lessons Learned •MWS provided strong recommendations to consider seeking shelter, Barge Master decided to continue
Claim example 3
Claim – circa EUR 35m (cables, deck equipment, carousel) Cause •Loose or missing hatch covers, flooding of the ballast tanks
Damage – total loss of 2 x Export cables in 3000m+ of water Lessons Learned •Importance of MWS suitability and towage survey
Claim example 4
Subject to the terms and conditions of the Policy Underwriters shall indemnify the Assureds in respect of loss or damage resulting from a fault, defect, error or omission in design, plan, specification, material or workmanship of the same nature, after application of the deductible …according to the following scale: 100% of the first loss amount. 75% of the second loss amount. 50% of the third loss amount. No liability hereafter for third and subsequent loss amounts.
